Big Branch Marsh National Wildlife Refuge is a natural treasure on the northshore of Lake Pontchartrain north of New Orleans, LA. The refuge has over 18,000 acres of freshwater and brackish marsh, bald cypress-tupelo forest, bayous, hardwood forest hammocks, and pine savannah. The refuge's marshes provide habitat for shorebirds and waterfowl, are critical spawning and nursery habitat for a number of fresh and saltwater species of fish, and help buffer local communities from storm surge. Upland habitat on the refuge provides a stopping place for migratory songbirds and a home for the endangered red-cockaded woodpecker.

      About Us

      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. Refuge habitats include lake shoreline, near shore grass beds, 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.




      Bayou Lacombe Center, the headquarters for Southeast Louisiana National Wildlife Refuges, sits on 110  acres along Bayou Lacombe. Once a horticultural attraction called Bayou Gardens, today the site hosts administrative offices for nine southeast Louisiana refuges, easy walking trails, and a Visitor Center. To reach our headquarters and visitor center from I-12, take Exit 74 and travel two miles south. From Hwy 190, we are located just north of the traffic circle at the intersection of Highways 434 and 190. The Visitor Center is open Thursdays, Fridays, and Saturdays from 9 a.m. - 4 p.m.

      What We Do

      Wildlife conservation is at the heart of what we do. It drives the work we do on lands and waters managed within the National Wildlife Refuge System, from the purposes for which a refuge is established, to the recreational activities offered, to the resource management tools used. Using conservation best practices, the Refuge System manages Service lands and waters to help ensure the survival of native wildlife species.
