As the wolf population in the park has grown, the elk population, their favored prey, has declined. Prior to Glacier National Park To Great Falls Mt, the EIS predicted that wolves would kill an average 12 elk per wolf annually. This estimate proved too low as wolves are now killing an average of 22 elk per wolf annually. Although wolf kills are directly attributable to declines in elk numbers, some research has shown that elk behavior has been significantly altered by wolf predation.
The constant presence of wolves have pushed elk into less favorable habitats, raised their stress level, lowered their nutrition and their overall birth rate. Since then, in andthe local coyote population went through a dramatic restructuring. Yellowstone coyotes have had to shift their territories as a result, moving from open meadows to steep terrain. Carcasses in the open no longer attract coyotes; when a coyote is chased on flat terrain, it is often killed.
As the wolf comes after it, the coyote will turn around and run uphill. Wolves, being Laramie Wy To Yellowstone National Park, cannot stop and the coyote gains a large lead.
Though physical confrontations between the two species are usually dominated by the larger wolves, coyotes have been known to attack wolves if they outnumber them. Both species will kill each other’s pups given the opportunity. These changes affect how often certain roots, buds, seeds and insects get eaten, which can alter the balance of local plant communities, and so on Laramie Wy To Yellowstone National Park the food chain all the way to fungi and microbes.
In response to the change in status, state wildlife authorities in Idaho and Montana enacted quota-based hunting seasons on wolves as part of their approved state Wolf Management Plans. Environmental groups objected to the delisting and the hunting seasons, but despite legal attempts to stop them Defenders of Wildlife et al.
During these hunts, Montana hunters legally killed a number of wolves in the Absaroka-Beartooth Wilderness known to frequent the northeast corner of the park. Initially, the effects of wolf predation on elk during the first five years of the recovery were not detected, as elk numbers were identical to those of — This is higher than the 12 ungulates per wolf rate predicted in the ESA.
When the issue of what subspecies to use for the introduction was raised, U. Fish and Wildlife Service representatives stated that the taxonomy of gray wolves had been revised numerous times, and that C. The rationale behind Brewster and Fritz’s favor was that wolves show little genetic diversity, and that the original population was extinct anyway. Doug Smith states that the size difference between the introduced wolves and the original wolves was actually only a percent difference and Minnesotan wolves had no experience with elk and bison and were not adapted to mountainous terrain.
