The story on howlboxes had the latest map [link now dead] of the location of Montana wolf packs.
The Montana wolf population has been improving rapidly (my view) the last several years, with lots of areas with gaps filling in, but Idaho plans to decimate the wolf population in the upper Clearwater River area along the Idaho/Montana border could have a large effect on Montana wolf packs because many of the packs cross back and forth over the state line or are derived from Idaho wolf packs. Given a big wolf reduction effort in Idaho’s upper Clearwater, the Montana wolves would continually migrate back into the killing zone in Idaho.
