The history of wolves in Yellowstone includes the extirpation, absence and reintroduction of wild populations of the gray wolf (Canis lupus) to Yellowstone National Park and the Greater Yellowstone Ecosystem. When the park was created in 1872, wolf populations were already in decline in Montana, Wyoming and Idaho.
In recent years, viral videos online have spun new tales about the wolf, attributing immense ecological changes to the canine. Scientists debunk myth that Yellowstone wolves changed entire ...
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.
Adult wolves at Yellowstone were documented on video carting "toys" — in the form of bones of various shapes and sizes — back to their offspring. Adult wolves at Yellowstone were documented on ...
Because of overgrazing, deciduous woody plant species, such as upland aspen and riparian cottonwood, became seriously diminished. So, because the keystone predators, the wolves, had been removed from the Yellowstone-Idaho ecosystem, the ecosystem changed. This change affected other species as well.
The restoration of the gray wolf to the Yellowstone National Park not only restores an important ecosystem component (the wolf) and process (predation by wolves) to bring the park into better ecological balance, but it also is economically sound. After weighing the costs (including full reimbursement to ranchers for the loss of livestock) and ...
It is estimated that approximately 500 wolves are present now throughout the Greater Yellowstone Ecosystem. The wolves’ presence played a vital role in increasing the health and diversity of ...
A classic example of a terrestrial trophic cascade is the reintroduction of gray wolves (Canis lupus) to Yellowstone National Park, which reduced the number, and changed the behavior, of elk (Cervus canadensis). This in turn released several plant species from grazing pressure and subsequently led to the transformation of riparian ecosystems. [17]
