As part of their proposal to âreintroduceâ 750 Mexican wolves, these scientists want to have a self-sustaining population of 250 wolves in southern Utah and northern Arizona â places that fall well outside the predatorsâ historic range.
They still roam these areas, but in much reduced ranges and numbers. Today, about 3,000 wolves live in the wild in Minnesota, around thirty on Lake Superiorâs Isle Royale, about 500 in Michiganâs Upper Peninsula, 500 in Wisconsin, and about 1500 in the northern Rocky Mountains of Montana, Idaho and Wyoming. An occasional wolf is seen in Washington state, and in North or South Dakota.
