Book Description
Natural resource managers face a complex decision-making environment characterized by the potential occurrence of rapid and abrupt ecological change. These abrupt changes are poorly accommodated by traditional natural resource planning and decision-making processes. As recognition of threshold processes has increased, contemporary models of ecological systems have been modified to better represent a broader range of ecological system dynamics. Key conceptual advances associated with the ideas of non-linear responses, the existence of multiple ecological stable states and critical thresholds are more likely the rule than the exception in ecological systems. Once an ecological threshold is crossed, the ecosystem in question is not likely to return to its previous state. There are many examples and a general consensus that climatic disruptions will drive now stable systems across ecological thresholds. This book provides professional resource managers with a broad general decision framework that illustrates the utility of including ecological threshold concepts in natural resource management. It gives an entry into the literature in this rapidly evolving concept, with descriptions and discussion of the promising statistical approaches for threshold detection and demonstrations of the utility of the threshold framework via a series of case studies.

Book Description
Scientists have been warning for years that human activity is heating up the planet and climate change is under way. We are only just beginning to acknowledge the serious effects this will have on all life on Earth. The federal government is crafting broad-scale strategies to protect wildland ecosystems from the worst effects of climate change. One of the greatest challenges is to get the latest science into the hands of resource managers entrusted with vulnerable wildland ecosystems. This book examines climate and land-use changes in montane environments, assesses the vulnerability of species and ecosystems to these changes, and provides resource managers with collaborative management approaches to mitigate expected impacts. Climate Change in Wildlands proposes a new kind of collaboration between scientists and managers--a science-derived framework and common-sense approaches for keeping parks and protected areas healthy on a rapidly changing planet.

Book Description
At 14,259 feet, Longs Peak towers over Colorado’s northern Front Range. A prized location for mountaineering since the 1870s, Longs has been a place of astonishing climbing feats—and, unsurprisingly, of significant risk and harm. Careless and unlucky climbers have experienced serious injury and death on the peak, while their activities, equipment, and trash have damaged fragile alpine resources. As a site of outdoor adventure attracting mostly white people, Longs has mirrored the United States’ tenacious racial divides, even into the twenty-first century. In telling the history of Longs Peak and its climbers, Ruth M. Alexander shows how Rocky Mountain National Park, like the National Park Service (NPS), has struggled to contend with three fundamental obligations—to facilitate visitor enjoyment, protect natural resources, and manage the park as a site of democracy. Too often, it has treated these obligations as competing rather than complementary commitments, reflecting national discord over their meaning and value. Yet the history of Longs also shows us how, over time, climbers, the park, and the NPS have attempted to align these obligations in policy and practice. By putting mountain climbers and their relationship to Longs Peak and its rangers at the center of the story of Rocky Mountain National Park, Alexander exposes the significant role outdoor recreationists have had—as both citizens and privileged adventurers—in shaping the peak’s meaning, use, and management. Since 2000, the park has promoted climber enjoyment and safety, helped preserve the environment, facilitated tribal connections to the park, and attracted a more diverse group of visitors and climbers. Yet, Alexander argues, more work needs to be done. Alexander’s nuanced account of Longs Peak reveals the dangers of undermining national parks’ fundamental obligations and presents a powerful appeal to meet them fairly and fully.

Book Description
The authoritative guide to understanding and managing the ecological impacts of recreational activities in wildlands This third edition provides an updated and thorough examination of the ecological impacts of recreational use on wildlands and the best management practices to employ in places where recreation and preservation of natural conditions are both important - and often conflicting - objectives. Covering the latest research, this edition provides detailed information about the environmental changes that result from recreational use. It describes spatial patterns of impact and trends over time, then explores the factors that determine magnitude of impact, including amount of use, type and behavior of use, and environmental durability. Numerous examples, drawn from parks and recreation areas around the world, give readers insight into why certain areas are more heavily damaged than others, and demonstrate the techniques available to mitigate damage. The book incorporates both the first-hand experience of the authors and an exhaustive review of the world’s literature on the subject. Boxes provide quick access to important material, and further resources are referenced in an extensive bibliography. Essential reading for all park and protected area management professionals, this book is also a useful textbook for upper division undergraduate and graduate students on recreation ecology and recreation management courses.
