History, wildlife, and the wild beauty of one of America's most treasured coastal ecosystems.
The ACE Basin — named for the three rivers that define it, the Ashepoo, Combahee, and Edisto — is one of the largest undeveloped estuaries on the entire East Coast of North America. Nestled within Colleton, Beaufort, and Charleston counties of South Carolina, this extraordinary landscape spans over 350,000 acres of tidal marshes, bottomland hardwood forests, upland longleaf pine savannas, and ancient rice field impoundments.
What makes the Ace Basin truly special is what didn't happen here. As development overtook much of the Atlantic coast, a unique coalition of private landowners, conservation organizations, and government agencies joined forces in the 1980s to protect this area through voluntary conservation easements. The result is a vast, living landscape that looks much as it did when European explorers first paddled these tidal creeks centuries ago.
The ACE Basin National Wildlife Refuge, established in 1990, anchors the larger ACE Basin Project — one of the most successful voluntary land conservation initiatives in American history.
The Ace Basin supports an astonishing variety of wildlife. From the smallest seaside sparrow to the great American bald eagle, the basin is home to species both common and rare.
Long before European contact, the Ace Basin was home to the Cusabo people, a confederation of Native American tribes who lived along its rivers and tidal creeks for thousands of years. The abundance of fish, shellfish, deer, and wild plants made this landscape one of the richest environments on the continent.
European colonization brought profound change. By the mid-1700s, the region had become one of the most productive rice-growing areas in colonial America. Enslaved Africans — many brought specifically from rice-growing regions of West Africa — built the elaborate system of dikes, canals, and floodgates that turned the low-lying marshes into productive rice fields. This brutal but sophisticated agricultural system shaped the physical and cultural landscape of the Ace Basin for generations.
After the Civil War, many of the great rice plantations fell into decline, and the old fields slowly reverted to wetland habitat — inadvertently creating some of the finest waterfowl habitat on the East Coast. These impoundments, managed today for wildlife, are a central feature of the ACE Basin National Wildlife Refuge.
The Gullah Geechee culture — the descendants of enslaved Africans who built and sustained the Lowcountry economy — remains a living, vibrant presence in the region. Their language, food traditions, basket weaving, and spiritual practices represent a unique and irreplaceable piece of American heritage. Organizations throughout the region work to preserve and celebrate this culture.
The Ace Basin puts you within easy reach of some of South Carolina's most charming and historic communities.
