Recon?guring Disturbance, Succession, and Forest Management: The Science of Mount St. Helens When Mount St. Helens erupted on May 18, 1980, it did more than just recon?gure a large piece of Cascadian landscape. It also led to dramatic revisions in our perspectives on disturbances, secondary succession, and forestry practices. The Mount St. Helens landscape turned out to be a far more complex place than the "moonscape" that it initially appeared to be. Granted, a large area was literally scoured and sterilized, and that vast expanse of newly formed rock, mud?ows, and avalanche debris up and...

This volume applies ecological principles and guidelines to understand past and current land use and land management; and more importantly, endeavors to promote more ecologically sound approaches to future land use and management decisions. The volume incorporates case studies from a wide variety of disciplines and perspectives. The case studies explore past and current land use decisions, on both public and private lands, and include practical approaches and tools for land-use decision-making. Perhaps the most important feature of the book is the linking of ecological theory and principle...

This book was developed from a workshop on the "Effective Use of Ecological Modeling in Management," held in Oak Ridge, Tennessee, on October 23-26, 2000. The workshop was sponsored by the Department of Defense's (DoD's) Strategic Environmental Research and Development Program (SERDP), the Army Research Of?ce, and the Engineering Research and Development Center of the Corps of Engineers as well as by the U. S. Department of Agriculture (USDA) Forest Service. It was hosted by the Department of Energy's (DOE's) Oak Ridge National Laboratory (ORNL). The organizing committee for the workshop...

Environmental decision making is, like politics, mostly local. In fact, making decisions about the environment at the subnationallevel-in state, regional, and local jurisdictions-is a lot like politics. For resolving environ mental issues demands, but often resists, a balance between deeply held feelings and stark confrontations among opposing views. This volume describes tools that should make the decision maker's lot a bit more tolerable. The authors would be the last to suggest that these decision-aiding tools will somehow bring a benign order to issues that reach to people's fundamental...

Since 1985, scientists have been documenting a hypoxic zone in the Gulf of Mexico each year. The hypoxic zone, an area of low dissolved oxygen that cannot s- port marine life, generally manifests itself in the spring. Since marine species either die or ee the hypoxic zone, the spread of hypoxia reduces the available habitat for marine species, which are important for the ecosystem as well as commercial and recreational shing in the Gulf. Since 2001, the hypoxic zone has averaged 2 1 16,500 km during its peak summer months, an area slightly larger than the state 2 2 of Connecticut, and ranged...

Environmental decisions are made every day in manufacturing plants, city council meetings, and corporate board rooms. This book is unique in identifying and presenting tools to environmental decision-makers to help them improve the quality and clarity of this vital process. The tools described in this book range from software to policy approaches, and from environmental databases to focus groups. Tools to Aid Environmental Decision Making will be of value to decision makers and their staffs, environmental managers, and students in environmental risk, policy, economics and law.

Roger C. Dahlman Environmental Sciences Division U.S. Department of Energy Washington, D.C. The potential for humans to alter Earth's atmosphere has been recognized since the end of the 19th century when Arrhenius estimated that a doubling of atmospheric carbon dioxide could alter the atmospheric radiation balance and raise average global temperature. Today, atmospheric CO concentrations play an important part in the 2 climate-change debate. Sources and sinks of CO associated with land use can be 2 significant determinants of the rate and magnitude of atmospheric CO change. 2 Combustion of...
