INTRODUCTION
This booklet, "Endemic Amphibians and Reptiles of the Colorado River System . . . a
Status Report," is the second publication of the Endemic Species Committee. The wide
acceptance of the first, covering the endemic fishes, led to this endeavor. Through
encouragement of the Colorado River Wildlife Council, fishery biologists from the seven basin
states compiled this status report of amphibians and reptiles occurring within the drainage.'
To ease difficulty with ever-changing nomenclature among the scientific community, Dr.
Robert C. Stebbins', A Field Guide to Western Reptiles and Amphibians, 1966, was the sole
reference utilized. To further minimize confusion, a defined list of terms was selected to refer-
ence species occurrence and status.'
The purpose of this booklet is education; it is intended to make the reader aware of the
status of endemic species, many of which have been affected by urbanization, habitat
destruction and commercialization.
It is hoped this list will provide a useful reference and encourage new interest and study of
this part of our natural heritage - the endemic amphibians and reptiles of the Colorado Riv-
er system.
