Robert G. Bailey 
Ecosystem Geography 
From Ecoregions to Sites

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.
