The Future of the Wolves of Isle Royale

Isle Royale National Park is a remote island in Lake Superior where, between 2009 and 2018, the wolf population fell from 24 to only two - the lowest in more than 50 years. Now, the National Park Service is re-introducing wolves to the area in an effort to restore the role of these predators in the island ecosystem.
