Book Description
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.

Book Description
Early hunter/gatherer societies have traditionally been considered basically egalitarian in nature. This assumption, however, has been challenged by contemporary archaeological and anthropological research, which has demonstrated that many of these societies had complex social, economic, and political structures. This volume considers two British Columbia Native communities -- the Lillooet and Shuswap communities of Fountain and Pavilion - and traces their development into complex societies. The authors explore the relation between resource characteristics and hunter/gatherer adaptations and examine the use of fish, animal, and plant species, documenting their availability and the techniques used in their gathering, processing, and storing. The book also shows how cultural practices, such as raiding, potlatching, and stewardship of resources, can be explained from a cultural ecological point of view. An important contribution to the study of hunting and gathering cultures in the Northwest, this book is the most detailed examination of the subsistence base of a particular hunting and gathering group to date. Its exploration of the reasons why complex hunting and gathering societies emerge, as well as the ecological relationships between cultures and resources, will make an important contribution to the study of cultural ecology and contemporary archaeology.
