Pyrodiversity – spatiotemporal variation of characteristics within a fire regime – plays an important role in structuring wildlife communities after fire, yet there is a need to better incorporate pyrodiversity into predictive models of animal…

Non‐native, invasive Bromus tectorum (cheatgrass) is pervasive in sagebrush ecosystems in the Great Basin ecoregion of the western United States, competing with native plants and promoting more frequent fires. As a result, cheatgrass invasion likely…

Aim: Pyrodiversity is the spatial or temporal variability in fire effects across a land- scape. Multiple ecological hypotheses, when applied to the context of post- fire sys- tems, suggest that high pyrodiversity will lead to high biodiversity. This…

The impacts of wildfires on the health of children are becoming a more urgent matter as wildfires become more frequent, intense and affecting, not only forested areas, but also urban locations. It is important that medical professionals be prepared…

A recent numerical simulation study by Moinuddin et al. (2018) determined that over a specific range of Froude numbers defined by them as ‘plume mode’, grass fuel height has a strong inverse effect on the rate of fire spread in grasslands. They then…

The world´s forests are one of the largest carbon sinks, making a substantial contribution to counterbalance the increase in atmospheric carbon from anthropogenic sources (Bastin et al., 2019). For this reason, there is broad support to forest…

Heat accumulation from wearing personal protective equipment can result in the development of heat-related illnesses. This study aimed to investigate factors of heat stress with and without a US standard issue wildland firefighter helmet. Ten male…
Year Published:
Understanding tree physiological responses to fire is needed to accurately model post‐fire carbon processes and inform management decisions. Given trees can die immediately or at extended time periods after fire, we combined two experiments to…
Year Published:
Increasing drought and changing temperatures drive researchers to seek more efficient and effective means to aid management of coniferous forests across the western United States. Thinning allows for effective removal of biomass, but with few…
Year Published:
Physical distancing and wearing a face mask are key interventions to prevent COVID-19. While this remains difficult to practice for millions of firefighters in fire engines responding to emergencies, the delayed forthcoming of evidence on the…
Year Published:
Fire spread occurs via radiation, flame contact, and firebrands. While firebrand showers are known to be a cause of spot fires which ignite fuels far from the main fire front, in the case of short distance spot fires, radiation from the main fire…
Year Published:
National forests in the western United States are divided roughly in half between lands without roads managed for wilderness characteristics and lands with an extensive road system managed for multiple uses including resource extraction. We…
Year Published:
Large areal fires, such as those ignited following a nuclear detonation, can inject smoke into the upper troposphere and lower stratosphere. Detailed fire simulations allow for assessment of how local weather interacts with these fires and affects…
Year Published:
Woody plant expansions are altering ecosystem structure and function, as well as fire regimes, around the globe. Tree‐reduction treatments are widely implemented in expanding woodlands to reduce fuel loads, increase ecological resilience, and…
Year Published:
Forest residues and logging slash from pre-commercial forest thinning and regeneration harvests are a potential feedstock for bioenergy production but there has been a concern about the impact of residue removal on forest soil C and N. This study…
Year Published:
Radiological release incidents can potentially contaminate widespread areas with radioactive materials and decontamination efforts are typically focused on populated areas, which means radionuclides may be left in forested areas for long periods of…
Year Published:
In the near future, a higher occurrence of wildfires is expected due to climate change, carrying social, environmental, and economic implications. Such impacts are often associated with an increase of post‐fire hydrological and erosive responses,…
Year Published:
Questions: Invasive‐plant treatments often target a single or few species, but many landscapes are diversely invaded. Exotic annual grasses (EAGs) increase wildfires and degrade native perennial plant communities in cold‐desert rangelands, and…
Year Published:
The ecosystem services provided by forests are under threat as wildfire frequency and severity increase throughout the western US. Severe wildfire can change physical environments and biogeochemical processes in watersheds with lasting effects on…
Year Published:
As anthropogenic emissions continue to decline and emissions from landscape (wild, prescribed, and agricultural) fires increase across the coming century, the relative importance of landscape-fire smoke on air quality and health in the United States…
