USFWS is reviewing the status of the fisher to determine whether it should be added to the Endangered Species List . . .
The U.S. Fish and Wildlife Service announced Friday the initiation of a status review for the distinct population segment of Northern Rocky Mountain fisher, to determine whether this population meets the definition of an endangered or threatened species under the Endangered Species Act.
Bigger than a marten, but smaller than a wolverine, the fisher is in the same family that also includes weasels, mink, and otters. Fishers live in coniferous and mixed conifer and hardwood forests and are found commonly in mature forest cover. They’re one of the few creatures that kill and eat porcupines.
In Montana, the best fisher habitat is in the old growth wilderness of the Selway-Bitterroot. While fisher tracks have been noted in places like Glacier National Park, extensive hair trapping studies done a few years ago did not find any fishers, according to Park biologist John Waller.
