      Biosphere Reserve Information



  General Description   La Encrucijada Biosphere Reserve is situated in the Pacific Coastal Lowlands physiographic region. It covers 144,848 ha stretching over six municipalities in the Costa de Chiapas (Pijijiapan, Mapastepec, Acapetahua, Villa Comaltitlan, Huixtla and Mazatan). It is composed of two large coastal lagoon systems that correspond to two core areas (La Encricijada and Palmarcito), and a wide variety of natural ecosystems including mangroves, zapotonales, tule swamps and marshes, as well as patches of tropical seasonal forest, coastal dunes and palm trees.
Eleven major rivers and their tributaries enter this ecosystem forming coastal lagoons where freshwater is mixed with sea water and the main activity is shrimp fishing. Biological diversity and richness of the site is extraordinary and includes a number of wildlife species such as Jaguars, river crocodiles and alligators, spider monkeys, and more than three hundred species of birds one hundred of which are migratory.
Approximately 29,300 people live in the biosphere reserve and are mainly engaged in four economic activities: fishing, agriculture, stockbreeding, and tourism.
  Major ecosystem type   The reserve is characterized by a large area covered by mangroves, in addition to patches of deciduous seasonal forest and lowland deciduous forest, as well as plant associations such as tulares Popal, zapotonales, floating and underwater vegetation, palm trees and coastal dunes vegetation.
  Major habitats & land cover types   31,243 ha of mangroves, 31,443 ha of popales y tulares, 741 ha coastal dunes vegetation, 16,224 de sabana costera, 7,177 ha of water bodies. The marine area extends over 29,214 ha and agricultural and stockbreeding area cover 28,816 ha.

  Brief description   A strategy aiming at institutional synergy for the management of research is implemented in this site, with the intention of facilitating the development of prioritized research in basic and applied sciences, with participation of research centres, universities and local, regional and international experts. A monitoring for monitoring of natural resources is also developed generating information about groups and / or species for conservation such as jaguars (Panthera onca), American crocodile (Crocodylus acutus) and spider monkey (Attel geofroyii). A programme for monitoring the quantity and quality of water is also carried out.
