Book excerpt: Abstract: Habitat is now the basis of most impact assessments and resource inventories, and it is the basis of many species management plans, mitigation planning, and environmental regulation. Habitats are relatively stable through time, easily defined in intuitive physical terms, and provide a tangible resource for negotiations and decision making. Numerous and varied methods of analyzing and reporting habitat conditions have been developed by federal, state, provincial, and private agencies. Habitat assessment approaches vary greatly among regions of the continent. The great variability in methods and an unusually wide range of practices have impeded the ability of agencies to share and synthesize information. A diversity of methods is desirable in the initial stages of a rapidly developing field, but enough time has passed to assess the state-of-knowledge and identify the best of the currently used methods and techniques. This manual is intended to provide fisheries biologists with a limited set of techniques for obtaining aquatic habitat data. The manual also describes the range of information collected and used in agency habitat analyses. Agencies planning habitat programs should review the synthesis of established and documented methods being used in North America (Appendix 1) and the planning recommendations in Chapter 2. Then, the remaining chapters should be reviewed to determine what types of habitat data should be included in the agency's program.
Download or read book Selection and Use of Indicators to Measure the Habitat Status of Wild Pacific Salmon written by Pacific Fisheries Resource Conservation Council and published by . This book was released on 2006 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: A key component of the Wild Pacific Salmon Policy is the conservation & stewardship of habitat for wild Pacific salmon. To focus & support habitat conservation & stewardship efforts, a suite of indicators at a range of scales is needed. This report represents a consolidation of a background information review & workshop project conducted to provide an overview of the state of habitat indicator development for wild Pacific salmon and to propose candidate indicators. After an introduction on the Wild Pacific Salmon Policy and the project study approach, chapter 2 presents an overview of Pacific salmon life history stages, habitat utilization, and relationships between salmon production & habitat characteristics. Chapter 3 summarizes previous activities related to development of salmon habitat indicators and frameworks for indicator selection. Chapter 4 contains a table of candidate indicators of habitat status. Chapter 5 lists data sources in British Columbia to support the candidate indicators. Chapter 6 briefly discusses several watershed-based programs related to wild Pacific salmon habitat & indicators. Chapter 7 is a summary of the salmon habitat indicator workshop findings; the full workshop report is appended. The final chapter makes recommendations for identifying a suite of habitat indicators with a view to optimizing the potential for successful implementation. Other appendices include a detailed preliminary analysis of the candidate indicators.

This book was released on 2005 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document reviews existing and proposed protocols used to monitor stream ecosystem conditions and responses to land management activities in the Pacific Northwest. Because of recent work aimed at improving the utility of habitat survey and fish abundance assessment methods, this review focuses on current (since 1993) monitoring efforts that assess stream habitat conditions and juvenile fish use. It does not focus on protocols specifically intended to monitor trends in fish populations for salmon recovery efforts, other fish life-history stages (e.g., salmonid smolt monitoring or spawner surveys), or approaches designed to monitor water quality or sources of pollution. We provide an overview of agency monitoring protocols, adaptive management, and types of monitoring, and briefly review the core habitat characteristics thought to be most sensitive to forest management practices. Finally, we summarize a selection of protocols in use in the Pacific Northwest in light of those core habitat characteristics.

Download or read book Physical Processes in the Coastal Zone written by Arthur P. Cracknell and published by CRC Press. This book was released on 1989-01-01 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: As people come to realize the importance of the environmental impact of human activities, the study of the coastal zone has become increasingly important. In addition, new environmental legislation at regional, national, and international levels will doubtless highlight the importance of a fuller understanding of the coastal areas. Together, these factors have led to substantial new requirements for the acquisition and monitoring of relevant environmental information and for a fuller understanding of the processes at work-work for which the use of remote sensing techniques is essential. To meet the requirements of this emerging discipline, Physical Processes in the Coastal Zone: Computer Modelling and Remote Sensing integrates basic physical processes with extensive information from remote sensing systems such as those on aircraft and spacecraft. It covers the physical processes that occur in the coastal zone, an area in which 60% of the world's population live. Written by international experts, the text provides a comprehensive, graduate-level introduction and overview that is suitable both for those entering the field and for those already working within it.

Available in PDF, EPUB and Kindle. Book excerpt: Procedures now exist to quantify the impacts of physical changes on productive capacity of fish habitat. These procedures allow the evaluation of pre- and post-development scenarios, including any compensatory measures. This report applies these procedures to two case studies consisting of the construction of a 150-metre long headland in Hamilton Harbour and the construction of marina breakwaters in the Bronte Outer Harbour, Lake Ontario. The investigations focused on evaluating the indirectly modified areas, or those affected by changes to wave and current patterns caused by the presence of the new development. Specific impacts examined include changes to surficial substrate and depth, changes to macrophyte coverage, changes to wave conditions, and the relationship between physical processes and macrophyte growth. A new criterion for limiting local wave conditions associated with the survival of macrophytes is proposed and recommendations are made to refine and substantiate such a criterion.
Download or read book Effects of Trawling and Dredging on Seafloor Habitat written by National Research Council and published by National Academies Press. This book was released on 2002-08-09 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concerns over the potential ecological effects of fishing have increased with the expansion of fisheries throughout the marine waters of the United States. Effects of Trawling and Dredging on Seafloor Habitat describes how assessment of fishing impacts depends on gear type, number and location of bottom tows, and the physical and biological characteristics of seafloor habitats. Many experimental studies have documented acute, gear-specific effects of trawling and dredging on various types of habitat. These studies indicate that low mobility, long-lived species are more vulnerable to towed fishing gear than short-lived species in areas where the seabed is often disturbed by natural phenomena. Trawling and dredging may also change the composition and productivity of fish communities dependent on seafloor habitats for food and refuge. The scale of these impacts depends on the level of fishing effort. This volume presents color maps of fishing effort for all regions with significant bottom trawl or dredge fisheries-the first time that such data has been assembled and analyzed for the entire nation.
