Photo of the Week: Protecting the home of the American black duck

Hutch Walbridge, Wildlife Biologist with the Maryland Department of Natural Resources, places an identification band on the leg of a female American black duck on a farm in Church Creek, on Maryland’s Eastern Shore, on March 5, 2013.

Not truly black, the dark, dusky-brown plumage of the American black duck (Anas rubripes) appears black from a distance. This shy, native waterfowl can be found year-round along the quiet, isolated tidal wetlands of the Chesapeake Bay and its rivers. When food sources in the north become scarce in colder months, additional ducks migrate to the Bay region to overwinter.

Black ducks were once the most abundant dabbling duck in eastern North America. But as the Bay’s wetlands disappeared, black duck populations dropped dramatically. In the 1950s, close to 200,000 black ducks spent their winters in the Chesapeake Bay region. But recent estimates show that, from 2013 and 2015, just over 51,000 black ducks overwintered on the Bay each year.

Marshes and wetlands in the Bay region are critical to the long-term survival of the black duck. Protection of the area’s remaining tidal marshes—along with large-scale habitat restoration projects like Poplar Island—helps provide the birds with the habitat and food sources they need. Under the Chesapeake Bay Watershed Agreement, our partners are working toward having enough habitat to support 100,000 wintering black ducks by 2025.

Chesapeake Bay Foundation reports modest improvement in Bay health

The Chesapeake Bay Foundation has reported a modest improvement in Chesapeake Bay health since 2014. The nonprofit gave the estuary a grade of “C-” in its biennial State of the Bay report, noting reductions in water pollution and increased abundance of blue crabs, oysters and other fisheries.

The score of 34 on a one-to-100 scale marks an improvement of two points from the 2014 report—which gave the Bay a “D+” grade—but remains well short of the Foundation’s goal of 70, representing an “A+” or a “saved Bay.”

According to the report, nine of the 13 indicators of Bay health showed signs of recovery, including dissolved oxygen, water clarity, underwater grass abundance and populations of blue crabs, striped bass, oysters and shad. Of those indicators, blue crabs showed the greatest improvement, with the number of adult crabs having roughly tripled since 2014. Three of the indicators—toxic contaminants, wetlands and resource lands—showed no change from the previous report, and one indicator, forest buffers, declined.

The report attributed improvements in water quality in part to continued implementation of the “Clean Water Blueprint,” or Chesapeake Bay Total Maximum Daily Load—a comprehensive plan to reduce pollution going to the Bay and its rivers and streams.

The Chesapeake Bay Program will publish Bay Barometer, its annual snapshot of watershed-wide health and restoration, later this month. The Bay Program is a voluntary partnership that includes the six watershed states of Delaware, Maryland, New York, Pennsylvania, Virginia and West Virginia; the District of Columbia; the Chesapeake Bay Commission; and the U.S. Environmental Protection Agency representing the federal government.

Photo of the Week: A hopeful recovery for striped bass

Captain Pete Ide throws a freshly caught striped bass onto the dock in Chesapeake Beach, Maryland, after a charter fishing excursion on the Chesapeake Bay on November 11, 2016.

For hundreds of years, striped bass—also known as rockfish or stripers—have been one of the most popular commercial and recreational fish in the Chesapeake Bay, which is the largest striped bass nursery area on the Atlantic coast. Experts estimate that up to 90 percent of the Atlantic striped bass population uses the Bay and its tidal tributaries to spawn.

In the early 1970s, the striped bass industry experienced record-high catches: in 1973, the commercial fishery landed 14.7 million pounds. But in the years that followed, commercial and recreational catches declined steeply, and by 1983, the harvest had fallen to just 1.7 million pounds. Scientists attributed the sharp decline primarily to overfishing, which may have made the striped bass more susceptible to stressors like changes in water temperature, low dissolved oxygen, chemical contaminants and poor water quality.

After fishing moratoria throughout the late 1980s in Delaware, Maryland and Virginia, the Chesapeake Bay striped bass fishery re-opened in 1990. Since then, striped bass abundance in the Bay has dramatically increased. According to the Atlantic States Marine Fisheries Commission, in 2015, the biomass of adult female striped bass along the Atlantic Coast was estimated to be 129 million pounds—above the overfishing threshold of 127 million but below the target of 159 million pounds. And while results of Maryland’s 2016 juvenile striped bass survey were well below the long-term average, scientists expect successful spawning years in 2011 and 2015 to compensate for the below-average year.

Restoration Spotlight: Near a historic quarry, volunteers carve their niche

In 1791, a small island on Aquia Creek in Stafford County, Virginia, began sending its warm-colored sandstone downstream to the Potomac River, where schooners and sloops would haul it upstream to Washington, D.C. The stone, well-suited for intricate carving, was destined to be part of the White House, the Capitol Building and many other landmarks of our nation’s capital. Unused since the 1800s, Public Quarry at Government Island is now a historic nature preserve on the National Registry of Historic Places.

The 1.5-mile trail to Government Island follows Austin Run, a stream that flows into Aquia Creek. On a December weekend, visitors walked the trail through woods and wetlands of 17-acre Government Island Park before taking a looping path around the island. A well-dressed family with a photographer in tow and a couple of teenage girls stopped periodically to take portraits against the natural scenery.

Andrea Black, left, and Mary Haq of Green Aquia conduct water quality monitoring at Austin Run, which flows into Aquia Creek in Stafford County, Va., on Dec. 3, 2016. Green Aquia focuses on promoting a low environmental footprint through activities such as the monthly monitoring, creek cleanups and a community garden.

Nearby, a group of trained citizen scientists from a community service organization called Green Aquia conducted their monthly water quality monitoring effort at six points along Aquia Creek and Austin Run. The volunteers are residents of Aquia Harbour, a private community of almost 7,000 people that straddles the creek.

“We have a group of probably six to eight people who are very consistent with helping monitor these locations,” said Andrea Black, who is vice president of Green Aquia and in charge of their water quality monitoring program.

The water quality data is sent to the Alliance for the Chesapeake Bay as part of its RiverTrends program. The Alliance provides training to monitoring volunteers and submits the data to the Virginia Department of Environmental Quality (DEQ), for use in reports to the Environmental Protection Agency.

Through its monitoring, Green Aquia identified high levels of E. coli in Austin Run four years ago, and took action to stop the bacteria at its presumed source—horse manure from stables nearby. The group petitioned Aquia Harbour’s board of directors to assess the situation. Aquia Harbour switched their manure storage from an open pit to a covered structure, paid for by funds raised through a recycling program Green Aquia established.

Black said that Austin Run now yields lower E. coli numbers.

“We noticed a dramatic change in the quality of the water that was coming from the checkpoint that’s behind [the stables],” Black said. “The water is better.”

Sandstone on Government Island still shows the marks of quarry tools. The site, known as Public Quarry, was purchased by the federal government in 1791 to supply stone for the White House and other buildings in Washington, D.C.

At the same time that increased access to Government Island has allowed Green Aquia to pay more attention to the park’s issues, the additional foot traffic has been a challenge in and of itself.

“The park itself is becoming more popular, so you have more people walking the trails,” said Mary Haq, another member of Green Aquia. “And they don’t always stay on the trails.”

Maria Cannata, a Master Naturalist and member of Green Aquia, said the amount of storms and debris snagging on a new bridge have increased erosion.

Maria Cannata of Green Aquia points out sand bars that have formed from erosion along Austin Run in Government Island Park in Stafford County, Va., on Dec. 3. “This creek was much narrower four years ago and the erosion has just taken it all out and made all these little islands,” Cannata said.

“Dead trees will come down and they’ll block the pilings here, and create a logjam and then collect more debris. So it reroutes the water,” Cannata said.

Near the park tables where the volunteers finished some of their water tests, thick stumps riddled with insect galleries are the remains of large ash trees killed by the larvae of the emerald ash borer, an invasive species.

“In that grove there you can see a lot of dead ash trees,” Cannata said. “They get very brittle when they’re dead and they snap.”

Cannata remembers a phenomenal rise in woodpecker activity due to the ash borer when it swept through two years ago.

“Woodpeckers, all in this park, just getting fat and happy ripping the bark off to get the insects out.” Cannata said. “You’d walk through the park and the bark would be flying on you and it would be all over the walkway.”

Walking into Government Island Park after finishing most of the water monitoring, Black, Haq and Cannata passed underneath power lines and recounted another victory for the park and for Austin Run.

Government Island Park is a 17-acre nature preserve with a scenic heritage trail in Stafford County, Va. The park is on the National Register of Historic Places and the Virginia Landmarks Register.

After noticing a crew spraying pesticides along the utility right-of-way, Green Aquia worked out an agreement with Dominion Virginia Power. Now, once a year, volunteers maintain trees below a specified height, so that the utility can reduce their use of pesticides at the park. The same day as the December monitoring effort, Green Aquia had several volunteers spending a few hours cutting saplings.

Continuing deeper into the park, the three volunteers lamented a decline in wildflowers in the woods along Austin Run in recent years, and a troubling shift from a plant called spatterdock, which needs deeper water, to wild rice in the wetlands in front of Government Island.

But on Government Island itself, some things have changed more slowly. The monolithic slabs of sandstone still show the marks of cutting tools made in the mid-1800s. Nearby, an original boundary marker, complete with the carved initials of the owner, marks what had been a one-acre property purchased in 1786.

Fighting off the late fall chill, Black, Cannata and Haq started heading back to their vehicles, taking turns riffing on the unsightliness of pet waste left in bags along the trail—and sometimes thrown into trees.

But their focus quickly changed to the sight of a hairy woodpecker flitting from one bare trunk to another, lingering long enough for the group to stop and admire.

After a moment, a father and son who had been following the same boardwalk caught up to the group. The father crouched to toddler level, whispering to his son, and the family stopped to watch the bird too.
