ACE Basin National Estuarine Research Reserve

One of the largest undeveloped estuaries on the east coast, South Carolina’s ACE Basin reserve is named for the Ashepoo, Combahee, and Edisto Rivers, which meet at St. Helena Sound. The reserve’s 99,308 acres of pine and hardwood uplands, forested wetlands, tidal marshes, cypress swamps, oyster reefs, and barrier islands protect endangered species such as shortnose sturgeon, wood storks, loggerhead sea turtles, and bald eagles. Reserve staff and the South Carolina Department of Natural Resources work together to restore oyster reefs along tidal marshes. These living shorelines help protect coastal communities and keep waterways clean and healthy.
