Welcome to the
Georgia Coast Atlas

The Georgia coast, approximately 100 miles long, is defined by its barrier islands and their back-barrier environments. With a variety of life in maritime forests, salt marshes, tidal channels and creeks, back-dune meadows, coastal dunes, beaches, and offshore environments, the barrier islands and their back barrier environments are biologically rich. The seasonally subtropical climate of the islands, combined with large tidal fluxes, helps make Georgia salt marshes among the most biologically productive ecosystems in the world. The Georgia coast also holds nearly one-third of the salt marshes in the eastern U.S.
