Big Branch Marsh National Wildlife Refuge

Fish and Wildlife Service, Louisiana.

Big Branch Marsh National Wildlife Refuge, established in 1994, is located along the north shore of Lake Pontchartrain between the towns of Mandeville and Slidell, in St. Tammany Parish, Louisiana. This refuge is the indigenous homeland of the Acolopissa and Choctaw people, whose descendants are present in the region today. Refuge habitats include lake shoreline, freshwater and intermediate marsh; bald cypress-tupelo forest; bayous; hardwood forest hammocks; and long-leaf pine savannah. These habitats support freshwater and marine fish, shorebirds, wading birds, seventeen species of wintering migratory waterfowl, neotropical songbird migrants and the endangered red-cockaded woodpecker.
