Scientists: Pup births hopeful sign for Isle Royale wolves

Michigan Technological University

TRAVERSE CITY, MI (AP)--   Scientists say wolf pups have been spotted again at Isle Royale National Park, and that's a hopeful sign for efforts to rebuild a gray wolf population that had nearly died out.

Crews brought wolves from Minnesota, the Upper Peninsula and the Canadian province of Ontario to the Lake Superior park over the past few years. It's unknown how many are there now because the coronavirus pandemic forced cancelation of the annual winter census. But researchers with Michigan Technological University say remote cameras have detected a number of pups.

Meanwhile, the park's overgrown moose population appears to be dropping.
