Question

How did the disappearance of the wolves in yellowstone national park affect other species living in the area?.

Answer 1

Even though Yellowstone elk were still preyed upon by black and grizzly bears, cougars and, to a lesser extent, coyotes, the absence of wolves took a huge amount of predatory pressure off the elk, said Smith. As a result, elk populations did very well-perhaps too well.
