From Minnesota Public Radio:
Wolf populations are generally linked to whitetail deer. There are a lot of deer right now, which means a lot of food for wolves. That in turn means more packs, and more pups living to maturity.
There are now approximately 500 packs, and more than 2,800 wolves across the northern half of the state, according to a Minnesota DNR survey released this week. That’s almost 600 more wolves than last year.
