Reintroduction of Wolves to Isle Royale Shows Fleeting Impact on Wildlife
From Nature World News:
In 2019, 19 wolves were reintroduced into Isle Royale National Park with a view to returning its ecosystem to its natural balance. Climate change made it impossible to bridge ice bridges between the island and the mainland, causing the population of wolves on the island to drop, leaving only two inbred individuals, which made this effort necessary.
The study, which was just published in Frontiers in Ecology and the Environment, used DNA analysis from fox and marten scat and hair to evaluate the effects of the wolves’ return.
