Pacific salmon inhabit a vast ecosystem that encompasses the rivers
within and the ocean between coastal countries. From steep, cold
snowmelt streams to major tributaries, from estuaries to the deep
ocean, the range of Pacific salmon includes the Tachia River in
Taiwan, the permafrost zone of Chukotka that flows to the Chukchi
Sea, the vast expanse of the Pacific Ocean between Japan and
California, the streams and rivers of the Yukon Territory and
British Columbia, and the myriad waterways in Washington, Oregon,
Idaho, and California, as far south as Rio Santo Domingo in Baja
California. 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 stunning
full-page maps overlay the human, climatic, geological, and
environmental impacts on salmon populations.
