Description - The Mark Twain National Wildlife Refuge Complex was established for the protection of migratory birds including waterfowl, shorebirds, and songbirds. It is located along the Mississippi Flyway, one of the major routes for migrating waterfowl. Refuge units also provide important habitat for big river fish and a variety of other native wildlife such as deer, fox, beaver, frogs, turtles, and snakes. Key goals are to conserve and enhance the quality and diversity of fish and wildlife and their habitats, to restore floodplain functions in the river corridor, and to provide wildlife-related recreational experiences for the public.
- Located within the Mississippi Flyway, one of the nation's most important flyway routes, Mark Twain NWR provides waterfowl and other migratory birds with food, water and protection during the spring and fall migrations.
The Refuge is separated into three Districts and a headquarters in Quincy, Illinois.
The Annada District consists of the Clarence Cannon NWR and the Delair, Gardner, Harlow Island and Gregory Landing Divisions of Mark Twain. The District contains some of the last remaining large contiguous stands of bottomland hardwoods in the area.
