2012 National Prescribed Fire Use Survey Report
Year: 2012
Science demonstrates that low-intensity surface fires were historically a critical ecological process in as much as 60% of North American landscapes. When applied appropriately in fire-dependent ecosystems, prescribed fire maintains forest health and function, provides habitat for wildlife populations, enhances soil and water conservation, and promotes public health and safety. Prescribed fire is also often required silviculturally to develop, maintain, and protect commercial timber stands. However, its necessary use is often misunderstood, if not unknown, by the public. Societal attitudes…

Scenarios of land use and land cover change in the conterminous United States: Utilizing the special report on emission scenarios at ecoregional scales
Year: 2012
Global environmental change scenarios have typically provided projections of land use and land cover for a relatively small number of regions or using a relatively coarse resolution spatial grid, and for only a few major sectors. The coarseness of global projections, in both spatial and thematic dimensions, often limits their direct utility at scales useful for environmental management. This paper describes methods to downscale projections of land-use and land-cover change from the Intergovernmental Panel on Climate Change's Special Report on Emission Scenarios to ecological regions of the…

The Effect of Large Wildfires on Local Labor Markets
Year: 2012
Although fire managers, policymakers, and communities are benefiting from better understanding of suppression costs, property losses, and community impacts of large fires, no generalizable empirical research has quantified the specific effect of large wildfires on local employment and wages. As federal spending on wildfire suppression in the United States continues to grow, an understanding of the effects of wildfires on local economies will help natural resource managers, policymakers, and communities better anticipate and make management and policy decisions that support local economies.…

Research Perspectives on the Public and Fire Management: A Synthesis of Current Social Science on Eight Essential Questions
Year: 2012
As part of a Joint Fire Science Program project, a team of social scientists reviewed existing fire social science literature to develop a targeted synthesis of scientific knowledge on the following questions: 1. What is the public’s understanding of fire’s role in the ecosystem? 2. Who are trusted sources of information about fire? 3. What are the public’s views of fuels reduction methods, and how do those views vary depending on citizens’ location in the wildland-urban interface or elsewhere? 4. What is the public’s understanding of smoke effects on human health, and what shapes the public’…

Impediments to prescribed fire across agency, landscape and manager: an example from northern California
Year: 2012
Though the need for prescribed fire is widely recognised, its use remains subject to a range of operational and social constraints. Research has focussed on identifying these constraints, yet past efforts have focussed disproportionately on single agencies and geographic regions. We examined constraints on prescribed fire by surveying a wide variety of organisations (including six state and federal agencies and several tribes, non-governmental organisations and timber companies) in northern California, a fire-prone region of the western United States. Across the region, prescribed burning…

Risk and cooperation: managing hazardous fuel in mixed ownership landscapes
Year: 2012
Managing natural processes at the landscape scale to promote forest health is important, especially in the case of wildfire, where the ability of a landowner to protect his or her individual parcel is constrained by conditions on neighboring ownerships. However, management at a landscape scale is also challenging because it requires cooperation on plans and actions that cross ownership boundaries. Cooperation depends on people's beliefs and norms about reciprocity and perceptions of the risks and benefits of interacting with others. Using logistic regression tests on mail survey data and…

Reducing hazardous fuels on nonindustrial private forests: factors influencing landowner decisions
Year: 2011
In mixed-ownership landscapes, fuels conditions on private lands have implications for fire risk on public lands and vice versa. The success of efforts to mitigate fire risk depends on the extent, efficacy, and coordination of treatments on nearby ownerships. Understanding factors in forest owners’ decisions to address the risk of wildland fire is therefore important. This research uses logistic regression to analyze mail survey data and identify factors in forest owners’ decisions to reduce hazardous fuels in the ponderosa pine (Pinus ponderosa) ecosystem on the east side of Oregon. Results…

Northwest Forest Plan -- The First 15 Years: Status and Trends of Northern Spotted Owl Populations and Habitats
Year: 2011
This is the second in a series of periodic monitoring reports on northern spotted owl (Strix occidentalis caurina) population and habitat trends on federally administered lands since implementation of the Northwest Forest Plan in 1994.Here we summarize results from a population analysis that included data from long-term demographic studies during 1985–2008. This data was analyzed separately by study area, and also in a meta-analysis across all study areas to assess temporal and spatial patterns in fecundity, apparent survival, recruitment, and annual rates of population change. Estimated…

Both topography and climate affected forest and woodland burn severity in two regions of the western US, 1984 to 2006
Year: 2011
Fire is a keystone process in many ecosystems of western North America. Severe fires kill and consume large amounts of above- and belowground biomass and affect soils, resulting in long-lasting consequences for vegetation, aquatic ecosystem productivity and diversity, and other ecosystem properties. We analyzed the occurrence of, and trends in, satellite-derived burn severity across six ecoregions in the Southwest and Northwest regions of the United States from 1984 to 2006 using data from the Monitoring Trends in Burn Severity project. Using 1,024 fires from the Northwest (4,311,871 ha) and…

Assessing fuel treatment effectiveness using satellite imagery and spatial statistics
Year: 2009
Understanding the influences of forest management practices on wildfire severity is critical in fire-prone ecosystems of the western United States. Newly available geospatial data sets characterizing vegetation, fuels, topography, and burn severity offer new opportunities for studying fuel treatment effectiveness at regional to national scales. In this study, we used ordinary least-squares (OLS) regression and sequential autoregression (SAR) to analyze fuel treatment effects on burn severity for three recent wildfires: the Camp 32 fire in western Montana, the School fire in southeastern…

Smoke on the hill: A comparative study of wildfire and two communities
Year: 2003
Wildfire represents a serious challenge to communities in the rural West. After decades of fire suppression, land managers now perceive a greater role for wildfire in the ecosystem. In the meantime, migration patterns from urban to rural settings have increased the number of people living in forested areas throughout the West, therefore; wildfires are a threat to more homes than ever in the region. This study focuses on two communities’ response to wildfires during the intense fire season of 1994. Through qualitative research methods, the study analyzes these diverse responses in the context…
