Park Service Weighs Whether to Boost Dwindling Isle Royale Wolf Numbers

In the late 1940s, Isle Royale’s moose population, which swam to the island decades earlier, welcomed some new visitors: a group of gray wolves. The wolves had walked to the Michigan island from Canada, crossing Lake Superior in the winter when the water was frozen and establishing Isle Royale as their new home. The wolf population grew over the next several years, preying on moose and mating both internally and with new wolves who crossed the ice bridge during the winter. Now the wolf population is in trouble…Repopulate the island’s dwindling wolf population, or allow the species to go extinct on the isolated island?
