Rolf Peterson investigating the carcass of a coyote killed by a wolf in Yellowstone National Park, January 1996. Scientists have been researching and studying the impacts on the Yellowstone ecosystem since re-introduction in 1995. As the wolf population in the park has grown, the elk population, their favored prey, has declined.
O-Six (named after the year of her birth). [3] was for several years [2010 - 2012] the dominant breeding female of the Lamar Canyon pack in Yellowstone National Park.Born in 2006 in the Agate Creek pack to Agate Creek Wolves #113M (born a Chief Joseph Wolf in 1997) and Wolf #472F (born a Druid Peak wolf in 2000), [4] [5] [6] she was principally known by the year of her birth.

The wolf population in Mongolia suffered quite intensive hunting periods in the early years of the 20th century, with up to 18,000 wolves being killed each year in the 1930s and 1940s, under the big and wide-range wolf hunts fostered and planned by the government.
926F became a very popular subject for Yellowstone wolf watchers and photographers. [9] She was one of the stars of the “wolf-watching mecca” of Yellowstone [10] and was called “Queen of Wolves”. [11] In 2018, 926F ceded the role of alpha female to her daughter, who produced the first surviving pups in three years.
An estimated 15% of Canada and Alaska's wolf population of 6,000-7,000 is eliminated annually. (Canada's total wolf population is about 30,000.) Ontario ceased its wolf bounty system in 1972, though retaining a year-round open season for wolves. [2] In Alberta, wolves bounties are still offered by some local governments.
In recent years, however, Yellowstone's elk population has plummeted. The Northern Herd, the only herd that winters in the park, has declined from nearly 20,000 animals in 1994 to less than 4,000 in 2013. Ecologists have linked this decline to a declining population of cutthroat trout in Yellowstone Lake, caused by invasive lake trout. With ...
The gray wolf is the largest wild member of the canid family, with males averaging 43–45 kg (95–99 lb), and females 36–38.5 kg (79–85 lb). [6] It is the most specialized member of its genus in the direction of carnivory and hunting large game.
The wolf population in northwest Montana initially grew as a result of natural reproduction and dispersal to about 48 wolves by the end of 1994. [51] From 1995 to 1996, wolves from Alberta and British Columbia were reintroduced into Yellowstone National Park and Idaho and expanded their range into the northern Rocky Mountains and Pacific ...
