Wolf population in Isle Royale NP likely down to a single individual; moose numbers boom as result

Isle Royale may be down to a lone wolf, as the federal government ponders whether it will replenish the pack on the northern Michigan Island.

For the past two years, a male and female wolf have held on as the last remaining pair of wolves on the more than 200 square-mile island that's part of a national park in Lake Superior. The pair were spotted in the summer of 2016, on the motion-triggered trail camera of Michigan Technological University wolf researcher Rolf Peterson, and again in Michigan Tech's annual winter survey of the island last January.
