Book Description
In this book, we document and evaluate the recovery of gray wolves (Canis lupus) in the Great Lakes region of the United States. The Great Lakes region is unique in that it was the only portion of the lower 48 states where wolves were never c- pletely extirpated. This region also contains the area where many of the first m- ern concepts of wolf conservation and research where developed. Early proponents of wolf conservation such as Aldo Leopold, Sigurd Olson, and Durward Allen lived and worked in the region. The longest ongoing research on wolf–prey relations (see Vucetich and Peterson, Chap. 3) and the first use of radio telemetry for studying wolves (see Mech, Chap. 2) occurred in the Great Lakes region. The Great Lakes region is the first place in the United States where “Endangered” wolf populations recovered. All three states (Minnesota, Wisconsin, and Michigan) developed ecologically and socially sound wolf conservation plans, and the federal government delisted the population of wolves in these states from the United States list of endangered and threatened species on March 12, 2007 (see Refsnider, Chap. 21). Wolf management reverted to the individual states at that time. Although this delisting has since been challenged, we believe that biological recovery of wolves has occurred and anticipate the delisting will be restored. This will be the first case of wolf conservation reverting from the federal government to the state conser- tion agencies in the United States.

Book Description
All royalties from sales of this book go to Yellowstone’s wolf recovery project Few animals inspire such a mixture of fear, curiosity, and wonder as the wolf. Highly regarded but often misunderstood, the wolf has as many friends as enemies, and its reintroduction into Yellowstone National Park has sparked both fascination and controversy. Early in Yellowstone’s history, wolves were thought supernaturally evil, and scores were destroyed. Northern Rocky Mountain wolves were native to Yellowstone when the park was established in 1872, but “predator control” led to determined eradication, and by the 1940s they were gone. Amid much fanfare, however, wolves were reintroduced to one of the nation’s oldest national parks in the 1990s. This comprehensive reference documents the prehistory, management, and nature of the Yellowstone wolf. Historian-naturalist Paul Schullery has assembled the voices of explorers, naturalists, park officials, tourists, lawmakers, and modern researchers to tell the story of what may be the most famous wolf population in the world. This unique book includes numerous scientific studies of interest to wolf enthusiasts and scholars of western wildlife issues, conservation, and national parks. In a new afterword, Schullery discusses recent developments in the recovery project.

Book Description
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.
