We work with landowners, private and community organizations, government agencies and others to conserve, protect and enhance fish and wildlife in the Chesapeake Bay area including Delaware, Maryland and the District of Columbia. Our conservation priorities include: endangered, threatened and at-risk wildlife; migratory birds and fish; pollinators; and wetland, coastal, riparian and upland habitats.

Projects and Research

Our office works with private landowners and other partners to restore or enhance wetland, upland, riparian riparian
Definition of riparian habitat or riparian areas.

 and instream habitats for threatened, endangered and at-risk species. We work to recover populations of plants and animals listed under the Endangered Species Act such as the eastern black rail, red knot, bog turtle, Puritan tiger beetle, dwarf wedgemussel, Indiana bat, northern long-eared bat and small whorled pogonia. We connect communities to nature through broad-based initiatives like Baltimore Rivers to Harbor Urban Refuge Partnership and provide landscape level conservation through the Delmarva Conservation and Restoration Network and Chesapeake Bay Nutria Eradication Project. We help to reduce energy impacts to wildlife through recommendations of best management practices. We manage wildlife habitat at beneficial dredge material sites such as Poplar Island and Masonville Cove.
