The symposium "Pacific Salmon and Their Ecosystems: Status and Future Options',' and this book resulted from initial efforts in 1992 by Robert J. Naiman and Deanna J. Stouder to examine the problem of declining Pacific salmon (Oncorhynchus spp.). Our primary goal was to determine informational gaps. As we explored different scientific sources, state, provincial, and federal agencies, as well as non-profit and fishing organizations, we found that the information existed but was not being communicated across institutional and organizational boundaries. At this juncture, we decided to create a steering committee and plan a symposium to bring together researchers, managers, and resource users. The steering committee consisted of members from state and federal agencies, non-profit organizations, and private industry (see Acknowledgments for names and affiliations). In February 1993, we met at the University of Washington in Seattle to begin planning the symposium. The steering committee spent the next four months developing the conceptual framework for the symposium and the subsequent book. Our objectives were to accomplish the following: (1) assess changes in anadromous Pacific Northwest salmonid populations, (2) examine factors responsible for those changes, and (3) identify options available to society to restore Pacific salmon in the Northwest. The symposium on Pacific Salmon was held in Seattle, Washington, January 10-12, 1994. Four hundred and thirty-five people listened to oral presentations and examined more than forty posters over two and a half days. We made a deliberate attempt to draw in speakers and attendees from outside the Pacific Northwest.

Canada's Wild Salmon Policy (WSP) was released in June 2005 with a goal to restore and maintain healthy and diverse salmon populations and their habitats. Strategy 3, Action Step 3.1 aims to include ecosystem values in decision-making by proposing "ecosystem indicators" to monitor the status of freshwater and terrestrial ecosystems. The scientific basis for proposing ecosystem indicators within the WSP recognizes that Pacific salmon play an important role in marine, freshwater, and terrestrial ecosystems, including streams, lakes, riparian forests and wildlife food webs. Managers influence these ecosystems by considering changes in fisheries regulations (i.e., harvest levels) and artificial enhancement (e.g., hatcheries). Thus, the role of ecosystem indicators is to provide a measure of ecosystem responses to changes in spawner abundance, thereby helping managers understand how changes in their actions affect freshwater and terrestrial ecosystems. This work serves three functions: (1) provide a first attempt at developing ecosystem indicators for Strategy 3 of the Wild Salmon Policy; (2) recommend further development and refinement of ecosystem indicators; and (3) suggest next steps. To serve these functions, we reviewed the literature to develop a better understanding of the linkages among the five Pacific salmon species and freshwater / terrestrial ecosystems, and used our resulting summary on the "state of the science" to provide a scientific rationale for recommending ecosystem indicators and next steps.

The Behavior and Ecology of Pacific Salmon and Trout explains the patterns of mate choice, the competition for nest sites, and the fate of the salmon after their death. It describes the lives of offspring during the months they spend incubating in gravel, growing in fresh water, and migrating out to sea to mature. This thorough, up-to-date survey should be on the shelf of everyone with a professional or personal interest in Pacific salmon and trout. Written in a technically accurate but engaging style, it will appeal to a wide range of readers, including students, anglers, biologists, conservationists, legislators, and armchair naturalists.

Few subjects have generated as much emotional dialogue around conflicting scientific and policy agendas as the protection and management of Pacific salmon resources. In this major new work, esteemed fisheries expert Thomas Quinn distills from the vast scientific literature the essential information on the behavior and ecology of Pacific salmon, including steelhead and cutthroat trout. Unlike other books that examine only selected life stages, habitats, or species, this book--richly illustrated with beautiful photographs and original drawings--thoroughly covers the complete life cycle, emphasizing common themes and differences among the various species of salmon. Representing the range of species and geographic regions, Quinn includes examples from classic studies by pioneers of salmon biology and from the most current research to illustrate the important features of salmon life history and behavior and the complex physical, biological, and human factors that affect them. The Behavior and Ecology of Pacific Salmon and Trout introduces salmon and trout as a group, with a brief description of each species, and compares them to other fishes. The book then follows salmon on their amazing homeward migration from the open ocean, through the complex coastal waters, and upstream to the precise location where they were spawned years earlier. It explains the patterns of mate choice, the competition for nest sites, and the fate of the salmon after their death. It describes the lives of offspring during the months they spend incubating in gravel, growing in fresh water, and migrating out to sea to mature. Quinn emphasizes the importance of salmon to humans and to natural ecosystems and the need to integrate sound biology into conservation efforts. This thorough, up-to-date survey should be on the shelf of anyone with a professional or personal interest in Pacific salmon and trout. Written in a technically accurate but engaging style, it will appeal to a wide range of readers, including students, anglers, biologists, conservationists, legislators, and armchair naturalists.

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.

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 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 beliefswho recognize that our fate is inextricably bound to the salmon's; for many it is a new understanding.
