In this important book, experts in science, economics, and law discuss key resource managment issues in the Greater Yellowstone Ecosystem---among them the managment of fire, elk, wolves, and bison---using them as starting points to debate the matter in which humans should interact with the environment of this region. Generously illustrated with special archival photographs of the Yellowstone area, the book will be the major source of information on this area and a valuable resource for worldwide wildland preservation for years to come. This edition contains a postscript written specifically to bring readers up to date on developments affecting the Yellowstone ecosystem between 1990 and 1993.
