Evergreen and Deciduous temperate forest, perennial grass in Oromo Exp. See point of contact above The site is located in a cold temperate climate in the middle of the unique North Patagonian rainforest, subantarctic rainforest and the Valdivian temperate forest unique in the southern hemisphere.
Winters are relatively mild and the annual temperature range is small.
The pattern of rainfall in the region is a function of orographic lifting of air masses moving in from the polar Pacific front. This produces heavy rains in the coastal mountains, a diminished amount in the central valley and increasing amounts at progressively higher elevations in the Andes Mountains. These elements are of considerable importance for the terrestrial and lacustrian biota. The presence of large lakes created by glacial moraines, small lakes occupying cirque basins, perpetually snow-covered volcanic peaks, glaciated valleys and dense temperate rain forests create a natural laboratory for ecological diversity. Many ecological studies including flora, fauna and geology have been carried out at the site.
