HOUGHTON, MICH- The National Park Service will be relocating wolves from Ontario to Isle Royale this winter. Isle Royale and their partners successfully relocated 4 wolves from Minnesota to the park this fall in an effort to restore predator prey dynamics to the island ecosystem. The support and assistance of Michigan Governor Rick Snyder and Ontario Premier Doug Ford made the next step of the Isle Royale wolf translocation project possible.
“We greatly appreciate the efforts of Michigan Governor Rick Snyder to facilitate this project and thank Premier Ford and Minister Jeff Yurek for their decision to provide Ontario wolves,” said Isle Royale Superintendent, Phyllis Green. “We look forward to working with the professionals from the Ontario Ministry of Natural Resources and Forestry.”
Several wolves will be captured during the winter months and moved from Ontario to the isolated island park. The wolves from Ontario will play a critical role in restoring a robust wolf population at Isle Royale that functions as an apex predator.  “Ontario and Michigan have a long history of friendship and a proud tradition of working together to conserve our natural ecosystems”, said Ford. "We all have an important role to play in protecting the environment and we’re happy to do our part to help Michigan’s wildlife thrive.”

The winter effort is part of a three- to five-year plan to relocate 20 to 30 wolves to Isle Royale. 

Researchers recommended this number of wolves to establish adequate genetic variability to help accomplish the overall goal of restoring predation as a key part of the ecosystem on the island.  The NPS along with its partners, plans to monitor ecological conditions and other factors, such as predation rates, genetics, moose-wolf ratios, and terrestrial and aquatic vegetation impacts to evaluate project success. Along with the state of Michigan and the province of Ontario, the NPS is collaborating with the Grand Portage Band of Lake Superior Chippewa, Michigan Department of Natural Resources, Minnesota Department of Natural Resources, U.S. Fish & Wildlife Service, U.S. Department of Agriculture Wildlife Services, U.S. Geological Survey, University of Minnesota, and personnel from multiple NPS units. 
Photos, video clips, interviews, and updates will remain posted for the media on the Isle Royale National Park website,  Information and photos from the project will continue to be shared on Facebook Isle Royale National Park/, and Instagram, @isleroyalenps.
