Four Canadian wolves were recently transported by helicopter from Ontario to Michigan’s Isle Royale National Park. The wolves were relocated to help deal with the moose population on the island, and to restore the dwindling number of wolves that currently live on the island. In the past, ice bridges have connected Isle Royale to the mainland, allowing wolves to migrate. Over the last twenty years, however, these ice bridges have become inconsistent, stranding wolves on the island and preventing any newcomers. The four new wolves will join two that were relocated to the island in 2018. Over the next five years the National Park Service hopes to introduce 20 to 30 wolves to the park.
