|Biosphere Reserve Information|
Ría Celestún Biosphere Reserve is located in the northwest part of the Yucatán Península, in a coastal strip that includes the limits of the Campeche and Yucatán States. It is limited to the west by the Gulf of Mexico, to the north by the El Palmar National Reserve and to the south by Los Petenes National Biosphere Reserve. Ría Celestún encompasses coastal areas of the Gulf of Mexico and includes important wetlands designated under the Ramsar Wetlands Convention.
The importance of the Biosphere Reserve is partly due to the fact that fresh water from underground aquifers has an outlet in the site, which makes the Biosphere Reserve a unique example of a natural wetland in the area. Ría Celestún is characterized by a great habitat diversity in a relatively small area: it includes several interdependent ecosystems such as a marine shallow continental platform, coastal dunes, mangroves, coastal saline and freshwater lagoons, marshlands, flood meadows, low flood forest and a strip of and low semi deciduous forest, which constitute critical habitats for a great diversity of species. The area includes 304 resident and migratory birds constituted by coastal and marshland birds such as herons (Ardeidae), ducks (Anatidae), and gulls. Ría Celestún and Ría Lagartos Biosphere Reserves are both important areas for the flamingo (Phoenicopterus ruber ruber) that nest, feed and reproduce here and whose population reaches 23,000 birds. Other bird species include the threatened plumbeous kite (Ictinia plumbea) and Brent goose (Branta bernicla), the endangered Muscovy duck (Cairina moschata), and piping plover (Charadrius melodus). The area is also of importance as a nesting site for the endangered sea turtles hawksbill turtle (Eretmochelys imbricata) and loggerhead turtle (Caretta caretta). Threatened or endangered mammal species include the jaguar (Panthera onca), ocelot (Leopardus pardalis), and Northern tamandua (Tamandua mexicana).
Ría Celestún was decreed a Natural Protected Area in 2000, with the objectives to legally conserve and protect the biological and cultural diversity, and the ecological goods and services of the ecosystems that are represented in the area. Among the priorities of the Biosphere Reserve are the management and regulation of anthropogenic activities and the promotion of a sustainable development of natural resources, that allows to improve the quality of life of the communities and to conserve the biodiversity. Some 6,700 people live in the buffer zone. At the present time, Celestún is the second fishing producer of the State of Yucatán and one of the localities with the greater population increase of the region. Three main productive activities are developed in the Biosphere Reserve, fishery, followed by salt extraction and tourist services.
