HOUGHTON, Mich. – The Isle Royale fall wolf translocation project concluded on September 13 after successfully moving three wolves from Michigan’s Upper Peninsula to the park. The new wolves, two males and one female, bolstered the total island wolf population to 17, which now includes nine males and eight females. A fourth wolf was moved to the park on September 13, but its collar sent out a mortality signal over the weekend. Biologists from the National Park Service (NPS) and State University of New York – College of Environmental Sciences and Forestry (SUNY-ESF) located the wolf and confirmed the mortality late on Tuesday afternoon. The carcass of the wolf will be sent to the USGS National Wildlife Health Center in Madison, Wisconsin, for necropsy. The three to five year effort to establish 20 -30 wolves on Isle Royale is being completed in order to restore predation as a key part of the island ecosystem. Researchers involved in the planning effort recommended this number of wolves from the Great Lakes region. Additionally, they recommended an equal number of males and females in order to establish genetic variability in the new population. The NPS and its partners will monitor the wolf population to determine evidence of social organization, reproduction and predation.
