Available in PDF, EPUB and Kindle. Book excerpt: As the vast expanses of natural forests and the great populations of salmonids are harvested to support a rapidly expanding human population, the need to understand streams as ecological systems and to manage them effectively becomes increasingly urgent. The unfortunate legacy of such natural resource exploitation is well documented. For several decades the Pacific coastal ecoregion of North America has served as a natural laboratory for scientific and managerial advancements in stream ecology, and much has been learned about how to better integrate ecological processes and characteristics with a human-dominated environment. These in sightful but hard-learned ecological and social lessons are the subject of this book. Integrating land and rivers as interactive components of ecosystems and watersheds has provided the ecological sciences with impor tant theoretical foundations. Even though scientific disciplines have begun to integrate land-based processes with streams and rivers, the institutions and processes charged with managing these systems have not done so successfully. As a result, many of the watersheds of the Pacific coastal ecoregion no longer support natural settings for environmental processes or the valuable natural resources those processes create. An important role for scientists, educators, and decision makers is to make the integration between ecology and con sumptive uses more widely understood, as well as useful for effective management.

Download or read book Wild Salmonids in the Urbanizing Pacific Northwest written by J. Alan Yeakley and published by Springer Science & Business Media. This book was released on 2013-11-20 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wild salmon, trout, char, grayling, and whitefish (collectively salmonids) have been a significant local food and cultural resource for Pacific Northwest peoples for millennia. The location, size, and distribution of urban areas along streams, rivers, estuaries, and coasts directly and indirectly alter and degrade wild salmonid populations and their habitats. Although urban and exurban areas typically cover a smaller fraction of the landscape than other land uses combined, they have profound consequences for local ecosystems, aquatic and terrestrial populations, and water quality and quantity.
Download or read book Riparian and Aquatic Habitats of the Pacific Northwest and Southeast Alaska written by Fred H. Everest and published by . This book was released on 2007 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Management of riparian habitats is controversial because land use policies have historically emphasized economic values (e.g., timber production) at the expense of ecological and social values. Attempting to manage these valuable resources to attain the greatest combination of benefits has created a long-term controversy that continues to the present. Our analysis indicates that at mid to large spatial scales, healthy riparian ecosystems and land management activities are not mutually exclusive, but the degree of compatibility is determined by policy decisions based on competing demands and pressing timelines as well as available scientific knowledge. Current management schemes on federal lands in the Pacific Northwest and Alaska are appropriately addressing large spatial scales and incorporating the principles of disturbance ecology. We found no scientific evidence that either the default prescriptions or the options for watershed analysis in the Northwest Forest Plan and Tongass Land Management Plan provide more protection than necessary to meet stated riparian management goals. We believe that additional alternative riparian management strategies could be implemented and evaluated in concert to shorten the time needed to realize effective strategies that fully meet riparian management goals.
Download or read book Wetland and Stream Rapid Assessments written by John Dorney and published by Academic Press. This book was released on 2018-08-07 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wetland and Stream Rapid Assessments: Development, Validation, and Application describes the scientific and environmental policy background for rapid wetland and stream assessments, how such assessment methods are developed and statistically verified, and how they can be used in environmental decision-making—including wetland and stream permitting. In addition, it provides several case studies of method development and use in various parts of the world. Readers will find guidance on developing and testing such methods, along with examples of how these methods have been used in various programs across North America. Rapid wetland and stream functional assessments are becoming frequently used methods in federal, state and local environmental permitting programs in North America. Many governments are interested in developing new methods or improving existing methods for their own jurisdictions. This book provides an ideal guide to these initiatives. - Offers guidance for the use and evaluation of rapid assessments to developers and users of these methods, as well as students of wetland and stream quality - Contains contributions from sources who are successful in academia, industry and government, bringing credibility and relevance to the content - Includes a statistically-based approach to testing the validity of the rapid method, which is very important to the usefulness and defensibility of assessment methods

Available in PDF, EPUB and Kindle. Book excerpt: "The Salish Sea is a feast for the eyes, a high-quality publishing effort rich in glossy colour photos and fascinating biological information that is likely to surprise even someone well-versed in our marine waters." —The Vancouver Sun In stunning color photographs, and compelling stories, this keepsake book reveals the the Salish Sea, a unique ecosystem home to thousands of different species of mammals, birds, fish, reptiles, and macro-invertebrates. The Salish Sea region is an ecological jewel straddling the western border between Canada and the United States, connected to the Pacific Ocean primarily through the Strait of Juan de Fuca. There, lush and mossy old-growth forests meet waters with dazzlingly-colored anemones and majestic orcas. This is the first book of its kind to describe the Salish Sea, whose name was not even officially recognized until 2008. One of the world’s largest inland seas, the Salish Sea contains 6,535 square miles of sea surface area and 4,642 miles of coastline. This fascinating visual journey through the Salish Sea combines a scientist’s inquiring mind, dazzling full-color photographs, and a lively narrative of fascinating stories, all of which impart a sense of connection with this intricate marine ecosystem and the life that it sustains.

This book was released on 2004 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: An Aquatic and Riparian Effectiveness Monitoring Plan (AREMP) for the Northwest Forest Plan is intended to characterize the ecological condition of watersheds and aquatic ecosystems. So to determine the effectiveness of the Northwest Forest Plan to meet relevant objectives, this report presents the conceptual foundation of options for use in pilot testing and implementing an effectiveness monitoring program for aquatic and riparian systems. The base program would evaluate status and trends of watershed, stream, and riparian conditions by using decision-support models. Although the focus of AREMP is on characterizing ecosystem status and trend, implementing it will also supply information that will be useful in determining causal relations to help explain those trends.
