Huilo – Huilo is part of a unique and little explored ecosystem, which corresponds to the jungle territory of Patagonia, in the southern Andes. In this territory areas of scientific and conservation interest are superimposed at world level. The Valdivian Ecoregion, also called Selva Valdiviana, is one of them and constitutes a narrow strip of forest that extends towards the south through approximately 1,600 km, from 35º to 47º south latitude. It is one of the 25 most valuable and threatened ecoregions on the planet. Considered a world “hotspot” in terms of biodiversity, its biological importance lies in its high levels of endemic species, variety of habitats and exceptional and unique plant formations.
