Elm Hall Wildlife Management Area is a two thousand eight hundred thirty-nine-acre protected wetland in Louisiana within the Atchafalaya Basin, five miles west of Napoleonville. Acquired by the Louisiana Department of Wildlife and Fisheries in 1998, it preserves a seasonally flooded cypress-tupelo swamp, adjacent bottomland hardwood forest, and important habitat for bald eagles and migratory birds while allowing regulated public recreation. The area also bears lasting effects of earlier oil and gas development, whose canals altered local hydrology and contribute to wetland degradation concerns. Reachable only by water, Elm Hall is part of broader basin conservation and restoration efforts to improve habitat connections and water flow.
