From Ramsar

Protected area. Located on the southeastern coast just offshore from the capital Kingston, the site contains cays, shoals, mangrove lagoons, mangrove islands, coral reefs, seagrass beds and shallow water, thus hosting a variety of underrepresented wetland types. Endangered and vulnerable species occurring in the area include American crocodile (Crocodylus acutus), green turtle (Chelonia mydas), Hawksbill turtle (Eretmochelys imbricata), West Indian manatee (Trichechus manatus) and bottlenose dolphin (Tursiops truncatus). To date 26 endemic new species have been discovered in the area. Historic and cultural values are very high, as the site includes forts on the dunes and part of the city of Port Royal, said to have been the largest city in the Americas, which sank in an earthquake in 1692 and is now a unique archaeological treasure. A management plan is in place, and the University of the West Indies operates research facilities.
