"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.

"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 this report, we consider population structure under historical conditions, by which we mean population structure under pristine conditions that existed greater than 200 years ago and would exist presently had anthropogenic disturbances associated with European-American civilization not occurred ... This report consists of four main chapters: this introductory chapter, and a chapter for each species that we consider. Throughout the report, we review information on data sets or analyses used in the course of this exercise that do not appear elsewhere in the literature. For the most part, however, data sets and analyses brought to bear in this report are presented in greater detail as journal articles or technical memoranda that are or shortly will be available"--Page 2-3.
