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 With a significant number of previously unpublished data sets and new analytic approaches, Terrestrial Ecoregions of North America is both a guidebook for describing the biological wealth of the continent and a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.

Download or read book Ecological Regions of North America written by and published by . This book was released on 1997 with total page 92 pages. Available in PDF, EPUB and Kindle. 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.

This book was released on 2017-10-27 with total page 86 pages. Available in PDF, EPUB and Kindle. 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.

Download or read book Ecoregional Green Roofs written by Bruce Dvorak and published by Springer Nature. This book was released on 2021-02-05 with total page 626 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book studies the application of green roofs in ecoregions of the western United States and Canada. While green roofs were intended to sustain local or regional vegetation, this volume describes how green roofs in their modern form are typically planted with a low-diversity mix of sedums from Europe or Asia. The authors demonstrate how in the western USA and Canada many green roofs have been designed with native plants and have been found to thrive. Part I of this book covers theory and an overview of ecoregions and their implications for green roofs. In Part II vegetation from prairies, deserts, montane meadows, coastal meadows, and scrub and sub-alpine habitats are explored on seventy-three ecoregional green roofs. Case studies explore design concepts, materials, watering and maintenance, wildlife, plant species, and lessons learned. Part III covers an overview of ecoregional green roofs and a future outlook. This book is aimed at professionals, designers, researchers, students and educators with an interest in green roofs and the preservation of biodiversity.

Available in PDF, EPUB and Kindle. Book excerpt: Global warming and human-driven impacts are changing the World’s ecological zones. This book applies the principles described in Bailey’s Ecosystem Geography: From Ecoregions to Sites, 2nd ed. (Springer 2009, 1st ed. 1996) to describe and characterize the major terrestrial and aquatic ecological zones of the Earth. Bailey’s system for classifying these zones has been adopted by major organizations such as the U.S. Forest Service and The Nature Conservancy and this book is a significant contribution to a long tradition of classifying and studying the world’s ecological regions or ecoregions. It includes two color maps that show the major ecoregions of the continents and oceans. Also included are: - 106 illustrations with 55 in full color - A new chapter on mountains is included. - There are new sections that address concerns about how eco regions are changing under the relentless influence of humans and climate change - Another new feature is the discussion of using eco regional patterns to transfer research results and select sites for detecting climate change effects on ecosystem distribution - Use of ecoregional patterns to design monitoring networks and sustainable landscapes - Fire regimes in different regional ecosystems and their management implications.
