Normally I'd say leave nature alone and let it take it's course, but since we've already messed with it, we need to try to manage it. It's unlikely we can reverse the way we have encroached on their territory. One of the problems with the wolves is the fact that they can find and run down wild life much easier today than they could even 20 years ago. Clearcut logging of not only regular forests but the more recent pine beetle logging of vast tracts of forests leave ungulates with less cover. Add to that logging roads and things like snowmobile trails in the winter, gives wolves a huge advantage. Of course the more successful they are in their hunts, the more they reproduce.
I question the numbers in the article that suggests that there are only 400 more wolves today than there were 20 years ago. It would be interesting to know what sort of surveys they took to come up with those numbers. If there were 8100 20 years ago, I would suggest there are at least double that number today...
