SIAN KA'AN

 
       
  General Description   Situated on the Caribbean coast in the southeast of the country, on the eastern side of the Yucatan Peninsula in the State of Quintana, the reserve lies on a partially emerged coastal limestone plain, and includes part of the extensive barrier reef system.. It is covered by medium altitude semi-evergreen forests, medium and low altitude semi-deciduous forest; palm savannah formations, freshwater and saltwater marshes, petenes (or hammocks), mangroves and, dunes. A total of 4,000 plant and 28 mammal species have been recorded, including five species of cat, jaguar, puma, Central American tapir and Caribbean manatee. Due to the great diversity of aquatic habitats, marine and wading birds are well represented. Twenty-three Mayan sites have been recorded in the reserve, while Tulum, one of the most visited Mexican archaeological sites, the Chunyaxché ruins, Vigia del Lago and Xamach, are just to the north. There are 800 inhabitants (1999) mainly of Mayan origin, living in the reserve and practicing subsistence agriculture, and fishing, . The reserve is subject to important pressures from tourism, immigration and colonization. Research is focusing on basic science and its application to the management and conservation of natural resources. El Ramonal experimental plot has been used to develop agricultural techniques that preserve the delicate Yucatan soil, using mixed cropping and crop rotation. Twinned with Guanahacabibes Biosphere Reserve in Cuba, it is also envisaging an agreement with the Everglades National Park in the USA.
