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…

Canopy height models (CHMs) with sufficient resolution to distinguish individual trees are useful for a variety of applications. However, standard techniques to acquire such data, such as airborne lidar surveying, are often prohibitively expensive.…
Year Published:
Background. Wildfires, prescribed fires and slash-pile burns are disturbances that occur in many terrestrial ecosystems. Such fires produce variable surface heat fluxes causing a spectrum of effects on soil, such as seed mortality, nutrient loss,…
Year Published:
This research presents a scientifically grounded model designed to enhance the safety protocols for firefighting teams during fire intervention scenarios. The model estimates the maximum allowable exposure duration based on ambient temperature and…

This research brief discusses considerations for prescribed burning and fuels treatments in whitebark pine, including best practices and layout options for large- and small-scale treatments.
Year Published:
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…
Year Published:
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…

Changing global climate and wildfire regimes are threatening forest resilience (i.e., the ability to recover from disturbance). Yet distinguishing areas of “no” versus “slow” postfire forest recovery is challenging, and consequences of sparse tree…

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.…
Year Published:
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…

In 2023, all regions of British Columbia (BC) experienced record-breaking fire weather and wildfires, with extreme behavior and social-ecological effects. In total, 2245 wildfires burned 2840 545 hectares. Contemporary wildfires are the culmination…

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:
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…

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…
