Gray wolves (Canis lupus) translocated to Isle Royale National Park in Michigan are forming social groups and territories and mating. And they’re succeeding in reducing the park’s moose (Alces alces) herd, which was why the wolves were brought to the island.
“They’re having no trouble finding and preying on moose, and that’s really significant,” wildlife ecologist Rolf Peterson told the Associated Press. “The signs are all positive, I think.”
Biologists believe the wolf population is at least 12, including at least two wolf pups spotted on trail cameras. Plans call for 20 to 30 wolves to be taken to Isle Royale over three to five years.
