Las Yungas Biosphere Reserve, located in northwestern Argentina's mountainous Andean Range, encompasses a rich diversity of landscapes from the high Andean mountain forest ecosystems to Chaco Serrano, cloud forests, montane forests, grasslands and agricultural land.
Las Yungas Biosphere Reserve is located in northwestern Argentina, within the southernmost part of the eastern mountainous forest of the Andean Range. It is situated within the Argentine provinces of Salta and Jujuy.
The Biosphere Reserve encompasses a rich diversity of landscapes from the high Andean mountain forest ecosystems, Chaco Serrano, cloud forests, subtropical low mountain jungle, montane forests, and grasslands; as well as 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 in 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.
Las Yungas Biosphere Reserve expresses the mixed historic, social and cultural practices in highlands and lowlands of the region.
