The Range of the Gray Wolf

1630 CE - 2022 CE

Once the world’s most widely distributed land mammal, the gray wolf was systematically eradicated from the continental United States in the 20th century. Listed for protection in 1973 under the Endangered Species Act, the gray wolf was reintroduced in the American west, and made a limited recovery. In Yellowstone National Park the return of wolves reduced overgrazing from elk, which led to streambed regeneration of willow and aspen, and reduced the population of coyotes which led to increased pronghorn and red fox. In 2009, hunting gray wolves was legalized in Idaho and Montana, to reduce attacks on livestock, but had little effect. Many ranchers continue to lobby for the removal of the gray wolf’s status as an endangered species, despite regaining less than 1-3% of their historic population. Scientists advocate for ongoing protections and reintroductions, for the long-term viability of the wolves, as well as their cascading effects of ecosystem rejuvenation.

WHAT YOU CAN DO

  • Use non-lethal methods to protect livestock from wolves, such as guard animals, fencing, and range riders.

  • Support gray wolf recovery and reintroduction programs, which help restore balance to ecosystems by controlling overpopulated prey and benefiting species like beavers, elk, and willows.

  • Advocate for science-based wolf management policies and support organizations working to ensure wolves are protected under environmental laws.
