"This report is a summary of the presence and absence of coho salmon, Oncorhynchus kisutch, in streams in the Central California Coast Evolutionary Significant Unit (ESU). Only streams with historical records of coho occupancy are considered. It has been prepared to assist in Endangered Species Act activities... Presence absence data used here come from surveys conducted for this study and fron data collected by other researchers. A preliminary report of this data, which included only approximately one-half of these streams, was published earlier... to meet earlier listing requirements."--p.Abstract.

In 1988 the U.S. Fish and Wildlife Service listed two endemic fishes of the upper Klamath River basin of Oregon and California, the sucker and the Lost River sucker, as endangered under the federal Endangered Species Act (ESA). In 1997, the National Marine Fisheries Service added the Southern Oregon Northern coastal California (SONCC) coho salmon as a threatened species to the list. The leading factors attributed to the decline of these species were overfishing, blockage of migration, entrainment by water management structures, habitat degradation, nonnative species, and poor water quality. Endangered and Threatened Fishes of the Klamath River Basin addresses the scientific aspects related to the continued survival of coho salmon and shortnose and Lost River suckers in the Klamath River. The book further examines and identifies gaps in the knowledge and scientific information needed for recovery of the listed species and proves an assessment of scientific considerations relevant to strategies for promoting the recovery of those species.
