Hmm mm I personally would not go west to hunt..yes due to possible negative interactions with and by local indigenous individuals. .however there are numerous locations with healthy bear populations.
I have not ever heard of wolves digging bears out of their dens.
However I would not question local knowledge..
There are extensive areas of high density bear activity..far more bears than I would consider reasonable removable by winter wolves in one winter..last spring I am aware of 10 black bears harvested near Horsefly...3 of them in our group..and we let maNY live..other hunters separate from ours harvested numerous bears and saw many others..area was 25 kilometers in length.
Again I repeat I have not heard of wolves digging out black bears during Denning season..ever..BUT do not argue or dispite local knowledge..
