Grand Bay National Wildlife Refuge is located in coastal Mississippi and Alabama. The refuge was established in 1992 to help protect one of the largest remaining expanses of Gulf Coast wet pine savanna habitat.
The 10,188 acre refuge partially overlays the Grand Bay National Estuarine Research Reserve. Together, they protect nearly 18,000 acres of relatively undisturbed wildlife habitat.
In addition to the wet pine savanna, other refuge habitats include maritime forest, tidal and nontidal wetlands, salt marshes, salt pannes, bays and bayous.
The Grand Bay NWR is part of the Gulf Coast National Wildlife Refuge Complex, which includes Mississippi Sandhill Crane NWR (MS) and Bon Secour NWR (AL).
