Book excerpt: Historical records and intensive field surveys 1975-77 provided information on the population history, ecology, and current status of wolves (Canis lupus) in Yellowstone National Park and vicinity. Wolves occurred in unknown but seemingly low densities during the latter 1800s in several areas of Yellowstone where they were controlled periodically until 1926. Populations apparently began increasing about 1912, primarily in the northeast, and may have reached nonequilibrium levels of 30-40 animals (postwhelping). Intensive control 1914-26 removed at least 136 wolves, including about 80 pups. During this period Yellowstone wolves characteristically lived in packs of 3-16 members, some of which followed the ungulates in their seasonal migrations. Litters averaging 7.8 were born in late March and April, primarily in the north central sector of the park. Limited evidence suggests that elk (Cervus elaphus) were important food for wolves during all seasons. Wolves either survived the control era or moved in shortly thereafter for singles, pairs, and a pack of four were reported the following decade. Resident wolf packs, however, were eliminated from Yellowstone National Park by the l940s. Large canids have been sighted intermittently to the present, but their identity has not been established. Singles and pairs comprised 89% of 116 "probable" reports over the past 50 years. Speculation about factors limiting the Yellowstone wolf population considers its relative geographic isolation from viable wolf populations and possible genetic problems (including wolf-coyote hybridization) associated with prolonged minimal population status. A transplant of wolves from British Columbia or Alberta, or perhaps Minnesota, is recommended to restore a viable population of this native predator to Yellowstone National Park.
