Publisher description: The North Pacific Rim nations--the United States, Canada, Russia, Japan, China, and the Koreas--enjoy vastly different economic, ecological, and cultural relationships with salmon and, until now, the types of data available to assess the abundance and biodiversity of these fish were almost as varied as the scientists who collect them. Atlas of Pacific Salmon is the first book to apply a common, newly calibrated yardstick to measure, across this broad ecosystem, the state of Pacific salmon, which have suffered precipitous declines in abundance and diversity in recent decades. The only map-based assessment of distribution and risk of extinction for seven species of Pacific salmon at one consistent scale, under one authorship, the Atlas is the result of five years' work by Xanthippe Augerot and other foremost experts in the field. Using state-of-the-art GIS mapping tools, this book offers a multidimensional view of Pacific salmon populations from a watershed perspective, through the natural boundaries in which the fish migrate, spawn, and mature. More than three dozen full-page maps overlay the human, climatic, geological, and environmental impacts on salmon populations.
