Sistema de Humedales Cuyamel-Omoa. 02/02/2013; Omoa, Cortes; 30,029 ha; 15°39’18” N 88°11’48.99”W. National Park. The importance of this wetlands system is based on its function as habitat of endangered species such as the Antillean Manatee (Trichechus manatus), the Jabiru bird (Jabiru mycteria), the Guasa fish(Epinephelus itajara),the crocodile (Crocodylus acutus) and the sea turtle species Dermochelys coriacea and Eretmochelys imbricate. This Ramsar Site is also vital for aquatic species particularly during their early life stages as they maintain the Mesoamerican Barrier Reef System fisheries and are the basis of the local economy. Furthermore, this wetlands system supports resident and migratory water bird populations as well as sea turtle populations that depend on the site’s beaches particularly during the spawning season. Apart from the ecosystem services already mentioned, this site is essential for the regulation of water flux and the prevention of seawater intrusion and contamination of aquifers in the coastal areas where local communities are located. Among the adverse effects faced by this Ramsar Site are the expansion of cattle ranching, the growing number of African Palm crops and the growing construction sector among others. Ramsar Site No. 2133
