Elk are more hostile toward people during calving season in Yellowstone National Park. Here's what to know. Yellowstone National Park issues danger warning for tourists.
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%.

“It’s common for elk, bison and pronghorn to be at the school grounds, less so bears and wolves. It is very rare that we document wolves within the town’s developed footprint over the last ...
The Rocky Mountain elk was reintroduced in 1913 to Colorado from Wyoming after the near extinction of the regional herds. While overhunting is a significant contributing factor, the elk's near extinction is mainly attributed to human encroachment and destruction of their natural habitats and migratory corridors.
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 ...
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.
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]
