HOUGHTON (AP) — Scientists say gray wolves relocated to Isle Royale National Park are adjusting nicely to their new surroundings and finding plenty of prey.

Officials released findings Monday from observations of wolves that were captured on the mainland and taken to the Lake Superior park during the past year.

Plans call for moving 20 to 30 wolves to Isle Royale to restore a population that had nearly disappeared because of inbreeding. The park’s current total is 17.

The radio-collared wolves were monitored over the summer by park staffers and researchers with the State University of New York.

They studied remains of animals the wolves had eaten and concluded that more than half of the prey were moose. But the wolves also feasted on beavers and snowshoe hares.
