The eastern elk (Cervus canadensis canadensis) is an extinct subspecies or distinct population of elk that inhabited the northern and eastern United States, and southern Canada. The last eastern elk was shot in Pennsylvania on September 1, 1877. [1] [2] The subspecies was declared extinct by the United States Fish and Wildlife Service in 1880. [3]
A cow/calf winter herd is a herd that consists only of female elk and their young. In a normal winter, defined as one where there is a decent amount of snow fall, one study found that when the groups of cows and calves were safe from predation by wolves, about 75.6-83.0% of their diet was made up of graze whereas when wolves were present this number dropped to 61.6-69.4%.

For now, Yellowstone's mud pots will keep boiling, the hot springs will keep steaming, the geysers will keep spraying, the Earth will keep shaking and the fumaroles will keep venting.
Human caused deaths in the same period accounted for 8–30% of known deaths. Yellowstone elk comprise up to 92% of the winter diet of wolves, the overall kill rates of Yellowstone wolves on elk in winter being estimated at 22 ungulates per wolf annually. This is higher than the 12 ungulates per wolf rate predicted in the ESA. [50]
Video shows the intense moment a pack of wolves chases down a herd of more than 300 elk in Yellowstone National Park. The video follows the elk herd as it races away from wolves trailing behind it.
These lands provided winter range for elk and other ungulates. [4] By the 1970s, the grizzly bear's (Ursus arctos) range in and near the park became the first informal minimum boundary of a theoretical "Greater Yellowstone Ecosystem" that included at least 4,000,000 acres (16,000 km 2). Since then, definitions of the greater ecosystem's size ...
