Via Wildbird, I learned that the Fish and Wildlife Service has approved comprehensive conservation plans for 56 states and territories in the United States, including the District of Columbia. The plans are required by the federal government to identify declining species within each state or territory and determine what actions should be taken to prevent further decline. Completing the planning process makes each state eligible for conservation funding from the federal government.
The conservation plans for individual states are available at this website. The plan for D.C. is available here.
