This cooperative effort by USDA Forest Service Research and the National Forest System assesses the state of knowledge related to the conservation status of four forest carnivores in the western United States: American marten, fisher, lynx, and wolverine. The conservation assessment reviews the biology and ecology of these species. It also discusses management considerations stemming from what is known and identifies information needed. Overall, we found huge knowledge gaps that make it difficult to evaluate the species' conservation status.
Evidence is mounting that top carnivores and other large mammals play a pivotal role in regulating ecosystem health and function, yet those are the species that are most likely to have been eliminated by past human activities. In recent decades, numerous efforts have been undertaken to return some of the species that were previously extirpated on local or regional scales. Large Mammal Restoration brings together for the first time detailed case studies of those efforts, from restoring elk in Appalachia to returning bison herds to the Great Plains to the much-publicized effort to bring back the gray wolf to Yellowstone National Park. Together these case studies offer important lessons and new ways of thinking for wildlife managers and conservation biologists involved with restoration programs. Sections examine: approaches to determining the feasibility of a restoration program critical hands-on aspects of restoring large mammals obtaining public input into the process and gaining community support for programs the potential of some species to return without direct human intervention, and what can be done to facilitate that natural colonization An introductory chapter by Reed F. Noss explores some of the reasons for restoring large mammals, as well as some of the ecological and social complications, and a concluding overview by David S. Maehr discusses the evolutionary importance of large mammal restoration. Contributors include Paul C. Paquet, Barbara Dugelby, Steven H. Fritts, Paul R. Krausman, Larry D. Harris, Johnna Roy, and many others. Large Mammal Restoration brings together in a single volume essential information on the lessons learned from previous efforts, providing an invaluable resource for researchers and students of conservation biology and wildlife management as well as for policymakers, restoration advocates, and others involved with the planning or execution of a restoration program.
The first comprehensive treatment of North American rodents of conservation concern. This action plan summarizes the rodent fauna of North America and provides available information on every rodent taxon that has been considered to be of conservation concern by state, provincial and private conservation agencies and regional experts. It is hoped that the survey provided in this action plan will serve as a common ground for all these parties in drawing up conservation strategies for rodents.
Mech's landmark study of wolves and moose on Isle Royale National Park on Lake Superior. The author lived among them during the three-years of his research. Isle Royale is an isolated wilderness ecosystem which is perfect for scientific study.Dr. L. David Mech is the best-known and most highly regarded wolf researcher in the world. He works with the Biological Services Division, U.S. Geological Survey, and is also the author of several other books on wolves. He has studied wolves and their prey full-time since 1958, except for a four-year period when he studied radio-tracking. During this record-long career as a wolf biologist, he has published numerous books and articles; this book was originally published by the National Park Service in 1966."Mech is the foremost expert on wolves in this country, possibly in the world, hands down." - Smithsonian magazine
