This book was released on 2023-01-17 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our national parks are more than mere recreational destinations. They are repositories of the nation's biological diversity and contain some of the last ecosystem remnants needed as standards to set reasonable goals for sustainable development throughout the land. Nevertheless, public pressure for recreation has largely precluded adequate research and resource monitoring in national parks, and ignorance of ecosystem structure and function in parks has led to costly mistakes--such as predator control and fire suppression--that continue to threaten parks today. This volume demonstrates the value of ecological knowledge in protecting parks and shows how modest investments in knowledge of park ecosystems can pay handsome dividends. Science and Ecosystem Management in the National Parks presents twelve case studies of long-term research conducted in and around national parks that address major natural resource issues. These cases demonstrate how the use of longer time scales strongly influence our understanding of ecosystems and how interpretations of short-term patterns in nature often change when viewed in the context of long-term data sets. Most importantly, they show conclusively that scientific research significantly reduces uncertainty and improves resource management decisions. Chosen by scientists and senior park managers, the cases offer a broad range of topics, including: air quality at Grand Canyon; interaction between moose and wolf populations on Isle Royale; control of exotic species in Hawaiian parks; simulation of natural fire in the parks of the Sierra Nevada; and the impact of urban expansion on Saguaro National Monument. Because national parks are increasingly beset with conflicting views of their management, the need for knowledge of park ecosystems becomes even more critical--not only for the parks themselves, but for what they can tell us about survival in the rest of our world. This book demonstrates to policymakers and managers that decisions based on knowledge of ecosystems are more enduring and cost effective than decisions derived from uninformed consensus. It also provides scientists with models for designing research to meet threats to our most precious natural resources. "If we can learn to save the parks," observe Halvorson and Davis, "perhaps we can learn to save the world."

This book was released on 2012-12-06 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rocky Mountain National Park was established in 1915, one year before the creation of the National Park Service. The mandate of the National Park Service is to preserve and protect areas of exquisite beauty and cultural value for the benefit and enjoyment of future generations. National parks mean many things to many people, and, in often stirring words, a National Parks and Conservation Association report states the National Park System is a magnificent and uniquely American gift to the American people and the world. In the early years of the Service, park superintendents actively promoted and developed parks to accommodate visitors. Then, as now, parks represented a democratic ideal, that even the greatest treasures should be available to all. Seventy five years ago, however, park managers saw little need for active management of natural resources, unless it was to enhance visitors' experience. And few managers saw the need for a stable and independent research program on which to base management decisions. Thus began a legacy of erratic, often passive, resource management based more on politics and in-house studies than on validated scientific informa tion. The world is a different place than it was 75 years ago. Human population growth, changes in land use, and ever more sophisticated technology affect the very fabric of life on Earth. As local-, regional-, and global-scale changes occur from human tampering with the environment, the integrity of natural ecosystems is threatened worldwide.

Book excerpt: “An eclectic, enjoyable mix of literature reviews, personal experience and case studies, and practical advice from . . . leaders in their subdisciplines.” —Eleanor J. Sterling, Chief Conservation Scientist, Center for Biodiversity & Conservation, American Museum of Natural History With the US National Park Service over one hundred years old, parks and protected areas worldwide are under increasing threat from storms and fires of greater severity, plant and animal extinctions, the changing attitudes of a public that has become more urbanized, and the political pressures of narrow special interest groups. In the face of such rapid environmental and cultural changes, Science, Conservation, and National Parks gathers a group of renowned scholars—including Edward O. Wilson, Jane Lubchenco, Thomas Dietz, and Monica Turner—who address these problems and in the hope of securing a future for protected areas that will push forward the frontiers of biological, physical, and social science in and for parks. Contributors provide answers to a number of key conservation questions, such as: How should stewardship address climate change, urban encroachment and pollution, and invasive species? How can society, especially youth, become more engaged with nature and parks? What are appropriate conservation objectives for parks in the Anthropocene? Charting a course for the parks of the next century, Science, Conservation, and National Parks catalyzes the continued evolution of US park conservation policy, and serves as an inspiration for parks, conservation, and management worldwide. “Offers a refreshing holistic treatment of the linkages and mutual dependencies between parks and science. Compelling.” —William B. Monahan, USDA Forest Service and formerly of the US National Park Service “This is a testament to what can be achieved by determined conservationists.” —Biodiversity and Conservation journal

Available in PDF, EPUB and Kindle. Book excerpt: Although the earth has been around for millions of years, humans have only been seriously interested in protecting and preserving the environment for less than 200 years and the terms conservationism and environmentalism are little more than 100 years old. The industrial revolution brought with it many benefits such as the production of coal, steel and cement, and mass produced chemicals and fertilizers; it also brought pollution, and shortly thereafter, a serious concern for the environment. This book presents the most up-to-date government information on various environmental topics. Critical Government Documents on the Environment presents official governmental positions on many of the leading environmental issues facing us today. All the material in this book is from published sources, including: Environmental Protection Agency Department of the Interior Department of Energy Department of Agriculture Department of Health and Human Services The White House National Aeronautics and Space Administration National Oceanic & Atmospheric Administration National Weather Service US Global Change Research Program US Geological Survey This book does not offer any new science but attempts to present important government information on various issues facing our environment. Areas covered include global warming and greenhouse gases, the Keystone Pipeline and mining, water, air and marine pollution, mining and renewable energy. It includes a timeline of important environmental events over the last 200 years and has an extensive glossary of environmental terms. About the Series: The Critical Documents Series looks at critical issues of our times. It provides non-partisan information with no spin about critical players, events, and information from and about Washington from as many sources as possible—from scientific journals and government reports to political manifestos and lobby group publications. It collects and distills the most important government documents on the issues covered so that you can get the information you need quickly and easily.
