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.
The refuge conserves a significant remnant of natural habitats that support wildlife within the rapidly urbanizing Lake Pontchartrain Basin. As one of the last remaining undeveloped, contiguous tracts of wildlife habitat in the region the refuge provides broad opportunities for public use. From fishing in the bayous, waterfowl hunting in the refuge’s marshes, paddling the bayous, to birding and wildlife photography - experiencing the refuge’s natural beauty connects us with our priceless natural heritage and replenishes the spirit.
Prior to refuge establishment in 1994, wetlands north of New Orleans were rapidly disappearing as urban expansion occurred. Several local organizations — including Northshore Coastal Watch, St. Tammany Sportsman’s League, the Coalition to Restore Coastal Louisiana and the Lake Pontchartrain Basin Foundation — recognized the importance of these coastal habitats to the health and economy of the region and initiated a community effort that led to purchase of the land and the establishment of the refuge.
