This book was released on 2008 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Technical Recovery Team (TRT) for the North-Central California Coast Recovery Domain has been charged with developing biological viability criteria for each listed Evolutionarily Significant Unit (ESU) of salmon and Distinct Population Segment (DPS) of steelhead within the recovery domain. The viability criteria proposed in this report represent the TRT's recommendations as to the minimum population and ESU/DPS characteristics indicative of an ESU/DPS having a high probability of long-term (> 100 years) persistence. Our approach employs criteria representing three levels of biological organization: populations, diversity strata, and the ESU or DPS as a whole. Populations include both independent and dependent populations defined in Bjorkstedt et al. (2005), as modified in Appendix A of this report. Diversity strata are groups of geographically proximate populations that reflect the diversity of selective environments, phenotypes, and genetic variation across an ESU or DPS (Bjorkstedt et al. 2005). A viable ESU or DPS comprises sets of viable (and sometimes nonviable) populations that, by virtue of their size and spatial arrangement, result in a high probability of persistence over the long term. We provide background critical to understanding the context for viability criteria development in Chapter 1 of this report. Chapters 2 and 3 define viability criteria at the population and ESU/DPS levels, respectively. In Chapter 4, we apply the criteria to assess current viability, though with limited success due to the lack of appropriate, population-level time series of abundance. We emphasize that the focus of this document is looking forward to evaluating recovery, not assessment of current conditions"--Executive summary.

Available in PDF, EPUB and Kindle. Book excerpt: This long-anticipated reference and sourcebook for CaliforniaÕs remarkable ecological abundance provides an integrated assessment of each major ecosystem typeÑits distribution, structure, function, and management. A comprehensive synthesis of our knowledge about this biologically diverse state, Ecosystems of California covers the state from oceans to mountaintops using multiple lenses: past and present, flora and fauna, aquatic and terrestrial, natural and managed. Each chapter evaluates natural processes for a specific ecosystem, describes drivers of change, and discusses how that ecosystem may be altered in the future. This book also explores the drivers of CaliforniaÕs ecological patterns and the history of the stateÕs various ecosystems, outlining how the challenges of climate change and invasive species and opportunities for regulation and stewardship could potentially affect the stateÕs ecosystems. The text explicitly incorporates both human impacts and conservation and restoration efforts and shows how ecosystems support human well-being. Edited by two esteemed ecosystem ecologists and with overviews by leading experts on each ecosystem, this definitive work will be indispensable for natural resource management and conservation professionals as well as for undergraduate or graduate students of CaliforniaÕs environment and curious naturalists.

This book was released on 2016 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This report from the Southwest Fisheries Science Center covers 10 ESA-listed Evolutionarily Significant Units (ESUs) and Distinct Population Segments (DPSs) that lie wholly or partially in California. In this review, we consider 1) new information relevant to the delineation of ESU/DPS boundaries, and 2) new information on status and trends in abundance, productivity, spatial structure and diversity specifically addressed by viability criteria previously developed by Technical Recovery Teams (TRTs). These viability assessments summarize current information (through the 2014–2015 spawning year where available) with respect to the viability criteria developed by the TRTs. Consequently, the current assessments consider not only changes in populations that have occurred since the 2010 assessments but also the status of populations and ESUs/DPSs in relation to the viability criteria developed by the TRTs. For eight of the ESUs/DPSs (Southern Oregon/Northern California Coho Salmon, Central California Coast Coho Salmon, California Coastal Chinook Salmon, Northern California Steelhead, Central California Coast Steelhead, South-central California Steelhead, Southern California Steelhead, and California Central Valley Steelhead) the new information suggests that there has been no change in extinction risk since 2010 viability assessments. For two ESUs (Central Valley Spring-run Chinook Salmon, and Sacramento River Winter-run Chinook Salmon) the new information suggests a change in extinction risk. The viability of Central Valley Spring-run Chinook salmon appears to have improved since the 2010 assessment, but this ESU is far from being viable and is still facing relatively high extinction risk. The viability of Sacramento River Winter-run Chinook Salmon has been reduced and the ESU faces greater extinction risk since the 2010 assessment"--Executive summary.

Book excerpt: "The goal of this Recovery Plan is to prevent the extinction of South-Central California Coast steelhead (Oncorhynchus mykiss) in the wild and to ensure the long-term persistence of viable, selfsustaining, populations of steelhead distributed across the South-Central California Coast Steelhead (SCCCS) Distinct Population Segment (DPS). It is also the goal of this Recovery Plan to ensure a sustainable South-Central California steelhead sport fishery through the restoration of a suite of viable steelhead populations across the SCCCS DPS. Recovery of the SCCCS DPS will require the protection, restoration, and maintenance of a range of habitats throughout the DPS in order to allow the natural diversity of O. mykiss to be fully expressed (e.g., anadromous and resident forms, timing and frequency of runs, and dispersal between watersheds)"--Executive Summary.

Book excerpt: "This guidance document is designed to better assist those involved with salmon recovery in understanding the recovery monitoring needs and the associated level of certainty at the regional, local, and project levels. The recommendations included are for federal and state agencies, Indian tribes, local governments and watershed organizations participating within each evolutionarily significant unit (ESU) and distinct population segment (DPS) which are actively developing recovery plan monitoring programs, or are modifying existing monitoring. It is our intention that these recommendations will be considered as the desired level of monitoring to be conducted and will provide a consistency across recovery domains. Recommendations include monitoring that addresses all of the viable salmonid population (VSP) criteria and the listing factors and threats. Following are specific NOAA's National Marine Fisheries Service (NMFS) recommendations for monitoring, data collection, and reporting ESA information. The recommendations are not listed in order of importance, but by the logical chapters of the document. The recommendations are based upon scientific information available, but include policy decisions for what standard is attainable and reasonable. The relative importance of each recommendation is left to the reader to determine based upon their own circumstances and biological and physical conditions. This document is not intended as a step by step process to de-list a species."--Executive summary.

Available in PDF, EPUB and Kindle. Book excerpt: "In the fall of 2012, after consulting with a wide range of salmon recovery partners, NOAA Fisheries asked Oregon Consensus and the William D. Ruckelshaus Center (university-based, neutral, third-party institutions devoted to promoting collaborative governance and consensus-based public policy) to conduct an independent, impartial situation assessment to explore regional views about how best to approach comprehensive, long-term salmon and steelhead recovery in the Basin. The centers assembled an Assessment Team comprised of practitioners and academics from Washington, Oregon and Idaho. The Assessment Team conducted 206 semi-structured interviews with individuals selected for their knowledge of, engagement in, and/or concern for salmon recovery planning in the Basin. The overall goal of the assessment and this report is to provide a summary of key themes, issues and perspectives identified from the interviews, and to describe potential process options to better achieve desired outcomes regarding longterm salmon and steelhead recovery in the Basin. This report begins with an explanation of the assessment process, followed by a brief overview of recovery processes in the Basin. The report then presents a synthesis of information gained through the interviews, focusing on key themes. The last section presents a conceptual framework for assessing the salmon recovery system, along with key findings and process options for improving the system and addressing salmon and steelhead recovery in the long term. Supplemental information is provided in appendices."--Executive summary (page 1).
Download or read book Potential Steelhead Over summering Habitat in the South central southern California Coast Recovery Domain written by David Alan Boughton and published by . This book was released on 2006 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recovery efforts for steelhead are likely to be aided by maps of potential habitat. In the South-Central/Southern California Coast recovery domain, the most geographically restricted habitat type is probably oversummering habitat, due to the Mediterranean climate and the general aridity of the region. Here we develop a model of potential oversummering habitat and map it in a Geographic Information System, using the method of environmental envelopes. Under the envelope method, predicted habitat is the set of stream segments falling within the same range of conditions that encapsulate the known occurrences of the species. Thus the method is based on known occurrences described in museum records, environmental reports, scientific papers, and other credible sources. The axes for the "range of conditions" are geomorphic, hydrologic, and climatic features thought to control the broad-scale suitability of stream reaches under natural (unmanaged, unimpaired) conditions. The specific predictors for potential habitat were stream gradient, summer mean discharge, summer temperature, valley width relative to mean discharge, and whether or not the reach occurred in alluvial soils. The resulting model predicts over-summering habitat throughout the recovery domain, as illustrated in 10 synoptic maps included in this report. Various limitations of the model are described at length.
Download or read book Columbia River Basin Salmon and Steelhead written by and published by . This book was released on 2002 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Before 1850, an estimated 16 million salmon and steelhead returned to the Columbia River Basin annually to spawn. Over the past 25 years, the number of salmon and steelhead returning to the Columbia River Basin has averaged only 660,000 per year although annual population levels have varied widely. Factors such as over-harvesting, construction and operation of dams, degradation of spawning habitat, increased human population, and unfavorable weather and ocean conditions have contributed to the long-term decline. The population decline has resulted in the listing of 12 salmon and steelhead populations in the basin as threatened or endangered under the Endangered Species Act. Once a species is listed as threatened or endangered, the act requires that efforts be taken to allow its recovery. Eleven federal agencies are involved with salmon and steelhead recovery efforts in the Columbia River Basin. The National Marine Fisheries Service (NMFS), as the lead agency, is responsible for preparing a recovery plan and consulting with the other federal agencies on their planned actions. The 11 federal agencies estimate expenditures of $1.8 billion from fiscal year 1982 through fiscal year 1996 and $1.5 billion from fiscal year 1997 through fiscal year 2001 on efforts specifically designed to recover Columbia River Basin salmon and steelhead. In addition to the $1.5 billion, the 11 federal agencies estimated that they expended $302 million in the last five fiscal years on modifications to mission-related projects that benefited, but were not specifically directed at, salmon and steelhead, such as erosion control to improve crop productivity and wildlife habitat, which also improves stream flows and reduces sedimentation in spawning habitat. Although federal agencies have undertaken many types of recovery actions, there is little conclusive evidence to quantify the extent of their efforts on returning fish populations. Recovery actions taken include projects, such as constructing fish passage facilities at dams; research studies, such as determining the presence or absence of toxic substances that cause diseases in fish; monitoring actions, such as surveying spawning grounds; and other activities, such as consultations required by the act.

Book excerpt: "PacifCorp Energy is applying to the National Oceanic and Atmospheric Administration's National Marine Fisheries Service (NMFS) for an incidental take permit (ITP) under Endangered Species Act Section 10(a)(1)(B) for a 10-year period authorizing the incidental take of Southern Oregon/Northern California Coast Evolutionary Significant Unit of coho salmon (Oncorhynchus kisutch), which is listed as threatened under the Endangered Species Act. The ITP would require implementation of a Habitat Conservation Plan with measures to monitor, mitigate, and minimize effects of PacifiCorp's Klamath Hydroelectric Project on these listed coho salmon for this period. Two alternatives were analyzed in this EA: issuance by NMFS of an ITP for listed Southern Oregon/Northern California Coast Evolutionary Significant Unit Coho salmon (Oncorhynchus kisutch) and the associated implementation of minimization and mitigation measures for coho salmon that would be implemented under an approved HCP (proposed action), or NMFS not issuing an ITP to PacifiCorp (no action alternative). The Proposed Action is likely to result in beneficial effects including improvements to salmonid populations and their habitat in the basin, potential for expanded prey base for fish-eating birds along the Klamath River mainstem, and improvements to employment opportunities for tribal and non-tribal workers in the basin. No significant adverse impacts to the human environment are expected as a result of the proposed action. The No Action alternative would in general not change the effects from those under current conditions, but continued degraded conditions in the Klamath River mainstem would occur with no mitigating actions taken to improve these degraded conditions. The preferred alternative for this EA is the proposed action"--Cover letter summary.
