Passage Key Wilderness

A violent hurricane swept through this area in 1920, transforming Passage Key, a mangrove island containing a freshwater lake, into a meandering, slightly vegetated sandbar. Situated within one of three refuges comprising the Tampa Bay Refuges, Passage Key Wilderness stands at the mouth of Tampa Bay, where it faces the full force of storms off the gulf. In the last few years, erosion has erased most of the island. At low tide, small portions of the island will still occasionally rise above the waterline. This one island represented Tampa Bay's last remaining nesting site for laughing gulls, black skimmers, and royal terns. However, with no more land being above water on a regular basis, there is no more bird breeding on the island.
