In the present experiment we evaluated the impact of rapid heat stress on decision-making and neural function. Previous work has demonstrated that heat stress has an impact on cognitive and neural function. Here, we hypothesized that a rapid…

Coupled fire-atmospheric modeling tools are increasingly used to understand the complex and dynamic behavior of wildland fires. Multiple research tools linking combustion to fluid flow use Navier-Stokes numerical solutions coupled to a thermodynamic…

Particularly in rural settings, there has been little research regarding the health impacts of fine particulate matter (PM2.5) during the wildfire season smoke exposure period on respiratory diseases, such as influenza, and their associated…

The Wildfire Research Center (WiRe Center) works with wildfire practitioners seeking to create communities that are adapted to wildfire using an evidenced-based approach. Historically, immediate threats and wildfire suppression have garnered much…

Municipal firefighters count on their protective garments to avoid skin burns caused by thermal and flame exposures. Typical firefighting garment consists of three layers of different fire-resistant fabrics named as outer shell, moisture barrier and…

In 2018, Fire Management Today carried an article on smoke exposure (6 Minutes for Safety 2018). The article describes actions you can take to mitigate smoke exposure and techniques for reducing the exposure of firefighters to heavy smoke. The…

Post-incident studies provide direct and valuable information to further the scientific understanding of Wildland-Urban Interface (WUI) fires. Most post-incident studies involve data collection in the field (i.e. a 'research field deployment'). In…

With increasing heat and droughts world-wide, wildfires are becoming a more serious global threat to the world’s population. Wildfire smoke is composed of approximately 80% to 90% of fine (<2.5 um) and ultrafine (<1 um) particulate matter (PM…

High severity wildfires impact hillslope processes, including infiltration, runoff, erosion, and sediment delivery to streams. Wildfire effects on these processes can impair vegetation recovery, producing impacts on headwater and downstream water…
Year Published:
Potential impacts of soil temperatures in a post-fire environment were examined for seeds of legume species with a physical seed dormancy typically found in the eucalypt communities in eastern Australia. Soil temperatures in a post-fire environment…
Year Published:
Wildfire danger assessment is essential for operational allocation of fire management resources; with longer lead prediction, the more efficiently can resources be allocated regionally. Traditional studies focus on meteorological forecasts and fire…

Salvage logging in burned forests can negatively affect habitat for white-headed woodpeckers (Dryobates albolarvatus), a species of conservation concern, but also meets socioeconomic demands for timber and human safety. Habitat suitability index (…

Late-1800s land surveys were used to reconstruct historical forest structure and fire over more than 235,000 ha in ponderosa pine and mixed conifer landscapes of the San Juan Mountains, Colorado, to further understand differences among regional…

Natural disastrous events are part and parcel of our times and do occur when we least expect it to strike us. Disasters which take place in the vicinity of human livelihood due to natural causes, such as forest fires, tsunami, earthquakes, floods,…
Year Published:
Traditional methods for assessing fire danger often depend on meteorological forecasts, which have reduced reliability after ∼10 d. Recent studies have demonstrated long lead-time correlations between pre-fire-season hydrological variables such as…

Aims: Wildfires in dry forest ecosystems in western North America are producing fire effects that are more severe than historical estimates, raising concerns about the resilience of these landscapes to contemporary disturbances. Despite increasing…
Year Published:
The increasing amount of high-severity wildfire in historical low and mixed-severity fire regimes in western US forests has created a need to better understand the ecological effects of different post fire management approaches. For three different…
Year Published:
In large-scale mass fires generated in forests or by a nuclear event, the area of the fire is large (diameter 1 or more kilometers) whereas the flame height is relatively small (less than 10 m) creating a large turbulent buoyant plume. This paper…
Year Published:
Wildfires are a serious threat to ecosystems and human life. Usually, smoke is generated before the flame, and due to the diffusing nature of the smoke, we can detect smoke from a distance, so wildfire smoke detection is especially important for…

To improve access and understanding of postfire resources, scientists with the Rocky Mountain Research Station and its partners have drawn on years of science/management collaboration to compile an online resource called the After Fire Toolkit and…
