Only 1 wolf now seen on Michigan’s Isle Royale

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 last two years, a male and female wolf have held on as the last remaining pair of wolves on the 893-square-mile island 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…The remaining pair were a father and daughter, and they were born from the same mother, making them half-siblings and highlighting the severe inbreeding that has decimated the island's wolf pack. Past offspring by the pair were small and unhealthy, and did not survive. Peterson said that while it's unclear from the trail cam shot, he believes the lone wolf viewed this summer is the female.
