Are wildfire risk mitigators more prepared to evacuate? Insights from communities in the Western United States
Year: 2025
As the realized experiences of wildfires threatening communities increase, the importance of proactive evacuation preparation and wildfire risk mitigation on private property to reduce the loss of lives and property is shaping wildfire policy and programs. To date, research has focused on pre-wildfire evacuation preparation and risk mitigation independently. This paper examines the substitutability or complementarity of these proactive risk-reducing actions. If mitigation and evacuation preparedness are substitutes, wildfire education programs may take a life-over-property approach. However,…

Location, Location, Location: The Influence of Local Social Complexity on Risk Reduction Strategies in a WUI Settlement
Year: 2025
This research builds from existing scholarship to highlight the important role social complexity plays on managing and mitigating wildfire risk in the wildland-urban interface. Researchers employed in-depth interviews to uncover similarities and differences in land and wildfire management preferences among what would appear to many to be a relatively homogenous population in a valley on the outskirts of Salt Lake City, Utah. In spite of demographic similarities, researchers found meaningful and complex differences with regard to the local social context of subpopulations within the drainage.…

Motivating parents to protect their children from wildfire smoke: the impact of air quality index infographics
Year: 2025
Background. Wildfire smoke events are increasing in frequency and intensity due to climate change. Children are especially vulnerable to health effects even at moderate smoke levels. However, it is unclear how parents respond to Air Quality Indices (AQIs) frequently used by agencies to communicate air pollution health risks. Methods. In an experiment (3 × 2 × 2 factorial design), 2,100 parents were randomly assigned to view one of twelve adapted AQI infographics that varied by visual (table, line, gauge), index type (AQI [0-500], AQHI [1-11+]), and risk…

Long-range PM2.5 pollution and health impacts from the 2023 Canadian wildfires
Year: 2025
Smoke from extreme wildfires in Canada adversely affected air quality in many regions in 20231,2. Here we use satellite observations, machine learning and a chemical transport model to quantify global and regional PM2.5 (particulate matter less than 2.5 μm in diameter) exposure and human health impacts related to the 2023 Canadian wildfires. We find that the fires increased annual PM2.5 exposure worldwide by 0.17 μg m–3 (95% confidence interval, 0.…

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…
