Value And Challenges Of Conducting Rapid Response Research On Wildland Fires

This synthesis of post-fire treatment effectiveness reviews the past decade of research, monitoring, and product development related to post-fire hillslope emergency stabilization treatments, including erosion barriers, mulching, chemical soil treatments, and combinations of these treatments. In the past ten years, erosion barrier treatments (contour-felled logs and straw wattles) have declined in use and are now rarely applied as a post-fire hillslope treatment. In contrast, dry mulch treatments (agricultural straw, wood strands, wood shreds, etc.) have quickly gained acceptance as effective, though somewhat expensive, post-fire hillslope stabilization treatments and are frequently recommended when values-at-risk warrant protection. This change has been motivated by research that shows the proportion of exposed mineral soil (or conversely, the proportion of ground cover) to be the primary treatment factor controlling post-fire hillslope erosion. Erosion barrier treatments provide little ground cover and have been shown to be less effective than mulch, especially during short-duration, high intensity rainfall events. In addition, innovative options for producing and applying mulch materials have adapted these materials for use on large burned areas that are inaccessible by road. Although longer-term studies on mulch treatment effectiveness are on-going, early results and short-term studies have shown that dry mulches can be highly effective in reducing post-fire runoff and erosion. Hydromulches have been used after some fires, but they have been less effective than dry mulches in stabilizing burned hillslopes and generally decompose or degrade within a year.

This textbook provides students and academics with a conceptual understanding of fire behavior and fire effects on people and ecosystems to support effective integrated fire management. Through case studies, interactive spreadsheets programmed with equations and graphics, and clear explanations, the book provides undergraduate, graduate, and professional readers with a straightforward learning path. The authors draw from years of experience in successfully teaching fundamental concepts and applications, synthesizing cutting-edge science, and applying lessons learned from fire practitioners. We discuss fire as part of environmental and human health. Our process-based, comprehensive, and quantitative approach encompasses combustion and heat transfer, and fire effects on people, plants, soils, and animals in forest, grassland, and woodland ecosystems from around the Earth. Case studies and examples link fundamental concepts to local, landscape, and global fire implications, including social-ecological systems. Globally, fire science and integrated fire management have made major strides in the last few decades. Society faces numerous fire-related challenges, including the increasing occurrence of large fires that threaten people and property, smoke that poses a health hazard, and lengthening fire seasons worldwide. Fires are useful to suppress fires, conserve wildlife and habitat, enhance livestock grazing, manage fuels, and in ecological restoration. Understanding fire science is critical to forecasting the implication of global change for fires and their effects. Increasing the positive effects of fire (fuels reduction, enhanced habitat for many plants and animals, ecosystem services increased) while reducing the negative impacts of fires (loss of human lives, smoke and carbon emissions that threaten health, etc.) is part of making fires good servants rather than bad masters.

Wildfires represent a growing threat to environments, to people, communities, and to societies worldwide, particularly in the United States, Southern Europe, and Australia. Recognition of this growing risk has highlighted a need to develop people's capacity to adapt to annually occurring events that could increase in frequency and severity over the coming years and decades. The goal of ensuring sustained levels of protective measures in communities susceptible to wildfire hazard consequences has proved to be elusive. This book examines why this is so and identifies ways in which sustained levels of preparedness can be facilitated. Major topics include: wildfire preparedness and resiliency in community contexts; socially disastrous landscape fires in southeastern Australia; landscape typology of residential wildfire risk; proactive human response to wildfires outbreak; forest fires in wildland-urban interface, wildfire risk management; “stay or go” policy in the line of fire; social dimensions of forest fire; the influence of community diversity; evaluating a community engagement initiative; response to fire threats; social media and resiliency; and building on lessons learned. Additional information includes the landscape fires in southeastern Australia, wildfire risk management in Portugal; fire preparedness in Greece, Cyprus, and the Pine Barrens in the northeastern United States. The findings of research programs being conducted in the United States, Australia, Europe, India and South America are presented. The book includes case studies on the analysis and proposed actions of the wildland-urban interface being faced by Central Chile and South America. This book will provide a comprehensive and systematic review of the wildfire preparedness research and its application to the development of risk communications and public education programs.
