Central Florida’s extensive coastline and shallow estuaries provide ideal saltmarsh snake habitat. Average annual rainfall ranges from 45 inches (1143 mm) along the Gulf coast to over 60 inches (1524 mm) on the Atlantic side. Hot, humid summer weather fuels rapid plant growth.
Extensive salt marsh stretches along the Gulf coast around Crystal River and Homosassa. Mangrove swamps also harbor populations. On the Atlantic coast, Canaveral National Seashore and Merritt Island preserve vast saltwater marshes, tidal flats, and scrub critical for the snakes.
Urban development has reduced saltmarsh snake habitat in central Florida. However, conservation efforts protect remaining coastal wetlands. Early drainage and impoundment especially diminished marshes along the Gulf coast. Ongoing restoration aims to reestablish tidal flow and natural salinity levels to benefit marsh fauna including the saltmarsh snake.
