Turtle Island Wildlife Management Area is South Carolina's southern-most barrier island. It is situated south of Daufuskie Island and just north of the Savannah River in Jasper County. It features 2.5 miles (4.0 Km) of beach but only 120 acres of uplands. The majority of Turtle Island is tidal saltmarsh dominated by smooth cordgrass (Spartina alternaflora). The upland area is composed primarily of narrow dune ridges with some small brackish ponds scattered between the dune ridges. In addition to sea turtles, the beach is an important foraging and resting area for shorebirds.
