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.
Wolf #10, a male, in the Rose Creek acclimation pen, Yellowstone National Park. Wolf reintroduction involves the reintroduction of a portion of grey wolves in areas where native wolves have been extirpated. More than 30 subspecies of Canis lupus have been recognized, and grey wolves, as colloquially understood, comprise nondomestic/feral ...
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.

With the reintroduction of gray wolves (Canis lupus) to Yellowstone National Park, much interest has been shown regarding the effects of a restored wolf population on both grizzly bears and black bears. Grizzly bears, black bears, and gray wolves have historically coexisted in much of the same range throughout a large portion of North America.
The ecosystem supports the largest free-roaming herds of American bison (Bison bison) on public land, [6] a species central to the region's ecological balance. Grizzly bears (Ursus arctos horribilis) and gray wolves (Canis lupus) are apex predators [ 7 ] that play crucial roles in regulating prey populations.
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.

But, for ...
In late 2008, Wolf 302M decided to disperse from the pack with a group of five younger males (his nephews and sons), drifting through rival pack territories until joining four females of the Agate Creek Pack, one adult, one young adult, and two yearlings, to form the Blacktail Plateau pack in late 2008, which 302M began leading.
