Chile

LAUCA

 
       
  General Description   The Lauca Biosphere Reserve is situated in the Puna biogeographic region, in the northern part of Chile in the Andean Chain. The area comprises three protected areas: Lauca National Park, ‘Las Vicuñas’ National Reserve and ‘Salar de Surire’ Natural Monument. The Biosphere Reserve has high floristic value, representing a large part of Andean biodiversity in Chile. The vast plateau of the Altiplano consists of meadows, crossed by deep gorges, dotted with lagoons, dark lava outcrops and occasional white sparkling saltpans, with a number of permanent fresh, brackish and saline lakes, marshes, as well as fast flowing mountain rivers and streams. There are three principal plant formations: tolar, Andean steppe, and llaretal. Tolar is characterized by shrubs with the tree Polylepis tarapacana and the cacti Opuntia spp. The Andean steppe comprises perennial Andean grasslands and wet meadows as well as grass species. The llaretal is characterized by Laretia spp. with cushion-like specimens. Although not very abundant, the fauna is diverse. Mammals include lama (Lama glama), alpaca (Lama pacos) and vicuña (Vigugna vicugna). Noteworthy birds are puna ibis (Plegadis ridgwayi), huallata (Chloephaga melanoptera) and Andean condor (Vultur gryphus). Only 200 elderly people (2000) of the Aymara tribe are living in the area in a traditional fashion with sustainable use of the natural resources . In 1997, around 30,000 national and 9,000 international tourists visited the reserve. There is some income generation for local population, mainly from handicrafts and guiding of tourists.
