Effects of Forest Thinning Treatments on Fire Behavior


Book Description

One of the goals of restoration in southwestern ponderosa pine ecosystems is to reduce the risk of unnaturally severe wildfires. Many factors influence fire behavior including drought, topography, insect infestation, and weather but fuels are the only factor that people can realistically manage. This publication summarizes what is known about restoration treatment effects on fire behavior in ponderosa pine forests, and suggests treatment options that can alter future fire behavior.




Guide to Fuel Treatments in Dry Forests of the Western United States


Book Description

The Fire and Fuels Extension of the Forest Vegetation Simulator (FFE-FVS) was used to calulate the immediate effects of treatments on surface fuels, fire hazard, potential fire behavior, and forest structure for respresentative dry forest stands in the Western United States. Treatments considered included pile and burn and prescribed fire.




Forest Dreams, Forest Nightmares


Book Description

Across the inland West, forests that once seemed like paradise have turned into an ecological nightmare. Fires, insect epidemics, and disease now threaten millions of acres of once-bountiful forests. Yet no one can agree what went wrong. Was it too much management—or not enough—that forced the forests of the inland West to the verge of collapse? Is the solution more logging, or no logging at all? In this gripping work of scientific and historical detection, Nancy Langston unravels the disturbing history of what went wrong with the western forests, despite the best intentions of those involved. Focusing on the Blue Mountains of northeastern Oregon and southeastern Washington, she explores how the complex landscapes that so impressed settlers in the nineteenth century became an ecological disaster in the late twentieth. Federal foresters, intent on using their scientific training to stop exploitation and waste, suppressed light fires in the ponderosa pinelands. Hoping to save the forests, they could not foresee that their policies would instead destroy what they loved. When light fires were kept out, a series of ecological changes began. Firs grew thickly in forests once dominated by ponderosa pines, and when droughts hit, those firs succumbed to insects, diseases, and eventually catastrophic fires. Nancy Langston combines remarkable skills as both scientist and writer of history to tell this story. Her ability to understand and bring to life the complex biological processes of the forest is matched by her grasp of the human forces at work—from Indians, white settlers, missionaries, fur trappers, cattle ranchers, sheep herders, and railroad builders to timber industry and federal forestry managers. The book will be of interest to a wide audience of environmentalists, historians, ecologists, foresters, ranchers, and loggers—and all people who want to understand the changing lands of the West.




First Order Fire Effects Model


Book Description

A First Order Fire Effects Model (FOFEM) was developed to predict the direct consequences of prescribed fire and wildfire. FOFEM computes duff and woody fuel consumption, smoke production, and fire-caused tree mortality for most forest and rangeland types in the United States. The model is available as a computer program for PC or Data General computer.

Introduction to Prescribed Fire in Southern Ecosystems


Book Description

Prescribed burning is an important tool throughout Southern forests, grasslands, and croplands. The need to control fire became evident to allow forests to regenerate. This manual is intended to help resource managers to plan and execute prescribed burns in Southern forests and grasslands. A new appreciation and interest has developed in recent years for using prescribed fire in grasslands, especially hardwood forests, and on steep mountain slopes. Proper planning and execution of prescribed fires are necessary to reduce detrimental effects, such as the impacts on air and downstream water quality.

Biogeochemistry


Book Description

For the past 4 billion years, the chemistry of the Earth's surface, where all life exists, has changed remarkably. Historically, these changes have occurred slowly enough to allow life to adapt and evolve. In more recent times, the chemistry of the Earth is being altered at a staggering rate, fueled by industrialization and an ever-growing human population. Human activities, from the rapid consumption of resources to the destruction of the rainforests and the expansion of smog-covered cities, are all leading to rapid changes in the basic chemistry of the Earth. The Third Edition of Biogeochemistry considers the effects of life on the Earth's chemistry on a global level. This expansive text employs current technology to help students extrapolate small-scale examples to the global level, and also discusses the instrumentation being used by NASA and its role in studies of global change. With the Earth's changing chemistry as the focus, this text pulls together the many disparate fields that are encompassed by the broad reach of biogeochemistry. With extensive cross-referencing of chapters, figures, and tables, and an interdisciplinary coverage of the topic at hand, this text will provide an excellent framework for courses examining global change and environmental chemistry, and will also be a useful self-study guide. Emphasizes the effects of life on the basic chemistry of the atmosphere, the soils, and seawaters of the EarthCalculates and compares the effects of industrial emissions, land clearing, agriculture, and rising population on Earth's chemistrySynthesizes the global cycles of carbon, nitrogen, phosphorous, and sulfur, and suggests the best current budgets for atmospheric gases such as ammonia, nitrous oxide, dimethyl sulfide, and carbonyl sulfideIncludes an extensive review and up-to-date synthesis of the current literature on the Earth's biogeochemistry.




The Landscape Ecology of Fire


Book Description

Global warming is expected to change fire regimes, likely increasing the severity and extent of wildfires in many ecosystems around the world. What will be the landscape-scale effects of these altered fire regimes? Within what theoretical contexts can we accurately assess these effects? We explore the possible effects of altered fire regimes on landscape patch dynamics, dominant species (tree, shrub, or herbaceous) and succession, sensitive and invasive plant and animal species and communities, and ecosystem function. Ultimately, we must consider the human dimension: what are the policy and management implications of increased fire disturbance, and what are the implications for human communities?
