In the 1970s, as gray wolf populations continued to dwindle, the U.S. government took protective action, listing the animals as endangered. In 1995 and 1996, the government reintroduced gray wolves in Idaho and Wyoming's Yellowstone National Park. From these locations, gray wolf populations expanded to northern California, Oregon, Montana, and Washington State. As of today, according to data from the U.S. Fish and Wildlife Service, the total gray wolf population stands at 6000.

However, environmentalists have strongly criticized the gray wolfs removal from the Endangered Species list. They view the decision as premature and potentially hurtful to wolves, who have not yet gained a strong foothold in many ecosystems.

Colorado, a former reserve for gray wolves, has narrowly passed a vote to reintroduce gray wolves in the state's forests and mountain ranges. Wolf supporters and conservationists connect the animals' benefits with the environment. Gray wolves help maintain healthy elk and deer populations and help limit overgrazing, which can lead to soil erosion. Wolf opponents, on the other hand, fear increased livestock deaths and greater risk to farmers and rangers in rural areas because hunting and livestock raising arc among the biggest careers in western states.
