The most recent data available (end of 2013) indicate that the NRM wolf population contains at least 1,691 wolves, at least 320 packs, and at least 78 breeding pairs. This population has exceeded its recovery goals since 2002. By every biological measure the NRM wolf population is recovered and remains secure under State management. Long-term, the Service expects the entire NRM population to maintain a long-term average of around 1,000 wolves. These wolves represent a 400-mile southern range extension of a vast contiguous wolf population that numbers over 12,000 wolves in western Canada and about 65,000 wolves across all of Canada and Alaska.

All you need to know about Wolves. Yellowstone National Park - Potential Interactions Between Bears & Wolves. With the reintroduction of gray wolves (Canis lupus) to Yellowstone National Park (YNP), much interest has been shown regarding the effects of a restored wolf population on both grizzly bears (Ursus arctos horribilis) and black bears (Ursus americanus).

Yellowstone National Park - Potential Interactions Between Bears & Wolves

Grizzly bears, black bears, and gray wolves have historically coexisted in much of the same range throughout a large portion of North America (Brown 1993). Most interactions between the three species involve food sources and are usually characterized by mutual avoidance (Servheen and Knight 1990). The behavior of bears and wolves during interactions with each other are dependent upon many variables such as age, sex and reproductive status, prey availability, hunger and aggressiveness, numbers of animals, and previous experience in interacting with the other species (Servheen and Knight 1990).

Most serious interactions between the species occur around wolf dens (Peterson et al. 1984). Literature Cited Brown, G. 1993. Haber, G.C. 1987. Basic Facts About Gray Wolves. Gray wolves range in color from grizzled gray or black to all-white.

The carcasses of their prey also help to redistribute nutrients and provide food for other wildlife species, like grizzly bears and scavengers.
