Abstract
The diversity of Pacific salmon (Oncorhynchus spp.) varies from north to south with the greatest diversity of species found in the intermediate latitudes (northern Oregon to southern Alaska). Pink (O. gorbuscha), chum (O. keta) and sockeye (O. nerka) salmon predominate in the northern part of the range of Pacific salmon (British Columbia and Alaska), while chinook (O. tshawytscha), coho (O. kisutch) and steelhead (O. mykiss) are stronger in the south (Washington, Oregon, Idaho and California). Reviews of the status of Pacific salmon in this book suggest that the health of salmon populations generally deteriorates in a southward direction. This is due partly to greater human-caused damage to freshwater habitats outside Alaska and to ocean productivity cycles creating unfavorable conditions off Washington, Oregon, and California. Degradation of freshwater habitats in the southern part of the range must be reversed before the next low ocean productivity cycle, and productive habitats in the northern part of the range should be protected in anticipation of low ocean productivity.
