"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.

The Law Library presents the complete text of the Listing Endangered and Threatened Species - Threatened Status for Oregon Coast Coho Salmon Evolutionarily Significant Unit (US National Oceanic and Atmospheric Administration Regulation) (NOAA) (2018 Edition). Updated as of May 29, 2018 We, the National Marine Fisheries Service (NMFS), issue a final determination to retain the threatened listing for the Oregon Coast (OC) Evolutionarily Significant Unit (ESU) of coho salmon (Oncorhynchus kisutch) under the Endangered Species Act (ESA). This listing determination will supersede our February 11, 2008, listing determination for this ESU. Our February 11, 2008, determinations establishing protective regulations under ESA section 4(d) and designating critical habitat for this ESU remain in effect. This ebook contains: - The complete text of the Listing Endangered and Threatened Species - Threatened Status for Oregon Coast Coho Salmon Evolutionarily Significant Unit (US National Oceanic and Atmospheric Administration Regulation) (NOAA) (2018 Edition) - A dynamic table of content linking to each section - A table of contents in introduction presenting a general overview of the structure

A summary of the presence and absence of coho salmon, Oncorhynchus kisutch, in streams in the Central California Evolutionary Significant Unit (ESU) with historical records of this species has been prepared to assist in the Endangered Species Act listing process. Presence-absence data were used because of: 1) the short time frame indicated by the listing process, and 2) the use of presence-absence data in pre-listing documents. Presence-absence data used here come form surveys conducted for this study and from data collected by other researchers. Coho salmon were absent from 50% of the historical record streams. This figure is similar to reports by earlier researchers. The percent of historical record streams with coho salmon absent is highest in the highly urbanized San Francisco Bay and the lowest in coastal Marin County. Percent of absence was also high in Sonoma County, with other areas being roughly equal.

"The main purpose of technical recovery planning for Pacific salmon and steelhead is to produce biologically based viability criteria for listed Evolutionarily Significant Units (ESUs) that will be considered in setting recovery goals. These viability criteria, and the analyses from which they stem, must refer to specific populations and population groups (i.e., populations or groups of populations within a ESU). The purpose of this report is to describe the historical population structure of coho salmon in the Southern Oregon/Northern California Coast (SONCC) ESU in order to guide viability analyses, and to provide a historical context for other parties interested in recovering coho salmon in the geographic region. We collected and examined available information relevant to the question of population structure of coho salmon in the SONCC ESU, and we present that information here. Readers interested in the conclusions can refer to the abstract, Table 1, and Figure 9"--Preface.
