Beautifully crafted, high quality, sewn, 4 color guidebook. Part of a multiple book series of books on travel through America's beautiful and historic backcountry. Directions and maps to 2,970 miles of routes that travel through the beautiful mountain regions of Big Sur, across the arid Mojave Desert, and straight into the heart of the aptly named Death Valley. Trail history comes alive through the accounts of Spanish Missionaries; eager prospectors looking to cash in during California's gold rush; and legends of lost mines. Includes wildlife information and photographs to help readers identify the great variety of native birds, plants, and animal they are likely to see. Contains 153 trails, 640 pages, and 645 photos.

This volume presents a body of research conducted over more than thirty years, including an intensive interdisciplinary five-year study begun in 1991. Chapters include studies of the relationships of biogeography and climate to the region's air pollution, the chemical and physiological mechanisms of ozone injury, as well as the impacts of nitrogen-containing pollutants and natural stresses on polluted forests.

Both fire and climatic variability have monumental impacts on the dynamics of temperate ecosystems. These impacts can sometimes be extreme or devastating as seen in recent El Nino/La Nina cycles and in uncontrolled fire occurrences. This volume brings together research conducted in western North and South America, areas of a great deal of collaborative work on the influence of people and climate change on fire regimes. In order to give perspective to patterns of change over time, it emphasizes the integration of paleoecological studies with studies of modern ecosystems. Data from a range of spatial scales, from individual plants to communities and ecosystems to landscape and regional levels, are included. Contributions come from fire ecology, paleoecology, biogeography, paleoclimatology, landscape and ecosystem ecology, ecological modeling, forest management, plant community ecology and plant morphology. The book gives a synthetic overview of methods, data and simulation models for evaluating fire regime processes in forests, shrublands and woodlands and assembles case studies of fire, climate and land use histories. The unique approach of this book gives researchers the benefits of a north-south comparison as well as the integration of paleoecological histories, current ecosystem dynamics and modeling of future changes.
