Far different than the dunes along the beaches of Lake Michigan, the Florida dunes were built by Sea Oats. Tall sand dunes are not a common, natural site in Florida, but to preserve the beaches and prevent erosion, Sea Oats have been planted. Many other native plants then begin to take hold, and the dunes grow taller.
This small dune is at the extreme north end of Fort DeSoto, and sits between the Gulf of Mexico, and Mullet Key Bayou. Dense mangroves hold in the sand along the bayou shore.
