  General Description   The Biosphere Reserve is located in the southernmost part of the eastern mountainous forest of the Andean Chain in the Provinces of Salta and Jujuy. It encompasses a rich diversity of landscapes from the high Andean ecosystems with mountain forest, ‘Chaco Serrano’, cloud forests to subtropical low mountain jungle, with montane forests, grasslands and agricultural land with sugar cane, citrus fruits, soya bean and cotton among others. Some 203 bird species are represented in the biosphere reserve such as the eagle (Spizaetus ornatus), ‘la pava del monte’ (Penelope dabbenei), and the military macaw (Ara militaris).Among the 89 species of mammal species reported in the reserve, ‘jaguar (Pantera onca), tapir (Tapirus terrestris), and ocelot (Leopardus pardalis) are found. Over 33,700 inhabitants (2002), mostly farmers descendants from the ‘Kollas’ culture, live in the biosphere reserve. Some of them as the ‘San Andres’ and ‘Finca Santiago’ communities have developed traditional subsistence agriculture activities, handicrafts, hunting, and timber extraction. Others are working in extensive sugar cane farms and fruits industries.The Yungas Biosphere Reserve expresses the mixed historic, social and cultural practices in highlands and lowlands of the region. The Strategic Plan (in preparation) will engage the local population participation in decision-making processes related to conservation and sustainable forestry activities and local development.
