A coastal and marine reserve located in the north of the Yucatán Peninsula, adjacent to the Ría Lagartos Ramsar site. The site includes a unique hydrological system, "anillo de cenotes", a formation caused by the impact of a huge meteor. This site comprises various habitats: marine areas of the continental platform, seagrass beds, intertidal lagoons, sandy dune shores, flooded jungle, dry low jungle and medium height jungle. The site provides important habitat for more than 20,000 waterbirds, such as the Mexican pink flamingo and many other migratory species. It is also an important habitat for a wide diversity of species and life history stages of fish, molluscs and crustaceans, some of them with a high commercial value, and it provides habitat for several endemic, threatened and endangered species of cactus, reptiles and amphibians. The site has extremely important cultural values, as it was an area of residence of prehispanic cultures. 14,000 hectares of the site belong to private landowners. About 68% of the population residing in the area derive their livelihoods from fishing, hunting and agriculture, 8.5% from trade, 7.5% from industry, 4% from tourism, and the rest work for the government.
