The Rocky Mountain West is largely arid and steep, with ecological scars from past human use visible for hundreds of years. Just how damaging were the past 150 years of activity? How do current rates of disturbance compare with past mining, grazing, and water diversion activities? In the face of constant change, what constitutes a "natural" ecosystem? And can ahigh quality of life be achieved for both human and natural communities inthis region? Rocky Mountain Futures presents a comprehensive and wide-ranging examination of the ecological consequences of past, current, and future human activities in the Rocky Mountain region of the United States and Canada. The book brings together 32 leading ecologists, geographers, and other scientists and researchers to present an objective assessment of thecumulative effects of human activity on the region's ecological health andto consider changes wrought by past human use. This combined view of past and present reveals where Rocky Mountain ecosystems are heading, and the authors project what the future holds based upon current economic and social trends and the patterns that emerge from them. The book: examines the biogeographic and paleoenvironmental setting and, historical climate that have shaped Rocky Mountain ecosystems, traces the direct human influences on landscapes and ecosystems over the past 150 years, explores the cumulative effects of past, present, and projected future human activities on tundra, subalpine and montane forests, valleys, grasslands, and waters, offers case studies that illustrate specific examples of human fluence and current eff orts to restore the environment Case studies focus on northern New Mexico, Summit County, Colorado, Flathead Valley, Montana, and Alberta, Canada.
