About this map

Sanibel Island and its surrounding waters define this coastal study, showing the region as it transitioned into a major conservation and recreation hub in the early 1980s. The map highlights the extensive footprint of the J N (Ding) Darling National Wildlife Refuge and the Sanibel Island State Botanical Site, illustrating the prioritization of habitat preservation alongside the growth of Sanibel. At Point Ybel, the historic Lighthouse stands as a navigational sentinel where the Gulf of Mexico meets San Carlos Bay.

Beyond the residential areas of Sanibel and St James City, the map provides detailed bathymetry for the Pine Island Sound Aquatic Preserve and Matlacha Pass National Wildlife Refuge. These shallow-water environments, including Tarpon Bay and Clam Bayou, are meticulously charted with 1:100,000-scale metric contours, reflecting the complex shoals and keys like Wulfert Keys that characterize the Lee County coastline.
