We wish to thank Dr. Robert Stebbins University of California, Berkely for allowing us to use his illustrations and range maps. He also provided updates on the taxonomy, status and distribution of amphibians in the Region and remains a leader in the field. His Field Guide to Western Reptiles and Amphibians remains the single, best source of information on these species. He is currently working on the fourth edition of this book which is scheduled to be released in 2002.
Dr. Charles R. Peterson graciously allowed us to use his identification photos and range information for those amphibians found in Idaho. He also obtained clearance from the following photographers: Charlotte Corkran, Edward D. Koch, Edmund D. Brodie, Jr., Edson Fichter, Michael McDonald, Jonathon M. Beck, Michael E. Dorcas, and Henry J. Fabian. We thank each of these people for allowing us to use their photographs.
Jeff Jundt Coordinator of the North American Reporting Center for Amphibian Malformations (NARCAM), Northern Prairie Wildlife Research Center, USGS, Jamestown, North Dakota, provided range maps and photographs for many of the species in this report. He also obtained clearances from Rick Fridell and Ted Hoberg to use their photographs. We are grateful for his assistance and enthusiasm.
Debra Patla, Biological Consultant, Driggs, Idaho, provided insightful suggestions on surveying and monitoring amphibians and was kind enough to provide a copy of the identification cards and poster she prepared for the Bridger-Teton National Forest.
Special thanks go to the following biologist with the Utah Division of Wildlife Resource: Rick Fridell, Paul Thompson, and Krissy Wilson. They have been actively surveying and reporting on amphibian species within the state of Utah and were very helpful in determining which species may be on National Forest lands.
We wish to thank Jerry Stein, Nevada Division of Wildlife for his assistance in determining the status and distribution of amphibians within the state of Nevada.
The Cornell Laboratory of Ornithology, Library of Natural Sounds graciously allowed us to use several recordings of frogs and toads found in the Intermountain Region on our web site. Biologists and naturalists are encouraged to purchase the "Frog and Toad Calls of the Rocky Mountains; Vanishing Voices" tape or CD from one of the sources listed in the Reference Cited section. We personally thank Marissa Hill and Greg Budney for their work on this effort.
I wish to thank David Prevedel for suggesting and then providing all the necessary resources for putting a version of this report on the Region 4 Home Page. I personally want to thank Dave Martini for all of his computer expertise and ideas for making this site a success.
We would like to thank all
of the other wildlife and fisheries biologists in the Intermountain West,
agency and non agency personnel alike, who were contacted for information
for this reports. A special thanks goes to Tanya Hoskins for
all her computer skills. Without her help, this report would
still be waiting for a server to decipher what I was trying to accomplish.
