摘要

It's enough to make conservationists howl. The existence, or not, of the eastern wolf as a distinct species has become a battleground in the fight to restore the iconic grey wolf to greater swathes of the US, What was an obscure taxonomic debate has become a major row, as the US Fish and Wildlife Service (FWS) tries to justify plans to remove endangered species status from the grey wolf. Wolves once roamed most of the US, but were nearly eradicated last century by hunters, Today there are about 5000 grey wolves in the contiguous US, almost all in the northern Rocky mountains and western Great Lakes regions - thanks chiefly to the protection afforded by its status. While those populations are recovering, and have already lost endangered status, the FWS proposal would hit hopes of further expansion.
