The need for cooperation among government agencies as well as an interdisciplinary approach to the increasingly challenging and complicated problem of managing park and wilderness areas prompted the University of Washington College of Forest Resources, the National Park Service, and the Forest Service to sponsor an ecosystem management workshop for scientists, planners, and managers. To develop an improved conceptual approach to managing change in ecosystems crossing natural and political boundaries, the workshop focused on defining terms, uncovering areas of misunderstanding and barriers to cooperation, and developing methods to determine the most important problems and issues. Three needs emerged from the prioritization process: a precise definition of the management objectives for park and wilderness lands and how to integrate them with objectives for surrounding lands, nationally as well as site-specific; more information about physical, biological, and social components of park and wilderness ecosystems from both sides of political boundaries; and key indicators of ecosystem condition as well as methods for evaluating management effectiveness. All of these common themes point to a need for more precise direction in management goal setting and more accurate assessment of progress toward goals. The book includes an introductory chapter by the editors and summary in which they outline a direction for ecosystem management in the next critical decades. The other chapters by individual contributors include studies on laws governing park and wilderness lands, paleoecological records that reveal the historic effects of climatic variations on vegetation change, succession and natural disturbance in relation to the problems of what can and should be preserved, managing ecosystems for large populations of vertebrates, the management of large carnivores, effects of air pollution, lake acidification, human ecology and environmental management, the role of economics, cooperation in ecosystem management, and management challenges in Yellowstone National Park.

The central concept guiding the management of parks and wilderness over the past century has been “naturalness”—to a large extent the explicit purpose in establishing these special areas was to keep them in their “natural” state. But what does that mean, particularly as the effects of stressors such as habitat fragmentation, altered disturbance regimes, pollution, invasive species, and climate change become both more pronounced and more pervasive? Beyond Naturalness brings together leading scientists and policymakers to explore the concept of naturalness, its varied meanings, and the extent to which it provides adequate guidance regarding where, when, and how managers should intervene in ecosystem processes to protect park and wilderness values. The main conclusion is the idea that naturalness will continue to provide an important touchstone for protected area conservation, but that more specific goals and objectives are needed to guide stewardship. The issues considered in Beyond Naturalness are central not just to conservation of parks, but to many areas of ecological thinking—including the fields of conservation biology and ecological restoration—and represent the cutting edge of discussions of both values and practice in the twenty-first century. This bookoffers excellent writing and focus, along with remarkable clarity of thought on some of the difficult questions being raised in light of new and changing stressors such as global environmental climate change.

A pandora moth outbreak in Arizona was studied from 1979 to 1985 to determine the moth's life cycle, densities, and distribution of life stages, larval and adult behavior, effects of the defoliation, sampling procedures, importance of biotic mortality factors, and the effectiveness of insecticides. This report summarizes the available published and unpublished information on the outbreak.
