Soil and Terrain

The general forms of the landscape were shaped mainly by the action of the glaciers about 11,000 years ago. When the ice retreated formed drainage systems, forming numerous lakes, streams and rivers have rapids and waterfalls. Then the area was covered by volcanic ash, which helped to develop fertile soils.

The region is bounded by mountain ranges.


Trevelin is located in the humid zone of Patagonia, but almost at the edge of the dry zone, so the landscape ranges from grasslands and prairies in the east, a transitional park which overlooks the tree called maitén and west, almost in the foothills of the Andes, cold forests of raulíes, beech, evergreen beech, ñires, Patagonian cypress, radales, maquis, myrtles and giant lahuanes or larch (Fitzroya cupressoides), reaching 60 meters high, 3.5 meters in diameter , aged over 3,000 years. Under these tree species are abundant in the understory which include strawberry, sarsaparilla, caulk and mushrooms among others.

Within the National Park Alerces we find annual rainfall of 4,000 millimeters of forming an Andean-Patagonian forests rich in vegetation: the forest Valdivia, where the larch stands, one of the largest trees plañera longevity. This national park is created to give protection to these forests of larch, which at the beginning of the twentieth century was about to disappear by the uncontrolled exploitation of man. On the sides of these majestic specimens Menéndez lake have an estimated age of 4,000 years and 70 meters high.

The musk rose, lupine and daisies are exotic European became a serious problem of conservation of native species due to its high dispersion without help, displacing the original ones.

Trevelin is an exceptional microclimate, and in protected areas such as Lake Baguilt we can find the lichen group associating plant fungi and blue-green algae or green, their presence is synonymous with "clean air", since it only develops in uncontaminated sites.


Are many species of birds like the chucao, the black carpenter Patagonia, pitta, the Caburé, parrot southern Patagonian thrush, the dove araucana (endangered) lapwings, ducks, ibises, flamingos, rheas, gulls, hawks, owls, and so majestic birds such as condors and other species.

The National Park is home to many Alerces endangered species like the Pudu (species of deer or deer), the cat huiña, or otter huillín Patagonian tuco-tucus the (a burrowing rodents living in caves), the puma and most important of all, the huemul, a native deer species that inhabits the Patagonia Patagonian forests, is in grave danger of extinction. In Argentina, huemul has been declared National Monument, maximum protection that can be given to a species. This deer can be seen on the hill to Riscoso declared a critical area for conservation of the species. If they see a huemul in any sector of the park (an almost impossible dream), it is important to report to National Parks, to keep it safe and keep your changes.

Poaching threatens both huemul as the puma, both copies prized by poachers. On the other hand introduced species such as red deer, the deer lady, wild boar, mink and hares, have serious repercussions.

In its many lakes, rivers and streams are abundant salmon and trout species as prized by anglers.

It is very common in the viewing area on the road or in any walk of guanacos (a kind fun and curious). In the cabins every now and see: lapwings, ibises and hares, the latter is the currency especially in the late afternoon or night falls. In the park you can see the chucao calmly, since this bird is very tame and curious.
