HOUGHTON, MICH– The National Park Service (NPS) has been monitoring the wolves that were captured in Minnesota earlier this fall and transported to Isle Royale as part of a multi-year project to restore predation in the remote park. Sixteen different wolves were captured on the Grand Portage Chippewa reservation. Seven of those wolves were collared and released either on Isle Royale or at the site of capture. Young wolves were ear tagged and released. Collaring and ear tagging contribute to the Grand Portage Band’s monitoring program. Ear tags have been invaluable in determining age of wolves for the Isle Royale project and in population estimates on the mainland.
