South America’s southernmost ecosystems are highly disturbed by the presence of beavers, Castor canadensis, an exotic rodent that was introduced into the archipelago in 1946. Today, this species has reached South America’s mainland, threatening the survival of natural and productive ecosystems in southernmost South America.

WCS, jointly with relevant Chilean, Argentinean, regional, national, and even international actors is developing a Program for the restoration of Patagonian ecosystems to their condition prior to the release of the American beaver. To this effect, the beaver must be eradicated from its current artificial distribution range in the southernmost tip of South America, and the environments affected by this exotic species recovered or restored.
