“A landmark field guide for years to come… . Guides of this caliber come once or twice in a lifetime, and I highly recommend California Amphibian and Reptiles as a capstone reference in your library.”—Howard O.

Hansen and Shedd’s California Amphibians and Reptiles is such a book… . [It] contains a wealth of welcome natural history information.”—Tom Lott, Bulletin of the Chicago Herpetological Society“The quality of the information is impeccable - detailed, informative, laudatory, complete, from the introductory segments to the taxonomic notes, from the discussion of threats to the last page of the index.”—David M. Gascoigne, Travels with Birds“A MUST-HAVE for anyone with an interest in California’s amphibians and reptiles!”—Ian Paulsen, The Birdbooker Report“A beautiful book that’s a must-read for resident and visiting herpers of California.”—Repitile Database, Reptile Database“Highly illustrated and extremely well-illustrated.”—Steven J. R. Allain, Reptiles & Amphibians“This book stands as a definitive field guide and a significant contribution to the broader understanding of California’s herpetofauna.
