      Biosphere Reserve Information



  General Description   The San Guillermo Biosphere Reserve in the northwest of San Juan province represents the mixed mountain and highland systems in the foothills and mountains of the Andes occupying the west sector of Catamarca, La Rioja, San Juan and Mendoza Provinces. The Biosphere Reserve constitutes two phytogeographical regions: the Chaco and the Andean region. The Chaco is a humid and swampy region extending from Bolivia and Paraguay to northern Argentina. The Andean region consists of steep and rugged highlands with river valleys and lakes, which support migrating species as the Andean flamingo and mammals as vicuna (Vicugna vicugna) and guanaco (Lama guanicoe). The Biosphere Reserve contains grasslands with or without shrubs and sub-desertic open matorral with valleys and steep slopes. It also comprises important archaeological sites and ancient indigenous villages in the Cerro las Tórtolas (6,323 metres above sea level), Cerro las Flechas (5,350 metres) and Cerro del Toro, an ancient ceremonial monument. Only 300 people (1999) live in the Biosphere Reserve temporarily, engaged mainly in mining activities, some cattle raising and hunting. A management plan is being elaborated with local authorities and local communities.
