This conference brought together scientists and managers from government, universities, and private organizations to examine the biological diversity and management challenges of the unique "sky island" ecosystems of the mountains of the southwestern U.S. and northwestern Mexico.

Illustrated.
In the Western U.S., the forest carnivores in this assessment are limited to boreal forest ecosystems. These forests are characterized by extensive landscapes with a component of structurally complex, mesic coniferous stands that are characteristic of late stages of forest development. This report assesses the scientific basis for conserving the American marten, fisher, lynx, & wolverine. It consists of literature reviews for each species & a discussion of management considerations & information needs. Comprehensive!
In this lively, historically accurate account, David E. Brown chronicles the demise of the grizzly bear in the Southwest. He presents the personal narratives of those who knew grizzlies, accounts of hunters and administrators in wildlife management agencies, and the popular legends and lore of the grizzly that one would hear around the campfire. Scientists, Southwest historians, and those interested in America’s wildlife will appreciate this readable study of the bear’s life history and of the unique spirit of adventure associated with the grizzly bear-a spirit that passed from southwest game ranges with the expirpation of the species in the first half of this century. This edition includes a new foreword by Charles Jonkel and a new preface, in which the author discusses the latest developments in the debate over the grizzly’s place in the Southwest.
