These are not my numbers, these are the numbers from the international wolf center. I'm sure they would be the first ones to admit that the numbers are not exact, but good estimations. Northern Minnesota is very sparsely populated especially the northeast, and it is not that small, It would be about 35,000 Square Miles of wolf territory, with each packs territory being between 25-150 Square miles.I promise you there is plenty of ungulates and other game for the wolves to eat. Skepticism is good, so your best bet would be to contact the Wolf Center in Ely, and ask them how they come up with those numbers.
