Yellowstone National Park recently published the latest Wolf Project Annual Report for 2014 on their website.
The number of wolves in the park increased by 9 over the prior year, when 95 wolves were counted in 2013. Wolf numbers reached their highest count within the park in 2003, when roughly 175 wolves were identified.
Although wolf packs once roamed from the Arctic tundra to Mexico, loss of habitat and extermination programs led to their demise throughout most of the United States by early in the 1900s. In 1973, the US Fish and Wildlife Service listed the northern Rocky Mountain wolf as an endangered species and designated Greater Yellowstone as one of three recovery areas. From 1995 to 1997, 41 wild wolves from Canada and northwest Montana were released in Yellowstone.
According to the park website, an estimated 400–450 wolves live within the entire Greater Yellowstone Ecosystem.
