More than a field guide, this book is a compendium representing the expertise of more than 30 authors. Introductory chapters provide the reader with a foundation in amphibian biology. This book expands on a previous publication, Amphibians of Washington and Oregon, and the text now covers the entire Pacific Northwest region, from north-central California to the Yukon and Alaska, and from the Pacific Coast to Montana. Comprehensive coverage shows 46 species with color photos of all stages of life. Clear text, keys, maps, and illustrations will guide you through the exploration of the elusive amphibians of the Pacific Northwest.
