Book Description
"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.

Historical and Current Presence-absence Data of Coho Salmon (Oncorhynchus Kisutch) in the Central California Evolutionary Significant Unit

Book Description
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.

Book Description
"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.

Recovery Plan for the Evolutionarily Significant Unit of Central California Coast Coho Salmon
Author: United States. National Marine Fisheries Service

ISBN:
Category : Coho salmon
Languages : en
Pages : 338
Book Description
"Central California Coast (CCC) Evolutionarily Significant Unit (ESU) coho salmon are listed as endangered species under the Federal Endangered Species Act (ESA) due to a precipitous and ongoing decline in their population. Since their initial listing in 1996 by NOAA's National Marine Fisheries Service (NMFS), the population has continued to decline and the species is now very close to extinction. Under the ESA, a recovery plan (which is a non-regulatory document) must be developed and implemented for threatened or endangered species. The purpose of recovery plans is to provide a road map that focuses and prioritizes threat abatement and restoration actions necessary to recover, and eventually delist, a species"--Executive Summary.
