Black-footed Ferrets Coming Back from the Brink

In 1981 the black-footed ferret, was “rediscovered” on grasslands inWyoming. Until then, biologists thought the last known individual had died in captivity in 1979. Today the nation’s rarest land mammal species is back in the wild, thanks in part to the major advocacy campaign that Defenders launched in the mid-1980s, when only 18 of these creatures remained.  We pushed hard to speed up the listing of imperiled species and to develop sound recovery plans for those already listed—like the black-footed ferret.

After years of successful captive breeding, the species was reintroduced in Shirley Basin, Wyoming, in 1991. Today there are more than 700 black-footed ferrets living in 10 locations across the Great Plains. Their return the prairie is a stunning accomplishment— but one that we must be ever-vigilant to protect as private interest groups and opponents of wildlife conservation threaten to unravel the ferrets’—and Defenders’— hard-won gains.
