Scientists: Pup Births Hopeful Sign for Isle Royale Wolves

Isle Royale National Park

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, Michigan’s Upper Peninsula and the Canadian province of Ontario to the Lake Superior park several years ago.

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.
