 Perdue UnitThe west end of Little Lagoon is surrounded by the Perdue Unit of the Bon Secour NWR established in 1980 to protect threatened species. Its interior habitats include scrub forest, fresh and saltwater marshes and swamps, as well as uplands that provide for migratory birds species, alligators, red fox, coyotes, and armadillos, among other species.  Its beaches serve as nesting sites for loggerhead and other sea turtles, and its sand dune habitats are home to the endangered Alabama beach mouse. |  |
