The Chesapeake Bay’s blue crab population has seen a modest rise, increasing 38 percent since the population was counted last winter. While an increase in blue crabs is an indicator of Bay health, the adult female crab population remains below its target, indicating the variability of the blue crab population and the complexities of managing the fishery.
Maryland and Virginia measure the Bay’s blue crab population through an annual winter dredge survey. Over the course of three and a half months, scientists visit 1,500 sites around the Bay, using metal dredges to pull up crabs over-wintering in the mud.
Results of the 2015 winter dredge survey show the Bay’s total blue crab population has increased from 297 million to 411 million since last winter. Results also show the number of spawning-age females has risen from a depleted 69 million to 101 million. The number of juvenile crabs has jumped from 199 million to 269 million, which is just above the long-term average.
According to the Maryland Department of Natural Resources (DNR), the cold winter and resulting low water temperatures contributed to a “substantial mortality” among blue crabs, killing an estimated 19 percent of adults.
“We are pleased that crab numbers increased despite the harsh winter temperatures,” said DNR Secretary Mark Belton in a media release.
The Chesapeake Bay Program tracks the adult female blue crab population as an indicator of Bay health. The Chesapeake Bay Stock Assessment Committee (CBSAC), which includes scientists and representatives from the federal government, state governments and academic institutions, will use this data to make recommendations on sustaining the blue crab population in its 2015 Blue Crab Advisory Report, expected to be released this summer.
A new voluntary education program aimed at increasing environmental literacy was introduced in Virginia on Wednesday.
The Virginia Environmental Literacy Challenge is intended to encourage educators to engage students with the natural world in new and creative ways, by highlighting those who excel in environmental literacy efforts. A series of lesson plans—from habitat construction to recycling projects—will accompany the challenge.
“We need to make sure that our students are graduating with the skills and knowledge they need to protect Virginia’s natural resources,” said Virginia Governor Terry McAuliffe in a release. Governor McAuliffe signed the executive order creating the program.
In supporting the outdoor education and sustainability efforts of teachers, administrators and schools, the program will help achieve the environmental literacy goals of the new Chesapeake Bay Watershed Agreement, signed last year by the Chesapeake Executive Council, the top-level leadership entity for the Chesapeake Bay Program that Governor McAuliffe now chairs.
“Environmental literacy is an important part of the Chesapeake Bay [Watershed] Agreement,” said Molly Ward, Virginia Secretary of Natural Resources and Chair of the Chesapeake Bay Program’s Principals’ Staff Committee. “A systemic approach to environmental literacy will ensure that future generations are prepared to protect and conserve our natural resources.”
Biodiversity—the variety of life on Earth—is key in supporting the complex processes that keep ecosystems healthy, stable and productive, according to a new study from an international team of researchers.
Conserving biodiversity has clear benefits for the plants and animals themselves, as well as the people that rely on these ecosystems and the services they provide. And many studies have found that biodiversity can boost a single function of an ecosystem, such as plant growth or nutrient filtering. But according to Jonathan Lefcheck, lead author of the study and post-doctoral research associate at the Virginia Institute of Marine Science (VIMS), this research is the first to look at how biodiversity supports the suite of complex, interconnected processes essential for a healthy and functioning ecosystem.
Researchers analyzed 94 experiments conducted around the world to examine the relationship between biodiversity and ecosystem health. Their findings show that greater species diversity can benefit multiple functions of an ecosystem. “In other words,” said Lefcheck in a release, “as you consider more aspects of an ecosystem, biodiversity becomes more important: one species cannot do it all.”
A key example of these relationships can be found close to home, in the underwater grass beds of Chesapeake Bay. “Seagrasses are home to a variety of small animals that perform different jobs,” said Lefcheck. “Some control algae that would smother seagrasses. Others keep out invasive species. Still others provide food for striped bass and blue crabs that are served on our dinner tables. By conserving this variety of animals, we can maximize the health of the grass bed, and the benefits to people.”
The study is available through the online journal Nature Communications.
Representatives from states across the Bay region recently signed a cooperative accord that will help reduce the amount of nitrogen flowing from onsite wastewater systems into local waterways.
At the Chesapeake Bay Program office last week, representatives from Delaware, Maryland, Pennsylvania, Virginia and West Virginia signed a Memorandum of Cooperation to share data related to the performance of advanced pretreatment technologies for “onsite wastewater treatment systems,” often called septic systems. Pretreatment of wastewater allows for the removal of potentially harmful pollutants such as nitrogen—but these technologies are often costly, and their approval takes time. Under the arrangement, information-sharing across states will help expedite the approval and deployment of these technologies, as well as offer cost savings to manufacturers and consumers.
Onsite septic systems account for less than five percent of the nutrients flowing to the Bay; advanced pretreatment technologies are expected to reduce nitrogen from these systems by at least 50 percent, as compared to conventional systems. Improvements in wastewater treatment will help achieve the clean water goals of the new Chesapeake Bay Watershed Agreement, which encompasses the Chesapeake Bay Total Maximum Daily Load (TMDL).
For many of the people living upstream of the Chesapeake Bay, daily life doesn’t involve crab pots or oyster dredges. A group of such Bay novices — including one member who had never been on a boat — assembled in Crisfield, Md., this fall to take a ferry to Smith Island, one of the last two inhabited islands in the Chesapeake Bay. Actually a small cluster of low-lying stretches of land, Smith Island and its Virginia neighbor Tangier Island carry a rich cultural history dating back to the 1600s. Over the years, they have been subjected to the extreme weather conditions in the open Chesapeake Bay and forces of sea level rise and land subsidence that have already claimed surrounding islands. The trip, organized by the Chesapeake Bay Program’s Forestry Workgroup, gave the foresters the chance to experience the unique life of a Chesapeake waterman.
“These participants are engaged in work throughout the watershed that directly benefits the quality of the Bay, but often they have very little experience on the Bay itself,” said Craig Highfield of the Alliance for the Chesapeake Bay and the Forests for the Bay initiative, who has facilitated the excursion for the past two years. “This trip is a way to connect their work with a community that relies so intimately with a healthy Bay.”
Over the course of two and a half days, the group of foresters followed educators from Chesapeake Bay Foundation’s Smith Island environmental education center, taking in the unique culture, exploring the changing environment and finding new connections that bring the Bay closer to home.
“I think this group was able to draw similarities between the rural communities they work with — who rely on the natural resources on the land — with this rural community that relies on the natural resources of the Bay,” said Highfield.

Virginia Governor Terry McAuliffe has been selected to chair the Chesapeake Executive Council, beginning January 1, 2015.
The Chesapeake Executive Council, established in 1983, is responsible for guiding the Chesapeake Bay Program’s policy agenda and setting conservation and restoration goals. Members include the governors of Delaware, Maryland, New York, Pennsylvania, Virginia and West Virginia, the Mayor of the District of Columbia, the Chesapeake Bay Commission Chair and the U.S. Environmental Protection Agency Administrator.
“I am humbled that my colleagues on the Chesapeake Executive Council have selected me to lead our collective efforts at this critical time in the restoration of the Chesapeake Bay,” said Governor McAuliffe. “Not only are we engaged in the implementation of the recently signed Chesapeake Bay Watershed Agreement, but we are continuing the difficult work of meeting our water quality goals under the framework of the Chesapeake Bay Total Maximum Daily Load. The Chesapeake Bay is a national treasure and an enormous economic asset for Virginia and our neighboring states. I look forward to working with my counterparts in this region to restore and protect the Bay for generations to come.”
Governor McAuliffe succeeds Maryland Governor Martin O’Malley, who became chair in December 2013. Under the leadership of Governor O’Malley, the Executive Council adopted the landmark Chesapeake Bay Watershed Agreement. He also served two consecutive terms as the Executive Council Chair in 2007 and 2008 and was instrumental in developing two-year milestones that focus on short-term, achievable goals.
"The Bay has been at the top of my agenda during my two terms as Governor and I have been honored to have served as chair three times during my tenure,” said Governor O’Malley. “I know Governor McAuliffe will provide the leadership necessary to meet our collective goals, and I wish him along with the other members of the Council well.”
Rapid population growth and development remain the top threats to the health of the Potomac River Watershed, according to the Potomac Conservancy’s eighth annual State of the Nation’s River report. But the advocacy group hopes implementing smart growth strategies will help the waterway withstand pressure from a growing community.
Despite being listed as the nation’s most endangered river by American Rivers in 2012, the Potomac River’s overall health has improved in recent years. In 2013, the Potomac Conservancy raised the waterway’s grade to a “C” after giving it a “D” grade in 2011. Now, with an estimated 2.3 million new residents expected to move into the communities along its shores by 2040, the Conservancy fears a rapidly changing landscape could undo years of progress toward restoring the Potomac.
“Population growth is likely to bring positive changes to our region including more jobs, higher home values, and a more robust local tax base,” the report states. “But, left unplanned, that growth could also spell disaster for the health of our lands, waterways, and drinking water sources.”
With the region facing forest loss, polluted rivers and streams and an aging water infrastructure, the report offers a range of “smart planning opportunities” as strategies to meet the needs of a growing population without further harming local waters. The Conservancy hopes approaches including forest buffers, mixed-use communities and rain gardens, along with a focus on redevelopment in existing areas rather than new development on untouched lands, will allow for the continued improvement of the Potomac River’s health.
Eight of the top 10 U.S. cities that have seen an increase in “nuisance flooding” alongside rising seas are on the East Coast, according to a new report from the National Oceanic and Atmospheric Administration (NOAA).
Four of the top 10 cities are in the Chesapeake Bay watershed. Annapolis and Baltimore lead the list with a 925 and 920 percent increase in their average number of nuisance floods since 1960. Washington, D.C., has seen a 373 percent increase, while Norfolk has seen a 325 percent increase.
According to the report, nuisance flooding—or minor flooding that closes roads, overwhelms storm drains and compromises infrastructure never designed to withstand inundation or saltwater exposure—will worsen as sea level rise accelerates. Indeed, nuisance flooding has become “more noticeable and widespread” because of rising seas, sinking land and the loss of natural flood barriers.
“As relative sea level increases, it no longer takes a strong storm or a hurricane to cause flooding,” said William Sweet, oceanographer and lead author of the report, in a media release. “Flooding now occurs with high tides.”

The study was conducted by scientists at the Center for Operational Oceanographic Products and Services, who compared data from 45 tide gauges with reports of nuisance floods; whether or not a nuisance flood has taken place is determined at the local level by a National Weather Service threshold. It is hoped the findings will “heighten awareness of a growing problem” and “encourage resiliency efforts in response to” sea level rise.
An understanding of where floods are occurring is integral to building climate resiliency. Once coastal communities know where environmental threats and vulnerabilities lie, they can take steps to move growth and development away from the coast, enhance preparedness efforts to protect human health and protect and restore wetlands, buffers and barrier islands that might shield the shoreline from strong wind and waves.
The Chesapeake Bay Program has set a goal to increase the climate resiliency of the watershed’s living resources and public infrastructure, using monitoring, assessment and adaptation to ensure the region withstands the impacts of a changing climate.
Fisheries experts have recommended a “risk-averse” approach to managing blue crabs in the Chesapeake Bay, following poor harvests and a dramatic decline in the abundance of adult female crabs.

In its annual evaluation of the Bay’s blue crab fishery, the Chesapeake Bay Stock Assessment Committee (CBSAC) urged the Maryland Department of Natural Resources (DNR), the Virginia Marine Resources Commission (VMRC) and the Potomac River Fisheries Commission (PRFC) to protect female and juvenile crabs in an effort to rebuild the overall population. The committee, which is made up of scientists, academics and government representatives and housed under the Chesapeake Bay Program’s Sustainable Fisheries Goal Implementation Team, also recommended establishing sanctuaries to protect females and improving data related to crab harvests and winter death rates.
According to the 2014 Chesapeake Bay Blue Crab Advisory Report, the start of the 2014 crabbing season saw 68.5 million adult female crabs in the Bay. This marks a 53 percent decline from last year’s abundance of adult females. This number is based on the results of the winter dredge survey, and is tracked by the Bay Program as an indicator of Bay health. It is below the 215 million target abundance and the 70 million threshold, indicating adult females are in a depleted state.
“The poor performance of the Bay’s 2013 blue crab fishery—the lowest reported harvest in the last 24 years—combined with the winter dredge survey results that indicate a depleted female population warrants management actions to conserve both females and juveniles,” said CBSAC Chair Joe Grist in a media release. “The cold winter and other environmental factors affected the crab population, and we expect that conservative regulations will help females and juveniles—the future of the blue crab population—rebound.”
Earlier this month, The Capital reported that Maryland, Virginia and the PRFC have promised to cut harvests of female crabs by 10 percent. Virginia announced its plans in June, while Maryland and the PRFC are expected to release their regulations soon.
Scientists expect the Chesapeake Bay to see an above-average dead zone this summer, due to the excess nitrogen that flowed into the Bay from the Potomac and Susquehanna rivers this spring.
Dead zones, or areas of little to no dissolved oxygen, form when nutrient-fueled algae blooms die and decompose. The latest dead zone forecast predicts an early-summer oxygen-free zone of 0.51 cubic miles, a mid-summer low-oxygen zone of 1.97 cubic miles and a late-summer oxygen-free zone of 0.32 cubic miles. This forecast was funded by the National Oceanic and Atmospheric Administration (NOAA) and is based on models developed at the University of Maryland Center for Environmental Science (UMCES) and the University of Michigan.
Dead zone size depends on nutrient pollution and weather patterns. According to the U.S. Geological Survey (USGS), 44,000 metric tons of nitrogen entered the Bay in the spring of 2014. This is 20 percent higher than last spring’s nitrogen loadings, and will influence algae growth and dead zone formation this summer.
Researchers with the Maryland Department of Natural Resources (DNR) and the Virginia Department of Environmental Quality (DEQ) will measure oxygen levels in the Bay over the next few months. While a final dead zone measurement is not expected until October, DNR biologists measured a larger-than-average low-oxygen zone on their June monitoring cruise, confirming the dead zone forecast.
Underwater grass abundance in the Chesapeake Bay increased 24 percent between 2012 and 2013, reversing the downward trend of the last three years.
Because underwater grasses are sensitive to pollution but quick to respond to water quality improvements, their abundance is a good indicator of Bay health. Aerial surveys flown from last spring to last fall showed an almost 12,000-acre increase in grass abundance across the Bay, which scientists attribute to the rapid expansion of widgeon grass in the saltier waters of the mid-Bay and the modest recovery of eelgrass in shallow waters where the species experienced a “dieback” after the hot summers of 2005 and 2010. Scientists also observed an increase in the acreage of the Susquehanna Flats.
“The mid-Bay has seen a big rise in widgeon grass,” said Robert J. Orth, Virginia Institute of Marine Science (VIMS) professor and coordinator of the school’s Submerged Aquatic Vegetation Survey, in a media release. “In fact, the expansion of this species in the saltier waters between the Honga River and Pocomoke Sound was one of the driving factors behind the rise in bay grass abundance. While widgeongrass is a boom and bust species, notorious for being incredibly abundant one year and entirely absent the next, its growth is nevertheless great to see.”
Underwater grasses, also known as submerged aquatic vegetation, are critical to the Bay, offering food to invertebrates and waterfowl and providing shelter to fish and crabs. Like grasses on land, underwater grasses need sunlight to survive. When algae blooms or suspended sediment cloud the waters of the Bay, sunlight cannot reach the bottom habitat where grasses live. While healthy grass beds can trap and absorb some nutrient and sediment pollution—thus improving water clarity where they grow—too much pollution can cause grass beds to die. Indeed, poor water clarity remains a challenge for eelgrass growth in deeper waters.
Until this year, the Bay Program mapped underwater grasses by geographic zone. Now, abundance is mapped in four different salinity zones, each of which is home to an underwater grass community that responds differently to strong storms, drought and other adverse growing conditions. This reporting change “makes more ecological sense,” said Lee Karrh, program chief at the Maryland Department of Natural Resources (DNR) and chair of the Bay Program’s Submerged Aquatic Vegetation Workgroup.
“Reworking our historic data was hard work, but doing so makes it easier to understand patterns in grass growth,” Karrh said.
A new report from the University of Richmond School of Law calls on Virginia to better protect its residents from chemical contaminants, millions of pounds of which are released into the environment each year by industries across the state.
Image courtesy gac/Flickr
The report, authored in part by Noah M. Sachs, director of the law school’s Center for Environmental Studies, examines the sources of chemical contaminants in Virginia and concludes that the Commonwealth should expand its existing toxic chemicals program, empower the Department of Environmental Quality (DEQ) to clean up more contaminated sites and enact legislation and permit conditions more stringent than federal standards.
According to the report, Virginia’s industries released almost 40 million pounds of toxic chemicals into the air, water and land in 2011. While this represents a drop in releases compared to 2010, the discharge of chemicals into rivers and streams remains significant and, in some cases, could impact in the Chesapeake Bay.
The report notes that more than 250 facilities are allowed to send toxic chemicals into Virginia waters, and the state’s tributaries rank the second worst in the nation as measured by the amount of contaminants discharged into them. While some of the worst-ranking tributaries—like the New and Roanoke Rivers or Sandy Bottom Branch—do not drain into the Bay, the James River ranks forty-fifth in the nation for total toxic discharges and ninth in the nation for the discharge of toxics that affect human development.
Contaminants on the state’s land have also had an effect on water: a number of the 31 sites listed as contaminated under the federal Superfund program involve contaminated drinking water, surface water and groundwater.
Virginia is not the sole watershed state that faces contaminated rivers and streams. According to 2012 assessments, 74 percent of the Bay’s tidal tributaries were partially or fully impaired by chemical contaminants.
In a January 2014 editorial published in the Richmond Times-Dispatch, Sachs recommended putting toxic chemical regulation “at the forefront of Virginia’s environmental agenda.” He wrote, “Our report recommends a comprehensive program to protect Virginians, beginning with strict permitting, increased inspections, new state authority to remediate contaminated sites and more funding and personnel.”
The intensive withdrawal of groundwater is causing land to sink in the lower Chesapeake Bay region, worsening the effects of sea-level rise and increasing the severity of floods along the Delmarva Peninsula and Virginia Coastal Plain.

Land subsidence, or the sinking of the land’s surface, is in part a natural phenomenon, occurring as bedrock responds to the melting of an ice sheet that once covered Canada and the northern United States. But according to a new report from the U.S. Geological Survey (USGS), most of the land subsidence in this area is taking place in response to groundwater withdrawal, which could help explain why the region has the highest rates of relative sea-level rise on the Atlantic Coast.
When groundwater is pumped out of the earth, water levels in the area’s underground aquifers decrease. As these water levels decrease, the aquifer system compacts, causing the land above it to sink. In the southern Bay region, land subsidence has been measured at rates of 1.1 to 4.8 millimeters per year—close to the width of five stacked pennies.
Land subsidence can increase flooding, alter wetland and coastal ecosystems, and damage human infrastructure and historical sites. Some areas in Virginia—like the city of Franklin and the counties of Isle of Wight and Southhampton—have already experienced floods as the land around them sinks, and the low-lying Hampton Roads could experience similar episodes soon.
But according to the USGS, a change in water use—from moving groundwater pumping out of high-risk areas to slowing rates of groundwater withdrawal—could slow or mitigate land subsidence and relative sea-level rise.
The James River Association has measured a slight improvement in James River health, giving the waterway a “C” in its latest State of the James report.

The river’s score of 53 on a one-to-100 scale marks a two percent increase since the report was last issued in 2011, but continued problems with sediment pollution overshadow progress made elsewhere.
While sediment is a natural part of the environment, excess particles of sand, silt and clay can cloud the water, harming underwater grasses, fish and shellfish. According to the State of the James report, sediment pollution in the James has shown no improvement over the past two decades, indicating that stronger measures should be taken to restore streamside forests and other buffers that can filter runoff before it enters rivers and streams.
Virginia has made strides, however, in reducing nutrient pollution, as it works to meet limits set by the Chesapeake Bay Total Maximum Daily Load or “pollution diet.” The Commonwealth has invested in wastewater treatment, increased funding toward agricultural conservation and focused attention on controlling stormwater runoff.
Striped bass spawning success has improved in the Chesapeake Bay.

According to data from the Maryland Department of Natural Resources (DNR) and the Virginia Institute of Marine Science (VIMS), the number of juvenile striped bass in the watershed has rebounded from last year, when it was close to the lowest ever observed.
Known as the “juvenile striped bass index,” the number of young-of-the-year striped bass in the Bay is used to track the species’ reproductive success. To count the number of striped bass that hatched this spring, biologists take a series of seine net samples in noted spawning areas, from the Upper Bay to the James River.
Image courtesy VIMS
This year, the average number of juvenile striped bass caught in each Maryland sample was 5.8, which falls below the 11.7 average but above last year’s index of less than one. In Virginia waters, researchers caught more than 10 striped bass per seine sample, which is close to the historic average of 9. A VIMS media release called the results consistent with historically observed patterns in striped bass populations.
Striped bass, or rockfish, hold great value in the watershed: the fish is a top predator in the food web and a critical catch to commercial and recreational fisheries. Late-1980's fishing bans helped striped bass recover from harvest and pollution pressures, and it is now considered a recovered species.
The Chesapeake Bay’s dead zone measured near average in size this past summer, coming close to scientists’ June prediction of a smaller than average hypoxic zone in the nation’s largest estuary.
Dead zones, or areas of little to no dissolved oxygen, form when nutrient-fueled algae blooms die. The bacteria that aid in algae bloom decomposition suck up oxygen from the surrounding waters. The resulting hypoxic or anoxic conditions can suffocate marine life, shrinking the habitat available for fish, crabs and other critters.
Each summer, the Maryland Department of Natural Resources (DNR) and the Virginia Department of Environmental Quality (DEQ) collect water samples to measure the hypoxic volume of the Bay. Since 1983, this number has ranged from 15.3 to 33.1 percent. In 2013, it measured 22.1 percent: 5.6 percent higher than the previous year and just above the 21.9 percent average.
Denser grass beds in the Chesapeake Bay could boost the region’s blue crab population, according to a new report from the Virginia Institute of Marine Science (VIMS).
While researchers have long known that blue crabs use grass beds as sheltered nurseries and feeding grounds, this study is the first to show that denser, higher-quality grass beds hold more crabs than open beds where patches of mud or sand separate plants.
These findings are based on fieldwork conducted between 2007 and 2008, during which scientists used a powerful vacuum to collect blue crabs from 104 sites along the shores of the lower Bay.
Graduate student Gina Ralph led the study and said in a media release that her work suggests “the quality of seagrass habitat can influence the population dynamics of blue crabs on a baywide basis.” But underwater grass abundance has declined in recent years, due to warming waters and sunlight-blocking sediment pollution. Blue crabs, too, have suffered population declines, as pollution, predators and human harvest put pressure on the iconic species.

When the start of a new school year drives students into the library, it’s not always a given that they are looking at books. In fact, one marine research center in Virginia is home to a library filled with fish.
The Nunnally Ichthyology Collection at the Virginia Institute of Marine Science (VIMS) contains more than 100,000 freshwater, estuarine and marine fish specimens for use in research and education. The collection is curated by Eric J. Hilton, an associate professor of marine science who has spent a great deal of his life around collections of fish and reptiles. But this one, he says, is unique: after taking on “orphaned” specimens from two other laboratories, VIMS has become the only institution to actively maintain a collection of Chesapeake Bay and mid-Atlantic fish.
The preservation process starts with the euthanization of the fish. Then, the specimen is soaked in a formalin bath to prevent tissue decay and breakdown.
Once the specimen is completely soaked (larger fish take quite a bit more time to preserve than smaller fish), the formalin is flushed from the body and the specimen is placed in a jar that contains a 70 percent ethanol solution.
Oftentimes, multiple specimens of a single species are collected and catalogued. Because there is always variation in nature, researchers prefer to compare and contrast multiple fish of the same species to gain a well-rounded perspective of what the fish and the area they live in are like. “Looking at [only] one individual from a [single] locality will not give you a good view of that locality,” Hilton said.
Each jar is given its own catalogue number that will follow the specimen far into the future. “With that [catalogue] number comes species identification, and all of the attributes of when and where that fish was caught and how it was caught,” Hilton said. “[The number] is entered into a catalogue that is accessible to people throughout the world.”
VIMS also collects a limited amount of skeletal remains in order to conduct skeletal analyses of certain species. “We hope that someday, people can come to the Chesapeake Bay and ask, ‘What was here in 2013?’ and get to see those species and specimens,” Hilton said. If the collection is properly cared for, its fish could be kept for well over 200 years. In fact, some natural resource libraries in Europe are more than 400 years old.
Because its specimens have been collected over decades, the library contains evidence of changes in the Bay. The southern flounder, for instance, is typically found off the coast of North Carolina and other southern waters. Historically, adult southern flounders have made their way to the southernmost portions of the Bay only during hot summer months when the water is warm. But in recent years, researchers have found young southern flounder in the Bay and have added them to the VIMS collection. This new addition indicates a northward shift of southern flounder spawning grounds, likely due to warming waters and climate change.
The fish collection also stores vital information about the introduction and spread of invasive species like the northern snakehead or blue catfish across the state of Virginia and the Bay watershed. Hilton explains: “We have snakeheads from different drainages, so we can track their invasion. We have some of the first juvenile blue cats, and can get a sense of where and when the invasions start.”
VIMS plans to continue their fish collection efforts for the foreseeable future. After all, as science and technology advance, researchers can conduct new tests on older specimens and learn things about the species or its environment that they might not have known before. “If you stop collecting, you limit what you are able to do,” Hilton said.

A virus that can cause disease and death in largemouth bass has been found in otherwise healthy northern snakeheads taken from two Virginia waterways. According to the U.S. Geological Survey (USGS), the finding raises the possibility that northern snakeheads could be carriers of the pathogen, capable of transmitting it to other fish in the Chesapeake Bay.
The pathogen, known as the largemouth bass virus, has been found in bass, sunfish and other members of the freshwater sunfish family, but largemouth bass are the only fish known to develop disease from it.
The largemouth bass virus appears to attack the swim bladder, causing fish to lose their balance and float near the surface of the water. According to the Virginia Department of Game and Inland Fisheries, the virus has been found in waters across the state, but its impacts are often short-lived and largemouth bass can build up resistance to the disease.
While the pathogen doesn’t seem to affect the health of northern snakeheads, the habitat of this invasive fish often overlaps with that of largemouth bass, which may favor transmission of the virus.
Dead zones are impacting the distribution and abundance of fish that live and feed near the bottom of the Chesapeake Bay, according to new research from the Virginia Institute of Marine Science (VIMS).
Dead zones, or areas of little to no dissolved oxygen, form when nutrient-fed algae blooms die and decompose, and are most pronounced in the deep waters of the Bay’s mainstem during warm summer months. During a decade-long study of the bottom-feeding fish that inhabit this portion of the Bay’s water column, scientists noticed drastic declines in species richness, diversity and catch rate as dead zones restricted habitat and displaced the fish toward more hospitable waters.
So-called “demersal” fish—which include Atlantic croaker, white perch, spot, striped bass and summer flounder—avoid dead zones because a lack of oxygen can place stress on their respiratory and metabolic systems. While the fish often return to their former habitat when oxygen levels improve, dead zones can also wreak havoc on their forage grounds, stressing or killing the bottom-dwelling invertebrates the fish need for food.
“Once oxygen levels go up, we do see the average catch rate go up,” said Andre Buchheister, Ph.D. student and author of the VIMS study. “That’s a good sign. It indicates that once those waters are re-oxygenated, it’s possible for fish to move back in. But the availability of food is compromised, and studies have shown that the productivity of benthic biomass—or the critters that live in and on the bottom of the Bay—is stressed.”
The impact that demersal fish displacement could have on Bay fisheries is unclear, Buchheister said. Commercial fishermen who work outside of the mainstem might not be affected. But recreational anglers searching for striped bass could struggle if their forced move out of cool, deep waters is shown to contribute to poor health among the population.
In June, a forecast from researchers at the University of Maryland Center for Environmental Science (UMCES) and the University of Michigan predicted a smaller than average dead zone for the coming summer, thanks to lower than average nutrient loads that entered the Bay last spring. But to return the Bay’s mainstem to its former health, “one or two good summers won’t make that much of a difference,” said Buchheister. Instead, benthic habitat must be rebuilt, as long-term improvements boost Bay health from the bottom up.

A report on the Chesapeake Bay’s blue crab population reveals a stock that is not overfished and within which overfishing is not occurring.
According to an annual evaluation from the Chesapeake Bay Stock Assessment Committee (CBSAC), the start of the 2013 crabbing season saw 147 million adult female crabs in the Bay, which marks a 54 percent increase from last year’s abundance of adult females. The Chesapeake Bay Program tracks this female-specific reference point as an indicator of Bay health. While this number is below CBSAC’s target, it is above the committee’s overfished threshold.

The 2013 Chesapeake Bay Blue Crab Advisory Report, presented by CBSAC at the June meeting of the Bay Program’s Sustainable Fisheries Goal Implementation Team, is based on the results of the winter dredge survey. This annual estimate of the blue crab population is considered the most comprehensive blue crab survey conducted in the Bay.
To maintain a sustainable blue crab fishery, CBSAC recommends taking a risk-averse management approach and making a 10 percent cut to the 2013 female blue crab harvest. The Maryland Department of Natural Resources (DNR), the Virginia Marine Resources Commission (VMRC) and the Potomac River Fisheries Commission (PRFC) have agreed to pursue the latter recommendation.
CBSAC also recommends better accounting of commercial and recreational harvests and continued efforts to monitor the inactive commercial crabbing licenses in the fishery, which could lead to significant increases in harvest if they were to come into sudden use.

Dead zones, or areas of little to no dissolved oxygen, form when nutrient-fueled algae blooms die. As bacteria help these blooms decompose, they suck up oxygen from the surrounding waters. The resulting hypoxic or anoxic conditions can suffocate marine life.
The Chesapeake Bay Program tracks dissolved oxygen as an indicator of water quality and Bay health.
The latest NOAA-funded forecast from researchers at the University of Maryland Center for Environmental Science (UMCES) and the University of Michigan predicts an average summer hypoxic zone of 1.108 cubic miles, lower than last year’s mid-summer hypoxic zone of 1.45 cubic miles.
This predicted improvement should result from the lower than average nutrient loads that entered the Bay this spring. According to the U.S. Geological Survey (USGS), 36,600 metric tons of nutrients entered the estuary from the Potomac and Susquehanna rivers, which is 30 percent lower than average.
The Bay’s dead zones are measured at regular intervals each year by the Maryland Department of Natural Resources (DNR) and the Virginia Department of Environmental Quality. While the final dead zone measurement will not take place until October, DNR biologists measured better than average dissolved oxygen on its June monitoring cruise, confirming the dead zone forecast.
Cover crops, streamside trees and nutrient management plans: all are exceptional ways to reduce nutrient pollution in the Chesapeake Bay. And for father and son duo Elwood and Hunter Williams, restoring the Bay begins with conservation practices and a shift in mentality.
“We knew coming down the road that we needed to do a better job with keeping the water clean,” Hunter said. “We decided that if there was going to be a problem with the streams it wasn’t going to be us.”
Excess nutrients come from many places, including wastewater treatment plants, agricultural runoff and polluted air. When nitrogen and phosphorus reach waterways, they can fuel the growth of large algae blooms that negatively affect the health of the Bay. In order to reduce these impacts, the U.S. Environmental Protection Agency (EPA) has implemented a Bay “pollution diet,” known as the Total Maximum Daily Load (TMDL).
Since the passing of the TMDL, many farmers in the watershed have felt the added pressure of the cleanup on their shoulders, but for the Williams family, having the foresight to implement best management practices (BMPs) just seemed like the environmentally and fiscally responsible thing to do.
”We don’t want to get to a point where regulations are completely out of control,” Hunter explained. “Farmers know what they’re putting on the ground so we have the ability to control it. Most people who have yards don’t have a clue what they’re putting on the ground when they use fertilizer. The difference has to be made up by the farmers because we know exactly what is going on to our soil.”
The Williams family began implementing BMPs on Misty Mountain Farm in 2006 by teaming up with the Potomac Valley Conservation District (PVCD). The government-funded non-profit organization has been providing assistance to farmers and working to preserve West Virginia’s natural resources since 1943.
The PVCD operates the Agricultural Enhancement Program (AgEP), which has steadily gained popularity among chicken farmers and livestock owners located in the West Virginia panhandle and Potomac Valley. While these two districts make up just 14 percent of West Virginia’s land mass, these regions are where many of the Bay’s tributaries begin—so it is important for area landowners to be conscious of pollutants entering rivers and streams.
AgEP is designed to provide financial aid and advice to farmers in areas that the Farm Bill does not cover. PVCD is run in a grassroots fashion, as employees collaborate with local farmers to pinpoint and meet their specific needs.
“It [AgEP] has been very well received,” said Carla Hardy, Watershed Program Coordinator with the PVCD. “It’s the local, state and individuals saying, “These are our needs and this is how our money should be spent.” Farmers understand that in order to keep AgEP a voluntary plan they need to pay attention to their conservation practices.”
Hunter admits the hardest part of switching to BMPs was changing his mindset and getting on board. Originally, Hunter was looking at the Bay’s pollution problems as a whole, but with optimistic thinking and assistance from PVCD, he realized that the best way to overcome a large problem was to cross one bridge at a time.
It wasn’t long before the Williams family started to see results: fencing off streams from cattle led to cleaner water; building barns to overwinter cows allowed them to grow an average of 75 pounds heavier than before, making them more valuable to the farm.
By using BMPs, the Williams family has set a positive example for farmers across the watershed, proving that with hard work and a ‘sky is the limit’ mentality, seemingly impossible goals can be met.
Hunter points out, “We are proud to know that if you are traveling to Misty Mountain Farm you can’t say, “Hey these guys aren’t doing their part.”

When cold weather arrives, blue crabs up and down the Chesapeake Bay stop their scurrying. The summertime rush of food-hunting and mate-finding is over, and the crustaceans will spend the winter months buried in sand and sediment. It is at this moment that researchers in Maryland and Virginia must strike: to count the crabs while they are still.
Known as the winter dredge survey, this annual count of the Bay’s blue crab population is a critical part of blue crab management. Without an accurate estimate of blue crab abundance, fisheries managers cannot set harvest limits for the season ahead.
“The winter dredge survey is the most vital tool that we have in crab management,” said Chris Walstrum, a natural resources biologist with the Maryland Department of Natural Resources (DNR). “This is the best chance we have to assess the [blue crab] population, because the crabs are stationary.”
Walstrum and his team are responsible for counting crabs in Maryland waters; the Virginia Institute of Marine Science (VIMS) conducts the winter dredge survey in the Virginia portion of the Bay. Between the two agencies, a total of 1,500 Bay sites are visited over the course of three and a half months before the numbers are crunched and fisheries managers can make recommendations on how blue crab harvests should or shouldn’t change.
On a warmer-than-normal January morning, Walstrum is aboard a boat in Broad Creek, a tributary of the Choptank River on Maryland’s Eastern Shore. The DNR vessel has been captained for more than a decade by Roger Morris, a fifth-generation waterman who used to dredge for crabs commercially and whose skills are invaluable to the success of the survey.
“Whether people like it or not, the winter dredge survey is the whole basis for our [blue crab harvest] limits,” Morris said. “That’s why I try to do the best I can do at it. It takes experience. You just can’t walk on a crab dredge boat and expect to catch crabs.”
At each survey site—six of them in this particular waterway—Morris will line up his boat and drop its so-called Virginia crab dredge into the water. The metal dredge is towed along the bottom for one minute before it is hoisted back on board, where the newly caught contents of its mesh liner are dumped out and sorted through. In each catch, there are brown leaves, oyster shells, little fish and, more often than not, a collection of blue crabs.
Each crab is weighed, measured and sexed before it is tossed back into the water. This provides an accurate picture of the blue crab population, as researchers track the number of young crabs that will form the backbone of the fishery next fall and the number of females that will produce the next generation of blue crab stock.
“The winter dredge survey provides us with a cornerstone piece of data from which to operate our [blue crab] management,” said Brenda Davis, chief of the DNR Blue Crab Program.
“It’s a long-running survey, and it’s been consistently accurate,” Davis said. “It gives us a good, static picture of the number of crabs in the Bay.”

The blue crab population in the Chesapeake Bay has dropped, but a substantial boost in the number of spawning-age females has offered officials a piece of good news in spite of this disappointing decline.
According to the results of the annual winter dredge survey, which measures the blue crab population in Maryland and Virginia, the number of spawning-age females in the Bay has risen 52 percent. The Chesapeake Bay Program tracks this number as an indicator of Bay health, and an increase is a sign that management methods to conserve adult female crabs are working. But an overall decline in the Bay’s blue crabs—from 765 million in 2012 to 300 million in 2013—could lead to the tightening of commercial harvest restrictions.

Scientists have attributed the decline in blue crabs not to overfishing, but to high mortality rates among juveniles. While last year’s winter dredge survey measured an unprecedented number of juvenile crabs in the Bay, last summer and fall saw an alarming loss of blue crab habitat and a large influx of red drum, which often feed on young crabs. Young blue crabs are also known to feed on each other when population densities are high.
“It is important to keep these results in perspective,” said Jack Travelstead, commissioner of the Virginia Marine Resources Commission (VMRC), in a news release. “Five years ago this fishery was declared a federal disaster. That is no longer the case: overfishing is no longer occurring, a good fisheries management framework is in place, the stock is healthy and spawning-age females are doing well. If not for the disappointingly small reproductive year class we would have much to celebrate.”
In an effort to make up for this shift in blue crab abundance, Maryland, Virginia and the Potomac River Fisheries Commission (PRFC) are pursuing strategies to establish a 10 percent cut in the commercial harvest of female blue crabs. Both Maryland and the PRFC will consider adjusting or enacting daily bushel limits, which have been put in place in Virginia. Maryland and Virginia will also consider shortening their crab seasons, and it seems likely that Virginia’s winter dredge fishery will remain closed.
The Chesapeake Bay Stock Assessment Committee (CBSAC) will draft their 2013 Blue Crab Advisory Report over the next few weeks.

Close to 15,000 acres of underwater grasses have disappeared from the Chesapeake Bay.
While robust grass beds on the Susquehanna Flats and expanding beds in the James River offer two examples of the Bay’s resilience, an aerial survey conducted by the Virginia Institute of Marine Science (VIMS) showed a 21 percent decline in the Bay’s grasses in 2012. This so-called “alarming” loss—from just over 63,000 acres in 2011 to just over 48,000 in 2012—approaches lows last reported in 1986.
In a report released this week, Chesapeake Bay Program scientists attributed last year's decline in grass beds to warmer-than-normal water temperatures seen in 2010 and strong storms seen in the fall of 2011. The former "cooked" grasses in the Lower Bay, while the latter pushed excess sediment into rivers and streams, clouding the water and creating unfavorable growing conditions for aquatic plants in the Upper and Middle Bay.
These strong storms and episodes of heat stress have occurred alongside a widespread decline in water clarity, said Bob Orth, coordinator of the VIMS Submerged Aquatic Vegetation Survey. While Orth remains "concerned" over the decline in bay grasses, he noted that favorable growing conditions in the future could lead to quick signs of recovery in a species that is fast to respond to water quality changes—both good and bad.
"The best thing we can do [for bay grasses] is to improve water quality," said Lee Karrh, a biologist with the Maryland Department of Natural Resources (DNR) and chair of the Bay Program's Submerged Aquatic Vegetation Workgroup. "If you improve water quality and reduce chronic problems, then the Bay should be able to deal with episodic events easier than it has been able to in the past."
Underwater grasses—also known as submerged aquatic vegetation or SAV—are critical to the Bay ecosystem, offering food and habitat to countless critters while absorbing nutrients, trapping sediment and reducing shoreline erosion. The Bay Program uses underwater grass abundance as an indicator of Bay health, and has this week released a data visualization tool that allows users to track changes in grass abundance over time, as dominant species ebb and flow and grass beds shrink and expand.

Owning and maintaining waterfront property can be an expensive commitment. Residents across the Chesapeake Bay watershed must contend with shoreline erosion and rising sea level, while adapting to environmental regulations that protect water quality. One strategy for tackling all of these issues has gained increasing popularity: living shorelines that not only protect human property, but also utilize and even enhance the Bay’s unique natural habitat.
Scott Hardaway and Karen Duhring are marine scientists and living shoreline experts at the Virginia Institute of Marine Science (VIMS), which sits at the mouth of the York River in Gloucester Point, Va.
Scott Hardaway began working for VIMS in 1979, and is now the director of the Shoreline Studies Program. He is a leading authority on the design and implementation of “headland breakwaters,” a living shoreline technique that creates protected “pocket beaches” like those constructed at VIMS in 2010.
Headland breakwater systems are built using large stone structures called “headlands,” which sit offshore and disrupt the incoming waves that can cause shoreline erosion. Mathematical formulas determine the necessary angle, shape and placement of each headland. Wider gaps between breakwaters create long, narrow pocket beaches, while narrow gaps create wide, circular beaches.
Their wave-blocking action creates a calm, shallow lagoon between the breakwaters, which are connected to shore by a sandbar called a “tombolo.”
Additional sand must be brought in to form the tombolo and stabilize the beach. This raises the cost of these projects, but is critical to the final phase of construction: planting native beach and dune vegetation.
Karen Duhring is an educator and researcher at the VIMS Center for Coastal Resources Management (CCRM), where she helps manage and monitor living shoreline projects.
According to Duhring, on-shore plantings serve key ecological functions that enhance the effectiveness of living shorelines. On sandy beaches, plant roots stabilize loose material and improve water quality, as they filter pollutants from upland runoff.
Living shorelines use native plants—smooth and saltmeadow cordgrass here in the Bay—that have adapted to thrive and reproduce in a specific environment. Once established, cordgrass recruits naturally along the beach, dispersing seeds and rhizomes that spread horizontally beneath the sand to establish new plants in empty areas.
Beach plantings are susceptible to damage from foot traffic, so precautions should be taken to prevent the trampling of plants. Access restrictions allowed for more expensive plantings on the VIMS western shore, while heavy use from research activities limited plantings on the other.
During high tides, organic material washes onto the beach and provides nutrients for the growing plants, which in turn provide habitat and food for native wildlife.
Headland breakwaters themselves also provide habitat for crabs, mollusks and other aquatic species that thrive on underwater reefs. Along the VIMS shoreline, oysters have settled on the granite rocks to form the beginnings of a complex reef community.
According to Hardaway, headland breakwaters are not always the perfect solution for every sandy shoreline. Whenever possible, existing habitat for submerged aquatic vegetation and shellfish should remain undisturbed. While the costly structures do come with some tradeoffs, they also offer invaluable protection for human infrastructure. The once-vulnerable VIMS shoreline, for instance, has withstood Hurricanes Irene and Sandy—thanks to its headland breakwaters.
As the living shorelines at VIMS demonstrate, projects such as these—which successfully address the needs of both humans and nature—are critical to Bay restoration. Through the work of experts like Hardaway and Duhring, these living shorelines continue to serve both practical and educational purposes, teaching the public how we can responsibly manage our natural resources today in order to preserve them long into the future.

After eleven years, $40 million and more than 16,000 linear feet of pipe, West Virginia is set to bring a new wastewater treatment plant online and make huge cuts to the pollution it sends into the Chesapeake Bay.
Under construction in West Virginia’s Eastern Panhandle, the Moorefield Wastewater Treatment Plant will replace four existing plants with one new system, marking a significant milestone in the headwater state’s efforts to curb pollution and improve water quality. Expected to go into operation this fall, the plant will remove 90,000 pounds of nitrogen and 93,000 pounds of phosphorous from West Virginia wastewater each year.
Funded by a range of sources—including the West Virginia Economic Development Authority, the West Virginia Department of Environmental Protection and the U.S. Environmental Protection Agency (EPA)—the new plant is heralded as evidence that thoughtful planning and forward-thinking—especially where pollution regulations are concerned—can help a community move toward conservation and environmental change.
In the 1990s, the hundreds of wastewater treatment plants that are located across the watershed could be blamed for more than a quarter of the nutrient pollution entering the Bay, as the plants pumped water laden with nitrogen and phosphorous into local rivers and streams. Such an excess of nutrients can fuel the growth of algae blooms that block sunlight from reaching underwater grasses and, during decomposition, rob the water of the oxygen that aquatic species need to survive.
But in the last decade, technological upgrades to wastewater treatment plants have surged, and the pollution cuts that result mean these plants now contribute less than 20 percent of the nutrients still entering the Bay.
According to Rich Batiuk, Associate Director for Science with the EPA, the uptick in upgrades can be attributed to a number of factors.
“Wastewater treatment plants have always been regulated,” Batiuk said. “But [until the last decade], there wasn’t the science or the political will or the … water quality standards that could drive the higher levels of wastewater treatment that result in lower levels of nitrogen and phosphorous flowing into the watershed.”
As the science behind wastewater engineering has improved and the incentives for implementing upgrades have grown, more plants have begun to make changes. Some implement a “zero discharge” plan, using nutrient-rich effluent to feed agricultural crops rather than excess algae. Others—like the Moorefield plant—expose wastewater to nutrient-hungry microbes that feed on nitrogen and phosphorous; the resulting sludge, modified without the addition of chemicals, can be turned into compost rather than fodder for the local landfill.
Such modern upgrades to otherwise aging infrastructure have been celebrated as a boon for local communities and the wider watershed. While the Moorefield plant will, in the end, curb pollution into the Bay, it will first curb pollution in the South Branch of the Potomac River, into which it sends its effluent.
"The South Branch of the Potomac is a unique place,” Batiuk said. “People fish there, they swim there. This new plant helps more than the Chesapeake Bay.”
And Moorefield residents—including the Town of Moorefield Public Works Director Lucas Gagnon—plan to witness this local change firsthand.
“The residents in this area are aware of the Chesapeake Bay and its needed [nutrient] reductions,” Gagnon said. “But the biggest benefit for the local folks will be the reduction of nutrients in local waterways.”
“There are many people that fish and boat the South Branch,” Gagnon continued. “When this plant goes online, the water quality will be greatly enhanced, and they will have a much cleaner, better river to enjoy.”
In rural West Virginia, a fisherman casts his bright green line into a mountain stream. The stream is clear, the fish are biting and it takes just minutes to make a catch.
Dustin Wichterman, Potomac Headwaters Project Coordinator with Trout Unlimited, dips his net into the water and reveals a 10-inch brook trout. Its olive green body is flecked with red and gold, and its mere presence here is a welcome sign of health for the Pendleton County waterway.
Native to the headwaters of the Chesapeake Bay, the eastern brook trout is a sensitive species that needs cold, clean water to survive. But as regional water quality has declined, so, too, have brook trout populations, leading to lost revenue and diminished fishing opportunities for headwater states.
Brook trout play a critical role in the watershed: they are an important part of the region’s natural heritage, a driver of economic growth and an indicator of environmental health. For these reasons, brook trout restoration was a listed outcome in the federal Strategy for Protecting and Restoring the Bay Watershed. And for the past two years, brook trout conservation has been a top goal for the Chesapeake Bay Program.
Through the Bay Program’s Habitat Goal Implementation Team, whose members work to protect and restore wetlands, woods and other habitats across the watershed, brook trout have benefited from stream restoration, fish passage renewal and tree plantings.
As odd as it might seem, the health of a fish depends not just on the health of the creek, stream or river that it calls home; it is also tied to the health of the surrounding land. And poor land management, increasing development and expanding urbanization have been cited as leading factors in brook trout decline.
“This fish is a living symbol of how actions on land affect the health of our local waterways,” said team coordinator Jennifer Greiner.
The removal of streamside trees, for instance, is a common consequence of agricultural or residential development, as seedlings are trampled by grazing cattle or trees are felled for suburban growth. But a missing forest buffer means bad news for brook trout when stream banks erode, excess sediment ruins spawning beds and an absence of shade pushes water temperatures into a range that brook trout cannot withstand.
When, on the other hand, trees and shrubs are allowed to grow along waterways, their runoff-trapping roots keep the water clean and their shade-producing leaves keep the water cold.
So Greiner and her fellow team members have worked to bring brook trout into the land-use discussion, pushing the latest brook trout distribution data out to doers and decision-makers in the watershed. Because when land managers know where brook trout are, they are more likely to take the fish into account in land-use decisions.
Land trusts in headwater states have also found that brook trout can push private landowners to conserve, and Goal Implementation Team partners—the U.S. Fish and Wildlife Service, the Natural Resources Conservation Service, the National Fish and Wildlife Foundation and the Eastern Brook Trout Joint Venture Partnership among them—are using the iconic fish to promote on-the-ground restoration of riparian forest buffers.
Whether a farmer installs a fence that keeps livestock out of local rivers or a landowner decides to plant a series of streamside trees, education and engagement are critical to conservation.
“By becoming educated and engaged, landowners are able to protect the streams on their land for future generations,” Greiner said. “By protecting and restoring stream habitat, the brook trout, along with other species, are also protected for future generations to enjoy.”
In Virginia, there is a local legend that explains how the Cowpasture River and its surrounding streams were named: A group of Native Americans stole a herd of cattle from a settler and headed west. The calves tired first, and were left behind at the river now known as the Calfpasture. The cows were able to make it a bit farther, to Cowpasture. And the bulls, with greater strength and stamina, made it to Bullpasture.

The tale might not be true, but the names still fit. All three rivers are bordered by pastureland and meadows, a perfect habitat for indigo buntings, northern bobwhite and other open-country birds, as well as local livestock.
The nearby George Washington and Jefferson National Forests and state natural lands offer opportunities for outdoor enthusiasts to experience this rustic, rural watershed.
If you would rather explore “underground,” be sure to check out the region’s caves and sinkholes. During periods of extended drought, the Cowpasture River dries up and flows only beneath the ground, through the limestone caves.

In Jefferson County, W.Va., shaded streams trickle down the Blue Ridge Mountains into what will become the Potomac or Shenandoah rivers. The ridge is named “blue” for its characteristic purple-blue haze. No, this isn’t some kind of rural smog, but isoprene, which the trees on the mountain release into the atmosphere.

Despite the pristine scenery found in this part of the Chesapeake Bay watershed, a visit to Jefferson County on a rainy day can expose a darker side. Thanks to aging infrastructure, the county has faced flooded roads and a river that carries an unknown amount of pollutants.
Residents knew they had to take action to ensure their mountain’s health. So, the Blue Ridge Watershed Coalition was born. And in just over 18 months, the non-profit organization has arranged stream cleanups, showcased stormwater management practices and monitored water quality in a stretch of the Shenandoah River.
Why monitor water quality?
To monitor water quality, biologists take water samples from a stream or river and send them into a lab. There, the amount of pollutants in the water is measured. Monitoring a series of sites in a single waterway can tell us where these pollutants might be coming from.
Before the Blue Ridge Watershed Coalition was formed, monitoring in the Shenandoah River was completed by a single Shenandoah University professor. Now, the college will train coalition volunteers to take water samples, as the coalition works to determine pollution sources and track the river’s long-term health.
“Our friends and neighbors on the mountain had very adamantly voiced that they wanted real facts as to what is in our lovely Shenandoah River,” explained Ronda Lehman, Blue Ridge Watershed Coalition Chair.
“We hope our river monitoring will help delineate whether our issues are born from our county’s farms, septic tanks or stormwater runoff, or a combination,” said Ronda.
Curbing runoff, preventing floods
Close to 17,000 commuters leave Jefferson County, W.Va., for Washington, D.C., each morning, and many of them travel on Route 9. But this road often floods, as it collects stormwater runoff from surrounding properties.
The Blue Ridge Watershed Coalition hopes to curb the amount of runoff coming from one of these properties—an old stone church now called the Mountain Community Center.
“A little calculating showed us that there are 1,400 gallons of water that run off the roof of the church during average rain events,” said Ronda.
The coalition will divert rainwater from the roof of the building into rain barrels and cisterns and curb the flow of sediment and stormwater with a filter installed at the end of the driveway.
“Incorporating different methods of mitigating that flow of water would give us an opportunity to showcase different practices for our neighbors to incorporate onto their own properties,” Ronda said.
If water quality monitoring and stormwater management seem too “scientific” for your tastes, then an old-fashioned trash cleanup could be for you! The Blue Ridge Watershed Coalition held its second annual cleanup in July.
The cleanup area is popular among the public, but has a history of being dirty.
The coalition hopes to amend this littering problem. “We will be purchasing banners to be placed at the busy ‘put ins’…to remind patrons to take their trash with them," said Ronda.
True to its name, West Virginia’s “Lost River” disappears.
Lost River begins in West Virginia’s eastern panhandle. But just a few miles downstream, it flows into a series of caves and is carried underground. Known locally as “the Sinks,” these caves shelter the river until it reaches Wardensville, where it emerges under a different name: the Cacapon.

American eel numbers are up in the headwater streams of Shenandoah National Park, following the 2004 removal of a large downstream dam.
Significant increases in upstream American eel populations began two years after the Rappahannock River's Embrey Dam was removed and have continued nearly every year since, according to a report released last week by the U.S. Geological Survey (USGS), U.S. Fish and Wildlife Service (USFWS) and National Park Service (NPS) researchers.

Dams can act as travel barriers to American eels, which undertake long-distance migrations from their ocean spawning grounds to freshwater streams along the Atlantic coast. While American eels can surpass substantial natural barriers--like the rapids of the Potomac River's Great Falls, for instance--dams pose a more difficult obstacle and have contributed to the widespread decline in American eel populations. Dam removal, therefore, could have long-term benefits for eel conservation.
"Our study shows that the benefits of dam removal can extend far upstream," said USGS biologist Nathanial Hitt. "American eels have been in decline for decades and so we're delighted to see them begin to return in abundance to their native streams."
Embrey Dam, which once provided hydroelectric power to Fredericksburg, Va., was breached in 2004 following years of work by nonprofit organizations and city, state and federal government agencies. Its removal was intended to benefit more than the American eel, however, as dams can impact a number of fish that must migrate up rivers to spawn.
"Shad, herring and striped bass are also using reopened habitat on the Rappahannock River," said Alan Weaver, fish passage coordinator for the Virginia Department of Game and Inland Fisheries. "It's exciting to see a growing number of species benefiting from dam removal in Virginia."

In the 1930s, Smithsonian botanist Harry A. Allard walked 3,000 miles and collected 15,000 plant specimens in the Bull Run Mountains of Virginia's Eastern Piedmont region.
Eighty years later, Smithsonian scientists collect beetle specimens in the same mountains. A few miles away, volunteer naturalists explain to children and adults why beetles are central to all life; different beetle species pollinate plants (helps plants reproduce), and assist with decomposition (eats dead organisms).

Such a combination of research and education is rare, says Michael Kieffer, Executive Director of the Bull Run Mountains Conservancy, a nonprofit headquartered in the southern 800 acres of the 2,500 acre Bull Run Mountains Natural Area Preserve, about 15 miles from Manassas, Middleburg, and Warrenton, Virginia.
"We have the unique opportunity to conduct both youth and adult education programs and to tie those programs to research on the mountains," says Michael.
While the Bull Run Mountains Conservancy leads research, stewardship, and education programs in the natural area, the land itself is owned by the Virginia Outdoors Foundation.
With plenty of places to search for the region's rare plants and insects, the conservancy's nine miles of trails see 10,000 visitors per year.
"It is wonderful to have public access to this state natural area, but people management is always an issue," states Michael.
Stewardship goes hand in hand with the conservancy's education programs.

Programs such as "nature preschool," "herpetology camp," and even teachers' workshops, allow participants to study the ecosystem through experience, just the way Allard did eighty years ago.
When asked to elaborate on the conservancy's immersion education philosophy, Michael explained, "Just keep them outside. They need to be outside. Yes, it’s based on the research, but no we don’t have camp counselors. It's about getting kids outside with other kids. This is vital to your life."
But as any parent knows, kids learn by example. If adults are not prone to spend time outdoors, neither will their children.
"At BRMC our education programs are equally weighed between adults and children. If adults do not learn alongside their children, then the child’s experience on the mountains is diminished.”
The Bull Run Mountains Conservancy's summer camps begin in June. But nature lovers of all ages are invited to join their naturalist-led walks, trail clean up days, rattle snake surveys, and watershed workshops throughout the year.

The area is one of the most important avian migration funnels in the country, meaning it provides vital stopover habitat for birds and butterflies migrating south for the winter and north for the summer. Return in the winter for a trip to Fisherman Island, a remote island home to sensitive bird species and untouched shoreline.
4. Nassawango Creek Preserve of the Nature Conservancy and Furnace Town (Snow Hill, Md.)
Just south of Salisbury, Maryland, one of the northernmost stands of bald cypress trees leak tannins into the Nassawango Creek, giving this pristine Chesapeake Bay tributary a deceptive tea-like color. Bald cypress trees grow completely in the water, and are most abundant in swamps in the deep southeast United States. Visitors to the 15,000-acre Nassawango Creek Preserve can paddle among these green giants or explore upland forest habitat on the preserve's many trails. Expect to see rare plants like indian pipe and pink lady slipper, and migratory birds such as scarlet tanagers and prothonotary warblers.
Along the edge of the preserve, hidden in the Pocomoke State Forest, a brick structure stands tall among the trees. It is the remnants of an iron furnace that at one time attracted hundreds of people – miners, firemen, bargemen and sawyers – to the area. From 1831 to 1850, village residents gathered iron ore from the bogs surrounding Nassawango Creek and loaded iron bars onto barges that were floated down the creek to the Pocomoke River and the Chesapeake Bay. Today, you can get a glimpse of what life was like in the 1830s mining village by visiting the Living Heritage Museum.
5. Pickering Creek Audubon Center (Easton, Md.)

If you're driving to Ocean City or Assateague Island, you'll likely pass hundreds of cornfields, strawberry fields and trucks full of chickens. Farming is a significant part of the heritage of Maryland's Eastern Shore, but the agricultural industry is often blamed for polluting the Chesapeake Bay.
At Pickering Creek Audubon Center in Easton, 270 acres are farmed according to "best management practices" that reduce the amount of animal bacteria, chemicals and pesticides that end up in the bay. Visitors can learn the past and future of farming in the region, or hike through hardwood forests, fresh and brackish marshes, meadows and wetlands. A Children's Imagination Garden will let your little ones connect to nature, and a display of live reptiles allows them to get up close and personal with our scaly friends!
6. Trap Pond State Park (Laurel, Del.)
Trap Pond was created in the late 1700s to power a sawmill during the harvesting of bald cypress trees from these southwestern Delaware freshwater wetlands. Fortunately, not all of the trees were harvested, and today, Trap Pond provides a home for the northernmost stand of bald cypress trees in the United States. The thick bald cypress marsh envelops visitors in a blanket of shade, making this park the perfect destination for a hot summer day.
Within the park, Trussum Pond is the best place to view the largest of these trees. Biking, camping, boating and disc golf are just some of the recreational opportunities available at the 2,700 acre park.
7. James Branch Nature Preserve and Water Trail (Laurel, Del.)
Unlike Trap Pond, which, as a state park, exists primarily for recreational purposes, James Branch Nature Preserve's first priority is protecting and enhancing a delicate ecosystem for future generations. As the largest of the state's nature preserves, James Branch's 685 acres are mostly composed of bald cypress trees – the oldest-growth in the state! Visitors can canoe and kayak the James Branch Water Trail. Since there is the chance of encountering downed trees, low-hanging branches, and floating and submerged logs, the trail is only recommended for intermediate to advanced paddlers.
8. Adkins Arboretum (Ridgely, Md.)
For some people, it's difficult to imagine your garden untouched by invasive, exotic weeds aggressively overtaking native vegetation. But at Adkins Arboretum, you can explore 400 acres of native plant gardens and wildflower meadows. Adkins is the only public garden or arboretum that focuses solely on plants native to the mid-Atlantic coastal plain. Located at the intersection of the piedmont and coastal plain, and the junction of the north and south, Adkins supports more than 600 species of native shrubs, trees, wildflowers and grasses. Visitors can understand nature through the lens of art and history; an ongoing art exhibit features natural themes by regional artists, and Adkins describes nature's relationship to the Underground Railroad throughout the region. Before you visit, be sure you check the arboretum’s list of programs and guided walks.
When Robbi Savage’s 10-year-old grandson Seth saw a car battery submerged in the Rivanna River near Charlottesville, Virginia, he knew enough not to pick it up. Instead, he asked his dad for help, and with more frustration than curiosity, exclaimed to Robbi, “What are these people thinking, grandma?!”
“Even a 10-year-old knows that throwing car parts into the river is dangerous,” says Robbi, executive director of the Rivanna Conservation Society (RCS), a non-profit watershed group based out of Charlottesville. “And yet some folks still think of a river as a trash dump.”
(Image courtesy Rivanna Conservation Society)
Robbi and RCS’s volunteers are dedicated to cleaning up the Rivanna, a 42-mile-long James River tributary that flows from the Blue Ridge Mountains through the foothills and Piedmont region of central Virginia. It was the first river in Virginia to be designated a “Scenic River.” Although the Rivanna may be “scenic,” RCS understands that maintaining its beauty and enhancing its degrading health requires citizen participation, education and local government involvement.
“One would think that being at the headwaters, we would have close to pristine waterways, but such is not the case,” Robbi explains. “We certainly have our challenges.”
One of the Rivanna’s biggest problems is stream bank erosion, which pollutes the water with too much sediment. Bacteria from pet waste and agricultural manure also threaten swimming areas and drinking water resources; this occurs when residents don’t pick up after their pets, or when farmers allow cattle to enter streams.
RCS’s education and outreach programs have been building awareness of these issues since the group was founded in 1990. But RCS doesn’t forget to have some fun along the way. River paddles, survival workshops and geocaching are just a few outdoor activities the group sponsors.

When Robbi moved from Washington to central Virginia in 2006, she brought with her an environmental initiative she conceived while working on national water policy in Washington. The international citizen-led water quality monitoring effort World Water Monitoring Day involved 340,000 people in 77 countries in 2011. When Robbi left the Hill to become RCS’s executive director, she created a local version of the program, “Water Health for the Commonwealth.”
The program allows middle and high schools along the Rivanna and James Rivers to monitor their local water quality and connect with one another to share their results. RCS is in the process of extending this hands-on-learning opportunity to all schools along the James, from the Rivanna watershed to the Chesapeake Bay.
This “in the river” approach not only educates, but creates an appreciation for the “River Anna,” named after Queen Anne of England.
In addition to education initiatives, recreational opportunities such as river paddles and geocaching (a treasure hunt-like activity) allow area residents of all ages to get outside and appreciate the scenic Rivanna.
“Recreation is an important part of what this river is used for,” explains Robbi. “But the more people you bring to the river, which is of course part of our mission, the more attention needs to be paid to keeping it clean. We have a beautiful river here, so people want to paddle, and they want to be on the water.”
For Robbi, RCS represents community collaboration.
Robbi gained experience in environmental issues at the national and international level in her 35 years of working for EPA Office of Water, the League of Women Voters, and the State and Interstate Water Pollution Control Administrators (now Association of Clean Water Administrators).
But when she moved to central Virginia and became involved with RCS, she experienced the challenges and successes of converting Washington’s laws and regulations into local action.
“When you work in Washington, you may come to believe that it is the center of the universe,” explains Robbi. “But when you move to a location like Charlottesville and see what it takes in terms of voter support, local government coordination, and funding decisions, it’s eye-opening. We all know that water quality is important and essential to all living things, but when you actually see the demands for scarce community resources to play out, especially in this zero-based budget economy, you understand that tough choices are being made.”
Although coordinating community leaders, landowners, citizen volunteers, lawmakers and environmentalists is no easy task, Robbi describes it as rewarding. “I would never have said this as a young pup in DC, but I think the real action is at the local level. We are turning words into action.”

The Chesapeake Bay’s blue crab population increased 66 percent in 2012 to its highest level since 1993, according to the annual blue crab winter dredge survey conducted by Maryland and Virginia.
The enormous increase was fueled by a “baby boom” – an almost tripling of the juvenile crab population, from 207 million last year to 587 million. This figure smashed the old record of 512 million juvenile crabs set in 1993.
Overall, the Bay’s crab population has risen to 764 million, more than triple the record low of 249 million set in 2007. That deep decline set in motion four years of concentrated efforts to rebuild the stock.
“Just a few short years ago, the future did not look bright for our blue crab population,” said Maryland Gov. Martin O’Malley. “Our female crabs were being overfished, and our fishery was at risk of complete collapse. We teamed up with our neighbors in Virginia and at the Potomac River Fisheries Commission to make the tough choices, guided by science, to reverse that population decline.”
Bay-wide, the crab harvest has increased substantially since 2008, when 43 million pounds were caught. In 2011, an estimated 67.3 million pounds of crabs were harvested from the Bay.
Not all news from the survey was bright: the number of spawning-age females dropped by roughly 50 percent to 97 million. However, this figure is still above the health threshold. Maryland and Virginia will work together to produce a management strategy to avert another stock decline for this segment of the crab population.
Visit the Maryland Department of Natural Resources’ website for more information about the winter dredge survey and the 2012 blue crab figures.
Ask any local about the 12 odd-shaped “Lone Star Lakes” in southern tidewater Virginia, and you’re bound to hear some fish stories about crappies, bluegill and catfish. Although these lakes were originally dug out to excavate marl (minerals such as clay and limestone), they now provide abundant fishing for enthusiasts, as well as drinking water for the nearby city of Suffolk.
Crane Lake is rumored to be the most fruitful of the Lone star Lakes, perhaps because it’s connected to Chuckatuck Creek, a 13-mile-long stream that parallels the Nansemond River before flowing into the James River. During high tide, salt water spills into the lake, sometimes sending croaker, big stripers and flounder into the hands of lucky fisherman.
Native Americans also fished in these waters; Chuckatuck Creek was a valuable resource for the Nansemond tribe. But when Englishmen arrived in the early 1600s, they robbed the tribe’s corn and burned their homes and canoes. This was the beginning of hostility between the communities, and resulted in the Nansemond tribe losing its last reservation lands in the late 1700s. Today, most Nansemond Indians still live in the Suffolk/Chesapeake area.
In the first half of the twentieth century, Chuckatuck Creek was packed with boats. Watermen made a living from harvesting oysters, fish and crabs, and taught their sons their craft for generations. Families visited one another via watercraft, depending on each other when there was little to catch.
Today, a decline in oyster populations has left few generational watermen on the Chuckatuck. Nevertheless, the creekside villages of Crittenden, Eclipse and Hobson still possess a small-town ambience, with close-knit residents and colorful local folklore.

Six of the seven Chesapeake Bay jurisdictions – Delaware, Maryland, Pennsylvania, Virginia, West Virginia and the District of Columbia – have submitted their final cleanup plans as part of the Chesapeake Bay TMDL, a “pollution diet” that aims to put in place all restoration measures needed for a clean Bay by 2025.
The final cleanup plans, officially known as Phase 2 Watershed Implementation Plans (WIPs), were submitted to the U.S. Environmental Protection Agency last Friday. New York submitted its draft plan, and is working with the EPA to finalize that plan.
The cleanup plans were developed by each individual state and the District, working closely with counties, municipalities and other local partners. The cleanup plans identify specific restoration measures each jurisdiction will take to reduce nitrogen, phosphorus and sediment pollution to the Bay and its local rivers.
According to the guidelines set in the TMDL, at least 60 percent of necessary pollution reductions must be achieved by 2017. Chesapeake Bay Program partners have committed to putting all needed pollution control measures in place no later than 2025.
Visit the EPA’s Chesapeake Bay TMDL website to review and learn more about the cleanup plans.
Like many buildings in Northern Virginia, Fairfax County’s Herrity Building is surrounded by traffic and occupied by government workers. But Herrity also sports a landscaped pond that’s not just a parking lot decoration. It’s the headwaters of Difficult Run, a Potomac River tributary that winds through development-burdened Fairfax County before ending near Great Falls Park, where it’s enveloped in lush vegetation, dotted with boulders and surrounded by scenery that seems straight out of a time period from long ago.
(Image courtesy gawnesco/Flickr)
Difficult Run’s health fluctuates dramatically throughout its 15-mile run. In cities like Reston and Vienna, unsustainable land use practices have led to eroding stream banks and poor water quality. At 58 square miles wide, Difficult Run’s watershed is the largest in Fairfax County, which means the waterway is affected by development and pollution that happens very far away from its banks.
Luckily, in other places, forest buffers hug the stream’s edges, helping to keep soil in place, provide wildlife habitat, and shade and cool the water. These forested areas have become a favorite of locals who enjoy walking through the woods.
For an excellent weekend hike or bike ride, follow Difficult Run on a secluded 12-mile trail from Glade Drive in Reston to Great Falls Park. Will Difficult Run be difficult? Rumor has it that the trail is perfect for intermediate bikers and beginner hikers.
Perhaps the “difficulty” of Difficult Run lies in reversing the effects of development that has led to pollution in many parts of the stream. Fortunately, Fairfax County and others have begun work to restore this important local waterway. In 2008, the Herrity Building installed a green roof atop its parking garage. This colorful garden of native plants prevents stormwater runoff from carrying oil, trash, auto exhaust and other pollutants from the parking lot into Difficult Run.

Along Difficult Run’s banks, the Virginia Department of Forestry has conducted streamside restoration projects and an outreach effort that now serves as a model for other local stream restoration initiatives in the state.
Fewer acres of bay grasses grew in the shallows of the Chesapeake Bay and its tidal rivers in 2011, according to scientists with the Chesapeake Bay Program. Bay grass acreage fell to an estimated 63,074 acres in 2011, down from 79,664 acres in 2010. This is the lowest Bay-wide acreage measured since 2006.
Because of heavy rainstorms that led to cloudy, muddy conditions that blocked monitoring efforts, only 57,956 acres of bay grasses were actually mapped in 2011. However, scientists believe about 5,119 acres of bay grasses may have been present during the height of the growing season, leading to the final estimated Bay-wide figure of 63,074 acres.
Bay grasses – also known as submerged aquatic vegetation or SAV – are a critical part of the Bay ecosystem. These underwater meadows provide fish, crabs and other aquatic life with food and habitat, absorb nutrients, trap sediment, reduce erosion, and add oxygen to the water. Bay grasses are also an excellent measure of the Bay's overall condition because their health is closely linked with the Bay’s health.
“2011 was the year that bucked two trends we’ve seen over the last decade,” said Lee Karrh, chair of the Bay Program’s Submerged Aquatic Vegetation (SAV) Workgroup. “The Upper Bay had major decreases after years of increasing or sustained high acreages. On the other hand, the brackish parts of the Middle Bay witnessed dramatic increases in 2011, after prolonged decreases since the turn of the century.”
Experts agree that extreme weather conditions in 2010 and 2011 led to the substantial decrease in bay grasses. According to Bob Orth, scientist with the Virginia Institute of Marine Science (VIMS) and coordinator of the annual bay grass survey:
In the upper Bay (from the mouth of the Susquehanna River to the Chesapeake Bay Bridge), bay grasses covered approximately 13,287 acres, down from 21,353 acres in 2010. This is most likely an underestimate because scientists did not monitor the area until November, once muddy conditions improved but well past the end of the growing season. One bright spot in the upper Bay was the more than doubling of bay grass acreage in the Chester River and near Eastern Neck.
In the middle Bay (from the Bay Bridge to Pocomoke Sound and the Potomac River), bay grasses decreased 4 percent to an estimated 34,142 acres, down from 35,446 acres in 2010. (Only 29,023 acres were mapped, but scientists estimate that an additional 5,119 acres may have been present.) Large eelgrass losses were observed in Tangier Sound. These were offset by widgeon grass gains in many areas, including Eastern Bay and the Choptank River.
In the lower Bay (south of Pocomoke Sound and the Potomac River), bay grasses covered 15,645 acres, down 32 percent from 22,685 acres in 2010. Hot summer temperatures in 2010 led to this significant drop in acreage, which offset any gains that followed in 2011. Eelgrass in many parts of the lower Bay had been recovering from similar heat-related losses that took place in 2005.
Despite Bay-wide losses, there were a few bits of good news for bay grasses last year. The huge, dense bed on the Susquehanna Flats – which has increased threefold in size over the past 20 years – survived the late summer tropical storms, showing how resilient healthy bay grass beds can be to natural disturbances. Also, scientists recorded the first-ever bay grass bed in the mainstem James River since the area was first surveyed in 1998.
Annual bay grass acreage is estimated through an aerial survey, which is conducted from late spring to early autumn. Residents can do their part to help restore bay grasses by not fertilizing in the spring and planting more plants to reduce polluted runoff from backyards.
For detailed information about 2011 bay grasses acreage, including aerial photos and year-to-year comparisons, visit VIMS' SAV blog. For more information about the aerial survey and bay grass monitoring efforts, visit VIMS’ SAV website.
Virginia added approximately 840 miles of streams and 2 square miles of estuaries to its list of impaired waters in 2012, according to the state’s latest water quality report, released by the Virginia Department of Environmental Quality (DEQ). Virginia must develop more than 1,000 cleanup plans to restore the health of these and other polluted waterways.
About 260 miles of streams were removed from the list after achieving water quality standards, while another 230 stream miles were partially delisted.
In total, about 13,140 miles of streams and 2,130 square miles of estuaries are listed as “impaired,” which means they do not support aquatic life, fish and shellfish consumption, swimming, wildlife and/or public water supplies. Approximately 5,350 miles of streams and 140 square miles of estuaries are considered in good health.
Every two years, Virginia monitors about one-third of its watersheds on a rotating basis. The state completes a full monitoring cycle every six years. Since 2002, Virginia DEQ has assessed 98 percent of the state’s watersheds.
The full water quality report is available on Virginia DEQ’s website. The public is invited to comment on the report until April 27. Virginia DEQ will host a webinar summarizing the report’s results on April 9 from 10 to noon.
The return of ospreys whistling through the air is a surefire sign of spring in the Chesapeake Bay region. But even those who can’t make it to the Bay’s shores can enjoy a glimpse of this remarkable raptor through online osprey cams at Blackwater National Wildlife Refuge and the Virginia Institute of Marine Science (VIMS).
The Blackwater osprey cam is located on an osprey platform in a marsh on the wildlife refuge’s grounds in Dorchester County, Maryland. The VIMS osprey cam is trained on a nest at the top of a water tower on the school’s campus in Gloucester Point, Virginia.
The two osprey cams provide real-time views of osprey pairs during their annual nesting and breeding season in the Chesapeake region. Both osprey cams include a blog, where you can view photos and journal entries chronicling the lives and milestones of each osprey family.
Want to learn more about ospreys? Visit our osprey page in our Chesapeake Bay Field Guide.
Every Sunday morning at 8, a handful of bird enthusiasts flock to Dyke Marsh, the only freshwater marsh along the upper tidal Potomac River. The Dyke Marsh Wildlife Preserve, located south of Alexandria, Va., is home to almost 300 species of birds. The marsh is classified as a “globally rare” habitat, one that’s particularly unique in this dense, urban area just outside the nation’s capital.
(Image courtesy of Friends of Dyke Marsh)
Since 1975, the nonprofit volunteer group Friends of Dyke Marsh (FODM) has helped preserve, restore and celebrate this rare ecosystem. In addition to arranging weekly bird watching trips, FODM sponsors scientific surveys, leads school groups, removes invasive plants, organizes cleanups and builds public appreciation for the marsh.
FODM supports scientific surveys that illustrate the marsh’s irreplaceable habitat. Freshwater tidal marshes are flooded with fresh water with each incoming high tide, and include a variety of rare emergent grasses and sedges rather than shrubs.
“Dyke Marsh is a remnant of the extensive tidal wetlands that used to line the Potomac River,” explains FODM president Glenda Booth. “It provides buffering during storms. It absorbs flood waters. It’s a nursery for fish. It’s a rich biodiverse area in a large metropolitan area. We think it’s important to preserve what little is left.”
With the support of FODM, a Virginia Natural Heritage Program employee completed a survey of dragonflies and damselflies on the preserve in spring 2011. In addition, members conduct a breeding bird survey every spring. Last year, FODM recorded 78 species. The highlight? A confirmed breeding eastern screech-owl, the first documented in 20 years.

“Our biggest challenge is to stop that erosion and restore Dyke Marsh,” says Booth.
Dyke Marsh was already destabilized in 1959, when Congress added it to the U.S. National Park system. USGS scientists largely attributed this to human impacts: sand and gravel mining that gouged out substantial parts of the marsh and removed a promontory that protected the wetland from storms, leaving Dyke Marsh exposed and vulnerable.
FODM works with the National Park Service to enhance wetland habitat and slow erosion of the marsh’s shoreline.
Educating neighbors about their connection to Dyke Marsh and fostering appreciation of this scenic area are also essential components of FODM’s preservation goals.

Like most other parts of the Chesapeake Bay watershed, invasive plants are a problem in Dyke Marsh. “A lot of people plant things that are aggressive and not native, and these plants end up in the marsh.” And pollution that flows into streams throughout Fairfax County eventually empties into Dyke Marsh, threatening its wildlife and habitat.
Preserving Dyke Marsh is a goal that extends beyond the marsh itself, according to Booth. “We have to make sure that activities on our boundaries are compatible with preservation goals.” That means advocating for regulations that prohibit jet skiing, which disturbs the marsh’s nesting birds in spring.
Visit FODM’s website to learn more about upcoming outreach and educational opportunities and to find out other ways you can enjoy Dyke Marsh.
Fisheries scientists with the Chesapeake Bay Program will develop a Chesapeake Bay-wide management plan for blue and flathead catfish, two invasive fish species that pose a significant threat to the health of rivers in Virginia, Maryland and Pennsylvania.
(Image courtesy USFWS Headquarters/Flickr)
Invasive species are animals and plants that are not native to their current habitat and harm the ecosystem they invade. Invasive species are able to thrive in new areas because they lack predators, diseases and other natural controls that keep them in check in their native environment.
Although they are valuable recreational species, blue and flathead catfish are harmful to the Bay ecosystem for several reasons. They grow to enormous sizes, have massive appetites, reproduce rapidly and live for many years. As top-level predators in the Bay food web, blue and flathead catfish prey upon important native species such as American shad and blueback herring.
Both catfish species have been present in Virginia rivers since the 1960s. In recent years, anglers have caught these fish in the Potomac and Susquehanna rivers, as well as the upper Chesapeake Bay. The spread may be due to people moving fish from one river to another, even though this is illegal in Maryland and Virginia.
Scientists will consider a variety of actions to control and lessen the harmful effects of these invasive catfish. For more information, read the Bay Program fisheries team’s Invasive Catfish Policy Adoption Statement.
The Bay Program fisheries team includes experts from the Virginia Department of Game and Inland Fisheries, Virginia Marine Resources Commission, Potomac River Fisheries Commission, D.C. Department of the Environment, Maryland Department of Natural Resources, Atlantic States Marine Fisheries Commission and the National Oceanic and Atmospheric Administration.
From old box springs to blown-out tires, we’ve all had “problem waste” that’s too big and bulky for curbside disposal. The next option is usually to borrow a friends’ pickup truck and drop off your awkward, heavy or disgusting objects at the local dump. But if you live in Fairfax County, Va., there are only two places where you can legally dump your trash (4618 West Ox Road, Fairfax, and 9850 Furnace Road, Lorton).
(Image courtesy Let’s Do It, Virginia)
Maybe it’s the inconvenience of driving across the county to get rid of “problem waste,” or maybe it’s the fee residents must pay to properly dispose of their trash ($6 for five 32-gallon bags, $9 for six to 10). Whatever the case, some residents are illegally dumping their unwanted appliances, shoes, baby clothes and car parts along Accotink Creek, a 25-mile-long Potomac River tributary.
Friends of Accotink Creek is a Fairfax-based volunteer group dedicated to battling illegal dumping. On weekends from March 31 to April 28, Friends of Accotink Creek will be cleaning different sections of the creek as a part of the greater Potomac Watershed Cleanup. The cleanups are much needed: since April 2007, there have been 166 reported illegal dumping acts in the county, and countless others remain unreported. Students, community members, religious organizations, neighbors and nature lovers will come together to drag abandoned dryers up hills and pull embedded tires out of streams. Interested in helping out? Be sure to bring your muscles!
Who knows – someone else’s trash may become your treasure. Volunteer Olivier Giron is building his master’s thesis around taking photographs of the trash – not because he thinks it’s beautiful, but because he believes the dismal juxtaposition of greenery and rusted metal will help influence people’s dumping behaviors. His website, Let’s Do It, Virginia, shows photos of the discarded trash and encourages other organizations to get involved in World Clean Up 2012.

Illegal dumping is one of the largest problems that Friends of Accotink Creek tackles. But the group also has its hands in a variety of environmental projects to restore and protect Accotink Creek.
Klub Kudzu is Friends of Accotink Creek’s invasive weed removal project. On Wednesdays, volunteers help remove kudzu, a climbing and coiling vine native to Asia. Kudzu has no predators to control its spread in the United States; as a result, it grows quickly, climbing over trees and shrubs and killing them by blocking out sunlight. If you’re free, join Friends of Accotink Creek to help save the creek’s native plants from this invader!
Volunteers monitor Accotink Creek for macroinvertebrates: worms, clams and other small creatures that live at the bottom of streams. Macroinvertebrate populations indicate the health of streams like Accotink Creek. Join other critter counters at Lake Accotink Park on the second Saturday of March, June, September and December.

Friends of Accotink Creek relies on volunteers like you to keep these restoration activities running. So contact the organization today and volunteer your time to a good cause. You can also stay in touch with Friends of Accotink Creek on Facebook.
The Elizabeth River, a 6-mile-long tributary of the James River in southeastern Virginia, was named after Princess Elizabeth Stuart. She was the daughter of England's King James I, Jamestown's namesake.
Today, Princess Elizabeth is still around – yes, you heard us right! She often speaks to students in the Hampton Roads community about how people can help restore her river to the way it looked when Captain John Smith first explored it in 1607. The princess's public speaking appointments are arranged by the Elizabeth River Project, a non-profit committed to improving the health of the Elizabeth River through restoration efforts and education programs that celebrate the river's history and natural resources.

Royal advocacy is one of many ways the Elizabeth River Project is achieving its goal of making the river safe for swimming and eating oysters by 2020. Here are some of the Elizabeth River Project's other inspiring programs.
You may have heard that saying, "Those that can't do, teach." But like the many excellent teachers out there, the Elizabeth River Project proves this old adage wrong with its wind-powered, solar-powered, floating environmental classroom, The Learning Barge.
The objective of The Learning Barge is not only to teach visitors how they can help restore the Elizabeth River, but to exemplify these actions on the barge itself. Live floating wetlands demonstrate how these habitats absorb polluted stormwater runoff, composting toilets offer an alternative to flushing, and a rainwater system collects water to reuse. Visitors to this “green barge” can see firsthand how these actions help improve the Elizabeth River’s health.
The Learning Barge's innovation has earned it the 2011 Sea World & Busch Gardens Environmental Excellence Award, which is presented to outstanding grassroots environmental education programs across the country.
(Image courtesy Elizabeth River Project/Facebook)
Since 2009, more than 10,000 students have visited the floating classroom. This year, up to 60 students can set to sea at once on the barge. Three new stations (sun, wind and rain) focus on renewable energy technology.
The barge's field trip education programs were designed by local educators to meet Virginia standards for most subjects (not just science). The Elizabeth River Project even provides pre-and post-field trip activities, including art projects (sending a message in a bottle), journaling exercises (writing a letter to Princess Elizabeth) and more.
The Elizabeth River Project also gets adults involved in stewardship efforts through its River Star brand, a certification that home and business owners can earn after they take seven easy river-friendly steps. Some of the steps are so easy that they actually require you not to do something (such as not feeding geese, not flushing medicines and not dumping grease down the sink). Take a peek at this short video to see some River Stars in action.
The River Star certification is also applied to schools. There are already 128 River Star schools – more than half of the total 200 public and private schools in the Elizabeth River watershed. Students at River Star schools create herb and butterfly gardens, plant marsh grasses, learn how to compost and more.

Although the River Star certification is available only to Hampton Roads area residents, the seven easy steps are a great idea for anyone to try.
The Elizabeth River Project offers even more creative ways to help and enjoy the river:
West Virginia may be far from the sailboats and blue crabs that we normally associate with the Chesapeake Bay. But folks at the Cacapon Institute in the state’s eastern panhandle are helping students install rain gardens, speaking with local farmers about reducing pollution, and spearheading community education initiatives – all in the name of helping the Potomac River and the Chesapeake Bay.
(Image courtesy mdmarkus66/Flickr)
Founded by a husband and wife team in 1985, the Cacapon Institute was originally known as the Pine Cabin Run Ecological Laboratory. PCREL was established to research and teach Appalachian natural history and water quality issues around the Cacapon River, an 80-mile-long Potomac tributary that is designated by the EPA as an American Heritage River.
The Cacapon Institute’s dual mission of scientific research and education makes it stand out from organizations that emphasize one over the other. Today, the Cacapon Institute continues to balance community education and outreach with science “experiments” such as deer fencing and trout restoration.
Ever get sick of all this environmental talk? Do you think you could stop pollution if you were a county land manager or decision maker? The Cacapon Institute gives K-12 students that opportunity through its interactive Stream Cleaner Environmental Forum.
Stream Cleaner allows users to decide how land is used and see the effects of those decisions on natural resources. It’s an interactive, engaging way for students to learn about water and pollution issues.
The program is part of the greater Potomac Highlands Water School, a website that provides resources for teachers and students seeking to learn about their local environment. Slideshows, interactive games and vocabulary lists make it a hybrid of “old school” and digital learning. No matter what generation you belong to, it's worth a visit.
The Cacapon Institute isn’t just teaching students vocabulary words; it’s challenging them to collaborate on water quality projects.
(Image courtesy Cacapon Institute/Facebook)
Each spring, Cacapon sponsors the Stream Cleaner Environmental Forum, a program in which classes work together to develop solutions to specific, real-world pressures on the Potomac and the Bay.
Participating students learn from the best; collaborators range from local farmers and businesses to state and federal agencies. Projects such as Farmers as Producers of Clean Water hinge on input from local farmers about which best management practices they’d most likely adopt. By understanding the needs of different stakeholders and working with them to develop mutually beneficial solutions, Cacapon is creating a community that’s strengthened by cooperation, rather than oppressed by regulation.
The Cacapon Institute hopes that by starting with the younger generation, it can engage the wider community. This statement on its website says it all:
As educators, we work to create a future where a stream without a buffer looks as out of place as a smoker in a conference room looks today. To foster that vision, our environmental education efforts focus on students first and, through them, the larger community.

Here in the Chesapeake Bay region, it’s easy to use winter as an excuse for, say, drinking lattes, neglecting your exercise regimen and catching up on your favorite television show instead of getting outdoors. These indulgences provide me with some comfort in the face of frigid temperatures, high winds and slick road conditions.
But as my jeans get tighter and my skin gets paler, I’ve become inspired to conquer the season and all its hazards (realistically speaking, that is). Rather than hibernating like an animal, I’m putting my four-wheel-drive to use and showing winter who’s boss!
From cross country skiing to bird watching to doing donuts on frozen lakes, there are some outdoor experiences you can only have during our coldest season. We’ve compiled a list of six great places across the Bay watershed to experience winter. Just think how much better that hot cocoa will taste after you’ve felt the winter wind in your face!
If a winter flu’s got you down, a dip in Berkeley Springs may save your health. George Washington himself frequented Berkeley Springs to bathe in the warm mineral waters that flow from five main sources in the town. The springs discharge 2,000 gallons of clear, sparkling water per minute. The water remains at 74.3 degrees Fahrenheit year-round. It isn’t quite hot tub temperature, but it’s still warmer than a typical winter day.
The town even holds a Winter Festival of the Waters each year to celebrate the springs!

A drive through rolling hills, orchards and farmland will bring you to Catoctin Mountain Park and Cunningham Falls State Park, located the base of the Appalachian Mountains. Rock climbing, trout fishing, cross country skiing, winter hiking and horseback riding are just a few of the activities these recreational areas offer.

The forests covering the parks are known as “second growth.” The “first growth” forest was logged extensively in the 18th and 19th centuries to support local agriculture and produce charcoal for the nearby Catoctin Ironworks Furnace. In the 1930s, the land was set aside and reforested by President Roosevelt’s Work Progress Administration.
Hikers and cross country skiers will come across waterfalls and large, 500 million-year-old boulders. These rocks have been exposed as the Appalachian Mountains have flattened out over time. Trails at Cunningham Falls center around the waterfall for which the park is named. Known locally as McAfee Falls, it is the largest cascading waterfall in the state of Maryland.
Venture to Hills Creek State Park, near the Pennsylvania/New York border, and you’ll find yourself surrounded by nothing but forests. Four hundred acres of state park land are bordered by nearly 13,000 acres of state game lands, making the park an ideal destination for trappers and hunters. Winter sports fanatics will be in heaven – the park’s five and half miles of trails are open to hiking and cross country skiing in winter.

Take the kids sledding on the hill near the seasonal beach; with adequate snow cover, you’ll be able to fly! If you’re lucky, you may be able to ice skate on the 137-acre Hill Creek Lake. (The park doesn’t monitor ice thickness, but does provide updates on winter conditions.)
In the winter, scenic mountain vistas are all the more impressive; without any greenery in the way, you can see for miles. For breathtaking winter views, visit Loyalsock State Forest, part of Pennsylvania’s Endless Mountain region. The park’s elevation is relatively high for the Chesapeake Bay watershed, which means you can count on winter conditions every year.
The park manages two trails specifically for cross country skiing, but skiers are welcome anywhere. Thirty-five miles of trails transverse the park, connecting visitors to a 130-mile regional trail system. Snowmobiling is also popular here.

If winter travel isn’t in the cards for you, look no further than Patuxent Research Refuge, the 13,000-acre wildlife refuge halfway between Washington, D.C., and Baltimore, Maryland. You’ll be surprised by how secluded you’ll feel just 20 minutes off I-295 (Baltimore/Washington Parkway).
Borrow binoculars and birding guides from the visitor center and walk the family-friendly trails to catch a glimpse of cardinals, tundra swans and Canada geese. The visitor center also hosts public programs for kids and houses life-sized “stuffed” animals and interactive exhibits that explain the National Wildlife Refuge system.
Seasonal hunting is also popular on the refuges’ North Tract.
If you’re still itching to get a little snow, head to the southernmost selection on our list. During this time of year, Shenandoah’s weather is unpredictable – often 10-20 degrees cooler than temperatures in the valley. Leafless trees allow you to see for miles across the park’s nearly 200,000 acres. Portions of Skyline Drive and visitors’ services are closed through March, but hiking, backcountry camping and simple Sunday drives are still welcomed! Look for bobcat tracks in the snow along the trails. If you’re brave and fit, check out the magnificent view at the top of Old Rag.

Now you tell us: what’s your favorite Chesapeake Bay place to explore in winter?
Though the final figures on the overall health of the Bay’s underwater grasses won’t be available for a few months, in late November, scientists with the Chesapeake Bay Program’s (CBP’s) team that monitors the abundance of the Bay’s grasses had a pleasant surprise. Aerial survey images of the vast grass-filled Susquehanna Flats, the circular area where the Susquehanna River meets the Bay, were not pictures of devastation as was feared, but pictures of health, showing that these valuable Bay habitats survived the fall’s deluge of runoff and sediment better than expected.
During Hurricane Irene and Tropical Storm Lee, experts out monitoring the effects of these storms noted large tangles of all varieties of uprooted Bay grasses floating downstream. Based on these visual accounts and their knowledge of the devastation that events such as Tropical Storm Agnes wrought on the Bay’s grass beds almost forty years ago, hopes among scientists were not high for these habitats, which are a critical food source for over-wintering waterfowl at this time of year and that are vital as shelter for juvenile Bay creatures in the spring.
“We were incredibly surprised at how much of the grass bed remained on the Flats,” says Robert Orth of Virginia Institute of Marine Sciences (VIMS) and leader of the team that conducts the annual survey of Bay grasses. “While we did see some declines along the flanks and edges of that big bed, my gut feeling says next year should be ok for grass beds up there. And the fact that we are now seeing overwintering waterfowl in our photographs is a good sign that lots of food is available.”
CBP’s Associate Director for Science Rich Batiuk commented, “Back on those days of Tropical Storm Lee, looking at the deluge of water over the Conowingo Dam, I would’ve bet that we had lost the Flats grasses entirely. Their survival is a good example of how large, dense beds can survive extreme conditions and another indicator of the Bay’s resilience.”

The James River Association (JRA) has given Virginia’s James River a C in its latest State of the James report, down from a C+ in the last report two years ago, despite rebounding underwater bay grass beds and resurgent shad and eagle populations.

The State of the James measures four critical indicators of river health: key fish and wildlife species, habitat, pollution, and restoration and protection actions. The river received a 53 percent score, meaning it is just over the halfway point of being fully healthy. However, this score is down 4 percent from two years ago.
The largest score decline was observed in the pollution category, which fell 11 percent from the previous report’s score. According to the JRA, progress to reduce nutrient pollution has stalled, and sediment pollution actually increased due to large storms.
“The James River is healthier today than it has been in decades, but the kind of progress we have made toward improving the health of the river is waning,” said JRA Executive Director Bill Street. “Unfortunately, unless we redouble our commitment to controlling pollution flowing into the James, we run the real risk of erasing the progress we have worked so hard to achieve.”

Gulls call to each other, belted kingfishers swoop down into the seagrass, monarchs chase the wind, and Alicia and I snap photographs of as much of it as we can. Fisherman Island is only open to the public during this time of year, and it is very likely that this trip will be our only opportunity to visit the tiny island at the southernmost tip of the Delmarva Peninsula.
Although thousands of motorists pass over the 1,850-acre land mass each day as they drive across the Chesapeake Bay Bridge-Tunnel, few of them know that this area is one of only 17 sites classified as a “wetland of international importance.” Thousands of migratory birds stop here each fall and spring, and monarchs feed on native plants as they make their winter trip to Latin America.
The refuge is closed to the public because many of these species, such as brown pelicans and royal terns, are sensitive to threats from humans.
The Eastern Shore of Virginia National Wildlife Refuge, part of the U.S. Fish and Wildlife Service, manages Fisherman Island. Refuge law enforcement makes sure that the public – and yes, even fishermen – stay away.
Alicia and I were afforded access to Fisherman Island through Chesapeake Experience, a non-profit organization that offers summer camps, eco paddles, corporate retreats and experience-based environmental education for educators and students. Chesapeake Experience Director Jill Bieri and two refuge staff members led a morning walk on the island’s nearly unspoiled beach and an afternoon kayak tour from the Chesapeake to the Atlantic.
But this trip is a different kind of Chesapeake experience for us, coming from Annapolis, where the Bay’s brackish water forms a distinctive landscape.
Most of the tour participants are avid birders and have come prepared with binoculars. We see many yellow-rumped warblers, or “butter rumps,” (Dendroica coronate) squeaking back and forth across the path.
There are plenty of other interesting features to observe at Fisherman Island, including:
Although we find treasures that we’re not likely to see in Annapolis, we also saw something disappointing: plastic bags that have washed up on shore and are now buried deeply in the sand.
To me, this illustrates why efforts to restore the Bay need to collaborative, involving agencies like the Fish and Wildlife Service, non-profits like Chesapeake Experience, and regular people like you and me. Although this tract of land is hardly touched by the public, and managed meticulously by the government, it is still vulnerable to the pollution that is happening throughout the Bay.
That afternoon, we paddle to where the Chesapeake Bay pours into the Atlantic Ocean, following the meandering path of the water through the marsh. Sitting on my kayak in this water, I feel it drift in and out of the Bay, and realize that the boundary lines between ocean and bay are fuzzy, or even, invisible.
A great blue heron watches us kayak into the waves. Our group slowly paddles to him, waiting for his five-foot wing span to cast a shadow over us. His flight makes our cameras snap and mouths hang open.
Jill instructs us to turn back before the waves get too rough. After all, we’re only novice kayakers!
Our homeward bound drive along Route 13 reveals abandoned homes alongside tents selling Virginia pecans, fireworks and cigarettes, all of them advertising their products with home-made, home-painted signs dotting the side of the road.
Mobile homes, their porches decorated with pots and pans and people in rocking chairs, sit on large tracts of land that I imagine to once have been profitable tobacco or cotton farms.
As the sun sets, these surroundings disappear, and we have only the stars to look at until we reach Annapolis.
The Potomac Conservancy has awarded the Potomac River’s health a barely passing “D” grade in its fifth annual State of the Nation’s River report.
Population growth and poor land use practices are the primary causes for the river’s pollution, according to the report. The Potomac River’s “two worlds” – rural farms and mountains to the west and the urban landscape to the south – pose different challenges.
Throughout the report, the Potomac Conservancy provides a vision of greater accountability, efficiency and enforcement actions to improve land use practices and water quality. These include strong federal and state stormwater laws, and changing local codes to protect riparian forest buffers, promote well-managed farms, better regulate large farm operations and treat pollution before it enters local waterways.
“We know what needs to be done, but this region is going to have to find the political will to make the hard choices,” according to Potomac Conservancy President Hedrick Belin. “Investing a dollar today to reduce pollution will return clean water dividends for years to come.”

On a brisk Saturday in October, 160 volunteers collect 3.5 tons of discarded children’s toys, plastic bottles, crushed automobiles, and various other kinds of trash from their local Chesapeake Bay tributary, the Rappahannock River.
The volunteers, many of them students at the University of Mary Washington and Mountain View High School, are participants in a clean-up hosted by Friends of the Rappahannock, a non-profit advocacy, restoration and education organization based in Fredericksburg, Virginia.
Friends of the Rappahannock – also known as “River Friends” or “FOR” – hosts fall and spring clean-ups each year. But its environmental efforts span the entire year. From engaging at-risk youth in streamside restoration activities to helping residents construct rain gardens in their yards, FOR’s volunteers are saving the Chesapeake Bay in a number of ways.
“We give people the chance to make a difference, to go home feeling that whatever they’ve done, they’ve made some type of positive impact,” says John Tippett, FOR’s executive director. “Providing a range of these fulfilling opportunities is what keeps our volunteers coming back.”
FOR’s diverse collection of volunteer programs are critical for a river so geographically expansive: the Rappahannock travels from the Blue Ridge Mountains to the Chesapeake Bay, transecting landscapes that range from agricultural (in the headwaters and tidewaters) to urban (near Fredericksburg).
Along the its course, the river experiences nearly every type of pollution pressure that can be found in Virginia: from livestock manure on farm fields to fertilizer from suburban lawns.
How does FOR help reduce these pollution pressures? The group’s strategy varies from community to community. FOR takes into account the pollution source (anything from animal waste to fertilized lawns), but also considers the interests of residents, the involvement of local governments, and the availability of staff and volunteers.
“We strive to develop a variety of activities and volunteer opportunities to engage our members and other community members,” explains Sarah Hagan, volunteer coordinator at FOR.
Here are a few of our favorite ways you can get involved with FOR:
Contact FOR to get involved today! And if you don’t live near the Rappahannock, don’t worry; there are plenty of small, volunteer-based watershed organizations throughout the Chesapeake Bay region that you can get involved with!

Just a scenic two-hour drive from Washington, D.C., the 38-mile-long Passage Creek weaves in and out of Fort Valley, Virginia, a part of the Shenandoahs so sheltered that it has been called "a valley within a valley."
In the 1800s, Passage Creek was home to five- and six-pound trout. Today, the Virginia Department of Game and Inland Fisheries stocks the creek with trout three times each summer. Fisherman, local residents and conservationists are working together to protect habitat for trout and other important species.
Although there aren’t any gigantic trout (yet!), stepping onto the banks of Passage Creek is, in many ways, like taking a step back in time.
Passage Creek is considered to be a relatively healthy stream compared to other Virginia waterways, many of which have degraded habitats due to agriculture, urbanization and logging, according to the Potomac Conservancy, which has launched a restoration campaign in the area.
In addition to fishing its waters, visitors to Passage Creek cancamp in the adjacent George Washington National Forest, view the nation's first Civilian Conservation Corps camp or hike around the Elizabeth Furnace Recreation Area, one of many iron ore furnaces constructed in Shenandoah Valley during the 1800s.
Visiting? Look for freshwater mussels (a sign of good stream health), salamanders, black bears, coyotes, wild turkeys and luna moths!
And if you're thirsty, look around! The area's freshwater springs first came to the public's attention in the 1850s, when a man named E.H. Munch built a "Seven Fountains" resort that treated guests to each of the seven kinds of mineral waters found in the area. Although the resort closed after the Civil War, many friendly area residents can lead you to a spring or two.
Four projects and individuals in Maryland, Pennsylvania and Virginia have been recognized as Chesapeake Forest Champions for their contribution to Chesapeake Bay restoration through the promotion of trees and forests.
The inaugural Chesapeake Forest Champion contest honored recipients in four categories: most innovative, most effective at engaging the public, greatest on-the-ground impact and exceptional forest steward/land owner.
The "most innovative" award went to Adam Downing and Michael LaChance of Virginia Cooperative Extension and Michael Santucci of the Virginia Department of Forestry for their Virginia Family Forestland Short Course program. The team tackled a critical land conservation challenge: intergenerational transfers of family farms and forests, and the need to educate land owners on how to protect their land. Through the land transfer plans developed in this program, more than 21,000 acres of Virginia forests are expected to remain intact, family-owned and sustainably managed.
The "most effective at engaging the public" champion was ecologist Carole Bergmann from Montgomery County, Maryland. Bergmann created the Weed Warrior program in response to a significant invasive plant problem in the county's forests. To date, approximately 600 Weed Warriors have logged more than 25,000 hours of work removing and monitoring invasive weeds.
The "greatest on-the-ground impact" award went to David Wise of the Chesapeake Bay Foundation for his leadership in restoring riparian forest buffers through the Pennsylvania Conservation Reserve Enhancement Program (CREP) partnership. Since 2000, Pennsylvania CREP has restored more than 22,000 acres of forest buffers -- more than all the other Chesapeake Bay states combined.
The "exceptional forest steward/land owner" champion was Susan Benedict of Centre County, Pennsylvania, for her work running a sustainable tree farm. Benedict has implemented many conservation projects on her family's land, such as planting habitat to encourage pollination in a forested ecosystem.
The Chesapeake Forest Champion contest was sponsored by the U.S. Forest Service and the Alliance for the Chesapeake Bay as part of the International Year of Forests. The four Chesapeake Forest Champions were honored earlier this month at the 2011 Chesapeake Watershed Forum in Shepherdstown, W.Va.

Virginia will close its winter blue crab dredge fishery season for the fourth year in a row in a continued effort to rebuild the Chesapeake Bay’s crab population.
The Virginia Marine Resources Commission voted 9-0 to close the fishery at a meeting on Sept. 27. According to the commission, although great progress has been made to restore blue crabs, more work remains to bring the population back to healthy, sustainable levels.
Visit the commission’s website to learn more about the blue crab fishery and the closure.
Scientists are examining the possibility that Atlantic sturgeon – a prehistoric fish whose population is so low that it may be listed as an endangered species – may spawn more than once per year in the James River.
In early September, biologists with Virginia Commonwealth University captured a female sturgeon leaking eggs near the confluence of the Appomattox and James rivers. This area may be a place where migrating fish adjust to less salty water before moving upstream to spawn.
If the Atlantic sturgeon is placed on the federal Endangered Species List, the multiple spawning run discovery could increase the amount of time that spawning-age fish are protected each year.
Read this article from the Bay Journal to learn more about Atlantic sturgeon on the James River.

Scientists with the Virginia Institute of Marine Science and other Bay Program partners have released a mid-year update on bay grass monitoring in the Chesapeake Bay.
Some highlights of the mid-year monitoring update include:
The full results of the Bay Program’s annual bay grass monitoring will be released next spring.
Visit VIMS’s website to learn more about bay grass monitoring.
Virginia Gov. Bob McDonnell has signed into law a bill that prohibits the sale, use and distribution of lawn fertilizer containing phosphorus. The legislation will go into effect on Dec. 31, 2013.
The law also prohibits the sale of deicers containing urea, nitrogen or phosphorus. Additionally, golf courses must implement nutrient management plans by 2017.
Phosphorus is one of the two main types of nutrients that pollute the Bay and its local waterways. Too much phosphorus runoff leads to algae blooms and low-oxygen “dead zones” where underwater life cannot survive.
The National Oceanic and Atmospheric Administration (NOAA) will launch its last Chesapeake Bay “smart buoy” next week off First Landing State Park in Virginia Beach.
The First Landing smart buoy is one of 10 buoys in NOAA’s Chesapeake Bay Interpretive Buoy System (CBIBS). The network of buoys provides boaters and scientists with real-time weather and water data such as temperature, wind speed and dissolved oxygen levels. Teachers can also use the data to support their classroom lessons.
Other smart buoys are located in the Susquehanna, Patapsco, Potomac and James rivers, as well as at several sites in the main Bay.
For more information about CBIBS and the Chesapeake Bay smart buoys, visit buoybay.noaa.gov.
Virginia’s Chesapeake Bay Restoration Fund Advisory Committee is accepting applications for nearly $308,000 in grant funding for Chesapeake Bay-related education and restoration activities. The funding is from sales of Virginia’s “Friend of the Chesapeake” license plates.
Last year, 58 grantees received approximately $312,000 in funding. Since 1996, the state has awarded nearly $6 million.
Two types of project proposals will be accepted: projects that increase public awareness about Chesapeake Bay restoration, and action-oriented projects that help restore and conserve the Bay.
The deadline for submitting a proposal for the 2012 grant is October 1, 2011. Grants will be awarded in May-June 2012.
For more information, visit the Chesapeake Bay Restoration Fund Advisory Committee’s website.
Biologists with the Virginia Department of Conservation and Recreation (DCR) are mapping phragmites along the York River as part of a strategy to control the invasive marsh plant.
The agency will use the phragmites location data to develop a web-based mapping tool. Landowners along the Mattaponi, Pamunkey and York rivers can use the map to see if phragmites is growing on their property. The map should be available on DCR’s invasive species page by winter.
“DCR is developing an improved web-based phragmites mapping application that will allow landowners to assess phragmites invasions on their own land in order to make plans for its control,” said DCR Project Manager Rick Myers.
Phragmites is a tall, perennial grass that grows in marshes. The non-native form of phragmites dominates other plants, forming monocultures that do not provide good habitat for wildlife. Although Virginia has treated thousands of acres with approved herbicides, phragmites is spreading fast because too few landowners are controlling it.

The Chesapeake Executive Council announced progress toward Chesapeake Bay cleanup milestones, discussed plans for meeting requirements of the Bay “pollution diet,” and encouraged individual Bay stewardship at its annual meeting on July 11 in Richmond, Virginia.
Executive Council members in attendance included U.S. Environmental Protection Agency Administrator and Executive Council Chair Lisa Jackson; Virginia Gov. Bob McDonnell; Maryland Gov. Martin O’Malley; Pennsylvania Gov. Tom Corbett; District of Columbia Mayor Vincent Gray; Chesapeake Bay Commission Chair Sen. Michael Brubaker; U.S. Department of Agriculture Deputy Secretary Kathleen Merrigan; and representatives from Delaware, New York and West Virginia.
Chesapeake Bay Program partners are currently working toward short-term pollution reduction goals called milestones. All seven Bay jurisdictions are currently on-track or ahead of schedule in meeting these milestones. The deadline for the current set of two-year milestones is December 31, 2011.
Executive Council members also talked about their watershed implementation plans (WIPs), local restoration plans that show how each jurisdiction will meet pollution reductions required by the Chesapeake Bay TMDL. The jurisdictions are now in the second phase of developing their draft plans, which are due at the end of 2011.
Additionally, the Bay Program’s three advisory committees – Citizens, Local Government, and Scientific and Technical – presented to the Executive Council about Bay restoration activities from their unique areas of expertise.
The 2011 Executive Council meeting was held at the Maymont Foundation, located on the James River in Richmond. Executive Council members spent part of the afternoon touring exhibits on topics such as native plants, Bay-friendly lawn care, and soil health and testing. The location was chosen to highlight the meeting’s “Get Grounded in Tour Watershed” theme, which stresses the importance of connecting people with their local waterways. Through its Nature Center and educational programs, Maymont offers local residents a place to learn about and connect with Virginia’s environment.
"The focus of our discussions today was on empowering every citizen in the Bay watershed to be part of restoring these important waters,” said Jackson. “The actions of federal, state and local governments are just the beginning of revitalizing the Bay. We are also counting on the partnership of millions of people who live in this region to join in protecting the waters that support their health, their environment and their economy."
The Executive Council sets the policy agenda for the Chesapeake Bay Program. Visit our Chesapeake Executive Council page for more information.
The Virginia Department of Environmental Quality (DEQ) is seeking federal designation of several Northern Neck creeks and rivers as “no-discharge zones,” which would prohibit overboard dumping of treated or untreated sewage to reduce bacteria contamination in local waterways.
No-discharge zones promote the use of pump-out facilities and dump stations to safely dispose of sewage from boats. The certification of marine sanitation devices, which treat and/or hold sewage on vessels, is targeted to meet fishing and swimming standards in local rivers.
Shellfish harvest restrictions due to fecal bacterial contamination are common throughout Virginia’s tidal Chesapeake Bay tributaries. This contamination has been linked to a variety of sources, including failing septic systems and sewage discharge from boats.
DEQ is proposing no-discharge zones for select water bodies in Richmond, Lancaster, Northumberland and Westmoreland counties. The four-county proposal will be sent to the U.S. Environmental Protection Agency for review by July.
Virginia already has no-discharge zones in the Lynnhaven River in Virginia Beach, and in Broad Creek, Jackson Creek and Fishing Bay in Middlesex County. In the Lynnhaven River, one marina reported that pump-outs nearly doubled when the tributary was designated as a no-discharge zone. Fewer boat sewage discharges combined with other pollution-reduction measures led to the re-opening of 1,462 acres of condemned shellfish growing areas to commercial harvest.
DEQ and the Northern Neck Planning District Commission will host a public meeting on June 14 to summarize the no-discharge zone application. The meeting will be held at 6 p.m. in the A.T. Johnson Alumni Museum in Montross. DEQ will accept public comments on the application June 15 through July 15, 2011.
Visit DEQ’s website to learn more about Virginia’s “no-discharge zone” program.
Waterman hauled up more than 10,000 derelict “ghost pots,” lost fishing nets and other assorted metal from the Chesapeake Bay and its rivers this winter as part of Virginia’s Marine Debris Removal Program.
In total, more than 28,000 ghost pots – abandoned crab pots that litter the Bay’s bottom – have been removed over the past three years. Watermen removed more marine debris this year than in either of the last two years.
Ghost pots inadvertently trap and kill crabs, fish and other wildlife. Scientists have determined that each functional ghost pot can capture about 50 crabs a year. Ongoing research suggests 20 percent of all the crab pots set in a year are lost, primarily due to storms or boat propellers.
This year, a total of 9,970 ghost pots were recovered. In addition, 52 lost nets and 532 other pieces of junk were hauled up, including a jon boat, a portable generator frame and a large metal crate used to transport hunting dogs.
The recovered crab pots were found to have captured more than 11,000 animals, including thousands of crabs, as well as turtles, fish, eels and whelks. More than 27,000 animals, many already dead, have been found in ghost pots retrieved since 2008.
The removal program, funded by NOAA through the Virginia Marine Resources Commission and administered by the Virginia Institute of Marine Science (VIMS), pays out-of-work watermen to use side-imaging sonar units to detect and retrieve ghost pots and other marine debris. It is the first and largest program of its kind in the United States.

Underwater bay grasses covered 79,675 acres of the Chesapeake Bay and its tidal rivers in 2010, according to data from scientists with the Chesapeake Bay Program. This is a 7 percent decrease from 2009, when bay grasses covered 85,914 acres of the Bay’s shallows.
Despite the drop, the 2010 bay grass acreage estimate ranks as the third-highest Bay-wide acreage since 1984, when the annual survey began.
"Even with the decreases in the 2010 bay grass coverage, the patterns are similar to previous years,” said Lee Karrh, living resources assessment chief with the Maryland Department of Natural Resources and chair of the Bay Program's SAV Workgroup. “Many of the fresh and low salinity areas have very high abundances, including 16 that have reached their restoration targets. However, the saltier parts of the Bay continue to struggle, with most areas well below the restoration goals, with only the mouth of the James River exceeding the goal.”
Bay grass abundance is currently at 43 percent of the Bay Program’s 185,000-acre goal. This goal is based on approximate historic bay grass abundance from the 1930s to present.
“We were pleased that grasses remain healthy and abundant in two areas where nutrient pollution was reduced: the upper Potomac River and Susquehanna Flats,” said Bob Orth, scientist with the Virginia Institute of Marine Science and leader of the baywide annual survey. “However, the overall condition for bay grasses remains one of concern with many areas still having few, if any, grass beds.”
In the upper Bay (from the Susquehanna Flats to the Chesapeake Bay Bridge), bay grasses covered about 21,353 acres. This is a 10 percent decrease from 2009. Large increases were observed in the Chesapeake and Delaware Canal and part of the Sassafras River. However, these were offset by large decreases in local rivers, including the Bush, Bohemia and Magothy. The massive grass bed in the Susquehanna Flats continues to dominate this area.
In the middle Bay (from the Chesapeake Bay Bridge to the Potomac River and Pocomoke Sound), bay grass acreage decreased 11 percent to 35,446 acres. Most segments in this part of the Bay lost grasses. The largest percentage decreases occurred in the middle and lower central Bay, as well as the Choptank, Honga, Patuxent and Potomac rivers. Increases were seen in Tangier and Pocomoke sounds and the Manokin and Big Annemessex rivers, where eelgrass continued to come back following a 2005 die-off.
In the lower Bay (south of the Potomac River), scientists mapped 22,876 acres, a 1 percent increase from 2009. This is the fourth year that bay grasses in this part of the Bay have increased since 2005, when hot summer temperatures caused a dramatic large-scale eelgrass die-off. Most of the gains were in the upper Rappahannock, lower Piankatank, and the upper section and mouth of the James River. These gains offset losses in other areas.
“In 2010, our big concern arose in the lower Bay where eelgrass appeared to suffer another setback from the incredibly hot summertime temperatures,” said Orth. “Since we had mapped those beds prior to the heat wave, losses there are not reflected in our final figures. We believe the really hot summer temperatures in the early part of the growing season may have just cooked the grasses before we were able to map them, e.g. parts of the Honga River. The changes also occurred in areas dominated by just one species, widgeongrass, which has been shown to be a boom or bust species. 2010 may have been the hottest on record but it was those summer time temperatures in June that may have tipped the scale for SAV in some areas.”
Bay grasses – also known as submerged aquatic vegetation or SAV – are a critical part of the Bay ecosystem. They provide underwater life with food and habitat, absorb nutrients, trap sediments, reduce erosion, and add oxygen to the water.
Bay grasses are also an excellent measure of the Bay’s overall condition. The health of bay grasses is closely linked with Bay health. Annual bay grass acreage estimates are an indication of the Bay’s response to pollution control efforts.
Annual bay grass acreage is estimated through an aerial survey, which is conducted from late spring to early autumn. For more information about the aerial survey, and to view an interactive map of bay grass acreage throughout the Bay and its tidal rivers, visit VIMS’ website.
The Chesapeake Bay’s blue crab population is at its second-highest level since 1997, according to results from the 2011 Blue Crab Winter Dredge Survey. At 460 million crabs, the blue crab population is nearly double the record low of 249 million in 2007.
Additionally, the survey shows that there are 254 million adult crabs in the Bay, a figure that is above the 200 million population target for the third year in a row. This marks the first time since the early 1990s that there have been three consecutive years where the adult population was above the target.
These figures indicate that emergency crab management measures put into place in 2008 are helping the Bay’s blue crabs recover, according to the Maryland Department of Natural Resources (DNR) and the Virginia Marine Resources Commission (VMRC).
“We continue to realize the benefits of the very tough decisions we made three years ago – decisions that are bringing us closer to our ultimate goal: a self-sustaining fishery that will support our industry and recreational fisheries over the long term,” said Maryland Gov. Martin O’Malley.
“The stock’s improved status from just a few short years ago is neither a random event nor a reflection of improved environmental conditions,” said Dr. Rom Lipcius, who directs the Virginia component of the dredge survey for the Virginia Institute of Marine Science (VIMS).
The unusually high crab abundance allowed watermen to harvest more than 89 million pounds of crabs, the largest amount since 1993. In addition, recreational crabbing license sales increased by 8 percent in 2010. However, the combined commercial and recreational blue crab harvest did not exceed the target of 46 percent. This shows that a healthy crab industry can coexist with stronger regulations, according to VMRC.
Despite these positive figures, overall crab abundance declined due to this past winter’s deep freeze that killed as many as 31 percent of Maryland’s adult crabs, compared to about 11 percent in 2010. Crab reproduction – which is heavily influenced by environmental conditions – was also lower in 2011.
“It was a harsh winter and crab mortality was higher than normal. In fact, it was the worst we’ve seen since 1996,” said VMRC Commissioner Steven G. Bowman. “Thankfully, we acted when we did in 2008 to begin rebuilding the crab population, or the crab census results we see today would be grim indeed.”
“The evidence indicates we’ve succeeded in rebuilding the stock to a degree that it can withstand a perfect storm of rapid temperature drop as crabs move into their overwintering grounds in the lower end of the Chesapeake Bay, followed by a prolonged bout of cold weather,” said VMRC Fisheries Chief Jack Travelstead.
Abundance estimates for young of the year, mature female and adult male crabs are developed separately. Together, these groups of crabs will support the 2011 fishery and produce the next generation of crabs.
The annual Blue Crab Winter Dredge Survey is the primary assessment of the Bay’s blue crab population. Since 1990, Maryland DNR and VIMS have sampled for blue crabs at 1,500 sites throughout the Chesapeake from December to March. By sampling during winter – when blue crabs “hibernate” by burying themselves in the mud – scientists can develop the most accurate estimate of the Bay’s blu crab population.

West Virginia will invest $6 million annually for 30 years toward wastewater treatment plant upgrades that will reduce nutrient pollution to the Potomac River and the Chesapeake Bay.
The money, which will come from excess state lottery funds, will fund about $85 million in bonds that will help pay for upgrades. The funding will cover about 40 percent of the expected cost for the upgrades.
The upgrades will help West Virginia meet new pollution-reduction goals that are part of the federal pollution diet for the Chesapeake Bay and its rivers. West Virginia has 13 wastewater facilities that need to be upgraded to meet nutrient limits.
Acting Gov. Earl Ray Tomblin signed the bill into law on April 6.
Virginia is poised to pass a law banning the sale of fertilizer containing phosphorus, a major pollutant in the Chesapeake Bay and its rivers.
Lawns, parks, golf courses and other grass-covered areas cover 3.8 million acres of the Bay watershed. Most established lawns do not need phosphorus, but the majority of commonly used lawn fertilizers include phosphorus in their nutrient mix.
Once it goes into effect in 2013, the law will reduce an estimated 230,000 pounds of phosphorus pollution from reaching the Bay and Virginia rivers each year. This is 22 percent of Virginia's 2017 phosphorus reduction goal.
The law will also:
A variety of groups, including the Chesapeake Bay Foundation, James River Association, Home Builders Association of Virginia and Virginia Association for Commercial Real Estate, supported the legislation.
The legislation was passed by the Virginia Senate and House of Delegates. It now awaits Gov. Bob McDonnell's signature.
When passed, Virginia will become one of nine states that restrict the use or sale of phosphorus in lawn fertilizer. Maryland and Pennsylvania are considering similar legislation.
Welcome to the latest installment of the BayBlog Question of the Week. Each week, we take a question submitted on the Chesapeake Bay Program website or a frequently asked question and answer it here for all to read.
This week’s question came from John, who asked: “What is the Chesapeake Bay Commission? Who are they and what do they do?”
The Chesapeake Bay Commission is a tri-state legislative body representing Maryland, Virginia and Pennsylvania. The commission was created in 1980 as a bi-state commission to help Maryland and Virginia collaborate and cooperate on Chesapeake Bay management. Pennsylvania became a member in 1985, after which time the Commission began advising each state's general assembly on matters deemed to be of Bay-wide concern.
The Commission also serves as the legislative arm of the Chesapeake Bay Program, advising each of the jurisdictions represented by the Bay Program partnership.
Since its establishment, the Commission has worked to promote policy in several areas that are vital to Chesapeake Bay restoration, including nutrient reduction, fisheries management, toxics remediation, pollution prevention, habitat restoration and land management.
The Commission has 21 members from the three states. Among those members are:
The chairman position rotates among the three states each calendar year. As of January 2011, Pennsylvania State Senator Mike Brubaker took over as Chairman of the Commission.
One of the Commission's main goals is to make sure that member states' common interests are thoroughly represented in regard to any federal government actions that may affect them. This has become a vital part of the process of developing the Chesapeake Bay Total Maximum Daily Load (TMDL) and Executive Order strategies.

Richmond, Virginia’s Capitol Square is about to become one of the most environmentally friendly capitols in the nation, with a series of green construction projects set to begin this summer.
The projects, including a retrofit of the capitol grounds and select streets and alleys, aim to reduce polluted stormwater runoff to the James River, a major tributary of the Chesapeake Bay.
The “Greening Virginia’s Capitol” project was developed by the Virginia Department of Conservation and Recreation (DCR), the Virginia Department of General Services (DGS), the City of Richmond and the Alliance for the Chesapeake Bay. The project, in the works for several years but put on hold due to budget cuts, is being funded by a $798,988 grant from the Chesapeake Bay Program and the National Fish and Wildlife Foundation.
A major goal of the project is to let stormwater slowly infiltrate into the ground, rather than flowing freely across pavement and directly into the James River. Rain gardens and pervious pavement will absorb and filter runoff, cleaning it before it can reach groundwater supplies.
All phases of the project are anticipated to be completed by spring 2011, when experts estimate that overall stormwater runoff from Capitol Square will be reduced by 64 percent. Phosphorus runoff will be reduced by 69 percent and nitrogen will be reduced by 70 percent.
The first phase of the project is to “green” of alleys at 5th and 12th streets. Other phases will include:
The Greening Virginia’s Capitol project be used by Virginia DCR as a model of how to reduce stormwater runoff in an urban setting.
The project will also show citizens and officials throughout the Chesapeake Bay watershed how simple changes can make a huge difference in the amount of polluted runoff that reaches the Bay and its streams, creeks and rivers.
Greening Virginia’s Capitol has also been selected as one of the first landscapes to participate in the Sustainable Sites Initiative (SITES), a new program testing the nation’s first rating system for green landscape design, construction and maintenance.

Underwater bay grasses covered 85,899 acres of the Chesapeake Bay and its tidal rivers in 2009, about 46 percent of the 185,000-acre baywide abundance goal, according to data from scientists with the Chesapeake Bay Program. This was a 12 percent increase from 76,860 acres in 2008 and the highest baywide acreage since 2002.
Bay grasses -- also called submerged aquatic vegetation or SAV -- are critical to the Bay ecosystem because they provide habitat and nursery grounds for fish and blue crabs, serve as food for animals such as turtles and waterfowl, clear the water, absorb excess nutrients and reduce shoreline erosion. Bay grasses are also an excellent measure of the Bay's overall condition because they are not under harvest pressure and their health is closely linked to water quality.
“The overall increase in SAV acreage in 2009 was strongly driven by changes in the middle and lower Bay zones, including Tangier Sound, the lower central and eastern lower Chesapeake Bay, Mobjack Bay, and the Honga, Rappahannock and lower Pocomoke rivers,” said Bob Orth, scientist with the Virginia Institute of Marine Science (VIMS) and leader of the SAV baywide annual survey.
Bay grass acreage increased in all three of the Bay’s geographic zones – upper, middle and lower – for just the second time since 2001.
Upper Bay Zone (from the Chesapeake Bay Bridge north)
In the upper Bay zone, bay grasses covered about 23,598 acres, just shy of the 23,630-acre goal for this area and a 3 percent increase from 2008.
Large percentage increases were observed in the Northeast River, part of the Sassafras River and the upper central Chesapeake Bay, an area just north of the Bay Bridge. However, bay grass acreage in a few local rivers, such as the Bush and Magothy, decreased significantly and offset increases elsewhere.
Overall, the massive grass bed on the Susquehanna Flats continues to dominate this zone.
“The growth and persistence of the SAV bed in the Susquehanna Flats – including the largest bed in the Bay – continues to be a major success story for bay grass recovery today,” said Lee Karrh, living resources assessment chief with the Maryland Department of Natural Resources and chair of the Bay Program's SAV Workgroup. “Many of the Bay’s lower salinity areas are doing well and seem to be driven by reductions in nutrient pollution entering the Bay. Seventeen segments in this zone have met or exceeded their restoration targets.”
Middle Bay Zone (from the Chesapeake Bay Bridge to the Potomac River and Pocomoke Sound)
In the middle Bay zone, bay grass acreage increased 15 percent to 39,604 acres, 34 percent of the 115,229-acre goal.
Eighty-four percent of the acreage increase in the middle Bay zone occurred in five segments: Eastern Bay, the Honga River, Pocomoke and Tangier sounds, and the lower central Chesapeake Bay. These changes reflect a large expansion of widgeon grass – the dominant SAV species in the middle Bay zone – as well as the continued recovery of eelgrass in Tangier Sound.
Elsewhere in the middle Bay zone, large percentage declines in bay grass acreage were observed in the Severn River and Piscataway Creek, a tributary of the Potomac River.
Lower Bay Zone (south of the Potomac River)
In the lower Bay zone, researchers mapped 22,697 acres of bay grasses – a 17 percent increase from 2008 and 49 percent of the 46,030-acre restoration goal. This is the third year that bay grasses in the lower Bay zone have increased since 2005, when hot summer temperatures caused a dramatic large-scale dieback of eelgrass.
Eighty-two percent of the acreage increase in the lower Bay zone occurred in Mobjack Bay, the lower Rappahannock River and the eastern lower Chesapeake Bay.
None of the 28 segments in the lower Bay zone saw large declines in bay grasses in 2009.
“We are cautiously optimistic about eelgrass recovery now that it is into its third year following the 2005 dieback,” said Orth. “But we are concerned about the long-term absence of eelgrass from areas that traditionally supported large dense beds, such as much of the York and Rappahannock rivers, many of the mid-Bay areas just north of Smith Island, and in the deeper areas of Pocomoke Sound. Declining water clarity noted in much of the lower Bay may be a major impediment to eelgrass recovery.”
Annual bay grass acreage estimates are an indication of the Bay's response to pollution control efforts, such as implementation of agricultural best management practices (BMPs) and upgrades to wastewater treatment plants.
Bay watershed residents can do their part to help bay grasses by reducing their use of lawn fertilizers, which contribute excess nutrients to local waterways and the Bay, and participating with their local tributary teams or watershed organizations.
Bay grass acreage is estimated through an aerial survey, which is flown from late spring to early fall. Visit VIMS’s website for additional information about the aerial survey and an interactive map of bay grass acreage throughout the Bay.
Virginia has permanently preserved more than 424,000 acres of land since 2006, surpassing Virginia Gov. Timothy Kaine’s goal of 400,000 acres conserved during his term.
The 424,000 acres of land were conserved so they could be protected from development and used by Virginia residents and visitors for outdoor activities such as fishing, boating, hiking and birding.
“Virginians expect to be able to explore and enjoy those lands purchased with public funds,” Governor Kaine said. “We have been mindful of the fact that we are stewards of their lands and resources.”
The land will be used to create five state forests, three state parks, three wildlife management areas and 13 natural area preserves.
Some of the protected parcels of land include:
January 2010 -- The head of the U.S. Environmental Protection Agency has been named chair of the Chesapeake Executive Council, assuming responsibility for the Chesapeake Bay Program’s policy-setting committee from outgoing Virginia Governor Timothy Kaine.
During a meeting of the Executive Council in Arlington, Va., EPA Administrator Lisa Jackson promised to continue the Bay Program’s positive momentum and lead the regional partnership into a new era of progress and accountability as Executive Council chair.
“It’s an honor to chair the Executive Council at this moment of unprecedented opportunity,” Jackson said. “Chesapeake Bay communities have spent years calling for cleaner water and a healthier environment. We have a renewed opportunity to show them real progress.”
Administrator Jackson noted that 2009 was a historic year for the Chesapeake Bay restoration effort, with the states’ commitment to two-year milestones for implementing pollution controls and President Obama’s Executive Order on the Chesapeake Bay.
2010, however, could be a turning point for the Chesapeake Bay through the completion of the Chesapeake Bay TMDL and a new restoration strategy required by the Executive Order. The six states and District of Columbia will also receive $11.2 million in federal funding – more than double 2009 levels – to increase permitting, enforcement and other regulatory activities.
“Success in restoring the Chesapeake Bay and local waterways hinges on the collective effort of all stakeholders, and this partnership provides a vehicle for federal and state governments to collaborate and ultimately reach our common goals,” said Jackson, who also serves as chair of the Federal Leadership Committee established by the Executive Order.
Governor Kaine held the position of Executive Council chair since November 2008. His gubernatorial term ends this month.
"Last year, we charted a new, more effective course for improving the health of Bay waters by establishing critical two-year milestones that will serve as the foundation for future success," said Kaine. "I am pleased with what we've been able to accomplish by working together, and I have no doubt that Administrator Jackson will build on our progress in 2010."
As Governor of Virginia, Kaine permanently conserved nearly 400,000 acres of land, worked with Maryland to better protect the blue crab population, strengthened stormwater regulations, and launched climate change planning.
As chair of Executive Council, Kaine led the effort to create two-year milestones, which represented a fundamental shift in goal-setting, and worked with the White House on the Executive Order, the most significant federal action on the Chesapeake Bay in 25 years.

“The health of our Chesapeake Bay is critical to the environmental and economic future of the states that surround it and the people who enjoy it, and these regional partnerships have been invaluable to these efforts,” said Maryland Governor Martin O’Malley, past chair of the Executive Council. “Adding to these efforts the passion, partnership and authority of EPA Administrator Jackson will guide us through a new era of progress and accountability.”
“The Chesapeake Bay Commission looks forward to continuing the strong partnership we have established with the Bay Program and working closely with Administrator Jackson in finding new and innovative ways to clean our Bay and preserve this national treasure for generations yet to come,” said Chesapeake Bay Commission Chair, Virginia Delegate John A. Cosgrove.

Media Question and Answer Session (two parts)
Virginia has approved new stormwater rules that will help reduce polluted runoff – the fastest-growing source of pollution to the Chesapeake Bay – to the streams, creeks and rivers that feed the Bay.
The new rules will reduce by 38 percent the amount of phosphorus that flows from new development and redevelopment projects in the Chesapeake Bay watershed portion of Virginia – about 60 percent of the state. Developers would have to install runoff-reducing practices, such as retention ponds and rain gardens that allow more water to soak into the ground. These practices reduce the amount of rain water that runs off roads and parking lots, picking up pollutants on its way into storm drains and local waterways.
Because of extensive changes to the regulations originally proposed, an additional public comment period will take place from Oct. 26 to Nov. 25. The Virginia Soil and Water Conservation Board plans to put the rules into place on or around Dec. 9.
“I am confident that, once finally adopted and implemented, these regulations will provide real benefits to the quality of our waters across the state and bring us closer to the elusive goal of a restored Chesapeake Bay,” said Preston Bryant, Virginia’s secretary of natural resources.

A partnership between the James River Association, the U.S. Fish and Wildlife Service, the Corporate Wetlands Restoration Partnership and several other organizations has protected from erosion more than 500 acres of tidal freshwater marsh on Herring Creek in Charles City County, Virginia.
The newly protected marsh, known as Ducking Stool Point, is a spit of land located at the confluence of Herring Creek and the James River. According to the U.S. Fish and Wildlife Service, Ducking Stool Point provides important habitat for waterfowl, bald eagles, largemouth bass and a number of other birds and fish.
To protect the marsh from further erosion, the partnership installed an 1,825-foot-long structure of sloping stone between the marsh and the James River. Stabilizing Ducking Stool Point will help protect stream habitat for migratory and residential fish species, many of which are recreationally valuable to area residents. The project also protects bald eagles and other wildlife that nest and roost in the area.
The project was completed in November and unveiled at a ceremony this month.

In tiny Occoquan, Virginia, located just minutes away from bustling Interstate 95 in Prince William County, Germán and Renate Vanegas anticipate their upcoming fall Occoquan River cleanup with a concern that many other small nonprofits only ever dream of: they may have too many volunteers.
At a time when many popular environmental initiatives — such as minimizing backyard fertilizer use and implementing “smart growth” development — target white, middle-class residents, the family-run Friends of the Occoquan (FOTO) has instead directed its efforts toward the Hispanic community: a fast-growing segment of the Bay region's population that's often overlooked by environmental groups.
Using a combination of outreach, education and on-the-ground conservation, FOTO has successfully engaged Spanish-speaking residents throughout Northern Virginia in protecting their local river and becoming stewards of the Chesapeake Bay.
FOTO's work is concentrated on the Occoquan River, which splits Fairfax and Prince William counties and flows into the Potomac River.
“When we first moved here about seventeen or eighteen years ago, the river was so polluted,” said Renate. “We began cleaning up the small area in front of our property. About four years ago, we decided to get some help.”
“Some help” came in the form of about 100 community volunteers, who spent one Saturday removing trash from the banks of the river at four local parks. FOTO has since hosted two cleanups per year, attracting hundreds of volunteers to remove bicycles, mattresses, appliances, dozens of tires and several tons of debris from the river, which supplies drinking water to the area's growing population.
FOTO began concentrating on the Hispanic community after the Vanegases met with local park rangers, who had observed many Hispanic families leaving their trash on the ground. When the rangers would ask the families to pick up their trash, they found that many did not understand English.
It's not that Hispanic residents do not care about the environment, explains Renate, but that environmental awareness is not a part of many Hispanic cultures.
To help the local Spanish-speaking community understand the importance of picking up trash, FOTO created and installed bilingual signs at parks in the Occoquan River watershed. “NO LITTERING: Drains to River / NO BOTE BASURA: Va al Rio,” the signs read, with the international “no” symbol of a circle with a red slash over a picture of a person throwing trash into the water.
FOTO has also reached out to the area's Hispanic youths by speaking at local middle and high schools. The Vanegases hope that young people will grow up to respect the Occoquan River if they learn about its history, geography and importance to Northern Virginia's residents.
FOTO's outreach and education efforts have been met with measurable success. At their last cleanup, the Vanegases estimated that about 80 percent of the volunteers were Hispanic. Many of them were the same students the Vanegases spoke to at the local schools.
Last year, FOTO completed one of its largest projects to date when it helped produce a bilingual education video that teaches viewers about the link between human actions and the health of the Occoquan River and the Chesapeake Bay. “Saving Our Watersheds: Beyond the Occoquan,” has been shown on public access channels throughout Northern Virginia. FOTO is now working with other local networks so more people can learn about the importance of protecting the river.
The work has been difficult at times. But FOTO has managed to connect with a large and important part of the Bay watershed's population that may otherwise have been neglected.
As they prepare for October's cleanup — and the potential of having more volunteers than trash to pick up — the Vanegases look back on their mobilization efforts with enthusiasm.
“One thing we have learned over the years is that you have to be persistent,” said Germán.
“Yes,” Renate added with a smile. “Persistence is key.”
