Book excerpt: This report describes the evidence for invasion of Pacific Northwest streams by Atlantic salmon (Salmo salar) that have escaped from marine salmon farms, and assesses the potential impact of farmed salmon invasion on native fishes inhabiting streams on National Forest System lands. The current risk to streams on National Forest lands in the Pacific Northwest from Atlantic salmon invasions appears to be low and is limited to a few areas in northwest Washington and southeast Alaska. However, long-term risks may be substantial if fish continue to escape from marine rearing pens or freshwater hatcheries. The two greatest threats appear to be that (1) Atlantic salmon could transmit a serious disease or parasite to native fishes, and (2) escaped salmon could eventually adapt to local conditions, leading to self-sustaining populations. If Atlantic salmon populations are eventually established, this species preference for swiftly flowing stream habitats could facilitate competition with currently at-risk species such as steelhead (Oncorhynchus mykiss). This could result in a pattern of expansion similar to that observed in other nonnative aquatic plants and animals, in which a prolonged early colonization period is followed by a rapid phase of exponential growth as breeding populations adapt to local conditions.

Book Synopsis The Rights of Indigenous Peoples in Marine Areas by : Stephen Allen
Download or read book The Rights of Indigenous Peoples in Marine Areas written by Stephen Allen and published by Bloomsbury Publishing. This book was released on 2019-09-19 with total page 565 pages. Available in PDF, EPUB and Kindle. Book excerpt: The question of what rights might be afforded to Indigenous peoples has preoccupied the municipal legal systems of settler states since the earliest colonial encounters. As a result of sustained institutional initiatives, many national legal regimes and the international legal order accept that Indigenous peoples possess an extensive array of legal rights. However, despite this development, claims advanced by Indigenous peoples relating to rights to marine spaces have been largely opposed. This book offers the first sustained study of these rights and their reception within modern legal systems. Taking a three-part approach, it looks firstly at the international aspects of Indigenous entitlements in marine spaces. It then goes on to explore specific country examples, before looking at some interdisciplinary themes of crucial importance to the question of the recognition of the rights of Indigenous peoples in marine settings. Drawing on the expertise of leading scholars, this is a rigorous and long-overdue exploration of a significant gap in the literature.

Available in PDF, EPUB and Kindle. Book excerpt: The importance of salmon to the Pacific Northwestâ€"economic, recreational, symbolicâ€"is enormous. Generations ago, salmon were abundant from central California through Idaho, Oregon, and Washington to British Columbia and Alaska. Now they have disappeared from about 40 percent of their historical range. The decline in salmon numbers has been lamented for at least 100 years, but the issue has become more widespread and acute recently. The Endangered Species Act has been invoked, federal laws have been passed, and lawsuits have been filed. More than $1 billion has been spent to improve salmon runsâ€"and still the populations decline. In this new volume a committee with diverse expertise explores the complications and conflicts surrounding the salmon problemâ€"starting with available data on the status of salmon populations and an illustrative case study from Washington state's Willapa Bay. The book offers specific recommendations for salmon rehabilitation that take into account the key role played by genetic variability in salmon survival and the urgent need for habitat protection and management of fishing. The committee presents a comprehensive discussion of the salmon problem, with a wealth of informative graphs and charts and the right amount of historical perspective to clarify today's issues, including: Salmon biology and geographyâ€"their life's journey from fresh waters to the sea and back again to spawn, and their interaction with ecosystems along the way. The impacts of human activitiesâ€"grazing, damming, timber, agriculture, and population and economic growth. Included is a case study of Washington state's Elwha River dam removal project. Values, attitudes, and the conflicting desires for short-term economic gain and long-term environmental health. The committee traces the roots of the salmon problem to the extractive philosophy characterizing management of land and water in the West. The impact of hatcheries, which were introduced to build fish stocks but which have actually harmed the genetic variability that wild stocks need to survive. This book offers something for everyone with an interest in the salmon issueâ€"policymakers and regulators in the United States and Canada; environmental scientists; environmental advocates; natural resource managers; commercial, tribal, and recreational fishers; and concerned residents of the Pacific Northwest.
Download or read book A Common Fate written by Joseph Cone and published by Macmillan + ORM. This book was released on 2014-10-28 with total page 443 pages. Available in PDF, EPUB and Kindle. Book excerpt: Though life on earth is the history of dynamic interactions between living things and their surroundings, certain powerful groups would have us believe that nature exists only for our convenience. One consequence of such thinking is the apparent fate of the Pacific salmon--a key resource and preeminent symbol of America's wildlife--which is today threatened with extinction. Drawing on abundant data from natural science, Pacific coast culture, and a long association with key individuals on all sides of the issue, Joseph Cone's A Common Fate employs a clear narrative voice to tell the human and natural history of an environmental crisis in its final chapter. As inevitable as the November rains, countless millions of wild salmon returned from the ocean to spawn in the streams of their birth. In the wake of an orgy of dam building and habitat destruction, the salmon's majestic abundance has been reduced to a fleeting shadow. Neglect is the word the author uses to describe more recent losses, "by exactly the ones--state and federal fish managers--who should have acted." To signal a new awareness that action is needed, scientists charged with restocking the Columbia River Basin are receiving significant support, while ordinary citizens are beginning to recognize the relationship between cheap power and the absences of chinook, coho, sockeye, and other species from the coasts of Oregon and Washington and from Idaho's Snake River. As desperate as the salmon's future appears, the book is not an elegy for a lost resource. Instead, it bears witness to hope. In addition to concrete plans for the wild salmon's renewal, the reader will hear a growing chorus of informed individuals of differing values and beliefs who recognize that our fate is inextricably bound to the salmon's; for many it is a new understanding.

Book Synopsis Physical Consequences of Large Organic Debris in Pacific Northwest Streams by : Frederick John Swanson
Download or read book Physical Consequences of Large Organic Debris in Pacific Northwest Streams written by Frederick John Swanson and published by . This book was released on 1978 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large organic debris in streams controls the distribution of aquatic habitats, the routing of sediment through stream systems, and the stability of streambed and banks. Management activities directly alter debris loading by addition or removal of material and indirectly by increasing the probability of debris torrents and removing standing streamside trees. We propose that by this combination of factors the character of small and intermediate-sized streams in steep forested terrain of the Pacific Northwest is being substantially altered by forest practices.
