Distribution of Mammals, Reptiles, and Amphibians by BLM Physiographic Regions and A.W. Küchler's Associations for the Eleven Western States

The material for this technical note was obtained from reviewing many of the existing publications on mammals, reptiles and amphibians of the territorial western continental United States. It is intended to be used with the Integrated Habitat Analysis System and Strategic Information System within the Bureau of Land Management.

The Physiographic Regions are based on the climate and landform delineations overlaid on A. W. Küchler' s 1975 map of the "Potential Natural Vegetation of the Conterminous United States." The reference to the Association number are the numbers for the 1975 map by A. W. Küchler mentioned above and enclosed in the jacket on the back cover. Reproduction permission has been granted by A. W. Küchler and the American Geographical Society, Broadway at 156 Street, New York,
New York 10032.

The purpose of this technical note is to consolidate in one volume a species and subspecies list of mammals, amphibians and reptiles to be used for a variety of reports needed by various agencies. This technical note is not to be considered a final document, but it is hoped to stimulate refinement, additions and further investigation into more specific habitat requirements and occurrence within habitat sites of individual species and/or subspecies.
