Book Description
Fifty-six forested plant communities in the Lake Laberge Ecoregion, YukonTerritory, are described in terms of appearance, characteristic andassociated species, landform, soils successional status, and productivity. Aprimary objective was to describe the communities so that forest and landmanagers, land-use planners, environmental impact assessors, andd landscapearchitects could identify the communities in the field.

Book Description
The Yukon is a land of remarkable wilderness, diverse ecosystems, and profound beauty. It is also home to a unique assemblage of birds. As of 2002, 288 bird species have been documented in the Yukon, with 223 occurring regularly. They occupy an amazing range of habitats, from the most barren mountain peaks to lush valley bottom forests, and are an integral part of the cultural heritage of Yukon First Nations people. The vast areas of natural habitat with limited road access can make the study of birds challenging, but are key in defining the nature of birding in the Yukon. Birds of the Yukon Territory is the result of a decade-long project initiated to gather and share what is known about the Yukon's birdlife. Lavishly illustrated with 600 colour photographs and 223 hand-drawn bird illustrations, the book presents a wealth of information on bird distribution, migration and breeding chronology, nesting behaviour, and habitat use, and on conservation concerns. Two hundred and eighty-eight species of birds are documented, including 223 regular species, and 65 casual and accidental species. In compiling this meticulously researched volume, the authors consulted over 166,000 records in a database created by the Canadian Wildlife Service, with information dating back to 1861. S ections on birds in Aboriginal culture and history, and bird names in the Yukon First Nations and Inuvialuit languages, enhance the book, as do the numerous easily interpreted charts and graphs. Destined to become a basic reference work on the avifauna of the North, Birds of the Yukon Territory is a must-have for bird enthusiasts and anyone interested in the natural history of the Yukon and the North.

Book Description
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 Description
Ecological Land Classification (ELC) refers to the description of land resources at a range of spatial resolutions (i.e. global to local) and for a range of purposes or values. The emerging science of ELC is in fact a very carefully integrated blend of vegetation and earth sciences, climatology, cartography and ecology with a range of new technologies and methodologies including computer-based geographic information systems, remote sensing and simulation modelling. This publication defines the current `state-of-the-art' of ELC. It provides particular insight into the role of ELC in current and future forest resource planning and management, and emphasizes its application and usefulness at various spatial scales, for a variety of geographic locations, and under a range of management scenarios/constraints. The book is an invaluable and substantial reference source about the current trends in ELC and will be of particular value to ecologists, foresters, geographers, resource managers, wildlife biologists, GIS and remote sensing specialists, educators and students.

Book Description
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.
