YASUNI

 
       
  General Description   The Yasuni Biosphere Reserve and National Park is situated in the Amazonian region, in Napo Province in the north of the country. The terrain is very sinuous, despite of being in the Amazonian plains. With the exception of Rio Napo, which originates in the foothills of the Andean Cordillera, rivers crossing the national park originate at altitudes from 300 meters to 600 meters above sea level. The topography is represented by low plains alternating with the foothills of the Andean chain, with a softly inclined platform supported by the Guyano-Brasilian shield that extends from the south of Colombia to Peru. Three main types of vegetation occur: 'Terra firme', found on the high reliefs areas and not subject to flooding; 'Varzea', a forest type subject to periodic flooding, and 'Irapo' in the permanent or near permanent flooded forest. Cononaco is traditionally a settlement area for indigenous communities such as the Huaorani, Aucas and Quichuas. There are more than 9,800 people engaged in agriculture (coffee, bananas, yuca, paw paw, citrus fruit, maize and achiote), fishing, forest dwelling, hunting and gathering forest products. About 150 people visit the reserve each year; the potential for tourism is considerable and therefore encouraged. Oil exploitation by the National Petroleum Company affects local communities’ social practices and the natural ecosystem. The objectives of the biosphere reserve are to conserve natural ecosystems, to provide protective legislation, in situ conservation, encourage regional planning and rural development, encourage local participation in land use and environmental education
