Ripple, a professor in the university’s College of Forestry and an author of the study, said aspens were recovering in areas where it would be difficult for elk to escape a wolf attack. “We think these elk need to balance the risk of being killed versus eating in their favorite places. So it’s a trade-off between food and risk in an ecology of fear,” he said.
