They need old growth forests for survival
My wife and I were fortunate enough to see a fisher as we were driving over Lolo Pass a couple of years ago. This is one of the few areas where fishers still have a native population in the Rockies and, according to the press release, they are genetically distinct from other populations. There have been several attempts at re-establishing them to other areas with limited success.
The decision to move forward is a result of a petition rather than a lawsuit.
