How Wolves Help

In the short time since wolves were reintroduced to the American West in 1995, scientific research has revealed that they have restored stability ecosystems.  Because of this role, wolves are designated a “keystone species” and often referred to as “ecosystem managers.” Wolves….

Strengthen ungulates – Wolves cull sick, old and genetically inferior elk and deer, allowing the healthiest individuals to breed and perpetuate their species. Wolves are the only predator in North America that do this.

Feed other animals – The remains of a carcass left behind, unfinished by wolves, help feed grizzly bears, bald eagles, wolverines and many other scavengers.

Improve riparian areas – Wolves have redistributed the elk herds, allowing vegetation to recover along rivers and streams. More willows and aspens provide food for beavers. More beaver ponds benefit aquatic plants and animals. Shade from the trees cools the water, making the habitat better for trout.

Decrease coyote populations – Wolves kill coyotes, so rodent populations increase, benefiting struggling birds of prey. Also, with fewer coyotes, pronghorn antelope calves are less likely to be preyed upon.

Boost to ecotourism – The reintroduction of wolves to Yellowstone has attracted 150,000 new visitors each year, adding $35-million to the local economy annually.
