Ecosystem Geography

The first edition of this book, Ecosystem Geography, examined the distribution of ecosystems at different scales, and the processes that have differentiated them. It presented the principles for ecosystems mapping and explored the connections between ecosystem geography, conservation, and management. Ecosystem Geography was written in 1996, at a time when few published materials on ecosystem geography were available, and none had systematically elaborated the principles underlying the mapping of ecosystems in a form accessible to advanced students and practitioners. This second edition, Ecosystem Geography: From Ecoregions to Sites, builds on the strengths of its predecessor, incorporating new information and clarifying concepts presented in the first edition. New sections address how ecoregion boundaries were determined, ecoregion redistribution under climate change, ecosystem processes (such as fire regimes), empirical versus genetic approaches to classification, and human modification to ecosystems, such as through the introduction of invasive species.

From reviews of the first edition:

"An important book, richly illustrated with clear diagrams, maps, and photos. A major contribution to ecosystem ecology and an essential acquisition." -Choice

"The new 'ecosystem management' demands an understanding of ecosystems and the relationships between them. In short, it requires a sound geographical knowledge of ecosystems. Ecosystem Geography lays a firm foundation for such knowledge." -Progress in Physical Geography

"The book is essential reading for ecologists and natural area managers interested in ecosystem management and understanding how their landscapes fit into the larger picture regionally, continentally, and globally." -Natural Areas Journal

About the Author: Robert G. Bailey is a geographer with the United States Forest Service, Rocky Mountain Research Station, in Fort Collins, Colorado, and the former leader of the agency's Ecosystem Management Analysis Center. His work involves the application of ecosystem geography to ecological planning and design.

Texte du rabat

This book outlines a system that subdivides the Earth into a hierarchy of increasingly finer-scale ecosystems that can serve as a consistent framework for ecological analysis and management. The system consists of a three-part, nested hierarchy of ecosystem units and associated mapping criteria. This new edition has been updated throughout with new text, figures, diagrams, photographs, and tables.
