Wildfires in the western United States are concerning in part because conifer forests may not regenerate under increasingly warm, dry climate conditions and severe burning. This study compared the relative importance of differences in fire-caused…

Wildfires are common occurrences worldwide that can destroy vast forest areas and kill numerous animals in a few hours. Climate change, rising global temperatures, precipitation, the introduction of exotic species of plants (e.g., eucalyptus),…

Salvage logging is a controversial tool for post-wildfire management that removes fire-killed trees. We use a generalized randomized experimental design to fulfill two main objectives: (1) quantify the immediate (1-year post-harvest) effects of…

Soil moisture conditions are represented in fire danger rating systems mainly through simple drought indices based on meteorological variables, even though better sources of soil moisture information are increasingly available. This review…
Year Published:
Wildfires are increasing in scale and impact on the landscape, altering large amounts of wildlife habitat and forest ecosystems. The reduction of fuels through forest management is considered a primary way to reduce the extent and severity of…
Year Published:
The authors are a team of fire whirl researchers who have been actively studying whirls and large-scale wildland fires by directly observing them through fire-fighting efforts and applying theory, scale modeling, and numerical simulations in fire…

The behaviour of wildland fires and the dispersion of smoke from those fires can be strongly influenced by atmospheric turbulent flow. The science to support that assertion has developed and evolved over the past 100+ years, with contributions from…

Firebrand showers are known to result in massive destruction in large outdoor fires. A key missing piece is how these ignition scenarios may be influenced by firebrand showers in conjunction with external radiant heat that would be generated by…

This study 1) identifies the seasons and biomes that exhibit significant (1980–2019) changes in fire danger potential, as quantified by the Canadian Fire Weather Index (FWI); 2) explores what types of fire behavior potentials may be contributing to…
Year Published:
Wildfires are a global crisis, but current fire models fail to capture vegetation response to changing climate. With drought and elevated temperature increasing the importance of vegetation dynamics to fire behavior, and the advent of next…
Year Published:
Quaking aspen (Populus tremuloides Michx.) stands have historically been referred to as “firebreak” forest types that can reduce fire activity, but high-intensity and high-severity fires have been observed to burn through aspen stands. Clearly, fire…
Year Published:
Invasive annual grasses are a growing global concern because they facilitate larger and more frequent fires in historically fuel-limited ecosystems. Forests of the western United States have remained relatively resistant to invasion by annual…

Aim
Ecological disturbances are increasing as climate warms, and how multiple disturbances interact spatially to drive landscape change is poorly understood. We quantified burn severity across fire regimes in reburned forest landscapes to ask how…

Background: Understanding near-surface fire–atmosphere interactions at turbulence scale is fundamental for predicting fire spread behaviour.
Aims: This study aims to investigate the fire–atmosphere interaction and the accompanying energy transport…
Year Published:
Rapidly identifying high-risk areas for potential wildfires is crucial for preparedness, disaster management, and operational logistics decisions. With the advancement of technologies such as Cloud computing, high-risk areas can be determined ahead…
Year Published:
The concurrent impacts of fire suppression, climate-warming, and industrial forestry have dramatically altered the spatio-temporal patterns of fire across the globe. Pyrophilic insects are among the species most threatened by these changes due to…
Year Published:
Firebrand spotting is a major cause for structure losses in wildland-urban interface (WUI) fires. When firebrands land nearby and accumulate into groups or piles, they can act as a more competent ignition source compared to single firebrands. While…
Year Published:
Increasing fire activity and the associated degradation in air quality in the United States has been indirectly linked to human activity via climate change. In addition, direct attribution of fires to human activities may provide opportunities for…

Background
Wildfire management is increasingly shifting from firefighting to wildfire prevention aiming at disaster risk reduction. This implies fuel and landscape management and engagement with stakeholders. This transition is comparable to the…

Disruption of photosynthesis and carbon transport due to damage of the tree crown and stem cambial cells, respectively, can cause tree mortality. It has recently been proposed that fire-induced dysfunction of xylem plays an important role in tree…
