Download or read book Protecting Visibility in National Parks and Wilderness Areas written by National Research Council and published by National Academies Press. This book was released on 1993-02-01 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scenic vistas in most U.S. parklands are diminished by haze that reduces contrast, washes out colors, and renders distant landscape features indistinct or invisible. Protecting Visibility in National Parks and Wilderness Areas describes the current understanding of the nature and extent of haze in various regions of the United States. The book addresses the scientific and legal framework of efforts to protect and improve visibility, as well as methods for assessing the relative importance of anthropogenic emission sources that contribute to haze in national parks and for considering various alternative source control measures. The volume provides guidance on how to make progress toward the national goal of correcting and preventing visibility impairment due to human activities affecting large national parks and wilderness areas.

Download or read book Ecosystem Management for Parks and Wilderness written by James K. Agee and published by University of Washington Press. This book was released on 1988 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: The need for cooperation among government agencies as well as an interdisciplinary approach to the increasingly challenging and complicated problem of managing park and wilderness areas prompted the University of Washington College of Forest Resources, the National Park Service, and the Forest Service to sponsor an ecosystem management workshop for scientists, planners, and managers. To develop an improved conceptual approach to managing change in ecosystems crossing natural and political boundaries, the workshop focused on defining terms, uncovering areas of misunderstanding and barriers to cooperation, and developing methods to determine the most important problems and issues. Three needs emerged from the prioritization process: a precise definition of the management objectives for park and wilderness lands and how to integrate them with objectives for surrounding lands, nationally as well as site-specific; more information about physical, biological, and social components of park and wilderness ecosystems from both sides of political boundaries; and key indicators of ecosystem condition as well as methods for evaluating management effectiveness. All of these common themes point to a need for more precise direction in management goal setting and more accurate assessment of progress toward goals. The book includes an introductory chapter by the editors and summary in which they outline a direction for ecosystem management in the next critical decades. The other chapters by individual contributors include studies on laws governing park and wilderness lands, paleoecological records that reveal the historic effects of climatic variations on vegetation change, succession and natural disturbance in relation to the problems of what can and should be preserved, managing ecosystems for large populations of vertebrates, the management of large carnivores, effects of air pollution, lake acidification, human ecology and environmental management, the role of economics, cooperation in ecosystem management, and management challenges in Yellowstone National Park.

Available in PDF, EPUB and Kindle.

These contaminants impact sensitive natural resources in wilderness, including the national parks. The system of national parks in the United States is among our greatest assets. This book provides a compilation and synthesis of current scientific understanding regarding the causes and effects of these pollutants within national park lands. It describes pollutant emissions, deposition, and exposures; it identifies the critical (tipping point) loads of pollutant deposition at which adverse impacts are manifested.
