Relocated island wolves outlasting mainland wolves in new Isle Royale home
From sciencemag.org
Island life isn’t for everyone, nor, it seems, for every wolf.
One year into a federal effort to restock the wolf population in Isle Royale National Park in Michigan’s Lake Superior, a pack of eight relocated from a nearby island appears to be thriving, while four of 11 wolves brought from the mainland have died. Another wolf voluntarily departed last winter, returning to Minnesota over an ice bridge.
