Exploring Wildfire Preparedness, Perceptions, and Responses in Western Canada: Insights from Valemount, British Columbia
Year: 2025
Climate change and decades of fire suppression are increasing the risk of wildfire in many rural and remote communities across Canada. Yet limited research has been done to better understand how these communities experience wildfire risk. For this research, conducted prior to the catastrophic wildfire season of 2023 in British Columbia, we interviewed 20 key informants living in the village of Valemount in the Robson Valley, British Columbia, about their perceptions of wildfire risk, lived experiences, and management approaches. We further explored barriers to and opportunities for future…

Wildland Fire–Related Smoke PM2.5 and Cardiovascular Disease Emergency Department Visits in the Western United States
Year: 2025
BackgroundThe impact of short‐term exposure to fine particulate matter with a diameter ≤2.5 μm (PM2.5) due to wildland fire smoke on the risk of cardiovascular disease (CVD) remains unclear. We investigated the association between short‐term exposure to wildfire smoke PM2.5 and emergency department visits for acute CVD in the western United States from 2007 to 2018.MethodsWe analyzed 49 759 958 emergency department visits for primary or secondary diagnoses of atrial fibrillation (AF), acute myocardial infarction, heart failure, stroke, and total CVD across 5…

Innovation to support wildfire risk-based decision-making: examining the incident strategic alignment process
Year: 2025
BackgroundIn the face of increased complexity, the USDA Forest Service (Forest Service) is emphasizing the use of risk-based spatial analytics and expert coaching of fire managers through consistent processes and practices to inform safer, effective, and strategic decision-making during incident management. The Incident Strategic Alignment Process (ISAP) integrates collaborative dialogue with risk management assistance (RMA) and other spatial analytics to develop and deploy a consistent, science-based strategic planning model for incident management. An important challenge is…

Insights into how Community Wildfire Protection Plans act as drivers of wildfire preparedness
Year: 2025
Wildfire poses an increasing threat to communities in the Western US, driven by climate change and rising human settlement in the wildland-urban interface (WUI). It is imperative that communities in fire-prone areas become “fire-adapted” to safely manage their risk. Community Wildfire Protection Plans (CWPPs) constitute an approach by the federal government to enable communities to collaboratively plan for, and adapt to, wildfire. How well these plans have enabled at-risk rural Colorado communities to become “fire-adapted” since their development is still debated. Through interviews with key…

A tale of two fire systems: indigenous fire stewardship in British Columbia and California
Year: 2025
BackgroundAn increasing wildfire problem in western North America has created a policy space for Indigenous fire stewardship (IFS) to mitigate wildfire. We compare how British Columbia and California have supported IFS—two jurisdictions with distinct ecosystems but similar histories of colonialism and its socio-ecological consequences. We examine how IFS is incorporated into each jurisdiction’s institutional framework, and the barriers to, and opportunities for implementation.ResultsEach jurisdiction’s approach to recognizing IFS is shaped by different…

Outcome efficacy and responsibility as correlates of household wildfire adaptation action in Boulder, CO
Year: 2025
Growing wildfire risks are increasing losses and damages to wildland-urban interface households in the American West. In Colorado, the December 2021 Marshall Fire destroyed over 1000 suburban homes and became the most destructive fire in the state's history and the 10th costliest in US history. Fortunately, homeowner adaptation action can play a significant role in preventing structural damage or loss that can come from a wildfire. Yet, action is more effective when coordinated across a community, since the nature of wildfire as a hazard means that one homeowner's wildfire risk is informed…

Causal analysis of fire regime drivers in California
Year: 2025
BackgroundUnderstanding the relative contribution of climate and human factors to wildfires is critical for managing risk across California’s diverse ecosystems, in the United States (US).AimsWe propose a model that distinguishes between proximate and ultimate drivers of fire regimes and apply it to a century of fire and climate data to assess regional variation in causal mechanisms.MethodsWe analyzed fire statistics (1910–2021) alongside climate and weather data, stratifying the state by 10 ecoregions.Key resultsNorthern…

Valuing co-benefits of forest fuels treatment for reducing wildfire risk in California's Sierra Nevada
Year: 2025
As wildfires in the western United States grow in frequency and severity, forest fuels treatment has been increasingly recognized as essential for enhancing forest resilience and mitigating wildfire risks. However, the economic valuation of the treatment's co-benefits remains underexplored, limiting integration into financial and policy decision making. Using highly forested land in California's Sierra Nevada as study areas, this study provides a methodology to quantify the economic benefits of forest fuels treatment in mitigating wildfire-induced losses across multiple ecosystem services,…

Roof renewal disparities widen the equity gap in residential wildfire protection
Year: 2025
Wildfires are having disproportionate impacts on U.S. households. Notably, in California, over half of wildfire-destroyed homes (54%) are in low-income areas. We investigate the relationship between social vulnerability and wildfire community preparedness using building permits from 16 counties in California with 2.9 million buildings (2013–2021) and the U.S. government’s designation of disadvantaged communities (DACs), which classifies a census tract as a DAC if it meets a threshold for certain burdens, such as climate, environmental, and socio-economic. Homes located in DACs are 29% more…

Spatiotemporal Synchrony of Climate and Fire Occurrence Across North American Forests (1750–1880)
Year: 2025
Aim: Increasing aridity has driven widespread synchronous fire occurrence in recent decades across North America. The lack of historical (pre-1880) fire records limits our ability to understand long-term continental fire-climate dynamics. The goal of this study is to use tree-ring reconstructions to determine the relationships between spatiotemporal patterns in historical climate and widespread fire occurrence in North American forests, and whether they are stable through time. This information will address a major knowledge gap required to inform projections of future fire.Location: North…

Patterns and trends of heat and wildfire smoke indicators across rural–urban and social vulnerability gradients in Idaho
Year: 2025
Climate change poses a grave threat to human health with disparate impacts across society. While populations with high social vulnerability generally bear a larger burden of exposure to and impact from environmental hazards; such patterns and trends are less explored at the confluence of social vulnerability and rural–urban gradients. We show that in rural regions in Idaho, low vulnerability populations had both the highest long-term average and the highest increase rate of exposure to heatwaves from 2002–2020, coincident with a higher population density in low—as compared to high—…

Compounding effects of climate change and WUI expansion quadruple the likelihood of extreme-impact wildfires in California
Year: 2025
Previous research has examined individual factors contributing to wildfire risk, but the compounding effects of these factors remain underexplored. Here, we introduce the “Integrated Human-centric Wildfire Risk Index (IHWRI)” to quantify the compounding effects of fire-weather intensification and anthropogenic factors—including ignitions and human settlement into wildland—on wildfire risk. While climatic trends increased the frequency of high-risk fire-weather by 2.5-fold, the combination of this trend with wildland-urban interface expansion led to a 4.1-fold increase in the frequency of…
