Nahshon Forde, an operations assistant with the Anacostia Watershed Society, steers his kayak to shore after helping with a free paddle night organized by the AWS in Washington, D.C. "By doing paddle nights and things like that we’re helping people develop a relationship with the river, and that’s kind of a conveyor belt to a lot of our other ways to be involved with AWS," said Lee Cain, Director of Recreation at AWS.
Historically overrun with pollution, the Anacostia is still plagued by litter, toxics and stormwater runoff. But the river is also home to a wealth of wildlife: deer silently approaching the water’s edge, egrets congregating in the shallows and bald eagles defending their nests.
In June 2014, the Anacostia Water Trail officially opened. This nine-mile water trail runs from Bladensburg, Maryland, through Washington, D.C., to where the Anacostia meets the Potomac River, passing by natural areas and recreation sites like Kenilworth Park, the National Arboretum, Kingman Island and Yards Park.

According to fisheries experts, the Chesapeake Bay blue crab stock is not depleted and overfishing is not occurring. Nevertheless, experts recommend maintaining a risk-averse, or cautious, approach to blue crab management: just two years ago, adult female blue crabs were considered depleted. Even after a 183 percent rise in their population between 2014 and 2016, their numbers remain below target levels.
The 2016 Chesapeake Bay Blue Crab Advisory Report was released by the Chesapeake Bay Stock Assessment Committee (CBSAC). It includes blue crab population and harvest data from Maryland, Virginia and the Potomac River Fisheries Commission, as well as expert recommendations on maintaining a sustainable blue crab fishery.
According to the report, the start of the 2016 crabbing season saw an estimated 194 million adult female blue crabs in the Bay. This marks a 92 percent increase from last year’s abundance of adult females, which the Chesapeake Bay Program tracks as part of its progress toward the goals and outcomes of the Chesapeake Bay Watershed Agreement. Because adult female blue crab abundance is above the 70 million threshold, the blue crab stock is not considered depleted. And because just 15 percent of adult females were harvested in 2015—well below the 25.5 percent target—overfishing is not occurring.
“The blue crab population is at a healthy level,” said Maryland Department of Natural Resources Biologist and CBSAC Chair Glenn Davis in a media release. “It is encouraging to see adult females rebound from a depleted state… but that also serves as a reminder of how quickly things can change with this animal.”
In its report, CBSAC—which includes scientists and representatives from state agencies and academic institutions, as well as federal fisheries experts—recommends the improvement of harvest and fishing effort estimates, the jurisdictional coordination of complementary management measures and the evaluation of an allocation-based blue crab management framework. An allocation-based management framework would allocate an annual total allowable catch (TAC) of blue crabs for the Bay’s commercial and recreational fisheries among its three management jurisdictions: Maryland, Virginia and the Potomac River Fisheries Commission. The report recognizes the importance of future stock assessments in providing in-depth scientific guidance to support blue crab management.
“It’s great to see that the Chesapeake Bay blue crab population has increased over the past two years and we are close to achieving the target of 215 million adult female blue crabs outlined in the Chesapeake Bay Watershed Agreement,” said National Oceanic and Atmospheric Administration Chesapeake Bay Office Director and Sustainable Fisheries Goal Implementation Team Chair Peyton Robertson in a media release. “The annual Advisory Report continues to provide valuable counsel for jurisdictional fishery managers as they work toward sustaining the blue crab population at that level over the long term.”
For more than a century, the United States has worked to protect the wilderness around us with parks, preserves and sanctuaries. While natural spaces of all shapes and sizes can benefit wildlife, only one government-designated wilderness program was established in order to build a network of wildlife habitat: the national wildlife refuge system.
The first national wildlife refuge was established in 1903. Today, there are more than 560 wildlife refuges in the nation, whose 150 million acres of land and water are managed by the U.S. Fish and Wildlife Service and marked with the emblem of a flying blue goose. Fifteen wildlife refuges are located in the Chesapeake Bay watershed, protecting forests, fields, ponds, marshes, swamps and shorelines in Maryland and Virginia. Federally owned land—which includes wildlife refuges—accounts for about 26 percent of the 8.37 million protected acres in the region, and is integral to our work to safeguard wildlife habitat from development. Learn about five wildlife refuges in the watershed below.
1. Eastern Neck National Wildlife Refuge (Rock Hall, Md.). Established in December of 1962, this 2,285-acre island refuge is located where the Chester River meets the Chesapeake Bay. The island was among the first parts of Maryland to be settled by European colonists: between 1658 and 1680, two men acquired the entire island tract by tract. Today, the island’s forests, grasslands, ponds and tidal marshes offer critical feeding and resting grounds to hundreds of species of migratory birds. Ducks, swans and geese are particularly abundant in late fall and early winter, and refuge staff have documented peaks of more than 50,000 waterfowl at one time on or near the refuge. The refuge provides visitors with opportunities to walk and bike, view wildlife, boat, fish, crab and hunt for turkey and white-tailed deer.
2. Patuxent Research Refuge (Laurel, Md.). Established in December of 1936, this refuge has expanded from its original 2,670 acres to encompass more than 12,800 acres between Baltimore and Washington, D.C. It is the only wildlife refuge established to support wildlife research. The Patuxent Wildlife Research Center is operated by the U.S. Geological Survey, whose staff specialize in research related to wildlife and natural resources science, from the status and trends of bird populations to the effects of chemical contaminants on wildlife. One of its most famous programs involves the captive breeding of whooping cranes: biological technicians raise more than 30 chicks each year, releasing most to a non-migratory flock in Louisiana and training the rest to migrate from Wisconsin to Florida. While the grounds that house the research center are not open to the public, the refuge’s North Tract and impressive National Wildlife Visitor Center provide visitors with opportunities to walk, view wildlife, fish and hunt.
3. Eastern Shore National Wildlife Refuge (Cape Charles, Va.). Established in 1984 to promote migratory and endangered species management, this 1,123-acre refuge located at the tip of the Delmarva Peninsula was once a military fort. During World War II, Fort John Custis protected naval bases in Virginia Beach and Norfolk. In 1950, the U.S. Air Force took ownership of the fort, renamed it the Cape Charles Air Force Station and occupied the area until 1981. Today, the refuge is valued as one of the most important stopover sites for migrating birds and butterflies in the nation. Each fall, songbirds, raptors and monarch butterflies gather at the refuge to feed and rest before resuming their migrations south. More than 400 bird species have been seen in and around the refuge, and on peak days, 100,000 monarch butterflies have been seen on refuge roosts. The refuge’s wood- and shrublands, fields, ponds and marshes are also valuable to insects (including the endangered northeastern beach tiger beetle), mammals and other critters. The refuge provides visitors with opportunities to walk, view wildlife, boat and hunt for white-tailed deer.
4. Elizabeth Hartwell Mason Neck National Wildlife Refuge (Lorton, Va.). Established in February of 1969, this 2,227-acre refuge sits on a boot-shaped peninsula between the Potomac and Occoquan rivers. While an airport and residential community were planned for the land in the early 1960s, local resident Elizabeth van Laer Speer Hartwell launched a campaign to halt the development and protect the bald eagles that called the Potomac River home. As a result, this refuge—located just 18 miles south of Washington, D.C.—became the first that was established for the explicit protection of the bald eagle and one of four named after women. It encompasses almost six miles of shoreline, 2,000 acres of mature hardwood forest and 207 acres of tidal freshwater marsh that is home to a large breeding colony of great blue herons. The refuge provides visitors with opportunities to walk, view wildlife and hunt for white-tailed deer.
5. Rappahannock River Valley National Wildlife Refuge (Warsaw, Va.). Established in 1996, this refuge is the newest of four that compose the Eastern Virginia Rivers National Wildlife Refuge Complex. While it currently consists of 8,720 acres of forests, grassland, marshland and swamps, the U.S. Fish and Wildlife Service hopes to protect 20,000 acres of habitat along the Rappahannock and its tributaries over time. The refuge is home to breeding bald eagles and migrating birds, and provides visitors with opportunities to walk, view wildlife, boat, fish and hunt for white-tailed deer.
Lightning strikes, signaling a coming storm at Schrack Dairy Farm in Loganton, Pennsylvania. Owner Jim Harbach practices no-till farming—a method that leaves the soil undisturbed from the fall harvest to spring planting—along with other sustainable efforts to improve soil quality on the farm that has been in his wife's family for 12 generations, since 1773. Close to one-quarter of the land in the Chesapeake region is used for agricultural production, providing us with food and fiber, natural spaces and a multitude of economic and environmental benefits.
But agriculture is also the largest source of nutrient and sediment pollution entering the Bay’s waters. Over-irrigating farmland, over-tilling soil and over-applying fertilizers and pesticides can push pollution into local waterways. Agricultural “best management practices,” or BMPs, are tools that farmers can use to reduce the runoff of pollution. Techniques like cover crops help prevent soil erosion, while streamside forest buffers can slow polluted runoff, stabilize stream banks and provide habitat for wildlife.
