Available in PDF, EPUB and Kindle. Book excerpt: Sound decisions about the use and conservation of natural resources require high-quality, independent scientific information accessible to all who need it. Provision of such information, particularly on the status and trends of the nation's biological resources, is central to the mission of the U.S. Geological Survey's (USGS) Biological Resources Division, formerly the National Biological Service (NBS). This report, The Status and Trends of the Nation's Biological Resources, is a major contribution to meeting the nation's need for better information about our nation's living resources. This two-volume book provides the first large-scale assessment of the health of the nation's plants, animals, and ecosystems and is intended for use by managers, scientists, policy makers, and the general public. It synthesizes existing and new information about birds, mammals, fishes, plants, and other species and summarizes what is known about the status and trends of major U.S. ecosystems. The findings reported here offer valuable insight into both successes and failures in resource management and point the way to better management of biological resources in the future.

Download or read book Ecological Dynamics on Yellowstone s Northern Range written by National Research Council and published by National Academies Press. This book was released on 2002-02-01 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological Dynamics on Yellowstone's Northern Range discusses the complex management challenges in Yellowstone National Park. Controversy over the National Park Service's approach of "natural regulation" has heightened in recent years because of changes in vegetation and other ecosystem components in Yellowstone's northern range. Natural regulation minimizes human impacts, including management intervention by the National Park Service, on the park ecosystem. Many have attributed these changes to increased size of elk and other ungulate herds. This report examines the evidence that increased ungulate populations are responsible for the changes in vegetation and that the changes represent a major and serious change in the Yellowstone ecosystem. According to the authors, any human intervention to protect species such as the aspen and those that depend on them should be prudently localized rather than ecosystem-wide. An ecosystem-wide approach, such as reducing ungulate populations, could be more disruptive. The report concludes that although dramatic ecological change does not appear to be imminent, approaches to dealing with potential human-caused changes in the ecosystem, including those related to climate change, should be considered now. The need for research and public education is also compelling.
Download or read book A Biological Survey for the Nation written by National Research Council and published by National Academies Press. This book was released on 1993-02-01 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our country has long recognized the importance of its biological resources but we often lack sufficient scientific knowledge to make wise decisions. This realization has led to calls for new ways of providing this information, including the formation of a national biological survey. This volume discusses key issues and problems for which an improved assessment of the nation's biological resources is needed; the kinds of efforts in research and information management needed to create that assessment; and how government, private organizations, and individuals can work together to meet the needs identified. Policymakers, resource managers, public interest groups, and researchers will find this book useful as they participate in the national dialogue on this topic and take actions to implement the needed survey activities.
