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 ...
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.

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.

A reintroduced wolf in Yellowstone National Park. Starting in 1914, to protect elk populations, the U.S. Congress appropriated funds to be used for "destroying wolves, prairie dogs, and other animals injurious to agriculture and animal husbandry" on public lands. Park Service hunters carried out these orders, and by 1926 they had killed 136 wolves.
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 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 ]
