The Geochemistry of Natural Waters
Author: James I. DreverPublisher:
ISBN:
Category : Juvenile Nonfiction

Pages : 458
Book Description
An examination of both theoretical and practical approaches to the geochemistry of natural waters with a more tightly focused emphasis on fresh-water environments. The third edition focuses more on environmental issues than the previous edition, reflecting the importance on environmental geochemistry as a result of increased environmental awareness and regulatory requirements. Prepares readers to interpret the probable cause of a particular water composition and to predict the probable water chemistry in those situations where data do not exist.

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
The U.S. Department of the Interior's Bureau of Land Management (BLM), Fish and Wildlife Service, and National Park Service, and the U.S. Department of Agriculture's Forest Service manage about 628 million acres of public land, mostly in the 11 western states and Alaska. Under the Federal Land Transaction Facilitation Act (FLTFA), revenue raised from selling BLM lands is available to the agencies, primarily to acquire non-federal land within the boundaries of land they already own -- known as in-holdings, which can create significant land management problems. To acquire land, the agencies can nominate parcels under state-level interagency agreements or the Secretaries can use their discretion to initiate acquisitions. FLTFA expires in 2010. The author was asked to determine (1)FLTFA revenue generated, (2)challenges to future sales, (3)FLTFA expenditures, and (4)challenges to future acquisitions. This is an edited and indexed edition.
