Available in PDF, EPUB and Kindle. Book excerpt: Lauded in the New York Times science section as "a sweeping analysis of the ecosystems of the United States and Canada," this volume represents an unparalleled source of information and data for scientists and conservationists working in North America. Using a rigorous ecoregion-based approach, rather than the more common state-by-state analysis, a team of scientists from World Wildlife Fund has produced a stunning and comprehensive assessment of the current status of biodiversity in North America north of Mexico. Terrestrial Ecoregions of North America begins with six chapters that present the rationale for the ecoregion approach, describe the biological distinctiveness of North American ecoregions, assess the level of threats facing each, present a conservation agenda for the next decade, and set forth recommendations for preserving and restoring biodiversity. In addition, nineteen essays by leading scientists address specific topics such as the effect of cattle on riparian areas, and the problem of invasive exotic plant species. Following the main text are substantial appendixes that describe each ecoregion in detail, including information on: unique features of the ecoregion that set it apart from the others its biological distinctiveness, threats to habitats and wildlife, and important sites for conservation activities that enhance biodiversity conservation in the ecoregion conservation partners working in the ecoregion, including addresses and other contact information the relationship of the ecoregion to other classification schemes literature cited for that ecoregion One of the most useful and unique features of the book is the series of thirty full-color maps that present essential information about the ecoregions and the biodiversity they contain in a compelling and easily understood graphical format. The ecoregion-based approach has been adopted by many conservation groups as the most effective way to ward off massive losses of biodiversity, and this volume provides a road map to that important new strategy. With a significant number of previously unpublished data sets and new analytic approaches, Terrestrial Ecoregions of North America is both a guidebook for describing the biological wealth of the continent and a handbook for restoring and conserving it. It will be an essential reference for anyone concerned with biodiversity conservation in North America.

Book excerpt: This volume represents a first attempt at holistically classifying and mapping ecological regions across all three countries of the North American continent. A common analytical methodology is used to examine North American ecology at multiple scales, from large continental ecosystems to subdivisions of these that correlate more detailed physical and biological settings with human activities on two levels of successively smaller units. The volume begins with an overview of North America from an ecological perspective, concepts of ecological regionalization. This is followed by descriptions of the 15 broad ecological regions, including information on physical and biological setting and human activities. The final section presents case studies in applications of the ecological characterization methodology to environmental issues. The appendix includes a list of common and scientific names of selected species characteristic of the ecological regions.

Available in PDF, EPUB and Kindle. Book excerpt: Produced as a framework for organizing and interpreting environmental data for inventory, monitoring, and research efforts. The descriptions of the 20 ecoregions of Alaska contained in this guide were derived by synthesizing information on the geographic distribution of environmental factors such as climate, terrain, soils, and vegetation. The specific procedures and materials used to delineate the ecoregion boundaries are documented, and the environmental characteristics in each ecoregion are described. Accompanied by a full-color oversize map of the ecoregions, their boundaries, and transitional areas. 42 full-color photos.

Book excerpt: Excerpt from Description of the Ecoregions of the United States Public land management agencies are increasingly involved in regional and national long-range planning and in efforts to classify all lands according to their capabilities and availability to produce goods and services in a balanced national program. During the past few years, these agencies have generally recognized the need for a comprehensive system for classifying ecosystems as an aid to achieving quality land management. Regional variations in climate, vegetation, and landform are important in the development of ecosystems; and, often, different regions have very different management problems. For this reason, it is important to recognize regional differences at the highest level in the classification. This regionalization facilitates (1) planning at the national level, where it is necessary to study management problems and potential solutions on a regional basis; (2) organization and retrieval of data gathered in a resource inventory; and (3) interpreta tion of inventory data, including differences in indicator plants and animals among regions.
