Wild Salmonids In The Urbanizing Pacific Northwest

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.​

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.

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.

An introduction to the problem of salmon extinction is followed by historical and contemporary views on issues such as Columbia River fisheries, artificial propagation of salmon, and fishing regulations. Subsequent sections address the problems caused by various technologies and bureaucratic actions; Native American involvement in the issue, both historical and contemporary; and what should be done to prevent wild salmon extinction. c.

River Science is a rapidly developing interdisciplinary field at the interface of the natural sciences, engineering and socio-political sciences. It recognises that the sustainable management of contemporary rivers will increasingly require new ways of characterising them to enable engagement with the diverse range of stakeholders. This volume represents the outcome of research by many of the authors and their colleagues over the last 40 years and demonstrates the integral role that River Science now plays in underpinning our understanding of the functioning of natural ecosystems, and how societal demands and historic changes have affected these systems. The book will inform academics, policy makers and society in general of the benefits of healthy functioning riverine systems, and will increase awareness of the wide range of ecosystem goods and services they provide.

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.

This handbook provides a state-of-the-art, comprehensive overview of the expanding field of urban biodiversity. The field of urban biodiversity has emerged from within the broad discipline of urban ecology in the past two decades and is now a significant field in its own right. In view of this, the Routledge Handbook of Urban Biodiversity presents a thorough treatment of this field detailing the history of urban biodiversity, theoretical foundations, current state of knowledge, and application of that knowledge. The handbook is split into four parts: Part I: Setting the Stage for Urban Biodiversity Research and Practice Part II: Foundational Concepts and Theory in Urban Biodiversity Research Part III: Population and Community Ecology of Key Urban Taxa Part IV: Urban Biodiversity Practice: Management, Planning, and Design for Healthy Communities This volume contains interdisciplinary and global contributions from established and early career academics as well as professionals and practitioners, addressing two key fields in urban biodiversity: fundamental research focused on answering questions about the mechanisms explaining the distribution of species among and within cities; and applied research and work by practitioners to address concerns about urban biodiversity conservation, restoration, planning, design, and public involvement. This handbook is essential reading for students, academics, and professionals interested and working in the fields of urban biodiversity, ecology, nature conservation, urban planning, and landscape architecture.
