Amphibians and reptiles (herpetofauna) are a significant but much-neglected component of the natural economy of the province of Alberta. The Amphibians and Reptiles of Alberta, Second Edition continues both as a field guide and a comprehensive natural history, builds on the strengths of the first with a richly illustrated text and colour photographs of the species taken by renowned wildlife photographer Wayne Lynch. The Amphibians and Reptiles of Alberta, First Edition won an Emerald Award for Environmental Excellence and an award from the Book Publishers Association of Alberta. This second edition has been thoroughly revised and updated. Nomenclature has been changed to reflect current thinking in the field. New photographs have been added, and maps and illustrations have been updated. This is the essential reference for Alberta herpetofauna.
