Discusses the temperate forest ecosystem and the role of the gray wolf in helping to maintain it, describing the wolf's place on the food chain and what would happen to the temperate forest if the gray wolf were to become extinct.

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.

Describes the physical characteristics, behavior, habitat, and endangered status of gray wolves.

Find out what a gray wolf has in common with a red fox or an African lion. Discover what sets a gray wolf apart from a manatee or a giant panda. Readers will compare and contrast key traits of gray wolves—their appearance, behavior, habitat, and life cycle—to traits of other mammals. Charts and sidebars support key ideas and provide details. Through gathering information about similarities and differences, readers will make connections and draw conclusions about what makes this animal a mammal and how mammals are alike and different from each other.

A long howl rises over the dark forest. It is a gray wolf calling for its pack! Gray wolves are intelligent creatures whose bodies and behaviors are adapted to thrive in the forest biome. This title features low-level text and striking photos to take readers on a journey into the life of a gray wolf. Maps and other features show off range, conservation status, life span, and diet.

It was 1978, and there had been no resident timber wolves in Wisconsin for twenty years. Still, packs were active in neighboring Minnesota, and there was the occasional rumor from Wisconsin's northwestern counties of wolf sign or sightings. Had wolves returned on their own to Wisconsin? Richard Thiel, then a college student with a passion for wolves, was determined to find out. Thus begins Keepers of the Wolves, Thiel's tale of his ten years at the center of efforts to track and protect the recovery of wolves in Northern Wisconsin. From his early efforts as a student enthusiast to his departure in 1989 from the post of wolf biologist for the Department of Natural Resources, Thiel conveys the wonder, frustrations, humor, and everyday hard work of field biologists, as well as the politics and public relations pitfalls that so often accompany their profession. We share in the excitement as Thiel and his colleagues find wolf tracks in the snow, howl in the forest night and are answered back, learn to safely trap wolves to attach radio collars, and track the packs' ranges by air from a cramped Piper Cub. We follow the stories of individual wolves and their packs as pups are born and die, wolves are shot by accident and by intent, ravages of canine parvovirus and hard winters take their toll, and young adults move on to new ranges. Believing he had left his beloved wolves behind, Thiel takes a new job as an environmental educator in central Wisconsin, but soon wolves follow. By 1999, there were an estimated 200 timber wolves in 54 packs in Wisconsin. This is a sequel to Dick Thiel's 1994 book, The Timber Wolf in Wisconsin: The Death and Life of a Majestic Predator. That book traced the wolf's history in Wisconsin, its near extinction, and the initial efforts to reestablish it in our state. Thiel's new book looks at how successful that program has been.

Discover how gray wolves hunt, where they call home, and how they raise their young.
