The wolf population in Yellowstone National Park was essentially wiped out by the mid 1920's. That changed in 1995, when the National Park Service reintroduced them there. So, 20 years later, how has the park's ecosystem responded to the return of the wolves? Watch how #NSFfunded Utah State University wildlife ecologist Dan MacNulty and his team work in partnership with the National Park Service to find out! Fuller understanding of what's happening in Yellowstone could translate to better predat

The story of wolves in Yellowstone is a remarkable tale of reintroduction and ecosystem recovery. In the mid-1900s, wolves were eradicated from Yellowstone National Park due to hunting and habitat loss. Without wolves, the park’s ecosystem suffered, with elk populations growing unchecked, leading to overgrazing and damage to plant life. In 1995, wolves were reintroduced to Yellowstone, and their presence triggered a phenomenon known as a “trophic cascade.” With wolves hunting elk, the elk popula
