Though coyotes will kill elk calves, they prey mainly on pocket gophers, voles, and other small mammals. Many biologists had speculated about how wolves might go about catching a beaver but there was little evidence to support their ideas. Like with wolves, beavers illustrate important conservation trade-offs for society. The loss of wolves caused far-reaching changes in the Yellowstone ecosystem: more elk and fewer willows. But the coyote’s small size kept them from regulating the park’s large ungulate populations, like wolves do. In Voyageurs National Park, USA, wolves appeared, based on where wolves killed beavers and how wolves spent time in beaver habitat, to hunt beavers by waiting for, and then ambushing beavers once they came on or near land (Gable et al.

A beaver colony is able to build a large lodge in only a couple of nights. Beavers do not hibernate and remain active throughout the winter. In addition, the wolves were taken off the endangered-species list in Idaho and Montana. These habitat types with their abundant and densely rooted vegetation in turn extract and store large amounts of atmospheric carbon. How wolves hunt beavers in these systems is largely unknown, however, because observing predation is challenging. In 1995, gray wolves were reintroduced to Yellowstone National Park, which is now one of the best places to see and hear them. How do wolves hunt beavers? Here's what to do if you see a wolf. Like with wolves, beavers illustrate important conservation trade-offs for society.
