Greater Yellowstone's Mountain Ungulates: a contrast in management histories and challenges is authored by a team of 18 wildlife professionals from federal and state government agencies and academic institutions in and around the Greater Yellowstone area. All have first-hand experience with conserving and managing mountain goats and bighorn sheep in the region. These experts have combined their knowledge and experiences to provide a non-technical narrative that describes the history, ecology, and management of these two iconic large mammals in the region. Much of the information conveyed in the chapters represents the culmination of an intensive 12-year collaborative research program that represents the largest coordinated effort to study the two species ever conducted. The 260-page book contains 9 chapters and is richly illustrated with 120 photographs and maps.
