Index of Subjects The current status of this beaverblitz was featured on a TV program aired some months ago (maybe on PBS or the Suzuki show, I forget, but perhaps someone else on NNS saw it). This program showed seriously drowned forests caused by all the dams made by the beavers and their logging efforts, and either the Chilean or Argentinian government was about to mount an eradication campaign. Tierra del Fuego is in fact a big island plus some smaller ones, and the huge concern was that beavers will eventually swim out of the big island across the fairly narrow Straits of Magellan and start to colonize the S. American mainland, then becoming even more difficult to control. It was news to me, but apparently beavers have been known to do this, swim for some distance in seawater, so the thought was that this was bound to occur sooner or later: control measures needed to be implemented quickly to prevent them spreading further north. I doubt that they yearn to come back "home" up here, though -- they are presumably quite happy colonizing away down there, where they've got no major predators, unlike in N. America.
