Available in PDF, EPUB and Kindle. Book excerpt: Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

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.

This book was released on 2005-01-24 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: The tension between wildlife protection under the Endangered Species Act and water management in the Platte River Basin has existed for more than 25 years. The Platte River provides important habitat for migratory and breeding birds, including three endangered or threatened species: the whooping crane, the northern Great Plains population of the piping plover, and the interior least tern. The leading factors attributed to the decline of the cranes are historical overhunting and widespread habitat destruction and, for the plovers and terns, human interference during nesting and the loss of riverine nesting sites in open sandy areas that have been replaced with woodlands, sand and gravel mines, housing, and roadways. Extensive damming has disrupted passage of the endangered pallid sturgeon and resulted in less suitable habitat conditions such as cooler stream flows, less turbid waters, and inconsistent flow regimes. Commercial harvesting, now illegal, also contributed to the decline of the sturgeon. Endangered and Threatened Species of the Platte River addresses the habitat requirements for these federally protected species. The book further examines the scientific aspects of the U.S. Fish and Wildlife Service's instream-flow recommendations and habitat suitability guidelines and assesses the science concerning the connections among the physical systems of the river as they relate to species' habitats.

Available in PDF, EPUB and Kindle. Book excerpt: This volume is the second in the UK-originated series, Antony Orme and Andrew Goudie, eds., Physical Environments of the World, following The Physical Geography of Africa (Feb. 1996). The aim of the series is to present a "relatively durable statement of physical conditions on the continents" written by a team of specialists. In common with the other volumes in the series the book is divided into three parts: (I) systematic coverage of the main components of the physical environment, (II) regional treatment based on the biome concept, and (III) human responses to the physical landscape. The book is intended to fill a void in recent geographic literature by providing an interpretive work that integrates knowledge "across the environment" while placing recent discoveries in a human context. Using tectonism as an example, Orme writes that this topic "will not be viewed as an end in itself, but as a series of processes and crustal adjustments that have significant implication for climate change and plant and animal migrations." The contributing authors are among the most active and best in their fields in the United States and Canada.

Available in PDF, EPUB and Kindle. Book excerpt: The Missouri River Ecosystem: Exploring the Prospects for Recovery resulted from a study conducted at the request of the U.S. Environmental Protection Agency and the U.S. Army Corps of Engineers. The nation's longest river, the Missouri River and its floodplain ecosystem experienced substantial environmental and hydrologic changes during the twentieth century. The context of Missouri River dam and reservoir system management is marked by sharp differences between stakeholders regarding the river's proper management regime. The management agencies have been challenged to determine the appropriate balance between these competing interests. This Water Science and Technology Board report reviews the ecological state of the river and floodplain ecosystem, scientific research of the ecosystem, and the prospects for implementing an adaptive management approach, all with a view toward helping move beyond ongoing scientific and other differences. The report notes that continued ecological degradation of the ecosystem is certain unless some portion of pre-settlement river flows and processes were restored. The report also includes recommendations to enhance scientific knowledge through carefully planned and monitored river management actions and the enactment of a Missouri River Protection and Recovery Act.
