The PGC or the Forest Service release fishers or pine martins [the same I beleive]a few years ago in the Allegeny National Forest. Reasons behind this was to cut down on the porcupine population. The locations of the release was in the Minster Creek and Tionesta Creek area. Seen two last year in Forest Co. and they were about three foot long and about ten or twenty pounds. Didn't feel like picking it up to see how big its' teeth was. Look like a big long house cat.
