Book excerpt: "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.

Book excerpt: 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 excerpt: "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.

This book was released on 2012 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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.

Available in PDF, EPUB and Kindle. Book excerpt: The coho salmon (Oncorhynchus kisutch) Central California Coast evolutionary significant unit (CCCESU) has declined from an estimated 50,000-125,000 adult returns to only 500 spawning adults, and is at high risk for extinction. Lagunitas Creek (Marin County, CA) supports 10% of the remaining population, but much of the watershed has incised stream banks and disconnected floodplains. Previous studies have implicated overwintering habitat for juveniles as a limiting factor and the priority for restoration efforts. Good overwintering habitat is characterized by complex channel form, refugia from predators, connected floodplains, and riparian vegetation. I used data derived from Light Detection and Ranging (LIDAR) to compare the floodplain height above river (HAR), vegetation height, and plant community type attributes in areas of Lagunitas Creek where coho juveniles are successfully overwintering and areas with poor smolt production. I found that 72.2% of the Lagunitas floodplain is five meters or less above base flow, comprised of 24.2% lower (0-2m) and 47.9% upper (2-5m) floodplain. The Tocaloma reach supported the most lower floodplain habitat, while the Point-Reyes-Nicasio reach had the greatest amount of upper floodplain My results, linking the floodplain elevation attributes to the plant height and community type, suggest many sections of the Lagunitas Creek can be restored as overwintering habitat for coho salmon.

Download or read book Inland Fishes of California written by Peter B. Moyle and published by Univ of California Press. This book was released on 2002-05-21 with total page 533 pages. Available in PDF, EPUB and Kindle. Book excerpt: When the first edition of Inland Fishes of California was published in 1976, it was a benchmark reference. Since that time, our knowledge of California's freshwater fishes has dramatically increased. This completely revised edition incorporates a vast amount of new information and creates a fresh synthesis of the historical data. Written by the leading expert on California's freshwater fishes and illustrated with beautiful line drawings, this compendium is the single best source for understanding and identifying the state's freshwater fishes. It is an essential resource for anyone who needs to have accurate and detailed information on California's fishes at their fingertips. Since the 1870s, the state's native fishes have been joined by thirty-four alien species, which now dominate many bodies of water. This book treats both native and introduced species, first in a key for identification, and then in individual species accounts covering characteristics, taxonomy, names, distribution, and life history. Each account includes the author's personal assessment of how well the species is doing and problems associated with its management. Most of the native fishes are found only in California and show many wonderful adaptations for living in the state's diverse waters. Unfortunately, many are also in danger of extinction. The message underlying the first edition of this book was that we knew astonishingly little about many of California's inland fishes. Although our knowledge is increasing, full accounts of some native fishes may not be complete before they become extinct. Preventing the loss of native fishes is the major goal of this book, and Moyle makes important suggestions for conservation strategies as well as presenting up-to-date information on ecology, life history, and distribution. With this knowledge, preserving our native fishes becomes possible even in the face of the state's growing economy and population.
