The wolf population in Michigan is now being controlled by the state. In Minnesota, officials are considering a hunting season.

Michigan Radio’s Rebecca Williams visited Isle Royale, a remote island in Lake Superior reachable only by ferry or airplane.

Williams spoke with scientist Rolf Peterson about the island’s diminishing wolf population.

“Over the past 54 years, researchers have collected more than 4,000 moose skeletons on the island.  The bones offer clues about the moose population – and about the wolves.  Wolves got here by crossing an ice bridge from Ontario in the late 1940’s,” said Williams.

Peterson’s studies are extensive.

“This study of wolves and moose is the longest running study in the world of a predator and its prey.  Rolf Peterson has been involved for 42 years of the study. He’s been here through the brutal black fly summers and the harshest winters. He and his wife Candy live in an old fishing cabin on the island for much of the year,” said Williams.
