Wolf after re-introduction. The history of wolves in Yellowstone includes the extirpation, absence and reintroduction of wild populations of the gray wolf (Canis lupus) to Yellowstone National Park and the Greater Yellowstone Ecosystem. When the park was created in 1872, wolf populations were already in decline in Montana, Wyoming and Idaho.
Map showing wolf packs in the Greater Yellowstone Ecosystem as of 2002. Grey wolf packs were reintroduced to Yellowstone National Park and Idaho starting in 1995. These wolves were considered as “experimental, nonessential” populations per article 10(j) of the Endangered Species Act (ESA). Such classification gave government officials ...
Greater Yellowstone Area Wolf Pack Territories 2002 (95% MCP except where noted) * A 75% MCP was calculated for these five home ranges because of a high fluctuation in movements.
The Greater Yellowstone Ecosystem (GYE) is one of the last remaining large, nearly intact ecosystems in the northern temperate zone of the Earth. [1] It is located within the northern Rocky Mountains , in areas of northwestern Wyoming , southwestern Montana , and eastern Idaho , and is about 22 million acres (89,000 km 2 ). [ 2 ]
When considering the issue of wolf reintroduction in 2016, the commission adopted a formal resolution opposing intentional release of wolves. [18] Six gray wolves were photographed or killed in Colorado between 2004 and 2019. [19] These animals are most likely from the natural dispersion of those reintroduced to Yellowstone National Park.

William Ripple is the author of more than 100 peer-reviewed scientific articles, most of which deal with trophic cascades. [10]Ripple, along with his frequent coauthor, Robert Beschta, have studied, published, and publicized the positive impact that gray wolves have had on the Yellowstone National Park ecosystem since their reintroduction in 1995 and 1996. [11]
A classic example of a terrestrial trophic cascade is the reintroduction of gray wolves (Canis lupus) to Yellowstone National Park, which reduced the number, and changed the behavior, of elk (Cervus canadensis). This in turn released several plant species from grazing pressure and subsequently led to the transformation of riparian ecosystems. [17]
Yellowstone National Park forms part of the boundary to the west; south of Yellowstone, the Continental Divide separates the forest from its neighbor Bridger-Teton National Forest to the west. The eastern boundary includes privately owned property, lands managed by the U.S. Bureau of Land Management and the Wind River Indian Reservation , which ...
