Progress

The U.S. Fish and Wildlife Service (USFWS) conducts a Mid-winter Waterfowl Survey each January to determine the abundance and distribution of several species of waterfowl. While the USFWS Division of Migratory Birds, Atlantic Flyway Council, Atlantic Joint Venture and Black Duck Joint Venture are working to revise this survey and improve abundance and distribution estimates, a rolling three-year average of pertinent survey results can be used to track progress toward this outcome.

According to survey results, an average of 51,332 black ducks were observed in Chesapeake Bay watershed states between 2013 and 2015. This marks a five percent increase from the average number of black ducks observed in the region between 2012 and 2014 and 51 percent of the 100,000 bird goal.

Once the most abundant dabbling duck in eastern North America, the American black duck has experienced a population decline as our land use has changed and its food and habitat have disappeared. Black duck abundance serves as an indicator of wetland health and food availability. The survey used to estimate the abundance of black ducks and other waterfowl is conducted on or around January 1 each year.

In recent years, black duck numbers have risen inconsistently. The mid-Atlantic region (which includes the Chesapeake Bay) supports the largest population of wintering black ducks in eastern North America. The 100,000 bird target for this outcome is based on a goal set forth in the USFWS North American Waterfowl Management Plan, which calls for a continental black duck breeding population of 640,000 birds. Preserving habitat in the Bay watershed is critical to the long-term sustainability of the species.

Management Strategy

To achieve this outcome, Chesapeake Bay Program partners have committed to:

  • Restoring historic black duck breeding or wintering habitat;
  • Enhancing and managing black duck habitat, which may include restoring riparian buffers, underwater grass beds or converted wetlands; managing open marshes and wetland water levels; and managing beavers, controlling exotic and invasive species, and performing prescribed burns;
  • Protecting black duck habitat, which may include putting conservation easements in place;
  • Managing predation;
  • Managing interspecies competition and hybridization; and
  • Reviewing and streamlining regulatory legislation and enforcement and permitting processes.

Monitoring and assessing progress toward the outcome will occur through data related to wetland conservation and the U.S. Fish and Wildlife Service (USFWS) Mid-winter Waterfowl Survey.

As part of the Chesapeake Bay Program’s partnership-wide implementation of adaptive management, progress toward this outcome will be reviewed and discussed by the Management Board in August of 2018.
