Public concerns over large losses of wild ungulates to predators arise when restoring large carnivore species to former locations or population densities. During the 1990s, mountain lion and grizzly bear numbers increased in Jackson Hole, Wyoming, and gray wolves were reintroduced to the Greater Yellowstone Ecosystem. We investigated effects of these predators, as well as black bears and coyotes, on mortality of an abundant and increasing prey species, elk.
