Parque Nacional Isla Contoy. 27/11/03; Quintana Roo; 5,126 ha; 21°29'N 086°47'W. National Park. One of the northernmost islands in the Mesoamerican Barrier Reef, 50km north of Cancún and 13km off the mainland Yucatán peninsula, the principal nesting site for seabirds in the Mexican Caribbean. Coastal dunes, mangroves, lagoons, low forest and coconut palm trees dominate the terrestrial landscape of the island, while marine environments include sea-grass beds and coral reefs. Marine fish stocks are significant due to the abundance of plankton provided by the upwelling of cold submarine currents. Mammals are notably absent from the island. The endangered Green, Loggerhead, Hawksbill and Leatherback turtles nest on Isla Contoy, as well as the Horseshoe Crab Limulus polyphemus and large colonies of Magnificent Frigatebird Fregata magnificens, Double-crested Cormorant Phalacrocorax auritus and Brown Pelican Pelecanus occidentalis. A management plan regulates lobster fishing, sports fishing and tourist activities, and there is a fully equipped visitor and information centre. Rapid tourist development on the mainland coast poses threats to the island, as well as hurricanes such as Isidore in 2002. Ramsar site no. 1323. Most recent RIS information: 2003.
