"Restoring Western Ranges and Wildlands" has had a fairly long gestation period. This final product of three volumes had its beginnings in 1983. At that time research administrators of the Intermountain Forest and Range Experiment Station (now part of the Rocky Mountain Research Station) had obtained funding from the Four Corners Regional Commission to produce a series of research summary syntheses to aid agriculture and natural resource values and management for the Four Corner States (Arizona, Colorado, New Mexico, and Utah), and surrounding areas. "Restoring Western Ranges and Wildlands" was intended to supplant the successful, out-of-print, "Restoring Big Game Range in Utah" with a broader geographic coverage and new knowledge gained during the intervening years. This work represents the continuing collaboration of the Rocky Mountain Research Station and the Utah Division of Wildlife Resources. It is believed that the materials presented here in a "how to, what with, and why" manner will be timely and relevant for land managers and student in rehabilitation and restoration of degraded Western wildlands for years into the future.
