The analysis and management of ecosystems rely increasingly on sound geographical knowledge. Ecosystem Geography is a landmark contribution which brings the geographer's tools - maps, scales, boundaries, and units - to the study of ecosystems. The author, a senior geographer and program manager with the U.S. Forest Service, has distilled more than two decades of research on ecosystem mapping and classification. His work has had a growing influence on how government and academic scientists are using ecological data to monitor biodiversity, manage land holdings, and interpret the results of climatic change. Ecosystem Geography features spectacular graphics, including diagrams, photographs, and abundant maps. It will be welcomed by ecologists, geographers, land and resource specialists, and anyone involved in the study or ecosystems.
