Download or read book Forest Fires written by Edward A. Johnson and published by Elsevier. This book was released on 2001-03-01 with total page 617 pages. Available in PDF, EPUB and Kindle. Book excerpt: Even before the myth of Prometheus, fire played a crucial ecological role around the world. Numerous plant communities depend on fire to generate species diversity in both time and space. Without fire such ecosystems would become sterile monocultures. Recent efforts to prohibit fire in fire dependent communities have contributed to more intense and more damaging fires. For these reasons, foresters, ecologists, land managers, geographers, and environmental scientists are interested in the behavior and ecological effects of fires. This book will be the first to focus on the chemistry and physics of fire as it relates to the ways in which fire behaves and the impacts it has on ecosystem function. Leading international contributors have been recruited by the editors to prepare a didactic text/reference that will appeal to both advanced students and practicing professionals.

This book was released on 2003 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The RAWS network and RAWS data-use systems are closely reviewed and summarized in this report. RAWS is an active program created by the many land-management agencies that share a common need for accurate and timely weather data from remote locations for vital operational and program decisions specific to wildland and prescribed fires. A RAWS measures basic observable weather parameters such as temperature, relative humidity, wind speed, wind direction, and precipitation as well as "fuel stick" temperature. Data from almost 1,900 stations deployed across the conterminous United States, Alaska, and Hawaii are now routinely used to calculate and forecast daily fire danger indices, components, and adjective ratings. Fire business applications include the National Fire Danger Rating System (NFDRS), fire behavior, and fire use. Findings point to the fact that although the RAWS program works and provides needed weather data in support of fire operations, there are inefficiencies and significant problem areas that require leadership attention at the National level."

Download or read book Field Guide Fire in Dry Eucalypt Forest written by JS Gould and published by CSIRO PUBLISHING. This book was released on 2008-08-12 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: An effective response to bushfires relies on accurate predictions of fire behaviour, particularly the rate of spread, intensity and ‘spotting’. This field guide has been developed to provide a systematic method for assessing fuel hazard and predicting potential fire behaviour in dry eucalypt forest. It will assist in making vital decisions that ensure the protection of fire crews and the community. This guide integrates Project Vesta research findings with the Victorian Overall Fuel Hazard Guide and is applicable to dry eucalypt forests throughout southern Australia. Fuel assessment is based on the hazard scoring system employed during Project Vesta which investigated the effects of fuel age and understorey vegetation structure on fire behaviour in these forests. Information provided in this guide can be used to: Define and identify different fuel layers and components of fuel structure and hazard; Determine the hazard score of surface and near-surface fuel layers and the height of the near-surface fuel for fire spread prediction; Determine elevated fuel height for flame height prediction; and determine surface fuel hazard score and bark hazard score for spotting distance prediction. The Field Guide provides tables to predict the potential rate of spread of a bushfire burning in dry eucalypt forest under summer conditions, and can also be used to predict flame height and maximum spotting distance. The guide also allows users to determine the moisture content of fine dead fuels throughout the day, and to account for the effect of slope on the rate of spread of a fire.

Download or read book The Photoload Sampling Technique written by Robert E. Keane and published by . This book was released on 2007 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fire managers need better estimates of fuel loading so they can more accurately predict the potential fire behavior and effects of alternative fuel and ecosystem restoration treatments. This report presents a new fuel sampling method, called the photoload sampling technique, to quickly and accurately estimate loadings for six common surface fuel components (1 hr, 10 hr, 100 hr, and 1000 hr downed dead woody, shrub, and herbaceous fuels). This technique involves visually comparing fuel conditions in the field with photoload sequences to estimate fuel loadings. Photoload sequences are a series of downward-looking and close-up oblique photographs depicting a sequence of graduated fuel loadings of synthetic fuelbeds for each of the six fuel components. This report contains a set of photoload sequences that describe the range of fuel component loadings for common forest conditions in the northern Rocky Mountains of Montana, USA to estimate fuel loading in the field. A companion publication (RMRS-RP-61CD) details the methods used to create the photoload sequences and presents a comprehensive evaluation of the technique.

Download or read book Project Vesta Fire in Dry Eucalypt Forest written by JS Gould and published by CSIRO PUBLISHING. This book was released on 2008-08-12 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: Project Vesta was a comprehensive research project to investigate the behaviour and spread of high-intensity bushfires in dry eucalypt forests with different fuel ages and understorey vegetation structures. The project was designed to quantify age-related changes in fuel attributes and fire behaviour in dry eucalypt forests typical of southern Australia. The four main scientific aims of Project Vesta were: To quantify the changes in the behaviour of fire in dry eucalypt forest as fuel develops with age (i.e. time since fire); To characterise wind speed profiles in forest with different overstorey and understorey vegetation structure in relation to fire behaviour; To develop new algorithms describing the relationship between fire spread and wind speed, and fire spread and fuel characteristics including load, structure and height; and to develop a National Fire Behaviour Prediction System for dry eucalypt forests. These aims have been addressed through a program of experimental burning and associated studies at two sites in the south-west of Western Australia.
Download or read book Grassfires written by Phil Cheney and published by CSIRO PUBLISHING. This book was released on 2008 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grassfirespresents the latest information from CSIRO on the behavior and spread of fires in grasslands. This second edition follows ten years of research aimed at improving the understanding of fundamental processes involved in the behavior of bushfires and grassfires. The book has been extensively revised and new case studies have been added to reflect the latest findings in research and investigations. The book covers all aspects of fire behavior and spread in the major types of grasses in Australia. It examines the factors that affect fire behavior in continuous grassy fuels; fire in spinifex fuels; the effect of weather and topography on fire spread; wildfire suppression strategies; and how to reconstruct grassfire spread after the fact. The three fire-spread meters designed by CSIRO and used for the prediction of fire danger and rate of spread of grassfires are explained and their use and limitations discussed. This new edition expands on the historical view of grassfires with respect to extensive Aboriginal burning, combustion chemistry, flame structure and temperature, spotting and spread in discontinuous/eaten out fuels, and the effect of wind in complex terrain. The case studies in the chapter "Wildfires and Their Suppression" have been updated and include the major wild grassfire events of recent years, the January 2003 ACT fires and the 2005 Wangary, SA fire. The "Myths, Facts and Fallacies" chapter includes new myths and a new section on personal safety during a wild grass fire. Of interest to all rural fire fighters and rural landholders, students and teachers of courses on landscape and ecological processes, rural and peri-urban dwellers, fire authorities and researchers.
Download or read book Flames in Our Forest written by Stephen F. Arno and published by Island Press. This book was released on 2013-04-10 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shaped by fire for thousands of years, the forests of the western United States are as adapted to periodic fires as they are to the region's soils and climate. Our widespread practice of ignoring the vital role of fire is costly in both ecological and economic terms, with consequences including the decline of important fire-dependent tree and undergrowth species, increasing density and stagnation of forests, epidemics of insects and diseases, and the high potential for severe wildfires. Flames in Our Forest explains those problems and presents viable solutions to them. It explores the underlying historical and ecological reasons for the problems associated with our attempts to exclude fire and examines how some of the benefits of natural fire can be restored Chapters consider: the history of American perceptions and uses of fire in the forest how forest fires burn effects of fire on the soil, water, and air methods for uncovering the history and effects of past fires prescribed fire and fuel treatments for different zones in the landscape Flames in Our Forest presents a new picture of the role of fire in maintaining forests, describes the options available for restoring the historical effects of fires, and considers the implications of not doing so. It will help readers appreciate the importance of fire in forests and gives a nontechnical overview of the scientific knowledge and tools available for sustaining western forests by mimicking and restoring the effects of natural fire regimes.
