Island Bay Wilderness

The tangled masses of roots stemming from mangrove trees often intertwine to form islands, a haven for pelicans, herons, and egrets. The four small mangrove islands and two small mangrove points were given protected status by President Theodore Roosevelt when they became what is now known as Island Bay National Wildlife Refuge. J. N. "Ding" Darling National Wildlife Refuge now manages the refuge. The Island Bay Wilderness was established as one of the smallest units in the National Wilderness Preservation System. Several shell mounds pay tribute to the Native Americans who once called the area home.
