The North American beaver (Castor canadensis) is an invasive species in Tierra del Fuego, at the southern end of Patagonia. Tierra del Fuego is a large island encompassing parts of Chile and Argentina, so that policies and actions to control the species have mainly been binational. The beavers were introduced to the area in 1946 in an effort by the Argentine government to establish a fur trade in the region.[2] Since then, the beavers have spread throughout most of Tierra del Fuego and have also been seen on the Brunswick Peninsula of mainland Chile.[3] When the fur trade failed to establish, the beavers became problematic and the two governments agreed to intervene to eradicate them.[4][5]
A June 2011 NPR report stated that the beavers have caused millions of dollars of damage.[6] According to Nature, it is the largest eradication project ever attempted.[7]
