How did the reintroduction of wolves affect the rivers in Yellowstone?
Remarkably, the presence of wolves also changed the rivers. Riverbank erosion decreased so the rivers meandered less, the channels deepened and small pools formed. The recovering vegetation stabilised the riverbanks, which in turn changed the geography and microclimate in the park.
What would happen if wolves were removed from Yellowstone?
Removing wolves from the park affected much of Yellowstone because wolves are top predators and arguably keystone species. Wolves feed on elk, and without the wolves, the elk population exploded. The elk fed on young aspen trees, so the park had very few young aspen trees.
What happened to Yellowstone after the wolves were killed?
Ecological impacts Once the wolves were gone, elk populations began to rise. Over the next few years conditions of Yellowstone National Park declined drastically.
