      Biosphere Reserve Information



  General Description   Araucarias Biosphere Reserve is situated in the southern part of the volcanic Andean chain, in south-central Chile. The biosphere reserve includes two national parks: ‘Conguillío-Los Paraguas’ which constitute the core area, and the ‘Alto Bio-Bio’ forest reserve constituting the buffer zone. The Conguillío is characterised by forests of Nothofagus with Araucaria (A. araucana) forests, rivers and lakes. The Alto Bío-Bío has Andean steppe with pasture lands and agroecosystems. The most prominent species of the biosphere reserve is the Araucaria, also called ‘Monkey Puzzle’ or Chilean Pine, which has been declared a natural monument in Chile. Four species of Nothofagus are encountered, as well as Podocarpus andinus and Austrocedrus chilensis. Among the mammal species, the ’pudu’ (Pudu pudu) and ‘guanaco’ (Lama guanicoe) are particularly noteworthy. The very rare marsupial Dromiciops australis occurs within the biosphere reserve, and both the avifauna and herpetofauna are very rich. Areas which have been grazed in the past or subject to forest exploitation are all set-aside as ecosystem restoration zones. The Alto Bio-Bio Forest Reserve (buffer zone) has a population of about 20 families (1980) engaged in pastoralism. Around 25,000 national and 1,700 international tourists annually visit the core area. The biosphere reserve offers a great potential for scientific research and studies have been undertaken, particularly on the reintroduction of the guanaco (Lama guanicoe). Some environmental education activities also take place.
