      Biosphere Reserve Information



  General Description   The Laguna Blanca Biosphere Reserve is a typical treeless Patagonian steppe with crystalline rocks, including some sedimentary rocks with fossils of the genera Ostrea and Trigonia. The Biosphere Reserve contains the Laguna Blanca a saline lake in a main depression, at 1,267 metres above sea level, surrounded by some forest and mountains culminating at over 5,000 m. This area is of particular interest for its birds, and was in fact established to protect the black-necked swan (Cygnus melanocoryphus) which is found here in great abundance Geese found on the lake include the upland goose (Chloephaga picta), shovelor (Anas platalea), and blue-billed duck (Oxyura australis). Mammals include the opossum (Marmosa pallidior) and the skunk (Conepatus suffocans enuchus). The 600 inhabitants living in the transition area (1986) are engaged in traditional practices including livestock raising (sheep, goats, mules and cattle). Training courses aiming on improving rural development, cultural events, research and monitoring also take place. Some 2,500 tourists visit the Biosphere Reserve each year for ecotourism and environmental education.
