Lagunas de Chacahua. 02/02/08; Oaxaca; 17,424 ha; 16°00'N 097°40'W. Natural Protected Area, turtle sanctuary. A coastal lagoon system and a sandy beach facing the Pacific Ocean. It is distributed in low lands associated with alluvial, fluvial and deltaic plains, low intertidal marshes, and highlands up to 140m asl. These water bodies are home for several species such as the Crocodile (Crocodylus acutus) that are under special protection, and fish species such as Centropomus nigriscens and Centropomus robalito. The beach portion of the site is a nesting ground for three marine turtles, especially the endangered Leatherback Turtle (Dermochelys coriacea). The site is also important for many resident and migratory bird species. The mangroves are a source of food and refuge for many birds, mammals, reptiles, among others. Fishing is the main human activity of the site, and the main potential threat is caused by the rapid population growth in its surroundings. The site has been a Natural Protected Area since 1937 and part of the Playa de la Bahía de Chacahua Sanctuary for the protection of marine turtles since 1986. Ramsar site no. 1819.
