Acquiring detailed 3D fuel data for advanced fire models remains challenging, particularly at large scales. To address this need, we present FastFuels, a novel platform designed to generate detailed 3D fuel data and accelerate the use of advanced…

Background: With wildfires increasing globally due to climate change, children may be more behaviourally exposed and more physiologically vulnerable to adverse health outcomes.
Objective: To complete a comprehensive investigation of epidemiological…

The national Fire and Fire Surrogate (FFS) study was initiated more than two decades ago with the goal of evaluating the ecological impacts of mechanical treatments and prescribed fire in different ecosystems across the United States. Since then, 4…

Background: Existing fire spread models focus exclusively on wildland or urban fire simulation.
Aims: This study aims at an offline coupling of two fire spread models to enable a continuous simulation of a wildfire incident transitioning from…

Background
Rural communities are increasingly impacted by smoke produced by wildfires and forest management activties. Understanding local influences on smoke adaptation and mitigation is critical to social adaptation as fire risk continues to rise…
Year Published:
Wildland fire is increasingly a consequence of the climate crisis, with growing impacts on communities and individuals. Wildland firefighters are critical to the successful management of wildland fire, yet very limited research has considered mental…

Background
Canadian fire managers rely on the value of the Duff Moisture Code (DMC) for estimating lightning ignition and sustained smouldering in ground fuels. A simple rule used widely operationally suggests that lightning does not ignite fires…
Year Published:
Background
Suppression effectiveness is often evaluated by measuring the extent to which it slows fire spread and reduces fireline intensity. Although studies have used infrared (IR) imaging methods to explore suppression effectiveness, most do not…

Background
Air quality modelling of smoke from wildfires requires knowledge of emission factors and how these vary.
Aims
Experimental fires were used to test the variation of emission factors with fuel load to improve a smoke forecasting model.…

Eruptive outbreaks of bark beetles have caused extensive and often severe tree mortality across tens of thousands to millions of hectares in temperate forests since the late 1990s. Many individual bark beetle-host tree (BB-host) associations have…

In the aftermath of deadly blazes in Los Angeles, researchers also suggest ways to make homes more resilient.
The fires that have incinerated large swathes of southern California this month are among the deadliest and most destructive in the state’s…
Year Published:
Background
Acquiring behaviour parameters of wildfire propagation and developing firefighting strategies necessitate a precise and efficient simulation method; fireline coordinates and rate of spread (ROS) are two crucial parameters closely…
Year Published:
Background
The increased interest in why and how trees die from fire has led to several syntheses of the potential mechanisms of fire-induced tree mortality. However, these generally neglect to consider experimental methods used to simulate fire…

In early 2000s, long-distance wind dispersal of mountain pine beetle (MPB; Dendroctonus ponderosae Hopkins) resulted in massive outbreaks in the northern Rocky Mountains, Alberta, Canada, outside of the beetle’s natural range. We analyzed data from…

We consider in the present study an evaluation of the numerical accuracy of the dominant approach used to model the transport of firebrands in landscape-scale fire spread simulators. The approach is based on a prescribed statistical distribution for…
Year Published:
The western United States (U.S.) has been experiencing more severe wildfires, in part due to climate change, but the underlying synoptic patterns and their modulation in driving fire weather is unclear. Here we investigated the relationship between…
Year Published:
With dramatic increases in both area burned and fire severity in Western North American conifer forests, the demand for postfire replanting greatly exceeds land managers’ capacity. Despite the importance of tree planting for forest recovery in many…
Year Published:
Forests are degraded from various factors, and the first step in restoration frequently involves revegetation. One of the degradations is wildfires, which damage vegetation, affect soils, and lead to the loss of ecosystem functions. Using seed…

No Field Evidence of Grass Fuel Structure effects on Postfire Tree Mortality in Juniperus virginiana
Prescribed fires are an important management tool for containing woody plant encroachment in rangeland ecosystems. Grasses are the dominant fuel type in rangelands. Past work has shown that grass canopy architecture, which varies among grass species…
Year Published:
Wildfires and other disturbances play a fundamental role in regenerating lodgepole pine forests. Though severe, stand-replacing fires are typical of this ecosystem, they can have dramatic impacts on soil properties and biogeochemical processes that…
