Book Description
Whitebark pine is a dominant feature of western high-mountain regions, offering an important source of food and high-quality habitat for species ranging from Clark's nutcracker to the grizzly bear. But in the northwestern United States and southwestern Canada, much of the whitebark pine is disappearing. Why is a high-mountain species found in places rarely disturbed by humans in trouble? And what can be done about it.Whitebark Pine Communities addresses those questions, explaining how a combination of altered fire regimes and fungal infestation is leading to a rapid decline of this once abundant -- and ecologically vital -- species. Leading experts in the field explain what is known about whitebark pine communities and their ecological value, examine its precarious situation, and present the state of knowledge concerning restoration alternatives. The book. presents an overview of the ecology and status of whitebark pine communities offers a basic understanding of whitebark pine taxonomy, distribution, and ecology, including environmental tolerances, community disturbance processes, regeneration processes, species interactions, and genetic population structure identifies the threats to whitebark pine communities explains the need for management intervention surveys the extent of impact and losses to dateMore importantly, the book clearly shows that the knowledge and management tools are available to restore whitebark pine communities both locally and on a significant scale regionally, and it provides specific information about what actions can and must be taken.Whitebark Pine Communities offers a detailed portrait of the ecology of whitebark pine communities and the current threats to them. It brings together leading experts to provide in-depth information on research needs, management approaches, and restoration activities, and will be essential reading for ecologists, land managers, and anyone concerned with the health of forest ecosystems in the western United States.

Book Description
In The Bear Doesn’t Know, Paul Schullery—honored naturalist, storyteller, and former Yellowstone ranger—has given us a bear-lover’s book of wonders. It is rich in the joy, beauty, inspiration, and pure fun to be had during a life well lived in bear country. While exploring the cultural complications of an animal we have long both feared and adored, he chronicles the bumpy course of our coming to terms with the mysteries of bear ecology and behavior. Schullery brings to the matter of bears a long view—of our centuries-long and always-evolving perception of wild bears, of the scientific exploration of bear ecology and behavior, and of the sometimes bitter struggles to protect bear populations for the future. Featuring Schullery’s trademark gifts for historical inquiry and scientific translation, as well as for mixing humor with telling insight, Schullery enlivens The Bear Doesn’t Know with many of his own quirky tales of life in the wildlands of North America and in the obscure realms of bear folklore and literature. North America’s bears have become universally recognized symbols of wild landscapes and the struggles to preserve them. In this collection, Schullery illuminates and celebrates the bears and their world, making plain why they always have and always will matter so much to us.

Book Description
Endangered Species Recovery presents case studies of prominent species recovery programs in an attempt to explore and analyze their successes, failures, and problems, and to begin to find ways of improving the process. It is the first effort to engage social scientists as well as biologists in a wide-ranging analysis and discussion of endangered species conservation, and provides valuable insight into the policy and implementation framework of species recovery programs. The book features a unique integration of case studies with theory, and provides sound, practical ideas for improving endangered species policy implementation.

Book Description
American wildlife biologists first began fitting animals with radio transmitters in the 1950s. By the 1980s the practice had proven so useful to scientists and nonscientists alike that it became global. Wired Wilderness is the first book-length study of the origin, evolution, use, and impact of these now-commonplace tracking technologies. Combining approaches from environmental history, the history of science and technology, animal studies, and the cultural and political history of the United States, Etienne Benson traces the radio tracking of wild animals across a wide range of institutions, regions, and species and in a variety of contexts. He explains how hunters, animal-rights activists, and other conservation-minded groups gradually turned tagging from a tool for control into a conduit for connection with wildlife. Drawing on extensive archival research, interviews with wildlife biologists and engineers, and in-depth case studies of specific conservation issues—such as the management of deer, grouse, and other game animals in the upper Midwest and the conservation of tigers and rhinoceroses in Nepal—Benson illuminates telemetry's context-dependent uses and meanings as well as commonalities among tagging practices. Wired Wilderness traces the evolution of the modern wildlife biologist’s field practices and shows how the intense interest of nonscientists at once constrained and benefited the field. Scholars of and researchers involved in wildlife management will find this history both fascinating and revealing.
