      Biosphere Reserve Information



  General Description   Covering 1,392,900 ha Río San Juan Biosphere Reserve is composed of seven protected areas and other adjacent territories. The biosphere reserve covers an important variety of ecosystems representative of tropical humid forests and wetlands, tidal marsh, coastal lagoons and estuaries which are important shelters for rare or threatened animals and plant genetic resources of the meso-American tropics. Furthermore the biosphere reserve includes a part of Lake Cocibolca and the municipalities of El Almendro, San Miguelito, Morrito and Nueva Guinea with a large (256,000 habitants) and culturally rich human population including 20,000 habitants of Rama, Miskitu, Negra and Creole ethnic groups. Each one of these groups has its own way of preserving and/or using the national resources of the area.
The vast size of the biosphere reserve, in addition to its proximity to neighbouring Costa Rica protected areas, and as part of the Mesoamerican Biological Corridor, guarantee an adequate area for preserving genetic diversity, free mobility of species, breeding and maintenance of major species such as the jaguar or american tiger (Felis onca), the tapir (Tapirus biardii) and the red and green parrot (Psittacideae).
