Water quality modeling experts have announced a drop in estimated nutrient and sediment loads entering the Chesapeake Bay. Computer simulations show that pollution controls put in place between 2009 and 2015 have reduced the amount of nitrogen, phosphorus and sediment entering the Bay by eight, 20 and seven percent. During the 2014 to 2015 reporting period alone, these controls reduced nitrogen, phosphorus and sediment loads by three, three and four percent. Experts attribute this drop to significant reductions of nitrogen and phosphorus in the wastewater sector, reductions in the atmospheric deposition of nitrogen as a result of the Clean Air Act and the increased implementation of agricultural conservation practices. Improved reporting and enhanced crediting of these practices have also generated a more accurate picture of the pollution entering rivers and streams from this sector.
Excess nitrogen, phosphorus and sediment impair water quality: nutrients can fuel the growth of algae blooms that lead to low-oxygen “dead zones,” while sediment can block sunlight from reaching underwater grasses and suffocate shellfish. The pollution load estimates discussed here are one in a suite of tools used to track progress toward our clean water goals, which include the pollution-reducing commitments of the Chesapeake Bay Total Maximum Daily Load.
Nutrient reductions in the wastewater sector account for 41 percent of the estimated Bay-wide nitrogen reductions and 38 percent of the estimated Bay-wide phosphorus reductions that took place between 2014 and 2015. Indeed, many large municipal wastewater treatment plants are removing more nitrogen from effluent than it was previously thought technology would allow.
Our picture of agricultural best management practices has also changed: cover crops have seen improved reporting, conservation tillage has seen increased implementation and nutrient management plans have become associated with increased nutrient reductions. Improved reporting and enhanced crediting allow computer simulations to show a more accurate picture of the pollution entering rivers and streams from the agricultural sector.
By incorporating the best available data into our computer simulations, we gain a more accurate picture of pollution in the watershed. This gives us a better understanding of the actions that are needed to restore water quality in our work toward an environmentally and economically sustainable watershed.
With gleaming silos and an expansive field of grass that doubles as a concert venue, Brewery Ommegang cuts a scenic profile against the lush forested hills of bucolic Cooperstown, New York. But just across the road, a nondescript concrete building is dedicated to a brew of a different sort. You can’t see it from ground level, but climbing a set of metal stairs reveals a dark amber surface calmly bubbling, releasing a pungent but recognizable aroma.
“You can smell the beer,” says Ommegang brewery manager Joe Poliseno.
Standing directly above the 150,000-gallon aeration basin of Ommegang’s wastewater treatment plant does bring to mind the smell of skunked beer. It is the destination for a pipe that carries all the production waste from the brewery—municipal and human waste is handled differently. Like a miracle in reverse, this is where the leftovers of an alcoholic beverage are turned back into water.
While yeast is fundamental to brewing beer, different microorganisms play a central role in breaking down Ommegang’s liquid waste. The process removes almost all the nitrogen and phosphorus from the water leaving the plant, keeping excess nutrients out of the Susquehanna River and the Chesapeake Bay.
“Usually it's 99.9 percent removal [of nitrogen and phosphorus],” Poliseno says. “That's pretty amazing—we meet our regulations and far pass them.”
The fermentation that makes beer and other alcoholic beverages is an anaerobic process, meaning it has to occur in the absence of oxygen. The waste process, however, is aerobic. The large blowers deliver oxygen to an activated sludge made of living microorganisms. The sludge takes about eight days to cycle through the aeration basin’s membrane bioreactor that filters the wastewater.
The sludge is mostly bacteria but also tiny animals like rotifers and nematodes. As Poliseno describes it, he could be describing cattle rotated on fields of grass.
“All those hungry organisms will be brought right back to where the feed is so they can break down even faster, because they'll be super hungry at that point,” Poliseno says.
As the bacteria eat, they grow and reproduce. The excess sludge is pressed dry and harvested as a valuable biomass that farmers spread on their fields.
With all the work being done by microorganisms, most of the people power at the plant goes to lab analyses that keep the operation running smoothly.
“I was surprised once I got into it, how much science happens here,” says Ommegang publicity manager Allison Capozza. “Brewing itself is very much kind of a combination of cooking and science.”
Capozza says that Ommegang’s location was determined in part by the fact that it is the site of a former hops farm, and also by the quality of the aquifer it sits on, which Ommegang taps with three wells.
“It’s just the most perfect water you could hope for, for beer,” Capozza says, standing on the edge of the grass. “For us, from a business standpoint it’s a no-brainer that we do everything we can to protect the water, because beer is 90 to 95 percent water.”

Stormwater runoff, or rainfall that picks up pollutants as it flows across paved roads and parking lots, is the fastest growing source of pollution into the Chesapeake Bay. But urban farms may offer an innovative way to manage that polluted runoff, according to a report from American Rivers.
Green infrastructure—such as rain gardens, green roofs and porous pavement—uses soil and vegetation to help slow the flow of runoff and manage rainwater where it falls. These projects can also offer benefits like cleaner air, reduced energy use and a boost in property values. According to the report, urban farms can offer not only the typical benefits of green infrastructure projects, but also benefits like improved nutrition and increased access to green space.
The report includes a list of ten recommendations for promoting the use of urban farms to manage stormwater runoff, such as providing training and funding opportunities for farmers, identifying vacant lots that could be converted to farms and updating city zoning codes to allow for urban agriculture.
The report, Urban Farms: A Green Infrastructure Tool for the Chesapeake Bay, is available online.
At Endless Trails Farm in Hubbardsville, N.Y., Troy Bishopp is looking for cow pies.
“There’s a little bit there, but overall there isn’t a whole lot of manure,” he says, explaining to the farm's manager. “Every rotation we’re going to want more.”
Bishopp is a conservation specialist with New York’s Madison County Soil and Water Conservation District and the Upper Susquehanna Coalition, and among the services he provides is advice on how grassland farmers can get the most out of their pastures. With 30 years of experience, he has learned to pay attention to the subtleties that only come with walking out in a field and talking with farmers.
“I’m constantly looking, because wherever that cow manure lands is where there’s going to be more grass than not,” Bishopp says. This passion for grass has led to him being called the Grass Whisperer, a moniker first bestowed on him by his friend Dick Warner during a visit to Washington to educate congressional districts about grass-based agriculture in New York.
Bishopp has worked with Endless Trails Farm for about eight years, first to set up some conservation practices like stream buffers, then helping with fencing and offering rotational grazing advice. When he visits a farm, his tools are cheap—a plastic grazing stick helps him assess how many pounds of feed are in a pasture, and a reel of electrified tape lets him keep animals on and off sections of pasture, a practice he prescribed for Endless Trails.
“There was no real system of fencing or paddock rotation [on this farm]. And so usually in July and August there wasn’t a whole lot of grass here,” Bishopp says. “Implementing strategic fencing, water spots around the farm, water tubs, and then allowing the grass and the pastures to rest for a month or two, always made a lot of grass which actually sequestered any rain that came, which is huge up here.”
The water infiltration resulted in more grass for cattle at the farm, and also less runoff, including sediment and nutrients, running into streams and ultimately into the Chesapeake Bay. In 2011, the Madison County Soil and Water Conservation District named Endless Trails its Conservation Farm of the Year.
“Generally speaking, we want to retain our topsoil, have good water infiltration and keep the waters clean,” Bishopp says. “When you produce a lot of feed and you do those things that make you money, conservation comes right along with it.”

As the sun breaches the horizon in Easton, Maryland, the blanket of fog begins to dissipate, revealing the still waters of an 18-acre wetland and rows of organic vegetables. This is Cottingham Farm, the work of an environmental-lawyer-turned-farmer named Cleo Braver and a host of helping hands.
This 156-acre farm has undergone a variety of changes before arriving at its current state. The land was once used to grow wheat to feed Washington’s army. It then hosted peach orchards in the late 1800s and early 1900s. After the end of World War II, substantial changes in agriculture swept the nation—industrial monocrops, pesticides and fertilizers—and eventually made their way to what is now the Cottingham property. When Braver purchased the land in 1998, it was primarily used to grow corn.
Though Braver’s professional background is in the environmental field, she was unaware of the impact certain agricultural techniques—both on her own property and other area properties—were having on regional waterways. But after spending many evenings peering out at Goldsborough Neck Creek, which winds behind her house before meeting the Miles River and emptying into the Chesapeake Bay, she began noticing how the fish behaved strangely at the surface of the water. After some research, she learned about the creek’s poor water quality and how the heavy use of pesticides and fertilizers was partially responsible.
Braver’s interest in producing healthy food while minimizing her impact prompted her to make a change. By chance, she met Ned Gerber of Chesapeake Wildlife Heritage, who assisted with transforming the property by installing buffer strips to reduce sediment and nutrient runoff, replacing corn with organic vegetables and building a wetland housing 30 species of plants.
Gerber helped Braver utilize the Conservation Reserve Enhancement Program (CREP), a federal USDA Farm Bill program that supports the implementation of habitat on private lands. CREP covered 90 percent of the construction costs for the wetland, and the Maryland Department of Natural Resources picked up the remaining sum. Gerber and Chesapeake Wildlife Heritage continue to manage and maintain the wetland today.
But what Braver is perhaps most proud of on Cottingham is the evolution of the food production there and how it gives people greater access to healthy produce and meat. With the help of farm manager Jenn Djambazov and several employees, Braver now grows at least 50 different organic vegetables and raises pastured pigs. Organic matter in the property’s soil is slowly rebounding, and, to top it off, business is good. Cottingham sells produce through its CSA, as well as in local stores and restaurants.
Braver acknowledges the process has been a lot of work and has required time, expertise and funding from a range of parties. But she maintains that the transition to organic farming is more accessible than many people think, and she advocates for giving it a chance. “I’m not saying convert all of your feed corn to organic vegetables. I’m not saying that all,” she clarifies. With a slight smile at the corners of her mouth, she continues, “But try a piece of it. Take five acres out…”
It could make all the difference.

Animal agriculture programs in Delaware, Maryland and West Virginia have had varying degrees of success as they work toward meeting pollution-reduction goals for the Chesapeake Bay, according to evaluations released by the U.S. Environmental Protection Agency (EPA).
Under the Clean Water Act, the EPA periodically reviews state programs and policies related to water quality, and these reviews are typically not focused solely on animal agriculture. But the agency chose to conduct individual animal agriculture assessments for the six Bay states to ensure each state has the programs, policies and resources they need to achieve the goals of the Chesapeake Bay Total Maximum Daily Load (TMDL).
EPA found the states to be successful in certain areas: Maryland, for instance, was found to have a “robust and well-implemented state program.” But other aspects of the states' animal agriculture programs need further development—including improving data collection in Delaware and ensuring compliance with voluntary nutrient management plans in West Virginia.
Animal agriculture—such as poultry and livestock operations—can be a major source of pollution in the Bay. Excess nutrients and sediment have long impaired the estuary: nitrogen and phosphorous can fuel the growth of harmful algae blooms, while sediment can smother shellfish and block sunlight from reaching underwater plants. But practices like streamside fencing and proper management of animal manure can help prevent excess nutrients and sediment from reaching local waters.
The reports are available on the EPA’s Chesapeake Bay TMDL website.
It’s an overcast summer morning in Berkeley County, West Virginia, and Todd Butler has parked his pick-up truck atop one of the many hills that roll across his property. He points to the ridge of a nearby mountain peak, where the dense, forested tree line is broken by a small gap. “I’m sitting in my house, and I can see this mountain from there,” Butler recalls. “I never will forget the very first morning I sat there, and I saw a light on top of that mountain, and I thought, ‘What is that?’ And it turns out, they’d built a house up there.”
As the fourth-generation owner of Butler Farms, Butler has been witness to plenty of changes over the years: a decline in the number of neighboring farms, a rise in residential development, a technology boom for farming equipment. And while some features have remained the same—the original farmhouse, barn and cattle gates are still standing—much of the farm’s operation is dramatically different from when Butler’s great-grandfather bought the land in 1919. Almost a century later, the 200-acre family dairy farm has grown to more than 1,000 acres, home to beef cattle, an apple orchard and a bird and deer hunting preserve.
Over the years, Butler and his father, Bill, have transformed their property into one of the top conservation farms in the Mountain State. A variety of practices—from streamside fencing to cover crops—help to reduce runoff and promote water quality. Cattle drink out of troughs rather than straight from streams, and their feed wagons are continuously moved to different locations to prevent a single area from getting trampled or polluted with manure. The farm’s 72 apple orchard plots are farmed in strips; the land between each row of trees is left untouched to help slow the flow of water and prevent soil from washing away.
Sustainable pest management practices have made the land of Butler Farms a haven for insects, birds and other wildlife. Pollinator-friendly native flowers and grasses border the fields. Patches of sorghum, an annual grass that produces bright red berries, will feed birds and deer through the winter. When Butler was younger, he remembers entire fields being sprayed with herbicides, pesticides and other chemicals. Now, he says, “we don’t use near the chemicals that we used to. Everything used to be in quarts or gallons; now we’re down to ounces.”
A new report from the Delmarva Land and Litter Work Group—a partnership of poultry and grain producers, conservation partners, academic experts and other stakeholders—outlines the group’s recommendations for reducing nutrient pollution related to poultry manure, or “litter,” on the Eastern Shore of the Chesapeake Bay.
Known as the Delmarva Peninsula, the land to the east of the Bay includes parts of western Delaware and eastern Maryland and Virginia. It is also responsible for a disproportionate amount of the excess nitrogen and phosphorus polluting the estuary, according to a report from the U.S. Geological Survey (USGS) released earlier this year. But the Delmarva Land and Litter Work Group is committed to improving the relationship between agriculture and Bay health, encouraging responsible nutrient management and promoting alternative uses for manure and poultry litter.
To support the group’s vision of a healthy and productive Chesapeake Bay, the report recommends developing action plans for the research, implementation, funding and coordination of regulations for nutrient management programs and technologies. Along with the report, members of the work group announced the launch of the Delmarva Land and Litter Challenge, an initiative to unite stakeholder groups and take the lead on the responsible use of manure and poultry litter.
Livestock manure and poultry litter are often applied to farmland as a form of fertilizer, providing crops with the nutrients they need to grow. When more litter is applied to the land than is needed by crops, nutrients can build up in the environment. Eventually, these nutrients flow into streams, rivers and the Chesapeake Bay, where they can fuel the growth of harmful algae blooms that block sunlight and create low-oxygen “dead zones” that suffocate marine life.
Under the clean water goals of the Chesapeake Bay Watershed Agreement, which encompasses the Chesapeake Bay Total Maximum Daily Load (TMDL), Bay Program partners are working with farmers across the watershed to reduce the amount of nutrients entering local waterways.
The report, New Approaches to Poultry Litter Management in the Chesapeake Bay Watershed: Win-Win Pathways for Agriculture and the Bay, is available online.
Faith plays an influential role in the lives of billions of people in the world, with about 84 percent identifying with a religious group. As Ramadan, a month-long ritual focused on self-purification and refocusing attention to faith, comes to an end for roughly 1.6 billion Muslims around the world, it is a good time to reflect on the intersection between conviction and nature.
Green Muslims, a Washington, D.C., based organization with the mission of helping their community live in the environmental spirit of Islam, began with a conversation between a group of friends about how to ‘green’ their Ramadan. At first they took small measures, like switching to reusable plates and having zero-trash iftars, or evening meals, when they could break their fasts. Those simple actions set off a chain reaction of stewardship within the community that led to the formal establishment of Green Muslims as a volunteer organization in 2007.
The nonprofit works with a number of different Muslim communities in the D.C. area, but serves as a national resource for those across the country that are looking to tie their faith back to the natural world. “There is really a passion and a yearning for learning more about what our tradition is amongst the Muslim community everywhere, and we hope to provide those resources and incubate that energy to take it to the next level,” said Colin Christopher, Executive Director of Green Muslims.
With many youths spending an increasing amount of time indoors, exposure to and connections with the natural world are lost, often times leading to rises in health problems like allergies and obesity. In a push to alleviate nature deficit disorder, Green Muslims launched the ‘Our Deen is Green’ Youth Outdoor Education Program this year. The program offers a wide range of field trips to places like the Chesapeake Bay, farms and conserved lands to demonstrate real life examples of how Islam and the environment are intertwined.
Each trip offers themed lessons that cover subjects such as, water, food waste and renewable energy. The goal of the program is to reconnect the participants with outdoor spaces and encourage healthy behavior changes, like wiser food choices and increased awareness about human impacts on the planet. “In Islam, we understand that God has an amount of trust in us as Khalifas, or stewards of the Earth. We really see our responsibility as people who need to conserve and protect the natural environment; we are called to do so, it’s our responsibility,” said Christopher.
The final trip of the year was to Rock Creek Park in Washington, D.C., where the kids toured the historic Peirce Mill and learned how the Earth’s natural processes like water flow and wind create energy that can be harnessed with minimal negative impacts to the environment. Prior to touring the mill, all eight kids sat contently in a circle making windmills out of paper and pencils while discussing where their energy comes from. “Why are we always talking about water?” asks a young boy. “Because we are made of water,” replies Christopher. A look of awe falls over the children’s faces. The importance of water is a theme that weaves through all lessons taught during the program.
The Qur’an has hundreds of verses that talk about water, animals, wind and the sun, and Sharia, or Islamic law, directly translates into ‘the pathway to the water source’—meaning that protecting water is of utmost importance in the tradition of Islam. “Every part of our natural environment is integral to the greater whole. In Islam, we talk about, if you have one limb that is unhealthy then the entire body is unhealthy and sick. So, the Chesapeake Bay is a really integral part of that entire ecosystem and we can’t afford to neglect the Bay or other parts of our ecosystem," explained Christopher.
Although the organization aims to spread awareness about the link between Islam and the environment, Christopher believes that diversity is the backbone of the Muslim community and welcomes anyone, regardless of faith, to volunteer and participate in Green Muslim events. “I think that the challenges we face relate to education. There is a lot of misinformation about Islam and what Islam is,” noted Christopher. “We are trying to bring back the teachings of our traditions within our community and explain that conservation, moderation and love for creation are core components of our tradition.”

Rich soil and a mild climate have made the lands of Lancaster County, Pennsylvania, a haven for agriculture. Thousands of farms—more than any other county in the state—dot the landscape of gently rolling countryside. Traveling through the region, the fields and fences, barns and silos can begin to blur together. But venture onto the land itself, and each tract of farmland tells a unique story. For Oregon Dairy Farm in the heart of Lancaster County, the story is one of family, conservation and community.
A family-run operation, Oregon Dairy Farm is managed by George Hurst, his son Chad and his daughter and son-in-law Maria and Tim Forry. Hurst also co-owns the nearby market, restaurant and ice cream parlor with his brothers. He is the second-generation owner of the land, after his father bought the farm in the early 1950s. “I grew up here and bought the farm, bought the house where I grew up,” said Hurst. “Now my daughter, Maria, is living in that same house.”
Pennsylvania is second in the nation for number of dairy farms, outranking every state except Wisconsin. And that number continues to grow: in 2014, Pennsylvania was the only state in which the number of dairy farms increased. Though this may be good news for ice cream lovers, it can sometimes be difficult to reconcile agricultural growth with the health of the Chesapeake Bay, as agriculture is the single largest source of nutrient and sediment pollution entering the estuary. But for the Hurst family, protecting the Bay is an important part of the way they run their farm.
Two decades ago, the Hurst family took a visit to the Chesapeake Bay. What they saw—polluted waters and their damaging effects on local fishermen—troubled them. “When I took that tour, I knew we had to do what we can here [at Oregon Dairy Farm] to make sure we’re not polluting the Bay,” Hurst recalled. “That’s when we became even more intentional with the practices we have in place here.”
Those practices include a variety of “best management practices,” or BMPs—conservation methods that can help curb nutrients and sediment from running off agricultural land and into rivers, streams and the Bay. To protect the health of waters running through their land, the Hurst family practices no-till farming, uses cover crops, plants trees and shrubs to prevent streambank erosion and has installed fencing to keep livestock out of waterways.
As home to 500 cows, one of the farm’s biggest challenges was figuring out how to manage all the animal waste. “Because we’re a dairy, there’s lots of manure,” Hurst explained. According to estimates from the U.S. Environmental Protection Agency (EPA), livestock waste accounts for 19 percent of the nitrogen and 26 percent of the phosphorous entering the Bay. These excess nutrients can fuel the growth of algae blooms that block sunlight from reaching underwater grasses and, during decomposition, rob the water of oxygen that plants and animals need to survive.
To avoid nutrient runoff, Hurst puts as much of this waste to use as possible. A methane digester collects and heats the manure, and the resulting methane gas powers a generator that produces more than enough electricity to run the farm.
After traveling through the digester, solid and liquid wastes are separated. Solid waste can be dried and used as livestock bedding or transported to the on-site composting facility. Three large hoop buildings house the compost piles, which will eventually be sold wholesale to landscapers or in Oregon Dairy’s retail lawn and garden store. Liquid waste flows to the lagoon, which holds about an eight month supply, allowing it to be applied to the land when the fields need it and will absorb it. “We make sure we aren’t putting more manure on than what will stay in place, and no more than what the soil needs or what will be taken up by the crops,” said Hurst. These innovative waste practices helped the farm win a U.S. Dairy Sustainability Award in 2015.
Since the 1980s, outside dairy farmers, school field trips and other community members have been welcome to tour—and learn from—the farm. School tours bring nearly 2,000 student visitors each year, and Family Farm Days events can draw upwards of 15,000 people a year to the farm. More than just a way of life, Hurst and his family see their farm as a way to teach others about how they care for their land.
“Our passion and vision is to help people understand where their food comes from,” said Hurst. “That’s where [the farm tours] originated and that’s really why we do what we do.”

Preventing livestock from entering streams could improve the health of both local waterways and the animals themselves, according to a new report from the Chesapeake Bay Commission.
When hoofed farm animals—such as cattle, horses, pigs, sheep and goats—have clear access to streams, they trample and erode the banks and bottoms of waterways, freeing sediment and nutrients to flow downstream to the Bay. Animal waste contributes additional nutrient pollution, as well as bacteria that can cause human health concerns.
“Livestock exclusion” is an agricultural best management practice (BMP) that uses fences, streamside buffers and alternative water sources to draw animals away from streams and wetlands. The practice benefits not only water quality but the health of the animals themselves: in operations that have installed fences along streams, farmers have reported decreases in injuries and disease in their herds. In the report, the Bay Commission details the benefits of livestock exclusion; describes current efforts throughout its member states of Maryland, Pennsylvania and Virginia; and looks at factors affecting the widespread implementation of these practices.
By lowering the amount of sediment and nutrients flowing to the Bay, practices like livestock exclusion help meet the clean water goals of the Chesapeake Bay Watershed Agreement, which encompasses the Chesapeake Bay Total Maximum Daily Load (TMDL).
The report, Healthy Livestock, Healthy Streams: Policy Actions to Promote Livestock Stream Exclusion, is available through the Chesapeake Bay Commission website.
While pollution controls put in place over the last five years have lowered the amount of nutrients and sediment entering the nation’s largest estuary, new data show that agricultural sources have sent more nitrogen and sediment into the Bay since 2007 than previously thought.
Excess nitrogen, phosphorus and sediment can impair water quality: nitrogen and phosphorus can fuel the growth of harmful algae blooms, while sediment can suffocate shellfish and block sunlight from reaching underwater plants.
Each year, the seven watershed jurisdictions report the steps they have taken to lower the nutrients and sediment entering rivers and streams. Bay Program experts run this information through a suite of computer simulations, which generate pollution load estimates that show us how far our partners have come toward meeting the Bay’s “pollution diet.” When bolstered with new data on population size, land use and agricultural commodities, these simulations show a drop in pollution since 2009—including a six percent drop in nitrogen, an 18 percent drop in phosphorus and a 4 percent drop in sediment—but a two percent rise in nitrogen and sediment loads between 2013 and 2014.
A shift in agricultural commodities could explain this rise in nitrogen and sediment loads. According to data from the U.S. Department of Agriculture’s Census of Agriculture, several states have seen a surge in corn plantings since 2007. Because corn requires nitrogen-rich fertilizer that can leach off the ground and into local waterways, more corn plantings led to more nitrogen loadings than anticipated when pollution targets and reduction milestones were set.
The Bay Program uses the best possible data and information to track our progress toward restoring water quality. By incorporating new data into our computer simulations and pollution load estimates, we are allowed a more accurate picture of pollution in the watershed and a better understanding of the actions that are needed to reach our clean water goals. Because these computer simulations generate pollution load estimates using long-term average weather conditions, it’s possible for these estimates to differ from those that are based on water quality monitoring data; the latter can vary with the amount of rainfall in a given year.
“Each year, we employ the most current data and up-to-date science [to] offer the highest quality information to the public on pollution reductions resulting from Chesapeake Bay Program partners’ continued efforts. While we… have a lot of work to do… we are making steady progress toward meeting water quality goals,” said Bay Program Director Nick DiPasquale in a media release.
These pollution load estimates are just one in a suite of tools the U.S. Environmental Protection Agency (EPA) uses to evaluate whether jurisdictions are on track to meet the Total Maximum Daily Load (TMDL) and its two-year milestone commitments. The EPA also considers data and information on best management practice implementation, best management practice effectiveness and jurisdictions’ progress toward putting programs in place to achieve pollution cuts. It is expected to release interim assessments of jurisdictions’ work in May and conduct the next full two-year assessment in 2016.
Nutrients flowing from the Chesapeake Bay’s Eastern Shore make up a disproportionate amount of the excess nitrogen and phosphorus polluting the estuary, according to a recent report from the U.S. Geological Survey (USGS).
The land to the east of the Bay, known as the Delmarva Peninsula, includes parts of western Delaware and eastern Maryland and Virginia, and makes up just seven percent of the watershed’s total land area. But per square mile, Delmarva receives nearly twice as much nitrogen and phosphorus as other areas in the region, leading to degraded water quality in the rivers, streams and groundwater that flow to the Bay. These nutrients can fuel the growth of harmful algae blooms that block sunlight and create low-oxygen areas, or “dead zones,” that suffocate marine life.
“On the Eastern Shore, the concentrations of nitrogen in groundwater, and nitrogen and phosphorus in surface waters, are well above natural levels and are among the highest in the nation,” said Scott Ator, a USGS hydrologist and co-author of the study.
According to the report, agricultural production—including fertilizer and manure applied to cropland—accounts for more than 90 percent of the nutrients reaching the lands of the Eastern Shore. When more fertilizer and manure is applied to the land than is needed by crops, nitrogen builds up in the groundwater and phosphorus builds up in the soil, and these nutrients eventually move into streams that flow to the Chesapeake Bay.
Under the clean water goals in the new Chesapeake Bay Watershed Agreement, which encompasses the Chesapeake Bay Total Maximum Daily Load (TMDL), Chesapeake Bay Program partners are working to reduce the amount of nutrients entering local waterways—including working with farmers across the watershed to implement “best management practices” or “BMPs” that curb agricultural runoff. Findings from the USGS report will help improve the placement of these practices to reduce the nutrient pollution reaching groundwater, streams and the Bay.
When thinking of wine, Maryland may not be the first state that comes to mind, but for the Deford family, the artful pairing of responsible land management and master craftsmanship at Boordy Vineyards has put the Free State on the wine aficionado map.
Nestled in the rolling countryside of Long Green Valley in Hyde, Maryland, a mere 30 minutes outside of Baltimore, the 240-acre property provides solace to visitors, melting away the stressors of daily life with views of rich vegetation, historic farmland and 25 acres of intricately arranged rows of grapevines.
The family strives to develop a lasting connection with the community and welcomes visitors year-round by regularly hosting events. “Everything we do here has an educational component to it because wineries are unusual in Maryland, farming is increasingly rare and we are constantly competing with other views of how the countryside around Baltimore County should be managed,” said Robert Deford, President and owner of Boordy. “We really want farming to succeed here.”
To Deford, a twelfth generation Marylander and the fourth generation to be raised on the farm, success and sustainability go hand-in-hand. In 2000, the family placed the property under permanent conservation easement through Maryland Environmental Trust, allowing the farm to proceed without having to compete with development money by taking the option to sell the land to developers off the table. “We look at land not as an empty resource to be built on, but as something to be tended to and taken care of. For me, sustainability means the ability to realize the dream of continuing to live and work here,” explained Deford.
The 25 full-time and 75 part-time employees have adopted the Defords’ mission of sustainability and assist in the efforts to be as efficient as possible. “If we are not sustainable by definition, we are going to go out of business at some point. The land is what sustains us, so if we treat it badly the system is going to crash,” said Deford.
A number of best management practices have been implemented on the vineyard to reduce the establishment’s energy demands and impact on the environment. Staff hand-pick the fruit – avoiding the use of machinery – to ensure only the highest-quality grapes end up in the wine; the rest are left for wildlife, like birds, to scavenge. Grass grows freely in between the vines to stabilize the soil and mitigate runoff of sediment into the adjacent stream on the property. Additionally, all stems and pomace are composted post-production and returned to the fields as fertilizer.
A wetland was created at the head of the stream to catch any residual runoff before it enters the waterway, eventually making its way to the Gunpowder River and ultimately the Chesapeake Bay. The wetland serves not only as a pollution buffer but also as habitat to countless species of wildlife such as beavers, ducks, white-tailed deer and raptors. “Another thing that is great is we have excluded all livestock [from the stream], and it is astounding the fish people are finding down there, especially the American eel. I think it is a great model for what can be done to a stream that was really in distress,” said Deford.
The family is mindful of their greenhouse gas emissions and works to reduce their outputs by using the carbon dioxide created in the fermentation process to stir their red wine tanks. The carbon dioxide is collected, builds up and eventually erupts through the tank – stirring the wine and saving electricity. “There is an interesting concern over the fact that when you make wine you emit carbon dioxide into the atmosphere; however, what I always point out to people is that just up the hill is the other end of it – those vines take in carbon dioxide, so really it’s just a cycle,” notes Deford.
Helpful for Boordy has been the advent of the local food movement, a developing culture focused around locally-produced food and the process of getting it from the farm to the table. With the movement comes a growing consumer demand to meet the farmer and know where food comes from. “This isn’t just liquid in a bottle,” said Deford. “A lot more goes into it.”

Nestled next to Patuxent River State Park in Laytonsville, Maryland, are the 220 rolling, vegetation-rich acres of Waredaca horse farm. Husband and wife Robert and Gretchen Butts are the second generation to manage the family farm since Robert’s parents purchased the property in 1953. To them, Waredaca is more than just a business: it is their home.
The farm has evolved from a summer camp to a boarding stable for more than 80 horses, 30 of which are directly owned by Waredaca; recreational and competitive riders board the rest. The farm continues to host a youth summer camp, hold eventing competitions and offer year-round riding lessons. “To be able to make a living doing things you love—and to do it at home—is the best. This place is my life, and that’s pretty special,” Robert said.
The Butts’ connection to their land has sparked a deep sense of environmental stewardship within their family. “We’ve been here our whole lives, and plan on being here a long time. I think for a large portion of the agricultural community, that’s the case. Many have been motivated conservationists for years,” Robert explained.
A prominent part of Maryland’s environmental efforts to conserve farmland has included the equine community. “In recent years, certainly the state and Montgomery County have clarified in legislation that horses are a part of agriculture and therefore the services and outreach pertain to them,” said Robert. “Outreach to the equine community has been particularly important to [increasing] participation [in restoration initiatives].”
The Maryland Horse Council has been a strong partner with the state’s Farm Stewardship Certification and Assessment Program (FSCAP), which certifies agricultural stewards throughout the state. Since its development in 2010, FSCAP, administered by the Maryland Association of Soil Conservation Districts (MASCD), has conducted 131 reviews on 108 farms and certified 91 agricultural conservation stewards protecting 27,000 acres in 16 counties. The Maryland Horse Council has helped FSCAP certify 20 horse farms.
According to the state, any farm with more than eight “animal units”—normally defined as one mature cow weighing about 1,000 pounds and her suckling calf—is required to follow a nutrient management plan to ensure that excess manure is properly disposed of. Assessors from FSCAP are trained by the Maryland Department of Agriculture to review nutrient management plans with the same attention to detail provided by official inspectors. Assessors also inspect other “best management practices” (BMPs), which reduce pollution and improve habitat on farmland. When certified, each steward gets his or her own webpage on the FSCAP website and the landowner receives a large sign to place on their property, advertising their environmental stewardship.
“The program was created in order to provide some positive recognition for farmers that are doing a great job [caring for the land], in light of what seems like fairly constant criticism about agriculture’s role in polluting the Chesapeake Bay,” said FSCAP Project Leader Gerald Talbert. “We carefully gathered core partners for this program because we wanted both the agricultural and the environmental communities to be involved.”
"Many stewards feel that certification means more than just personal recognition; it’s also good for business,especially with farms that deal directly with the public” Talbert said. “ So far, we’ve provided 91 signs, but there are 133 signs displayed.
By working together, Robert and Gerald were able to identify and address a streamside fencing issue that thwarted Waredaca’s certification efforts. The problem has since been fixed and the farm has been certified.
The Butts follow a nutrient management plan, composting their manure and spreading it on their fields to encourage rich soil and healthy pastures. They have also put a number of BMPs in place: a manure storage facility, a spring-fed water tank and stream-side buffers with fencing to keep horses out of streams, thereby keeping the surrounding creeks and streams clean.
The Butts also practice rotational grazing. Strategically moving livestock to fresh pastures can allow previously grazed fields to regenerate, and is a preferred practice for fighting overgrazing. But many farmers do not have the space to rotate their grazing pastures, leading to field erosion and the sedimentation of rivers, streams and the Bay.
“We are very blessed to have a lot of room where the horses can roam,” Robert said. “Lack of space can be a limiting factor for many [horse-owners]. Overgrazing is a very common thing in the horse business, and will be hard to eliminate completely because of the way horses eat. Cows don’t eat the grass all the way down to the ground, but horses do,” he explained.
Through the efforts of programs like FSCAP and the willingness of farmers like the Butts to sign on to voluntary conservation programs, stewardship certification programs are gaining traction among the agricultural community. “Part of the effort here is not just to recognize those folks that have already done a great job, but to also provide incentive for someone to step up and put those one or two BMPs in place that they may have been missing to meet the standard,” said Talbert.

Think of a food, any food. It could be what you had for breakfast, or something you’ve been craving. Once you have an image in your mind, imagine what that snack would look like without the existence of fruits, vegetables or grains. Would it completely disappear? Would only a portion remain? Now ask yourself, “What is the common link—the necessary life source—behind the production of our food?”
The answer lies in the simple act of pollination. It is nearly impossible to think of something within our diet that can exist without it. Pollination, or the transfer of pollen between like species of flowers by wind or wildlife, leads to the formation of healthy fruit and seeds. It is estimated that nearly one-third of all plants and plant products consumed by humans depend on bee pollination alone.
Educators at Arlington Echo Outdoor Education Center in Millersville, Maryland, understand this fact and work to teach others about the important role that pollinators—like bees, butterflies and bats—play in our ecosystem. For the past 17 years, the center has partnered with the Anne Arundel Beekeepers Association (AABA) to provide a home for more than 80,000 honeybees each year. When needed, AABA donates bees to Arlington Echo to replenish the center’s four outdoor bee boxes and two indoor observation hives. While the outdoor apiary is used for ecological purposes—providing habitat for the bees—the observation hives are used to teach children and adults alike about insect anatomy and life cycles, pollinator survival, community roles and math.
While it started as a recreation center, Arlington Echo quickly evolved to support authentic, hands-on learning. Arlington Echo Outdoor Education Center is part of Anne Arundel County Public Schools and has been for 45 years. In fact, it is visited by every fourth grader in the county. “Education facilitates change,” said Sheen Goldberg, Teacher Specialist at Arlington Echo. The volume of students they reach each year provides a valuable opportunity to plant the seed of environmental awareness in many young minds. Here, people learn to make the connection between pollinators and the food they eat.
“One of the major issues we face today… is a lack of knowledge about the environment and where things come from,” said Melanie Parker, Coordinator of Arlington Echo’s Environmental Literacy and Outdoor Education Department. “[Food] doesn’t come from the grocery store. And it’s not just our kids [who are unaware]. Sometimes, it’s parents. Sometimes, generations don’t have that connection with the land and nature. There’s not that experience or exposure. All people see is that chicken comes in a package and isn’t an animal that’s running around on the ground. There is a detachment to where our stuff comes from.”
Spreading knowledge and linking people to their natural environment is a vital part of Arlington Echo’s mission. By connecting the dots between healthy pollinators and a healthy environment, they hope to incite positive change and help pollinators overcome the challenges they face. Population growth and development have encroached on pollinator habitat; chemical contaminants harm their health; and both native and invasive pests, parasites and diseases threaten populations.
“Right now, pesticides are a really big deal. Bees are going through something that we are calling Colony Collapse Disorder because we don’t actually know what causes it,” said Heather Calabrese, Program Assistant at Arlington Echo. “There is some research that points to a class of insecticides called neonicotinoids. It’s interesting how it, and many other pesticides, work. It doesn’t actually kill the animal right away. It effects the nervous system, disorienting it, [the animal] stops cleaning itself, eating, feeding other animals, and then it starves to death or dies of disease.”
Although honeybees, like those kept at Arlington Echo, are not native to North America, they are not considered invasive. Instead, they are considered an important part of our natural ecosystem, and their decline is directly linked to habitat loss. Development fragments wildlife habitat and pushes native species out. “Because of development, we lose native plant populations. If there is not enough food for our pollinators because we have built on their habitat, then we won’t have the native pollinators,” Parker explained.
Over the past 60 years, managed bee populations have declined from 6 million to 2.5 million, an alarming number that has sparked many states and organizations to offer financial and tax incentives to encourage people to keep bees.
Parker, Goldberg and Calabrese are all enthusiastic about keeping bees and claim that once you start, you can’t help but become fascinated by the social complexities of the critters. “You can put as much or as little work into maintaining the hive as you would like,” said Goldberg. “The bees are clean, hardworking and good at taking care of the hive for the most part.”
The educators at Arlington Echo stress the importance of making connections between the natural world and human health. Many of the things that harm pollinators also pose a threat to humans, water and other wildlife. “There is the developmental part of… pollinator population decline, but also the pesticide use,” Parker said. “Those pesticides end up in our waterways. You know, everything is connected. You pull one string and the rest unravels. So, even though it seems like a small piece, it is part of a bigger issue.”

Scientists have found intersex fish in three Pennsylvania river basins, indicating hormone-disrupting chemicals are more widespread in the Chesapeake Bay watershed than once thought.

Intersex conditions occur when pesticides, pharmaceuticals or other chemicals disrupt the hormonal systems of an animal, leading to the presence of both male and female characteristics. The presence of intersex conditions in fish, frogs and other species is linked to land use, as the chemicals that lead to these conditions often enter rivers and streams through agricultural runoff or wastewater.
Previous samplings of fish in the region have found intersex conditions in the Potomac, Shenandoah and Susquehanna rivers, as well as lakes and ponds on the Delmarva Peninsula. On samplings conducted at 16 sites between 2007 and 2010, researchers with the U.S. Geological Survey (USGS) found intersex fish in the Susquehanna, Delaware and Ohio river basins.
According to the USGS, freshwater fish called white suckers from sample sites in the Delaware and Susquehanna river basins had a yolk precursor in their blood. Male smallmouth bass from all sample sites had immature eggs in their testes. The prevalence of intersex fish was highest in the Susquehanna river basin, which researchers attribute to the higher rate of farms—and related herbicides, pesticides and hormone-containing manure—in the area. While scientists found no relationship between the number of wastewater treatment plants in an area and the prevalence of immature eggs in fish, the severity of intersex conditions did rise at sites downstream from wastewater discharge points.
“The sources of estrogenic chemicals are most likely complex mixtures from both agricultural sources, such as animal wastes, pesticides and herbicides, and human sources from wastewater treatment plant effluent and other sewer discharges,” said fish biologist Vicki Blazer in a media release.
Reducing runoff from farmland has lowered pollution in Maryland, Virginia and Pennsylvania waters, indicating a boost in on-farm best management practices could lead to improved water quality in the Chesapeake Bay.
In a report released earlier this year, researchers with the Chesapeake Bay Program, the University of Maryland Center for Environmental Science (UMCES) and the U.S. Geological Survey (USGS) use case studies to show that planting cover crops, managing manure and excluding cattle from rivers and streams can lower nutrient concentrations and, in some cases, sediment loads in nearby waters.
Excess nutrients and sediment have long impaired the Bay: nitrogen and phosphorous can fuel the growth of algae blooms and lead to low-oxygen dead zones that suffocate marine life, while sediment can cloud the water and suffocate shellfish. In New Insights: Science-based evidence of water quality improvements, challenges and opportunities in the Chesapeake, scientists make clear that putting nutrient- and sediment-reducing practices in place on farms can improve water quality and aquatic habitat in as little as one to six years.
Planting winter cover crops on farm fields in the Wye River basin, for instance, lowered the amount of nutrients leaching into local groundwater, while planting cover crops and exporting nutrient-rich rich poultry litter in the upper Pocomoke River watershed lowered the amount of nitrogen and phosphorous in the Eastern Shore waterway. In addition, several studies in Maryland, Virginia and Pennsylvania showed that when cattle were excluded from streams, plant growth rebounded, nutrient and sediment levels declined and stream habitat and bank stability improved.

Earlier this week, U.S. Department of Agriculture Secretary Tom Vilsack named the Bay watershed one of eight “critical conservation areas” under the new Farm Bill’s Regional Conservation Partnership Program, which will bring farmers and watershed organizations together to earn funds for soil and water conservation.
In February 2014, President Barack Obama signed the Agricultural Act of 2014—better known as the Farm Bill—into law. Like its predecessors, this new Farm Bill funds a wide array of federal commodity, forestry, social, trade and conservation programs. Altogether, the Farm Bill authorizes nearly $1 trillion in federal spending over the next 10 years, with roughly $57 billion authorized for conservation and preservation programs. But how will the law affect conservation practices in the Chesapeake Bay watershed?
The 2008 Farm Bill established the Chesapeake Bay Watershed Initiative (CBWI), which dedicated $188 million to conservation practices in the Bay region. The 2014 Farm Bill eliminates the regional programs established under previous Farm Bills, including the CBWI and the Great Lakes Basin program, and consolidates 23 national conservation programs into 13. For the Bay, the most notable of these 13 programs is an innovative new initiative called the Regional Conservation Partnership Program (RCPP). The RCPP allows qualified organizations to request funds on behalf of farmers from the U.S. Department of Agriculture’s Natural Resources Conservation Service (NRCS), which oversees most of the conservation programs under the Farm Bill. These organizations then work with farmers to leverage those funds toward the implementation of conservation practices, from structures that store animal manure to fences that exclude livestock from streams. This approach not only leverages the federal cost-share funds for farmers, but it allows them to work with a wider range of non-federal partners and experts. This increases the number of “boots on the ground” engaged in conservation work, fostering new partnerships between farmers and organizations that want to help.
But how much money is available under the RCPP? The RCPP will receive up to $100 million per year, plus an additional seven percent of the funds and acres available under “covered programs.” Covered programs include the Environmental Quality Incentives Program (EQIP), the Conservation Stewardship Program (CSP), the Agricultural Conservation Easement Program (ACEP) and the Healthy Forests Reserve Program (HFRP). However, these funds are for the entire RCPP.
The NRCS will award the bulk of this money through a competitive application process at the national and state levels. The remaining 35 percent of the funds will be awarded in a similar competitive process within “critical conservation areas.” The Secretary of Agriculture can name only eight of these areas. Based on the law’s criteria, the Bay watershed will be a strong candidate, but the eight areas are yet to be determined by the USDA.
The NRCS is currently developing policies and guidelines to carry out the conservation programs under the new Farm Bill, so stakeholders should keep an eye out for announcements, workshops and other events that will explain the new programs and processes in more detail. The RCPP is a major innovation for conservation policy, but it will require increased collaboration between farmers, watershed organizations and agricultural groups to earn funds through competition.
On a blue bird day in Church Creek, Maryland, a white pickup truck bounces down a dirt driveway, splashing through fresh mud puddles and leaving ripples in its wake. The low whirring of female Northern pintail ducks in the middle of their courtship is exuberant, and there is excitement in the air – it is almost time for the birds to make their long migration north.
The truck rounds a bend and hundreds of waterfowl take flight, seeking solace in the nearby Honga River. Landowner Jerry Harris steps out of the truck, his two hunting dogs, Bo and Maddie, in tow. Jerry has owned Mallard Haven River Farm for nearly 20 years and has transformed it from an open pasture to an ideal stopover site for thousands of waterfowl migrating along the Atlantic Flyway.
Harris recounts purchasing the farm as an open pasture with a ditch down the center in the late ‘90s. Initially, he battled saltwater intrusion and high-tide floods of the Chesapeake Bay. His solution involved closing off the connection between the ditch and the Bay and creating a freshwater storage area that can now hold up to 6.5 million gallons of water. With financial assistance from the state of Maryland, Ducks Unlimited and North American Wetlands Conservation Act Grants (NAWCA), he built berms to create a series of separate water impoundments for use by waterfowl across 80 acres of the 230-acre farm.
Harris has hired two full-time employees to help maintain the property. “We’ve tried to do everything to improve the efficiency of our work,” Harris said. “We have pipes in all the impoundments that lead to a main water storage ditch, so we can connect our portable pumps right to the pipes and drive the water wherever we would like. If we’re irrigating this field during a dry period we don’t have to hook hoses up or anything.”
Because his land is privately owned, Harris has the freedom to experiment with unconventional conservation practices. His latest endeavor? Moist soils management, or the slow draw down of water from the impoundments to foster the growth of wetland plants like smartweed, fall panicum and fox tail. “As the water gradually comes down, it will support different kinds of weeds, and if you are good enough at it you can have a whole platter of foods that fulfill the ducks’ dietary needs,” Harris said. Moist soils management is good for the wildlife and the farmer: it cuts fertilizer use, and mechanical tilling is only needed about once every five years.
In the past, Harris grew corn on his farm to provide high-energy food for visiting waterfowl. Harris admits that deer and their affinity for corn have presented a challenge to his habitat management practices. For this reason, he plans to grow rice instead. “It’s literally the same kind of high-carbohydrate food that corn is,” Harris said. “The big advantage is that the deer don’t eat rice. In some fields, nearly half of the corn crop gets eaten by the deer.”
Harris has been an avid hunter since he was a young boy; growing up hunting with his grandfather on the bays north of San Francisco cultivated his passion for conserving wildlife habitat. He now owns three farms in Maryland and one in Montana, all under conservation easements through Ducks Unlimited, the largest land conservation owner in the United States, of which he sits on the board.
“The farm is big enough that on a windy day you can be shooting on the farm and the upwind birds will still be there. With the wild ducks, the thing you want to do if you want to keep them is not disturb them too much, otherwise they find another place to go,” Harris said. He has even calculated exactly how many ducks he and his guests can harvest in a year without negatively impacting waterfowl populations, setting the limit at 175 ducks from all four farms.
Harris designates 20 percent of his time to sitting on the board of Ducks Unlimited and of Waterfowl Chesapeake, a Maryland-based non-profit whose mission is to create, restore and conserve waterfowl habitat in the Chesapeake Bay Region. Together they help draw awareness to protecting area wetlands.
Judy Price, the executive director of Waterfowl Chesapeake, has helped the organization raise more than $5 million for habitat restoration and conservation education projects. Waterfowl Chesapeake, the umbrella organization of the annual Waterfowl Festival, held in November in Easton, Maryland, recently created an alliance for waterfowl conservation that consists of a panel of scientific experts that offer advice to current and prospective habitat restoration initiatives. They have also created a restoration project registry, expanding the visibility of high-value projects to the public and potential funders.
When asked why protecting waterfowl habitat is a priority, Price responded, “The annual migration of waterfowl truly enhances our lives throughout the Chesapeake region and, in particular, the Eastern Shore. Not only do we gain ecological benefits, but also significant economic value, from a healthy waterfowl community. By focusing on maintaining strong habitat, hopefully, we can avoid people, years from now, saying, ‘I remember seeing ducks and geese in the skies. Whatever happened to them?’”

Pollution-reducing practices can improve water quality in the Chesapeake Bay and have already improved the health of local rivers and streams, according to new research from the Chesapeake Bay Program partnership.
In a report released today, several case studies from across the watershed show that so-called “best management practices”—including upgrading wastewater treatment technologies, lowering vehicle and power plant emissions, and reducing runoff from farmland—have lowered nutrients and sediment in local waterways. In other words, the environmental practices supported under the Clean Water Act, the Clean Air Act and the Farm Bill are working.
Excess nutrients and sediment have long impaired local water quality: nitrogen and phosphorous can fuel the growth of algae blooms and lead to low-oxygen “dead zones” that suffocate marine life, while sediment can block sunlight from reaching underwater grasses and suffocate shellfish. Best management practices used in backyards, in cities and on farms can lower the flow of these pollutants into waterways.
Data collected and analyzed by the Bay Program, the University of Maryland Center for Environmental Science (UMCES) and the U.S. Geological Survey (USGS) have traced a number of local improvements in air, land and water to best management practices: a drop in power plant emissions across the mid-Atlantic has led to improvements in nine Appalachian watersheds, upgrades to the District of Columbia's Blue Plains Wastewater Treatment Plant have lowered the discharge of nutrients into the Potomac River and planting cover crops on Eastern Shore farms has lowered the amount of nutrients leaching into the earth and reduced nitrate concentrations in groundwater.
“In New Insights, we find the scientific evidence to support what we’ve said before: we are rebuilding nature’s resilience back into the Chesapeake Bay ecosystem, and the watershed can and will recover when our communities support clean local waters,” said Bay Program Director Nick DiPasquale in a media release.
But scientists have also noted that while we have improved water quality, our progress can be overwhelmed by intensified agriculture and unsustainable development, and our patience can be tested by the “lag-times” that delay the full benefits of restoration work.
“This report shows that long-term efforts to reduce pollution are working, but we need to remain patient and diligent in making sure we are putting the right practices in place at the right locations in Chesapeake Bay watershed,” said UMCES President Donald Boesch in a media release. “Science has and will continue to play a critical role informing us about what is working and what still needs to be done.”
UMCES Vice President for Science Applications Bill Dennison echoed Boesch’s support for patience and persistence, but added a third P to the list: perspiration. “We’ve got to do more to maintain the health of this magnificent Chesapeake Bay,” he said.
“We’ve learned that we can fix the Bay,” Dennison continued. “We can see this progress… and it’s not going to be hopeless. In fact, it’s quite hopeful. This report makes a good case for optimism about the Chesapeake Bay.”
Chesapeake Bay Program partners have improved how states track on-farm conservation, helping farmers get credit where it is due and ensuring states know what has been done to meet their pollution reduction goals.
Under the Chesapeake Bay Total Maximum Daily Load (TMDL), or “pollution diet,” each state in the watershed must report their annual progress in promoting agricultural conservation. To streamline this process, the U.S. Geological Survey (USGS) has integrated state and federal data about what conservation practices have been put in place, where. Delaware, Pennsylvania and West Virginia used this new dataset to report their conservation practices in 2012, improving their ability to track their progress toward improving water quality in rivers, streams and the Chesapeake Bay.
While agricultural runoff is one of the watershed’s leading sources of nutrient and sediment pollution, on-farm conservation can lower the amount of nitrogen, phosphorous, sand and silt washing off of farmland. Conservation tillage, cover crops and nutrient management planning can also reduce a farm’s operating costs and improve a farm’s production.

Indeed, a recent U.S. Department of Agriculture (USDA) report on the impact of cropland conservation in the region showed that conservation measures—a number of them put in place voluntarily and made possible through the Farm Bill—have improved and protected water quality and soil health. Published as part of the USDA’s Conservation Effects Assessment Project (CEAP), the report, which uses data collected between 2003 and 2006 and in 2011, showed a five, six and eight percent drop in phosphorous, nitrogen and sediment runoff into the Bay. While Chesapeake Bay Program partners work closely with the USDA, this particular report is not part of the Bay Program's TMDL-related tracking efforts.
“The good work of Chesapeake Bay landowners has generated substantial progress in a short period of time, but more needs to be done,” said Agriculture Secretary Tom Vilsack in a media release. “It is critical that Congress act now to pass a Farm Bill that provides the full array of programs and incentives to build on these efforts.”

Growing scientific evidence shows that pathogens, antimicrobials and hormones are increasingly appearing in livestock and poultry manure across the United States, according to a literature review prepared by the U.S. Environmental Protection Agency (EPA).

These “contaminants of emerging concern”—so named because their risks to human health and the environment may be unknown—could pose threats to plants, animals and people if rain, spills or storage failures push contaminated manure into rivers and streams.
The flow of manure into our waterways has long been linked to nutrient pollution. According to 2010 estimates, manure accounts for 19 percent of the nitrogen and 26 percent of the phosphorous entering the Chesapeake Bay, where it fuels the growth of algae blooms and creates dead zones that suffocate marine life. But research now shows that more of the nation’s manure could contain a new class of pollutants that could have serious implications for water quality.
Manure can contain pathogens, for instance, that could infect humans if allowed to contaminate our drinking water or food crops. It can contain antibiotics and vaccines that could facilitate the development of antimicrobial resistance. And it can contain natural and artificial hormones that, even in low concentrations, could affect the reproductive health and fitness of fish, frogs and other marine life.
Indeed, good manure management has become a key conservation practice in the watershed, where four states—Delaware, Pennsylvania, Maryland and Virginia—rank among the ten highest manure-generating states, according to the U.S. Department of Agriculture (USDA). As livestock and poultry production shift to larger, more concentrated operations, facilities produce more manure than can be used on the surrounding farmland. If this manure is properly applied, stored and transported, it can be kept out of rivers, streams and the Bay.

Streams across the United States are suffering a decline in health, as human development alters stream flow and pushes pollutants into the water.
Between 1993 and 2005, scientists with the U.S. Geological Survey (USGS) sampled the algal, macroinvertebrate and fish communities in thousands of streams across the nation. According to a report released by the USGS National Water-Quality Assessment Program, the health of at least one of these three aquatic communities was altered in 83 percent of the streams assessed.
Healthy streams are critical to our communities. Streams provide drinking water, control floods, support commercial and recreational fisheries, and bring aesthetic value into our lives. But stream flow that is altered by human activities can impact native fish, and excess pollutants can alter plant and animal communities.
According to the USGS, tens of thousands of dams and diversions have contributed to the modification in stream flow of 86 percent of the waters assessed in this study. Excess nutrients have altered algal communities, while excess pesticides have had an adverse affect on macroinvertebrates, many of which can be harmed by the toxins found in insecticides.
But one in five streams in urban and agricultural areas was found to be in good health. This finding suggests that green development, on-farm conservation and other best management practices can help us maintain healthy streams alongside continued development.

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.”

This winter saw an increase in waterfowl along Maryland’s Chesapeake Bay shoreline and Atlantic coast.
While pilots and biologists from the U.S. Fish and Wildlife Service (USFWS) and Maryland Department of Natural Resources (DNR) counted fewer diving and dabbling ducks this winter than they did in the 2012 Midwinter Waterfowl Survey, these same crews counted more geese.
According to a DNR news release, both Canada geese and snow geese were “noticeably more abundant during this year’s survey,” with crews counting 462,000 Canada geese—a three-year high—and 83,300 snow geese—a five-year high. Biologists have attributed the boost in goose numbers to two factors: last spring’s successful nesting season and December snow cover in New York and southern Canada, which encouraged geese to migrate into the Bay region right before the survey was taken.
While more geese could mean more damage to area farms—as the birds forage on green cover crops and grain crops—most farmers “have learned to deal with the problem,” said Larry Hindman, wildlife biologist and Waterfowl Project Leader with DNR. Fluttering plastic flags, bald eagle effigies placed in the middle of fields and the loud bang of a rifle or shotgun have all proven effective at deterring persistent geese, Hindman said, and those farmers who need extra help can find assistance and advice in the U.S. Department of Agriculture’s Wildlife Damage Management program.
Resident Canada geese can pose a problem for rural, suburban and urban residents alike, and are considered overabundant in the region. While the birds do provide hunters with a chance for recreation, resident geese can overgraze wetlands and lawns and leave their droppings to pollute local rivers and streams. While the Midwinter Waterfowl Survey does not make a distinction between resident and migratory geese—as both stocks look the same during an aerial survey—DNR researchers do monitor the resident population using leg bands recovered from hunters.
The Midwinter Waterfowl Survey is used as an index of long-term wintering waterfowl trends. The estimates measure waterfowl populations along the Atlantic Flyway, which is a bird migration route that follows North America’s Atlantic Coast and Appalachian Mountains.
Read the full waterfowl survey results on the DNR website.
Fencing off a stream from livestock, planting trees along a soon-to-be-shaded river or creating marshland to provide habitat to fish, frogs and birds: restoration projects such as these would not be possible without the hundreds of watershed groups working across the Chesapeake Bay region, or the networking needed to connect restoration partners with their peers.
Each year, the National Fish and Wildlife Foundation (NFWF)—which supports Bay restoration with grants offered through the Chesapeake Bay Stewardship Fund—gives restoration partners a break from their intensive on-the-ground work with the Chesapeake Bay Agricultural Networking Forum. Last week, this forum brought more than 100 grantees together in Staunton, Va., to discuss restoration successes, challenges and solutions to common problems, networking with each other and forming invaluable partnerships.
“Our grantees really are the front lines of the Bay restoration effort,” said Amanda Bassow, NFWF Director of Chesapeake Programs. “We need to arm them with all the knowledge, resources and experience we can. These are the people who are accelerating progress, engaging new partners and new landowners, and continually figuring out new ways to get the job done.”
The forum began with a rapid-fire update from grantees working on close to a dozen projects, ranging from forest buffer plantings to the engagement of so-called "absentee landowners”—or those landowners who do not work their own farmland—in conservation. Field trips in and around Staunton gave participants a hands-on look at areas in which progress is underway. On the Merrifield and Ford farms, for instance, located in the Poague Run watershed, landowners have restored stream banks, protected streamside forests and excluded livestock from sensitive waterways.
“Grantees tell me they love the forum because they get re-energized about their work,” Bassow said. “It’s a community of doers, not finger pointers, and when you get them all in a room together, it’s a powerful thing to see.”
Chesapeake Bay Program Director Nick DiPasquale moderated a session at the forum, and found the event to be a meaningful one.
“For farmers and farm service providers, conservation district staff, government officials, funders and non-governmental organizations, this was a great exchange of ideas and approaches on implementing effective and innovative agricultural best management practices,” DiPasquale said. “This forum should help the community save money, clean up local waterways and keep farmers farming while using creative ways to manage nutrients on their land.”

The restoration of forested areas along creeks and streams in the Chesapeake Bay watershed continues to decline.
Called riparian forest buffers, these streamside shrubs and trees are critical to environmental restoration. Forest buffers stabilize shorelines, remove pollutants from contaminated runoff and shade streams for the brook trout and other fish species that thrive in cooler temperatures and the cleanest waters.
While more than 7,000 miles of forest buffers have been planted across the watershed since 1996, this planting rate has experienced a sharp decline. Between 2003 and 2006, Maryland, Virginia and Pennsylvania planted an average of 756 miles of forest buffer each year. But in 2011, the entire watershed planted just 240 miles—less than half its former average.
Farmers and agricultural landowners have been the watershed’s driving force behind forest buffer plantings, using the conservation practice to catch and filter nutrients and sediment washing off their land. But a rise in commodity prices has made it more profitable for some farmers to keep their stream buffers planted not with trees, but with crops. This, combined with an increase in funding available for other conservation practices, has meant fewer forest buffers planted each year.
But financial incentives and farmer outreach can keep agricultural landowners planting.
The Chesapeake Bay Foundation (CBF), for instance, has partnered with the U.S. Department of Agriculture and others to implement conservation practices on Pennsylvania farms. Working to put the state’s Conservation Reserve Enhancement Program (CREP) funds to use, CBF provides farmers across the Commonwealth with technical assistance and financial incentives to plant forest buffers, often on the marginal pastureland that is no longer grazed or the less-than-ideal hayland that is rarely cut for hay.
The CBF Buffer-Bonus Program has encouraged Amish and Mennonite farmers to couple CREP-funded forest buffers with other conservation practices, said Dave Wise, Pennsylvania Watershed Restoration Manager with CBF. The reason, according to Wise? “Financial incentives … make it attractive for farmers to enroll.”

For each acre of forest buffer planted, CBF will provide Buffer-Bonus Program participants with up to $4,000 in the form of a “best management practice voucher” to fund conservation work. This comes in addition to CREP cost-share incentives, which fund forest buffer planting, post-planting care and annual rental fees that run from $40 to $350 per acre.
While Wise has witnessed what he called a “natural decline” in a program that has been available for more than a decade, he believes cost-share incentives can keep planting rates up, acting as “the spoonful of sugar" that encourages farmers to conserve in a state with the highest forest buffer planting rates in the watershed.
“There are few counties [in the Commonwealth] where buffer enrollments continue to be strong, and almost without exception, those are counties that have the Buffer-Bonus Program,” Wise said.
In 2007, the six watershed states committed to restoring forest buffers at a rate of 900 miles per year. This rate was incorporated into the Chesapeake Bay Executive Order, which calls for 14,400 miles of forest buffer to be restored by 2025. The Chesapeake Forest Restoration Strategy, now out in draft form, outlines the importance of forests and forest buffers and the actions needed to restore them.
Farmers in the Chesapeake Bay watershed might soon have an easier time putting pollution credits on the market.
The U.S. Department of Agriculture (USDA) has awarded $2.5 million to five Bay organizations to improve the infrastructure behind water quality trading markets, which allow buyers to purchase "pollution credits" for reductions or cuts in pollution that landowners have made on their properties.
From better determining demand for credit to improving outreach to hundreds of eligible farmers, the planned improvements aim to benefit both the land and those who work it. A farmer who uses conservation practices to reduce his runoff of nutrients or sediment, for instance, can produce on-farm energy savings and water quality credits while improving the environmental health of his land.
Watershed recipients of Conservation Innovation Grants program funding include the Alliance for the Chesapeake Bay, the Chesapeake Bay Foundation, the Maryland Department of Agriculture, the Virginia Department of Conservation and Recreation and the Borough of Chambersburg, Pa.
The Conservation Innovation Grants program is administered by the Natural Resources Conservation Service (NRCS). This year, an additional $23.5 million has been awarded to more than 50 recipients across the nation for innovative and conservation-minded agricultural practices, from improving soil health to increasing on-farm pollinator habitat.
Drivers honk at each other, passing by layers of parking lots and shopping centers; armies of workers wait for a bus; food carts occupy every corner; and pedestrians tow their children through the cement jungle, ignoring crosswalk signals and jumping in front of cars without the slightest bit of fear.
Tucked away in this impervious kingdom called Prince George’s County is a place of natural beauty, where worms dig through compost, chickens play tag and honeybees busily buzz. Here at ECO City Farms, every inch of ground is precious; a blanket of veggies and fruits is shadowed by rows of hanging pots. The completely solar and geo-thermal powered farm located in Edmonston, Md., raises chickens and ducks, keeps bees and grows enough crops for a CSA (Community Supported Agriculture) operation--all on one acre of land.

Also known as Engaged Community Offshoots, ECO City Farms manages land and grows food in ways that benefit the Chesapeake Bay watershed: with no chemical fertilizers, and no petro-based or non-organic treatments, pesticides, herbicides or fungicides.
Impressive, but perhaps impossible? ECO City relies on natural processes to deter insects. Did you know planting marigolds next to your tomato plants will keep insects away? These simple but natural technologies define ECO City’s farming methods and ensure that the chemicals typically used in gardening operations do not end up in our food or the nearby Anacostia River and Chesapeake Bay.
ECO City implements farming methods that are healthy for the Bay watershed and its residents, but it also understands the importance of educating and engaging the local community.
The organization's tagline is "creating a just and sustainable world," a mission statement that trumps the money-making agendas of any commercial big-box farm. ECO City understands its role to exceed the agricultural industry and remains committed to connecting community members to their food.
ECO City educates and empowers local residents, giving them the tools and knowledge they need to kickstart their own urban agriculture operation. Dedicated to keeping food in the hands of the people, ECO City is not your average farm.

What's new at ECO City:
Located in the residential neighborhood of Edmonston, Md., a Washington, D.C., suburb, the farm hosts volunteer Saturday work days and tours of the farm.
The New Urban/Immigrant Farmer Training program teaches interested adults the tenants of urban farming over the course of a year, and a new DIY (Do It Yourself) Green Building Series covers how to capture and reuse rain water, how to build a hoop house, how to create a green roof and more!
A new commercial kitchen will allow the farm to offer educational cooking courses and to turn produce into products (basil becomes pesto sauce, tomatoes and peppers become salsa!)

Luke Brubaker lives in the house his father bought in 1929. His grandchildren play in the same creeks he played in as a child, and he farms the same land that his father farmed. But Luke's land in Lancaster County, Pennsylvania, has changed drastically since the days of his father; it is under pressure from higher rates of development (the large housing development at the edge of his property is one example); there is an increased use of pesticides, auto exhaust, and other chemicals that can leak into his groundwater; and a decrease in the amount of forested land allows nutrients from soil and bacteria from animal manure to easily run off into waterways instead of being absorbed by trees.
As Brubaker's land has changed, so has the agriculture industry; soaring energy and production costs and a plethora of environmental regulations mean that selling a gallon of milk isn't as easy as it used to be.
Nevertheless, Luke treats his land in a way that recognizes its vulnerability, farming it in a way that ensures it will be fertile in the future. His mindful practices have awarded him with productive land and healthy cattle, as well as a U.S. Dairy Sustainability Award, a Center for Advanced Energy Studies/Idaho National Laboratory Award for “Outstanding Achievement in Energy," and recognition as 2011 Innovative Dairy Farmer of the Year.
"I hope that this land will not only be preserved for farming," explains Luke, "but that the soils will be preserved on the land so that my grandkids can farm this, so that this can be food for the future."
Luke has grown his father's 18-cow dairy farm to a 900-cow operation, and hopes to keep the business in the family. Because he cares about the longevity of his land, he is concerned less with the quantity of milk he produces, and is instead concentrated on the reuse of energy and the quality of his products.
And while many farmers say that new regulations threaten their financial stability, Luke insists that following and exceeding these guidelines have helped him save money and keep his land in good health for future generations.
"It's an economic value to keep the water on the field, and keep the nutrients on the field, so it only makes sense to do good conservation practices," explains Luke. "This is what’s so important: that farmers realize the economic value of conservation practices, rather than doing it because they have to do it. And sometimes over the years, it has taken me time to realize that some of the old ways that we used to have aren’t the best ways."
On my tour of Brubaker Farm, the relationship between Luke's conservation ethic and economic good sense becomes obvious; the farm reuses everything and anything possible, especially cow manure!
"The more land that we can preserve and farm properly, the more soil we're going to have; we're going to be able to grow the food of our nation. That's very important to me," says Luke. "There's a great livelihood that can be achieved from good agricultural practices."
But what are "good" agricultural practices? Here are a few that are being implemented on Brubaker Farm:
Power in poop
At Brubaker Farm, the cows are kept in an open-air, temperature-controlled, shelter where they are able to roam from building to building. Their bedding is replaced regularly to keep them comfortable, and their feed, most of which is grown on the farm, is calculated to the tee.
"Our cows are fed probably better than some of our families are fed because we measure and weigh every bit of feed so they get the right nutrition," says Luke.
The cow's manure is swept away from the shelter every few hours. This differs from "free range" farms, where cattle are permitted to roam (and even sometimes, poop) where they please. The advantage of keeping the cattle in a controlled environment is that cows can remain cool in the summertime (they prefer cooler temperatures), and their manure is not laying around somewhere in the grass, or even worse, in a stream.
In fact, Brubaker understands his cow's manure to be just as valuable as the milk they produce. After an automatic cleaner collects manure from the cattle shelters, the manure goes into a machine called a "digester," which converts manure into methane gas that can be used (and sold) as an energy source.
On the Brubaker Farm, the solid manure wastes are converted into bedding for the cows. After it goes through the digester, it is pathogen free, making it the perfect, safe option for keeping cows comfortable.
The liquid manure is converted into electricity. Luke sells enough electricity to power 200 homes. The rest he reclaims as energy to fuel his farm's operations; the electricity is used to heat and pasteurize the milk before it is taken off the property, and to clean the cows’ towels (each cow gets his or her own cleaning towel!)
Luke is in the process is making a solar hot water system so he can make his own hot water from the farm's solar panels, which now provide electricity to 100 homes at peak sun.
The Brubaker's creative use of excess poop/energy has opened a whole new market to the family; in a recent year, they generated more profit from selling electricity than from selling milk!
No till farming
In his 1943 book, Plowman's Folly, Edward H. Faulkner said, "the truth is that no one has ever advanced a scientific reasoning for plowing." Yet, tilling soil is still protocol for many farms.
Traditionally, soil is loosened by a plow, or tilled, so that oxygen, water, and nutrients can reach the area where a crop's roots grow. Today, tilling requires the use of heavy machinery, which requires both fuel and labor to operate.
When the soil is left in place, it is able to maintain its structure and better hold water. Not tilling the soil cuts back on fuel and labor costs. It also means that the soil is not loosened, and is therefore not as prone to erosion.
"After you no till for a couple of years, your soil gets roots," explains Luke. "It’s kind of like a sponge, and it allows the water to permeate into that sponge and holds it there. If you have a dry year, you’re going to have a better crop, because it holds that moisture there just like a sponge."
"Cover crops" are vegetation that holds the soil in place with its roots, preventing erosion even when a commercial crop is not being grown.
Cover crops shade the soil, preventing sunlight from fueling fast-growing weeds, and keeping the soil cool. Cover crops also discharge excess organic materials into the soil through their roots. These materials provide food for soil microbes and replenish nutrients that a future commercial crop, will benefit from.
If a field is fertilized heavily, cover crops can take up any excess fertilizer that was not used by a commercial crop; this will decrease the amount of nutrient pollution leaching into the groundwater and nearby streams.
A stream on Brubaker's property is a favorite swimming hole for his grandchildren, and a favorite habitat for brook trout. Luke usually keeps his cattle in a controlled environment because keeping cattle away from this stream minimizes the sediment and bacteria pollution going into the waterway.
"One of the best things that small farms can do is to keep their cattle out of the streams," says Luke. "If the cattle have access to the whole stream and banks, they have a tendency to break the shores down, and that’s what causes sediment (pollution). We have fences to keep the cattle out so they aren’t breaking the banks of the stream."
Stream bank fencing also prevents rainwater, and the nutrients it carries, from ending up in waterways. Keeping these products on the field, instead of in the waterways, is not only beneficial to wildlife and plants, but to the farmer himself- it means more nutrients and water stay in place to fuel crop growth!
On Brubaker's farms, streamside trees (known as forest buffers) shade the stream, keeping it cool enough for trout. The tree's roots that stabilize stream banks and absorb any nutrients before they end up in the stream.
"It’s important for somebody else that the streams are clean, but it’s important for us (farmers) that our nutrients and water are on our fields," says Luke. "We know that when we have a clean stream, we know that our nutrients and our water are staying on our fields like they’re supposed to.

Maryland farmers planted nearly 430,000 acres of cover crops in fall 2011 through the state’s Cover Crop Program, the largest planting in Maryland history, according to the Maryland Department of Agriculture (MDA). The 2011 figure exceeds Maryland’s 2013 Chesapeake Bay pollution reduction milestone for cover crop plantings by 21 percent.
Cover crops are widely considered one of the most cost-effective and environmentally sustainable ways to control soil erosion and reduce nutrient pollution to the Bay and its rivers in winter. Collectively, the 429,818 acres of cover crops planted in 2011 will prevent an estimated 2.58 million pounds of nitrogen (60 percent of Maryland’s total pollution reduction milestone goal) and 86,000 pounds of phosphorus from entering the state’s waterways.
Farmers plant cover crops such as rye, wheat and barley in the fall after summer crops are harvested. As they grow, cover crops recycle unused plant nutrients remaining in the soil, protect fields against wind and water erosion, and help improve the soil for next year’s crop.

As the sun rises, bald eagles swoop from tree to ground; Canada geese honk happily in a nearby field; and a crew of scientists, boaters and trappers begin a day’s work at Blackwater National Wildlife Refuge in Cambridge, Maryland. The mission? To keep the marshes that fringe the shoreline along this part of the Chesapeake Bay from disappearing.
Although wetland degradation can be attributed to a variety of factors, the field crew at Blackwater is focusing their efforts on one cause they believe can be easily controlled: an invasive rodent called nutria. Native to South America, nutria were introduced to the United States in the early 20th century for their fur, which was thought to be valuable at the time. These 20-pound animals with the build of a beaver and the tail of muskrat may seem harmless, but their effect on marshes across the United States has been devastating.
An overindulgent diet of wetland plants, a lack of natural predators and ridiculously high reproduction rates are characteristics that have led nutria to be labeled as an “invasive species.” Simply put, this means they aren’t originally from here, and they harm the Chesapeake Bay ecosystem.
Nutria eat 25 percent of their body weight in marsh plants per day. Let’s put that into perspective: if you’re a 120-pound woman, you’d have to eat 30 pounds of plants each day to eat like a nutria. And since marsh plants don’t weigh all that much, you’d find yourself eating a lot of vegetation.
To make matters worse, nutria tear up the roots of marsh plants when they eat, making it impossible for new plants to grow. As a result, large areas of marshland erode away to open water.
“One property owner on Island Pond had a 300-acre marsh property. Now there’s about 30 acres left,” describes Stephen Kendrot, who works on the Nutria Eradication Project for the U.S. Department of Agriculture’s Animal and Plant Health Inspection Services (APHIS).
Aerial photographs of Blackwater depict a similar scenario. The refuge has lost 50 percent of its wetlands since nutria were introduced in the 1940s. The photos below depict Blackwater in 1939 (left) and 1989 (right.)
Certainly, this loss is a tragedy for Eastern Shore landowners. And while residents may be disappointed that they can’t look out at a beautiful marsh view or help their children find frogs in their backyard wetland, loss of marshland also results in irreversible ecological consequences.
Marsh plants are incredibly beneficial to the environment because they:
In the early 1990s, U.S. Fish and Wildlife staff fenced off random quarter-acre plots in Blackwater’s marsh, excluding nutria but allowing other animals to enter. After several growing seasons, the marsh plants inside the enclosure began to grow, while the vegetation outside the fencing declined. This finding proved that nutria was the direct cause of marsh loss.
Like most rodents, nutria are prolific breeders. This means that those areas with just one or two nutria won’t stay that way for long. Female nutria are fertile as young as six months old, and they can become pregnant again just 24 hours after giving birth. (Essentially, a lifetime of being pregnant.)
“Sometimes we miss a couple animals and they might find each other and start a new population,” explains Kendrot.
As the nutria problem grew serious, federal and state agencies, universities and private organizations partnered to form the Nutria Eradication Project. The project team is made up of academically trained biologists and Eastern Shore natives who have been trapping nutria since they were kids.
Although nutria have been eradicated from Blackwater since the project took off in 2002, there are still substantial populations in other, less densely populated areas. These are the spots the Nutria Eradication Project is now targeting.
Today, Kendrot and I tag along with the field team to survey for nutria on the Wicomico River, an area where residents have reported nutria.
Mario Eusi, who has been trapping nutria for years, drives our boat down the Wicomico River and turns into a narrow inlet. This area is privately owned, but the landowners have granted the team permission to access their property. This type of support is critical to the project’s success.
“About half the nutria we find are on private property,” Kendrot explains. “And almost all the property on the Wicomico is privately owned.”
Consequently, the team dedicates lots of time to public outreach. Kendrot and other team members make phone calls and sit down at kitchen tables across Wicomico and Dorchester counties to explain the harmful effects of nutria. The team must assure landowners that if they grant access to their land, they are preventing their property from disappearing. From this perspective, the federally funded Nutria Eradication Project is actually a public service to waterfront landowners – the team does their best to prevent residents’ marshland from sinking into the Chesapeake Bay.
Today we are tracking nutria, which means looking for signs such as scat, paw prints, chewed plants, flattened grass beds – anything to prove “a nutria was here.” A good tracker must have both a keen knowledge of what nutria signs look like and the sharp senses to catch them, regardless of weather conditions or the speed of the boat cruising down the river. The team also tracks nutria through other methods, including dogs, radio collars and hidden video cameras.
Finding the “nute” is the bigger half of the battle. “Trapping is the easy part,” the field team assures me. Team members must first find signs of nutria before they can decide where to set traps in the spring. I admit: I’m relieved I won’t have to see any nutria in traps today.
The tide is rising, so we have to be quick; soon, the water will wash away paw prints and make it difficult to identify nesting areas. Eusi points out the difference between nutria and muskrat scat. His eye for detail and ingrained awareness of the great outdoors makes him an excellent tracker.
Suddenly, we find a nesting site: an area of flattened grasses that looks like someone has been sitting in the marsh. The signs multiply, and soon the team is out of the boat, bushwhacking through twelve-foot high cattails. I try to catch up, but my foot gets stuck in the mud, and soon I am up to my hips in wetland!
As we continue through the marsh, we find one of the most conclusive signs of an active nutria population: a 10-foot-wide “eat-out,” or an open area where nutria have eaten all of the grasses and their roots. These bare, muddy areas, stripped of all vegetation, eventually erode away into open water.
When we spot a larger “eat-out” not a few steps away, it occurs to me that the two areas will likely merge into one giant mud flat. The cattails I just bushwhacked and the mud I sank into will soon disappear forever into the Wicomico River.
Since we have successfully tracked nutria on the Wicomico today, the team can now think about how to trap the animals.
When a nutria is trapped, it drowns quickly. Team members record the age and sex of each nutria to determine if it is newly born or if it was missed during the previous round of trapping. One way to estimate a nutria’s age is to weigh its eyeballs, because the lenses grow at a fixed rate throughout its life.
Dead nutria have another benefit: carcasses left in the wild provide food for bald eagles, turtles and other wildlife.
While the term “eradication” may conjure up images of ruthless killers, the field team does not seek to conquer these rodents. Rather, the goal is to preserve the wetlands that support the Chesapeake Bay ecosystem and define the culture and economy of Maryland’s Eastern Shore.
The team’s work also benefits the region’s economy as a whole. It’s estimated that nutria cost Maryland $4 million in lost revenue in 2004 alone. The Bay’s crab and oyster fisheries are just two of countless industries that depend on coastal wetlands. The natural filtering capabilities of marsh plants cost millions of dollars to imitate with wastewater treatment plants. Nutria eradication doesn’t just save our wetlands; it also saves our money.
Nutria are often confused with beavers and muskrats, two native and ecologically important mammals. The Fish and Wildlife Service offers a nutria identification page on its website to help you distinguish the difference between these three similar-looking species.
If you think you may have nutria on your property, you should contact the Nutria Eradication Team.
In Louisiana, the nutria infestation problem is even worse. The current generation is carrying on the traditions of fur-bearing trappers thanks to the state’s Nutria Control Program, which pays trappers per nutria they collect. The state even promotes nutria trapping by providing recipes for dishes such as smoked nutria and nutria chili!
Real fur may no longer be a faux pas for the environmentally conscious fashionista. Coats and hats made from nutria fur are considered by many to be “green and guilt-free.” George Costanza thought so, anyway: in an episode of Seinfeld, he replaces Elaine’s lost sable hat with another made from the fur of this invasive rodent.
When most people talk about forests, they mention hunting, or the timber market, or environmental conservation. But when Susan Benedict discusses her forest – a 200,000 acre property in Centre County, Pennsylvania – she talks about family.
“We all work together. This is a family operation,” she says as we drive to her property along a Pennsylvania State Game Lands road that winds through the Allegany Mountains from Black Moshannon to Pennsylvania-504.

A desire to keep the mountaintop property in the hands of her children and grandchildren motivated Benedict to implement sustainable forestry practices, participate in Pennsylvania’s Forest Stewardship Program and certify the property under the American Tree Farm System. By managing her forest in an environmentally conscious way, Benedict ensures that stands of ash, red oak and beech will be around in a hundred years for her great-grandchildren to enjoy.
But Benedict’s involvement in forest conservation doesn’t mean that she’s rejecting the land’s economic and recreation potential. The property’s plethora of hardwoods allows the family to participate in the timber market. As a large and secluded mountaintop property, it has attracted wind farms seeking to turn wind into energy. Its location along the Marcellus Shale makes it a desirable location for natural gas developers. This multitude of interested parties, each with its own vision, can be overwhelming for any property owner.
Since different stakeholders preach different benefits and drawbacks of extracting these natural resources, Benedict took charge and carefully investigated the issues herself, knowing her family’s land was at stake. Her decisions balance the property’s economic potential with her desire to keep her family forest as pristine as it was when she explored it as a child.
We talk so much about the environmental benefits of trees that it’s easy to forget that they’re also a business.

“My forester assures me that your woods are like your stock portfolio,” Benedict explains. “You don’t want to cut out more annual growth than what you’re generating, and in fact, you want to shoot for (cutting) less than what you’re generating. Right now, we are good; what we are taking out, we are generating.”
Before any logging is done, a county forester walks the property and designates which trees can be removed. Then it’s time to cut. Benedict has one logger, an ex-Vietnam veteran whose wife occasionally accompanies him. “He cuts whatever the mills are wanting,” says Benedict.
The challenge occurs when mills want something that shouldn’t be cut. “It’s a little more problematic because we have to market what we want to get rid of, instead of the lumber mills telling us what they want,” Benedict explains.
But Benedict won’t let natural resource markets sway her forest management decisions. She’s taking charge by telling lumber mills that she’ll give them what she wants to give them – no more, no less. Of course, the economic incentives of sustainable forest management make saying “no” easier.
One of these economic rewards is the Department of Agriculture’s Environmental Quality Incentives Program (EQUIP), which provides financial and technical assistance to landowners seeking to “promote agricultural production and environmental quality as compatible national goals.”
Benedict’s EQUIP project will enhance growth on mass-producing trees such as hickory, oak, cherry, hazelnut, beech nut and others that produce animal feed. “Basically, we want to get the trees to grow quicker, and re-generate better.”
Family health problems put Bendict's EQUIP project on hold. Since it needed to be completed by the end of summer, Benedict’s brothers and her three sons (age 15, 24 and 27) held mandatory family work days each weekend from the Fourth of July to the end of September.
“It’s a 200,000-acre property, which translates to a lot of work. But I think that’s good,” Benedict assures me, even though she also sweat through the word during the height of summer’s humidity. “When you have concentrated time like that, you actually talk to each other. If you meet for an hour meeting, no one ever gets around to saying what they want. You get down to what’s real.”
Using the forest as a mechanism to unite her family has been Benedict’s goal since she and her brothers inherited the property after her father’s death.
Benedict tells me that her three boys “have to help out, whether they want to or not.” Their involvement – even if it is forced sometimes – allows the family to connect to the property. Benedict hopes the hard work will inspire them to adopt sustainable forestry management practices when they inherit the land.
We’ve all experienced times when nature takes over and there’s nothing we can do about it – whether we’re a farmer that’s experienced a devastating drought or a commuter who’s had to pull over in a heavy rainstorm because we couldn’t see the road in front of us.
This happened to Benedict and her team six years ago, when a three-year gypsy moth infestation destroyed 80 percent of a red oak stand. The damage cost her more than one million dollars in timber profits on a 2,000-acre lot.
“Al (Benedict's logger) had worked so hard on the stand. And it’s not a fun place to work – rocky and snake-infested. We were all so proud of how it came out. And then three years worth of caterpillars, and it was destroyed.”
Biological sprays of fungi can sometimes prevent gypsy moth infestations. The caterpillars die after ingesting the fungi for a few days.
Benedict could have sprayed the fungi, but it may not have worked. It’s a big risk to take when you’re paying $25 per acre (that’s $50,000 in total). Not only do you need the money, but you must have three consecutive rain-free days in May, the only time of year you can spray.
So when the emerald ash borer – the invasive green insect that has destroyed between 50 and 100 million ash trees in the United States – made its first appearance in Pennsylvania, Benedict began cutting down her ash trees. “We got them to market before they got killed.”
By paying attention to both environmental and market pressures, Benedict’s forest is both sustainable and profitable.
Benedict’s property is isolated. For wind-power developers, that means fewer people will complain about the loud noise and shadows that make living near wind turbines burdensome. The land is also atop a mountain, which, of course, means it experiences high winds.
“It’s very hard to decide to have that much development on your property, but honestly, it will provide a nice retirement for my brothers and me,” Benedict says. “Everyone I talk to assures me that once the construction phase is over, it doesn’t hurt the trees, it doesn’t hurt the wildlife. The wildlife could care less, which has been my observation on most things that we do. After it gets back to normal, they don’t care and they adjust.”
Environmental surveys, which are required by law before construction, affirm Benedict’s insights. A group hired to do a migratory bird study constructed a high tower atop the mountain. “They stayed up there every evening and morning in March,” Benedict says with a shiver.
Another contractor is delineating wetlands on the property: identifying and marking wetland habitat and making sure construction does not affect these areas.
Benedict and her family even had the opportunity to learn what kinds of endangered and threatened animals live on their property. “They found seven timber rattlesnake dens, and had to relocate one of the turbines because it was too close to the den,” Benedict explains. The teams also surveyed Allegany wood rats and northern bulrushes, a critical upland wetland plant.
“I decided to [lease property to the wind farm] because the only way we are ever going to know if wind is a viable technology is if we get some turbines up, see what works, see what doesn’t work, and allow that process of invention to move. And we have to have someone to host it.”
And according to the surveys, Benedict’s property is the perfect host.
As Benedict drives her pickup around the property, she points out the site of her father's former saw mill, where she once worked, and shows me to the cabin that the family built after her grandfather died in 1976. Nearby, there's a section of forest that the family is converting to grouse habitat, which will support her brother's love of grouse hunting.

The uses of the property fluctuate as family members' interests change. Benedict affirms that managing the property sustainably will give her grandchildren the freedom to pursue their interests in the years to come.
"A lot of people go the route of having a conservation easement, but who knows what the best use of that property is going to be in 100 years. If my dad did that, we would have very little use of the property now, and certainly very little flexibility with these things, especially the wind and natural gas."
Benedict is a member of the Centre County Natural Gas Task Force. "You hear all sorts of things about natural gas development and water resources, and in order to make sure it wasn’t going to be horrible, I joined the task force," she explains.
Benedict also allows 15 or so individuals to hunt and fish on her property for a small annual fee. Control of the deer population in particular is essential for her timber operations.
But no matter what happens, Benedict insists, the forest will stay in the family.
"We made a pact that everyone will have to sell all of their belongings before we sold this," she says. "There's some things, you know, you got to make work out."
Benedict’s forest management practices and involvement in the sustainable forestry community has earned her recognition as a 2011 Forest Steward Champion by the Alliance for the Chesapeake Bay.
The Maryland Department of Agriculture has received $650,760 from the USDA Natural Resources Conservation Service to implement progressive management practices for drainage systems on the Eastern Shore.
The funding, awarded through a Conservation Innovation Grant, will help the state meet its Watershed Implementation Plan (WIP) goals. The state will use the funding to use the most advanced technology available to protect the Bay and help reduce pollution while meeting modern drainage needs.
“There are 820 miles of public ditches on the Eastern Shore that were originally designed to manage agricultural drainage,” said Agriculture Secretary Buddy Hance. “Today, those ditches also support storm water drainage from urban town centers, state highways, and commercial and residential development. As a result, many of these ditches are very seriously stressed.”
Most of the Eastern Shore’s ditches were constructed in the 1960s and 1970s in Caroline, Worcester, Wicomico and Somerset counties. Collectively, they drain 220,000 acres of land.
Over the past ten years, MDA has worked with the University of Maryland to develop technologies and management recommendations that reduce pollution and improve drainage ditch function. Using the NRCS grant, Maryland will identify and target the most stressed ditch systems. It will them implement management practices to reduce runoff and improve water quality, including water control structures, phosphorous absorbing materials, weed wiper technology, and algal turf scrubber technology.

The National Fish and Wildlife Foundation will receive nearly $850,000 through a grant from the USDA Natural Resources Conservation Service (NRCS) to help Chesapeake Bay watershed farmers convert manure to energy.
The grant will be used to help farmers in Delaware, Maryland, Pennsylvania, Virginia and West Virginia convert excess manure to energy to generate income. The project will also improve the Bay’s health by reducing land application of manure. Efforts will be concentrated in four of the region’s “phosphorus hot spots” – areas with high concentrations of phosphorus in the soil.
The funding was provided through the 2011 Conservation Innovation Grants, a program that invests millions in innovative conservation technologies that address natural resources issues.
"The grants will help to spur creativity and problem solving to benefit conservation-minded farmers and ranchers," said U.S. Agriculture Secretary Tom Vilsack.

More than 1,700 Maryland farmers will plant a record 550,000 acres of winter grains this fall through the state’s Cover Crop Program.
This acreage represents 155 percent of Maryland’s cover crop goal in its Phase 1 Watershed Implementation Plan, which spells out how the state will meet federal pollution reduction requirements. Cover crops are considered one of the most cost-effective ways to reduce pollution and help restore the Bay.
Maryland’s Cover Crop Program provides farmers with grants to plant cover crops on their fields immediately following the summer crop harvest.
Cover crops are grains such as wheat, rye and barley that are planted in the fall. Once established, cover crops recycle unused nutrients, helping to improve the soil for next year’s crop. Cover crops also control soil erosion and reduce the amount of nutrients that run off the land into nearby waterways.
Visit Maryland Gov. Martin O’Malley’s website to learn more about the cover crop enrollment figures.
Eleven federal agencies, including the Environmental Protection Agency, the Department of the Interior and the Department of Agriculture, have joined together in a new initiative to revitalize the Anacostia and Patapsco rivers.
The Urban Waters Federal Partnership will focus on the two Chesapeake Bay region rivers, as well as five other waterways throughout the United States, as pilot locations for the new initiative. The partnership’s goal is to help underserved communities access and benefit from their local waterways.
Urban waterways like the Anacostia and Patapsco rivers provide local residents with drinking water and opportunities for fishing, boating and swimming. Cleaning up and restoring these rivers is essential to protecting human health, improving quality of life, and connecting people to their local natural areas.

What do farms, manure, and a developing technology for creating fertilizer have to do with the Chesapeake Bay? Well, almost one-quarter of the Chesapeake Bay’s 64,000 square mile watershed is agricultural land. Runoff from farmland inevitably drains into the local streams, creeks and rivers that flow to the Chesapeake Bay.
When best management practices are not implemented on agricultural lands, runoff can carry animal waste and excess fertilizer into these waterways, overloading them with nutrients, bacteria and pathogens.
A developing technology called anaerobic digestion has been proposed to reduce phosphorus runoff from many farms. Pilot studies have been conducted in several locations around the world, including at least three Chesapeake Bay watershed states.
Anaerobic digesters, or biodigesters, have become an increasingly popular tool for managing manure on farms. Biodigesters are thought to have several benefits, including reducing farm animal waste runoff, producing nitrogen-rich liquid that can be used as fertilizer, and producing phosphorus-rich solids that can be processed into mulch and other products that would reduce runoff.
Biodigesters are increasing in popularity for use with dairy farms and manure handled as a liquid, slurry or semisolid. However, a Bay Program website visitor wanted to know about the effectiveness of using biodigesters on poultry farms with litter feedstock to improve water quality in the Bay and its tributaries.
One study conducted in the Bay watershed for the Propane Education Research Council tried to determine if this method could decrease the phosphorus in the liquid effluent from the digester exit point. Unfortunately, the study concluded that this was not the case. Phosphorus was only decreased by approximately 5 percent – the same rate of reduction without the anaerobic digestion process. The council concluded that significant phosphorus reduction could be possible if a separate post-digester step was added.
According to that study, the use of biodigesters would not be an effective way for farmers to help improve water quality.
John Ignosh is a scientist with the Virginia Cooperative Extension at Virginia Tech, working on agricultural byproduct utilization. “As far as digesters [used for] litter,” he said, “there have been a few pilot projects looking at this. The main challenge is that digestion is better suited for slurry type feedstocks.”
Most discussion of anaerobic digesters is in reference to digesters using a slurry type feedstock, but Ignosh said there have been pilot projects with litter feed conducted in Maryland, Virginia and West Virginia, among other locations.
An important note is that regardless of the type of feedstock used for the biodigesters, there is not a significant reduction in nutrients from the waste. Nitrogen enters the digester as ammonium and organic nitrogen, and the ammonium is not destroyed in the digester. Instead, the organic nitrogen is converted to ammonium. So the nitrogen in the effluent from the digester typically ends up being higher than when it went in. Similarly, the microorganisms used in the digester do not consume phosphorus. Although some of the phosphorus can be converted to a soluble form, the total mass of phosphorus remains constant.
Therefore, while anaerobic digesters may be useful for producing biogas to create energy and manage waste, they do not reduce the amount of nutrients in the fertilizer or other products it might result in. So fertilizer that is made from a biodigester and is used on farmland would not decrease the amount of nitrogen and phosphorus that would run off the land. These devices also tend to be prohibitively expensive for many farms and do not provide the best benefit for the investment.

The USDA Natural Resources Conservation Service has released a study showing that effective use of conservation practices on farmland throughout the Chesapeake Bay watershed is reducing nutrient and sediment pollution to the Bay and its rivers.
The study, “Assessment of Conservation Practices on Cultivated Cropland in the Chesapeake Bay Region,” quantifies the environmental gains of using conservation practices and identifies opportunities for farmers to reduce even more pollution.
Agricultural conservation practices such as cover crops, conservation tillage and forest buffers help reduce and absorb excess nutrients and sediment before they can run off farmland or soak into groundwater.
According to the study, agricultural conservation practices have reduced edge-of-field sediment losses by 55 percent, surface nitrogen runoff by 42 percent, nitrogen in sub-surface flow by 31 percent and phosphorus by 40 percent.
“This study confirms that farmers are reducing sediment and nutrient losses from their fields,” said Dave White, chief of the USDA Natural Resources Conservation Service. “Our voluntary, incentives-based conservation approach is delivering significant and proven results.”
The study shows that using additional conservation practices on farmland prone to runoff and leaching could reduce even more nutrient and sediment pollution. Targeting conservation practices in these high-need areas can reduce per-acre nutrient and sediment losses by more than twice that of treating acres with low or moderate conservation needs.
Scientists and officials will use the study results to better focus on priority conservation needs and achieve greater pollution reduction results throughout the Bay watershed.

The USDA Natural Resources Conservation Service (NRCS) in Maryland and Bay Bank, the Chesapeake Bay’s conservation marketplace, are working together to help agricultural operators and forest landowners implement conservation practices that will make them eligible to receive private funding to protect and enhance important habitats, forestland and clean water.
The partnership provides financial assistance for conservation practices that improve habitat conditions for critical species such as brook trout, bog turtles, Delmarva fox squirrels and Atlantic white cedar. Practices that benefit other habitats and water quality, including wetlands and forest buffers, are also eligible.
Bay Bank is a collaborative effort to increase the pace and scope of conservation across the Chesapeake region. Bay Bank integrates existing programs and policies and uses innovative, market-based solutions to support “ecosystem services” that people depend on. As participants implement their conservation practices, groups such as wastewater treatment plants and private foundations may purchase credits from their practices to meet their permits or organizational goals.
NRCS will provide assistance through its Environmental Quality Incentives Program (EQIP). Bay Bank will provide program participants with tools and support to help them engage in ecosystem markets.
To learn more about the program, contact NRCS at your local USDA service center or your local soil conservation district. Additional information can be found online at thebaybank.org. Applications are due May 1.
Maryland farmers planted a record 398,679 acres of cover crops on their farms last fall, exceeding the state’s cover crop goal by 20 percent, according to the Maryland Department of Agriculture.
Cover crops are considered one of the best and most cost-effective agricultural conservation practices, also known as best management practices (BMPs). Cover crops help protect the Chesapeake Bay and local waterways by controlling soil erosion and reducing nutrient pollution runoff.
Collectively, the 398,679 acres of cover crops will prevent an estimated 2.4 million pounds of nitrogen and 80,000 pounds of phosphorus from potentially polluting the Bay and its rivers.
“Maryland is committed to achieving our Bay restoration goals by 2020, five years ahead of any other state in the watershed,” said Maryland Gov. Martin O’Malley. “The fact that farmers exceeded their goal and helped us get 60 percent of the way toward our overall two-year goal across all sectors shows that we can reach our early target.”
Farmers plant cover crops in the fall after harvesting their summer crops. Rye, wheat, barley and other cereal grains are planted as cover crops because they grow in cool weather.
Visit the Maryland Department of Agriculture’s website to learn more about cover crops.
A record 1,668 Maryland farmers will plant more than 500,000 acres of winter grains on their fields this year through the state’s cover crop program, according to the Maryland Department of Natural Resources. This is 155 percent of Maryland’s two-year milestone for cover crops.
Cover crops are a key component of restoring the health of the Chesapeake Bay by reducing polluted runoff from farm fields. Farmers can plant grains such as wheat, rye and barley in the fall to absorb unused nutrients and control soil erosion.
“Maryland’s cover crop program has the potential to do more for the Bay than ever before,” said Maryland Agriculture Secretary Buddy Hance. “Maryland farmers are on track to exceed the two-year milestone for cover crops with record number of approved acres.”
In addition, the Maryland Department of Agriculture (MDA) has received a $600,000 grant to implement a cover crop management tool, which will provide data for the Chesapeake Bay model. The tool will use remote sensing to see how efficiently fields planted with cover crops are absorbing nutrients. Farmers will receive reports about their fields from this tool so they can better manage cover crops in the future.
MDA has also launched a pilot program called Conservation Tracker, which will provide accurate accounting of best management practices (BMPs) on Maryland farms. Conservation Tracker will geo-reference farms that use BMPs and calculate their nutrient reduction credits.
The program, now being piloted in Talbot County, will ultimately help MDA target resources to areas that will achieve the greatest benefits to local waterways and the Bay, as well as help the state track and report on progress toward its pollution-reduction milestones through BayStat.
The U.S. Department of Agriculture (USDA) will expand outreach and innovative conservation practices on farmland in three small watersheds in Maryland, Pennsylvania and Virginia to show how focusing funding, sound science and strong partnerships in small geographic areas can help improve the health of local waterways and ultimately the Chesapeake Bay.
The three small watersheds, called “showcase watersheds,” are:
USDA’s goal is to reach out to all of the farmers in each watershed to learn about the types of voluntary conservation practices they are currently using and to let them know about opportunities for financial and technical assistance.
Each watershed has its own restoration goals and will receive additional funding and staff to help increase the use of agricultural conservation practices on local farms. The U.S. Environmental Protection Agency is also contributing funding, and the U.S. Geological Survey will conduct local water monitoring. Local watershed groups and nonprofits are also involved in the efforts.
The showcase watersheds concept is part of the USDA’s plan to implement new conservation practices on four million acres of farmland in the Bay watershed by 2025, a commitment included in the federal government’s recently released Strategy for Restoration and Protection of the Chesapeake Bay Watershed.
“The showcase watersheds strengthen USDA’s commitment to funding priority conservation practices in places that will do the most good for water quality in the Bay and its tributaries,” said USDA Deputy Secretary Kathleen Merrigan at an event to announce the showcase watersheds.
The USDA’s Bay watershed work is funded in large part by the Chesapeake Bay Watershed Initiative, which was established in the 2008 Farm Bill and provides $188 million from 2009-2012.
Visit the USDA’s website for more information about the showcase watersheds and other Chesapeake Bay activities.
The U.S. Department of Agriculture (USDA) has released $23 million for the Chesapeake Bay Watershed Initiative, a program of the 2008 Farm Bill that provides the region’s farmers with assistance to implement vital agricultural conservation practices to help clean up the Bay.
The funding will support nutrient management, cover crops, crop residue management, vegetative buffers and other agricultural conservation practices that help reduce pollution flowing into the streams, creeks and rivers that feed the Bay.
Eligible private farmland owners will receive technical and financial assistance to address wetland, wildlife habitat, soil, water and related concerns. The funding will also provide land owners with assistance to plan, design, implement and evaluate habitat conservation and restoration.
“The Chesapeake Bay Watershed initiative is an important source of technical and financial assistance to agricultural producers who want to go the extra mile to improve and protect the Bay,” said Agriculture Secretary Ed Schafer.
Farmland covers almost one-quarter of the Chesapeake watershed and is the largest single source of nutrient and sediment pollution to the Bay, contributing an estimated 42 percent of nitrogen, 46 percent of phosphorus and 72 percent of sediment annually.
The $23 million is the first part of a total of $188 million that the region will receive through the Chesapeake Bay Watershed Initiative over the next four years. This is one of the largest single federal investments in the Bay clean-up effort and an unprecedented targeting of Farm Bill resources to a specific watershed. Congress has authorized future funding levels of $43 million in 2010, $72 million in 2011 and $50 million in 2012.
USDA’s Natural Resources Conservation Service (NRCS) will administer the Chesapeake Bay Watershed Initiative. Many Chesapeake Bay Program partners, including the six Bay states and the Chesapeake Bay Commission, provided key input and information that supported the initiative’s authorization in the 2008 Farm Bill.
A new farmer-to-farmer mentoring program will help improve the economic productivity of Maryland farms and bring healthy, grass-fed livestock to local restaurants and residents – all while reducing pollution to the Bay.
The Maryland Grazers Network will help innovative farmers spread among their peers a Bay-friendly agricultural practice called rotational grazing, which involves moving livestock to different pastures once grass is grazed below a certain height. Livestock are then returned to the original pasture once grass grows tall enough to be grazed again. This process allows grass to rejuvenate and animal manure to fertilize the pasture.
The Network relies on a four-pronged approach that links:
This four-pronged approach helps improve the farmer's bottom line while reducing polluted runoff into local waterways and the Bay.
The Network was launched with eight mentoring farmers and is now soliciting new farms to join. Participating farmers receive:
The Maryland Grazers Network was established by a contribution from the Chesapeake Bay Funders Network, a funding collaborative that fosters opportunities for funders to pool resources and work together on Bay watershed restoration issues. Partners in the Maryland Grazers Network include:

Agricultural practices account for roughly one-quarter of the land use in the Bay watershed. Of that land, approximately 17 percent is devoted to crop production, which contributes significant amounts of nutrients and sediment to the Bay and its tributaries. But an increasing number of farmers in the Bay watershed are turning to a new, more Bay-friendly method of crop production called “no-till” farming.
Traditionally, cropland is fertilized and plowed in the spring to turn over the soil and prepare a good seedbed for planting. However, strong, frequent spring rains cause stormwater to rush across bare crop fields, which do not yet have plants to stabilize the soil and absorb the fertilizer. Excess nutrients and sediment from fertilizers and freshly plowed fields run off into surrounding waterways, eventually winding up in the Bay.
No-till farming, also known as conservation tillage or zero-tillage, leaves the soil undisturbed from the fall harvest to spring planting. Seeds are planted in very narrow slots that are “drilled” into the ground using disk openers, or coulters.
There are many benefits of no-till farming compared with traditional methods, including:
No-till farming is considered such a critical part of Bay restoration that several no-till programs have recently received Chesapeake Bay Targeted Watershed Grants, funded by the National Fish and Wildlife Foundation and the U.S. Environmental Protection Agency. These grants help organizations implement innovative programs to reduce the amount of nitrogen, phosphorous and sediment that flow into the Bay.
In 2006, the Pennsylvania Department of Environmental Protection - in partnership with Penn State Cooperative Extension, USDA's Natural Resources Conservation Service, the Capital Area RC&D Council, the Chesapeake Bay Foundation and the Pennsylvania Environmental Council - received a grant to oversee the conversion of 12,750 acres of cropland to continuous no-till agriculture. This conversion will reduce the annual nitrogen load to the Susquehanna River by over 99,000 pounds, and the annual phosphorous load by over 17,000 pounds.
Farmers and landowners interested in no-till farming can contact their local USDA Natural Resources Conservation Service (NRCS) office for more information.
