Chesapeake Bay Environmental Literacy Summit: Education gets outside

Nestled between Washington, D.C., and Baltimore, Maryland, the Patuxent Wildlife Research Center boasts native gardens, picturesque benches next to flowering trees that hum with bees, study sites for the center’s biologists and plenty of rivers, forests and walking trails for the public. Last Wednesday, the refuge played a role in ensuring a new generation of research scientists and nature lovers by hosting the Chesapeake Bay Program’s Leadership Summit on Environmental Literacy.

An educator from the Chesapeake Bay Foundation (CBF) shows students how to conduct a cast net survey at CBF’s headquarters in Annapolis, Md., last year. Outdoor environmental learning activities known as Meaningful Watershed Education Experiences have been shown to increase overall academic performance.

The summit centered on the environmental literacy outcome of the Chesapeake Bay Watershed Agreement, in which Bay Program partners—which include federal and state agencies, local governments, non-profit organizations, communities and academic institutions—committed to the goal to “enable every student in the region to graduate with the knowledge and skills to act responsibly to protect and restore their local watershed.”

Attendees were delegates from the education departments, environmental or natural resource departments and school districts of D.C., Delaware, Maryland, Pennsylvania, Virginia and West Virginia. Representatives from federal agencies, nonprofits, outdoor centers, and educational organizations throughout the Chesapeake Bay watershed joined in discussion and collaborated at each table. 

Remarks from Nick DiPasquale, Director of the Chesapeake Bay Program, and Brad Knudsen, Patuxent Research Refuge Manager, kicked off the day. Both began by reminiscing spending sunrise-to-sunset childhood days playing outdoors, with Knudsen expressing concern over whether today’s children would be able to do the same.

“Most kids now experience the outdoors through sports,” Knudsen said. “Sports are great, but what are the odds that at 60 they’ll still be playing soccer? If they are exposed to birdwatching, nature hikes, [nature becomes] a lifelong love and activity.”

Fourth grade students from Granby Elementary School in Norfolk, Va., learn how to measure water quality aboard the Elizabeth River Project’s Learning Barge in 2015.

To give today’s children outdoor memories and ensure a robust outdoors in which to have them, education leaders from across the watershed shared stories and discussed how to foster success in each jurisdiction. “Me – We” is the handily descriptive pronunciation for Meaningful Watershed Education Experiences (MWEE), the formal environmental education component in place in elementary, middle and high schools and which has been shown to increase overall academic performance. MWEEs—which last weeks to months and morph from classroom learning to outdoor experiences and back again—give students a sense of place within the watershed as a whole, while providing real-world applications for science, math, history, reading and art.

The afternoon concluded with attendees discussing how best to tackle environmental literacy in their particular locality. A major component of environmental literacy is establishing a sense of the full watershed. Covering some 64,000 square miles, the Chesapeake Bay watershed stretches from New York down to Virginia and includes land-locked areas of Pennsylvania and West Virginia. A school in coastal Virginia might create a Bay-focused MWEE in partnership with a local nonprofit, while a class in rural Pennsylvania might work with a local farm, a conservancy and their conservation district to develop a sense of pollution prevention and groundwater protection on their own school grounds. Watershed protection works when people understand the interworking nature of the system and decide to act locally: each area taking pride in their own land, their own streams, their local community. Environmentally literate citizens result in healthier communities; healthier local communities result in a healthier bay.

Oyster shells show evidence of early human pollution of Chesapeake Bay

Researchers studying historic pollution levels in the Chesapeake Bay found their answers in a somewhat out-of-the-ordinary subject: oyster shells. A recent study from the University of Alabama looked at nutrient levels in Bay oyster shells dating back over three thousand years, finding that humans have been polluting the Chesapeake Bay since the early 19th century.

Shells are stockpiled at the University of Maryland Center for Environmental Science's Horn Point Laboratory oyster hatchery in Cambridge, Md., on Feb. 6, 2012.

Because they live stationary lives, oysters can make useful study subjects, serving as snapshots of environmental conditions in one location. As filter feeders—they eat by pumping water through their gills—the bivalves remove nutrients from the water, absorbing much of it into their shells. This study was one of the first to use oyster shells, commonly found at archaeological sites in the region, to backdate nitrogen levels. Using that data, researchers could determine when nitrogen levels increased and what role humans may have played.

Studying oyster shells dating back to 1250 BC, researchers found a dramatic increase in nitrogen content that began in the early 1800s and increased almost exponentially until present day. That timeline corresponds what is known about human activities in the Chesapeake Bay region at that time: dramatic increases in population, agriculture and forest clearing. While American Indians altered their environment and contributed to higher nitrogen levels in the water, the effects were local. Beginning in the 17th century, an influx of European colonizers led to an increase in agriculture and forest clearing— but it wasn’t until the 19th century that human effects began to dramatically alter nitrogen levels in oysters.

Industrialization and population increases in the 1800s left their mark on the Chesapeake Bay. Between 1830 and 1880, the area’s population tripled. As a result, over 80 percent of forests surrounding the Bay were cleared for farming and development. Plowing and erosion increased the amount of sewage and sediment entering the water, increasing nitrogen levels in the water as well. Oyster populations also declined, thus limiting the ability of the Bay to filter out this influx of pollution.

While this research focused on historical nitrogen levels, nutrient pollution is still a problem in the Chesapeake Bay today. Nitrogen is necessary for plants and animals to survive, but too much of it can lead to algal blooms, which create harmful conditions for underwater life. Manure and fertilizers can wash off of agricultural fields into nearby waterways, and stormwater runoff can pick up nutrients from excess lawn and garden fertilizers, pet waste and other sources in urban areas. Chesapeake Bay Program partners work with states, local governments, farmers, businesses and many more stakeholders to implement practices that can reduce and even eliminate pollution entering waterways.

The study, “δ15N Values in Crassostrea virginica Shells Provides Early Direct Evidence for Nitrogen Loading to Chesapeake Bay,” is available online in Scientific Reports.

Photo of the Week: Terrapins take a field trip

A staff member from the National Aquarium holds a recently hatched diamondback terrapin during a visit to Poplar Island in August 2016. The turtle is one of several dozen that were raised at area schools in the Aquarium’s “Terrapins in the Classroom” program.

Through the program, hatchling diamondback terrapins (Malaclemys terrapin) are collected from Poplar Island and provided to students at Maryland schools to study and observe: monitoring their growth, examining their behavior and learning more about the species. The students grow and connect with the terrapins, while the young reptiles get an increased chance of survival.

The official state reptile of Maryland, diamondback terrapins live in the coastal marshes and mudflats of the Chesapeake Bay and its tidal tributaries. But the popularity of terrapin meat—particularly for dishes like terrapin soup—led to populations of the reptiles being decimated in the 18th and 19th centuries. Today, many regulations are in place to protect terrapins, but nest predation, loss of habitat, boat propeller strikes and entrapment in crab pots continue to threaten the turtles. Terrapins in the Classroom works to bolster terrapin populations while giving young learners a unique role in conserving the species.

In late spring each year, students travel by boat to Poplar Island—located in the middle of the Chesapeake Bay—to release the reptiles back into the marshes where they were hatched. From 2008 to 2016, more than 189 terrapins have been released into the wild.

Five ways volunteers can help protect the Chesapeake Bay

Caring for the environment is a year-round activity. But as temperatures rise, flowers bloom and the natural world springs to life, it can be easier to get outside and get involved. In the Chesapeake Bay region, there are countless opportunities to volunteer, no matter your interests or age level. April is National Volunteer Month, and to celebrate, we’re highlighting a few ways you can help protect the environment that surrounds us.

From left, Liz Stelmach, Ally Fletcher, Caleigh Fletcher and Anna Moyer combine efforts to put a large piece of pipe into a dumpster after a group of volunteers extracted it from Cat Branch Creek in Annapolis, Md., on April 11, 2015. Volunteers tackled the Cat Branch site as part of a 2015 Project Clean Stream event, removing over 4,000 pounds of trash.

1. Pick up trash
Litter is often one of the most visible forms of pollution we encounter in our day-to-day lives. Trash cleanups collect this litter—from plastic soda bottles to old tires—from sites across the Chesapeake Bay region, often along the shores of the watershed’s rivers and streams.

One of the area’s largest cleanup initiatives is the Alliance for the Chesapeake Bay’s Project Clean Stream. In 2016, close to 3.3 million pounds of trash were collected at more than 3,700 Project Clean Stream sites. While the bulk of events take place on the first Saturday in April, cleanups continue to be held through the beginning of June.

Another event, held on the first Saturday in June each year, is Clean the Bay Day. Sponsored by the Chesapeake Bay Foundation, the cleanup takes place in Virginia along the shores of the Bay and its rivers and streams. Since its start in 1989, close to 6.4 million pounds of trash have been removed from almost 6,900 miles of the state’s shorelines.

2. Plant a tree
By improving air quality, trapping water pollution and providing habitat for wildlife, trees play a critical role in a healthy ecosystem. Landowners can individually plant trees along their property, but many organizations also host tree planting events, during which volunteers can assist in planting large numbers of trees on both private and public lands.

Celebrations like Earth Day (April 22) and Arbor Day (April 28) are particularly popular for tree plantings, but events can be found throughout the spring and fall. In the Chesapeake region, April, May and October tend to be the best times for plantings, both for tree survivability and for the comfort level of volunteers working outside. To find a tree planting opportunity near you, you can contact your local watershed organization or check the events calendar of organizations like the Chesapeake Bay Foundation.

3. Be a citizen scientist
Gathering data about the natural world helps scientists and decision-makers detect changes over time and better understand the complex workings of the Bay ecosystem. But time and resources limit the number of sites and frequency of monitoring, especially in the smaller creeks and streams that thread through the region. Networks of trained volunteers can assist in activities like measuring water quality, tracking wildlife and identifying invasive species.

Organizations throughout the Chesapeake Bay region engage citizen scientists in their efforts. The Alliance for the Chesapeake Bay’s RiverTrends program, for example, provides training to water quality monitoring volunteers in the Virginia portion of the Bay watershed. Other initiatives like Project Noah use mobile apps to track sightings of wildlife. Contact your local watershed organization to learn about citizen science opportunities in your area.

4. Support wildlife
Hundreds of species depend on the Chesapeake Bay and its surrounding region, whether as seasonal visitors or as permanent residents. A variety of factors affect the ability of these critters to thrive, from the availability of sufficient food and habitat to surviving in a world of unfamiliar, man-made obstacles. Wildlife organizations and refuges provide support and sanctuary to thousands of animals each year, and they rely on volunteers to help carry out their mission.

Organizations like the Wildlife Center of Virginia assist in wildlife rehabilitation, using volunteers to transport, treat and care for injured wildlife. Volunteers help City Wildlife in D.C. care for urban wildlife, track injured migratory birds and monitor duck nests in the city.

The Chesapeake Bay watershed is also home to fifteen national wildlife refuges, protecting the forests, fields, wetlands and shorelines that wildlife depend on. Many of these refuges have “Friends” groups—such as Friends of Blackwater National Wildlife Refuge—that provide volunteer opportunities like leading nature walks, helping with trail maintenance and staffing information desks.

5. Educate others
More than three million students in kindergarten through 12th grade live in the Chesapeake Bay watershed—and soon, they’ll be the caretakers of its well-being. Teaching these students the knowledge and skills they need to care for the natural world builds the foundation for future environmental stewardship.

That’s why groups across the region are focused on providing meaningful outdoor experiences to students, connecting them with the environment that surrounds them. Audubon Naturalist Society near D.C., for example, uses volunteer teaching assistants to help lead lessons about planting trees or stream science. And volunteers can help the Sultana Education Foundation on the Bay’s Eastern Shore by both leading environmental education programs and working aboard the organization’s replica 1768 Royal Navy schooner.
