The Mississippi Sound and the Gulf of Mexico are separated by a chain of barrier islands. The easternmost of these, Dauphin Island, lies at the mouth of Mobile Bay in Mobile County, Alabama. It is situated between Fort Morgan to the east and Petit Bois Island to the west. The island is approximately six miles south of the mainland coast. The elevation of the island ranges from sea level to approximately 50 feet on the back dunes of the south-facing beach.
In the 1960's I undertook a floristic survey, photographing many of the plants occurring on the island at that time---this website is devoted to those photographs, showing habitats as well as individual plants and flower close-ups.
