On Isle Royale, Park Service intervenes to save nature – StarTribune.com

The National Park Service has proposed transplanting up to 30 wolves to Isle Royale, a historic decision that concedes that extraordinary steps are needed to restore a healthy balance of predator and prey on the wilderness island in Lake Superior.After years of deliberations, the Park Service has concluded in a new report that quickly introducing a significant number of wolves may be the best way to re-establish a healthy population on the island. Only two wolves are left there now — down from a one-time high of 50 — a result of disease, inbreeding and a warming climate that has reduced the frequency of ice bridges that give them a natural route to and from the mainland.
