Increasing levels of recreational use in wilderness, backcountry, and roadless areas has the potential to impact wildlife species, including those that depend on these protected areas for survival. Wildlife and wilderness managers will be more successful at reducing these impacts if they understand the potential impacts, factors affecting the magnitude of impacts, and available management strategies and implementation methods. In this reading list, we summarize over 230 books, articles, bibliographies, and Internet resources to provide managers with relevant research on backcountry recreation impacts on terrestrial wildlife amid the vast literature on this topic. The first section illustrates the importance of considering backcountry recreation impacts on wildlife, both for wildlife conservation and enhancement of wilderness visitor experiences. The second section reviews important concepts such as the types of impacts, methods for assessing them, and models for understanding these impacts. The third section provides an overview of field studies that documents recreation impacts on specific wildlife species and taxonomic groups. The fourth section contains information on management planning frameworks and specific techniques that may be useful for minimizing impacts of backcountry recreation to wildlife. The final section offers Internet resources and previous bibliographies related to the topic.

The large increase in outdoor recreation activity over the last 50 years has been recognized as a potentially serious threat to North American wildlife populations. Threats to wildlife in wilderness are a concern to backcountry recreationists as well as the American public. The protection of wildlife habitat and endangered species was one of the most highly valued benefits of wilderness according to a telephone survey of approximately 1,900 people in the United States (Cordell and others 1998). Many backcountry recreation users cite the opportunity to view wildlife as an important part of their wilderness experience. Threats to wildlife in wilderness are also a concern for wildlife preservation. Wilderness often provides a refuge for wildlife amid a matrix of more intensively developed lands, and is especially valuable for wide-ranging species that are sensitive to human disturbance and those that depend on special habitats found predominantly in wilderness (Hendee and Mattson 2002). Impacts of recreation on wildlife include increased energetic demands during critical periods of the year, loss of habitat through avoidance of areas of human activity, exposure to predators while avoiding humans, and loss of habitat through changes in vegetation resulting from recreation activities (Knight and Gutzwiller 1995). If widespread, cumulative impacts on individuals of a species may ultimately affect local and regional populations. Changes in species' populations may affect wildlife communities, especially if the impacted species have strong interactions with other species. The management of wilderness recreation impacts on wildlife in designated wilderness is complicated by the potentially conflicting mandates of The Wilderness Act of 1964 [Public Law 88-577]. The Act mandates the preservation of natural conditions in wilderness while requiring managers to provide opportunities for primitive recreation. However, when recreation affects wildlife species, populations, or communities, it can hinder the preservation of natural conditions. To address the dual mandates, appropriate wilderness recreational activities must not only be provided, but must be managed to minimize their impacts on wildlife, and more broadly, to wilderness ecosystems. Wilderness managers can use direct approaches such as restricting visitor numbers, activities, or access in some areas. In backcountry areas outside of designated wilderness, manipulating wildlife and wildlife habitat may be appropriate. Indirect approaches may also be used, such as visitor education and the careful location and design of trails, trailheads, and adjacent roads and campgrounds. We have compiled this annotated list of references to help wildlife, wilderness, and recreation managers better understand backcountry recreation impacts on wildlife and be informed of the variety of management tools available for minimizing impacts. Managing recreation impacts on wildlife is an interdisciplinary issue, with management decisions affecting both wildlife and visitors. We have designed this reading list to cross disciplinary boundaries. The reading list includes literature from the wildlife discipline, such as papers needed to understand impacts on wildlife, as well as literature from the recreation discipline that is needed to understand recreation management techniques. We suggest the expansion of future research to include other animal species that may be important to local ecosystems and/or have restricted ranges that overlap extensively with areas of high recreational use. Finally, previous studies on wildlife responses to primitive recreational activities have focused mainly on hiking. Managers would benefit from additional research on activities such as horseback riding, rock climbing, cross-country skiing, and kayaking in marine coastal areas.

An authoritative guide to managing the ecological impacts of recreational activities on natural resources. The challenges facing today's recreation resource managers are both complex and daunting. Accommodating rapidly growing numbers of recreational visitors without sacrificing the ecological integrity of wildlands is a major challenge. Determining and planning for the limits of acceptable change and expanding services with little or no growth in natural resources or funding are major issues. Wildland Recreation, Second Edition provides solutions to these and other crucial recreational resource problems. Based upon its authors' extensive firsthand experience as well as their exhaustive review of the world literature on the subject, it provides up-to-date, detailed coverage of today's wildland recreation management issues, including: Ecological impacts of recreational activities on wildland resources Spatial and temporal patterns of recreational impacts Environmental durability, visitor use, and other key factors The limits of acceptable change, long-term monitoring, and impacts on wildlife Social and economic factors associated with managing impacts Alternative approaches to wildland recreation resource management Recent trends in satisfying increased demand for outdoor recreational opportunities International perspectives on recreational wildland management and ecotourism Like its best-selling predecessor, Wildland Recreation, Second Edition is a valuable working resource for wildland recreation management professionals and a comprehensive course text for students of forest and natural resources recreation, park management, environmental conservation, and related disciplines.

Wildlife and Recreationists defines and clarifies the issues surrounding the conflict between outdoor recreation and the health and well-being of wildlife and ecosystems. Contributors to the volume consider both direct and indirect effects of widlife-recreationist interactions, including: wildlife responses to disturbance, and the origins of these responses how specific recreational activities affect diverse types of wildlife the human dimensions of managing recreationists the economic importance of outdoor recreation how wildlife and recreationists might be able to coexist The book is a useful synthesis of what is known concerning wildlife and recreation. More important, it addresses both research needs and management options to minimize conflicts.

This book describes the state of the art of tourism planning and management in national parks and protected areas. It also provides guidelines for best practice in tourism operations. Other objectives are to: Describe case studies and guidelines that contribute to conservation of biological diversity; consider the role of local communities within or near these areas; outline the development of tourism infrastructure and services; discuss visitor management; provide guidelines to enhance the quality of the tourism experience. The focus is global and the book will appeal to both academics and practitioners.
