The South Fenwick Island Tract is strategically located in a priority conservation area known as the ACE Basin which is a National Estuarine Research Reserve (NERR) and benefits innumerable waterfowl, wading birds, herpetofauna, migratory songbirds, and game species. The property is one of the last unprotected sea islands in the ACE Basin Focus Area. It is in the USFWS Lower Coastal Focus Area, NFWF (Forestland Stewards) Carolina Lowcountry Forests priority area, and is part of an Audubon Globally Important Bird Area. Priority habitats on the island include Spartina marsh, maritime forest, and shrub/scrub communities. Several ponds are also present throughout the island. This sea island is in the heart of the National Park Service's Gullah-Geechee Cultural Heritage Corridor and was once owned by a former slave. The island was known for its sea island cotton and indigo production.
