      Biosphere Reserve Information



  General Description   The Laguna de Pozuelos Biosphere Reserve is located in the high Andean region of Argentina in the Jujuy Province. The ‘Laguna de Pozuelos’ is one of the best examples of an inland drainage basin with saline, intermittent lakes and a few permanent lakes. This basin is the most humid in the Argentine ‘Altiplano’, due to the relatively high rainfall and also to the presence of an important aquifer. The vegetation is characterized by ‘tolilla’ (Fabiana densa) and ‘chijua’ (Baccharis boliviensis) shrubs. The wet areas around the watercourses in the upper parts of many streams are covered by permanent green meadows, called ‘Vegas’ and the lower parts of the streams consist of grasslands and marshlands (‘Cienagos’) used for pastoralism. The only tree existing in the area is the ‘Queñoa’ (Polylepsis tormentella spp.) used for firewood and as construction material. The most important birds in the area are flamingos (Phoenicoparrus jamesi, P. andinus), and one of the main animal resources in the area is the vicuna (Vicugna vicugna). Over 3,800 inhabitants (1990) live in the biosphere reserve engaged in intensive pastoralism, mining, and exploitation of firewood. The main goal of the Biosphere Reserve is to restore degraded lands, develop ecotourism and reforestation with ‘queñoa’. In the ‘Laguna de Pozuelos’, an attempt has been made at making socio-economic development compatible with conservation, promoting the participation of local populations in decision making processes, planning a series of actions aimed at improving animal husbandry practices, sustainable construction technologies and introducing new methods of natural resource use.
