Bogue Chitto National Wildlife Refuge is one of the most undisturbed wild swamplands in the country. Unique plant and animal communities adapted to the seasonal floods of the Mississippi Delta area thrive here. The river system supports the threatened ringed sawback turtle - a unique reptile found only in the Pearl River and its major tributaries in Louisiana and Mississippi. The refuge also supports the Gulf sturgeon, an anadramous “living dinosaur” that can reach lengths of up to nine feet and weigh up to 300 lbs. Upland acres of loblolly and slash pine forest provide habitat for the threatened gopher tortoise.
