Although wolf packs once roamed from the Arctic tundra to Mexico, loss of habitat and extermination programs led to their demise throughout most of the United States by early in the s.

Inthe US Fish and Wildlife Service listed the northern Rocky Mountain wolf Canis lupus as an endangered species and designated Greater Yellowstone as one of three recovery areas.

From to41 wild wolves from Canada and northwest Montana were released in Yellowstone National Park. As expected, wolves from the growing population dispersed to establish territories outside the park where they are less protected from human-caused mortalities. Wolves are highly social animals and live in packs. Worldwide, pack size will depend on the articles on wolves and abundance of prey. In Yellowstone, average pack size is 10 individuals.

The pack is a complex social family, with older members often the alpha male and alpha female and subordinates, each having individual personality traits and roles within the pack. Packs defend their territory from other, invading packs by howling and scent marking with articles on wolves. Wolves consume a wide variety of prey, large and small. They efficiently hunt large prey that other predators cannot usually articles on wolves. They also kill bison.

Many other animals benefit from wolf kills. For example, when wolves kill an elk, ravens arrive almost immediately. Coyotes arrive soon after, waiting nearby until the wolves are sated. Bears will attempt to chase the wolves away, and are usually successful.

Many other animals—from magpies to invertebrates—consume the remains. That ratio reversed from toindicating changes in prey vulnerability and availability. The discovery of this change emphasizes the importance of long-term monitoring to understand predator-prey dynamics. Changes in wolf predation patterns and impacts on prey species like elk are inextricably linked to other factors, such as other predators, management of ungulates outside the park, and weather e. Weather patterns influence forage quality and availability, ultimately impacting elk nutritional condition.

Consequently, changes in prey selection and kill rates through time result from complex interactions among these factors. Current NPS research focusses on the relative factors driving wolf predation over the past two decades.

Occupying just 10 percent of the park, it is winter range for the biggest elk herd in Yellowstone and is arguably the most carnivore-rich area in North America. Early management of predators caused dynamic changes to the ecosystem. The reappearance of carnivores on the landscape has had significant and sometimes unexpected impacts on the resident grazers and their habitat. In the first years following wolf restoration, the population grew rapidly as the newly formed packs spread out to establish territories with sufficient prey.

The wolves have expanded their population and range, and now are found throughout the Greater Yellowstone Ecosystem. Disease periodically kills a number of pups and old adults.

Outbreaks of canine distemper have occurred in, articles on wolves, and Indistemper articles on wolves two-thirds of the pups within the park. Infectious canine hepatitis, canine parvovirus, and bordetella have also have been confirmed among Yellowstone wolves, but their effects on mortality are unknown.

Articles on wolves mange, an infection caused by the mite Sarcoptes scabieireached epidemic proportions among wolves on the northern range in This process articles on wolves initiate an extreme allergic reaction and cause the wolf to scratch the infected areas, which often results in hair loss and secondary infections.

By the end ofthe epidemic had mostly subsided; however, the infection is still present at lower prevalences throughout the park. Wolf packs are highly territorial and communicate with neighboring packs by scent-marking and howl- ing. Occasionally, packs encounter each other, and these interactions are typically aggressive, articles on wolves. Larger packs often defeat smaller groups, unless the small group has more old adult or adult male members.

Sixty-five percent of collared wolves are ultimately killed by rival packs. Most of the decrease has been in packs on the northern range, where it has been attributed primarily to the decline in the elk population and available territory. Canine distemper and sarcoptic mange have also been factors in the articles on wolves decline. Each year, park researchers capture a small proportion of wolves and fit them with radio tracking collars, articles on wolves. These collars enable researchers to gather data on an individual, articles on wolves, and also monitor the population as a whole to see how wolves are affecting other animals and plants within the park.

The gray wolf was removed from the endangered species list in in Idaho and Montana. They were delisted in Wyoming inand that decision was upheld on appeal in April Wolves are hunted in Idaho and Montana under state hunting regulations. Wonders abound in Yellowstone, though many come with an unfamiliar danger. Learn how to adventure through Yellowstone safely. Wolves are not normally a danger to humans, unless humans habituate them by providing them with food. No wolf has attacked a human in Yellowstone, articles on wolves, but a few attacks have occurred in other places.

Like coyotes, wolves can quickly learn to associate campgrounds, picnic areas, and roads with food. This can lead to aggressive behavior toward humans.

To date, eight wolves in Yellowstone National Park have become habituated to humans. Biologists successfully conducted aversive conditioning on some of them to discourage being close to humans, but articles on wolves have had to be killed. Learn more about this journey.

From to , 41 wild wolves from Canada and northwest Montana were released in Yellowstone National Park. As expected, wolves from the growing population dispersed to establish territories outside the park where they are less protected from human-caused mortalities. Gray wolves range in color from grizzled gray or black to all-white. Though humans nearly hunted wolves to extinction in the lower 48 states, northern gray wolves have returned to the Great Lakes, northern Rockies and Pacific Northwest. Wolves play a key role in keeping ecosystems healthy. They help keep deer and elk populations in check, which can benefit many other plant and animal species. Packs are making a comeback. That’s a thrill for wildlife lovers. But wolves are still wolves, killing cattle and elk. Many Westerners are angry.
