ABSTRACT
This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book examines some ecological history in the United States that undoubtedly influenced the early range managers and their concept that the ideal range condition was the pristine or climax condition. It outlines the general philosophy of the methodology for determining range condition, which has remained relatively unchanged. The book argues that the present system is based on valid ecological principles that are satisfactory as a basis for conservation and management planning and that drastic changes to a proven concept should not be made without proof that the proposed changes are an improvement. It describes a method for determining ‘livestock forage condition’ used by the Forest Service based on forage production and species composition. The book discusses a procedure developed by Forest Service researchers in which erosion can be recognized and measured on mountain rangelands.
