>Patagonia is going to have a lot of new "Canadian" residents in the next six months.
Fuck off we're full.
It seemed like a good idea at the time.
Transplanting 25 pairs of Canadian beavers to Tierra del Fuego would provide raw material for a fur industry, bring jobs to a sparsely populated region and — as an advertisement in 1946 suggested — possibly attract tourists to this remote part of the hemisphere by "enriching the local fauna."
Seventy years later, the placement of the nonnative, wood-chewing mammals in Fagnano Lake along the Chile-Argentina border is viewed as a colossal mistake. On the Chilean side of Tierra fel Fuego alone, the beaver population has swelled to about 200,000, and the giant, semiaquatic rodents can be found near the wind-swept city of Punta Arenas, some 200 miles northwest from the lake.
Probably with human help, they even have crossed the Magellan Strait to inhabit several islands.
The problem is that the beavers, being beavers, have built hundreds of dams, and though beaver dams can invigorate some ecosystems, in Patagonia they are creating harmful floods that threaten the primeval forest of lenga trees and nearby lakes.
