Indigenous land stewardship and mixed-severity fire regimes both promote landscape heterogeneity, and the relationship between them is an emerging area of research. In our study, we reconstructed the historical fire regime of Ne Sextsine, a 5900-ha…

Post-fire debris flows represent one of the most erosive consequences associated with increasing wildfire severity and investigations into their downstream impacts have been limited. Recent advances have linked existing hydrogeomorphic models to…

The wildfire season in the Western United States (U.S.) was anomalously large in 2020, with a majority of burned area due to lightning ignitions resulting in overall fire emissions of carbon monoxide (CO) in the Western region almost 3 times the…

Background: Wildfires propagate through vegetation exhibiting complex spread patterns modulated by ambient atmospheric wind turbulence. Wind gusts at the fire-front extend and intensify flames causing direct convective heating towards unburnt fuels…
Year Published:
Large quantities of dead wood can be generated by disturbances such as wildfires. Dead trees created by disturbances play many critical ecological roles in forest ecosystems globally. The ability of deadwood to serve its ecological roles is…
Year Published:
Plantations of trees are key sources of wood products globally and are increasing in extent in many jurisdictions around the world. Plantations also can be flammable and fire prone with extensive areas of the existing plantation estate being burnt…

The concept of discrete fuels provides a good representation of the real fire scenario. Many efforts on this issue have been conducted with the aid of heat transfer analyses, while little work has focused on the mass transfer analyses, nor…

The wildland-urban interface (WUI), where housing intermingles with wildland vegetation, is the fastest-growing land use type in the United States. Given the ecological and social benefits of forest ecosystems, there is a growing need to more fully…

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…

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…

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…

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…
Year Published:
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…

Columbian sharp-tailed grouse (Tympanuchus phasianellus columbianus) are endemic to grassland and shrub-steppe ecosystems of western North America, yet their distribution has contracted to <10% of their historical range. Primary threats to…
Year Published:
Background: Maximizing the effectiveness of fuel treatments at landscape scales is a key research and management need given the inability to treat all areas at risk from wildfire. We synthesized information from case studies that documented the…
Year Published:
Vegetation structure affects the vulnerability of a forest to drought events and wildfires. Management decisions, such as thinning intensity and type of understory treatment, influence competition for water resources and amount of fuel available.…

Serotinous cones, those that remain closed until heated, confer post-disturbance resilience on many lodgepole pine forests throughout the Southern Rockies. The record-breaking extent of wildfires in northern Colorado and southern Wyoming in 2020…

The Economic Value of Fuel Treatments: A Review of the Recent Literature for Fuel Treatment Planning
This review synthesizes the scientific literature on fuel treatment economics published since 2013 with a focus on its implications for land managers and policy makers. We review the literature on whether fuel treatments are financially viable for…
