Te Wolf Reintroduction Success Sory

By the 1920s, wolves were eradicated from Yellowstone due te predacor control kampanins andd habitat loss. Their absence result in elk overpopulation, leading to overbrowsing of woods plants andd degradation of riparian ecosystems. In 1995, a landmark reconsultation initiative brought 31 gray wolves frem Canada back into Yellowstone, initing a profound ecological transformation.
