Volunteer firefighters often have lower cardiorespiratory fitness (CRF) and less access to health monitoring and fitness programs than career firefighters, yet few studies explore how individual and departmental factors influence their CRF. This…

Altered fire regimes and post-fire tree regeneration failures have the potential to drive forest cover losses throughout western North America, but management practices such as active reforestation may help address these challenges. Planting of…
Year Published:
Forest productivity, essential for climate change mitigation, is increasingly threatened by environmental fluctuations, particularly droughts. Temporal stability in forest productivity —its ability to remain consistent over time— is influenced by…

As wildfires intensify across the western United States, understanding long-term ecosystem recovery is increasingly critical. Post-fire soil amendments, such as woody mulch or biochar, are commonly used to stabilize soils and promote vegetation…
Year Published:
Habitat features associated with species niches are commonly used as biodiversity proxies. Such proxies usually describe habitat diversity and have seldom been evaluated in a forestry context. As demands on forests to mitigate climate change and…

Mechanical thinning is often prescribed in dry coniferous forests to reduce stand density, ladder fuels, and canopy fuels before using prescribed burning to manage surface fuels. Mechanical mastication is a tool for thinning forests where commercial…

Forest restoration treatments in dry conifer forests of the western United States are often done with objectives to move current forest structure toward historical conditions and, in turn, increase the system’s resilience to future wildfires. But…

This study investigates competing vegetation effects on foliar and total plant-derived nutrient ratios, nutrient use efficiency (NUE), and foliar nutrient content and concentration of ecosystem components using vector analysis for 19-year-old…

Light gases were measured in the persistent, intermittent and plume regions of a wildland fire diffusion flame produced by burning longleaf pine needles from the southern United States. This data publication includes measurements taken during a…

Many barriers prevent ranchers from supporting prescribed fire on grazing leases or their own land. Barriers include negative perceptions of fire resources limitations, and fear of liability. We surveyed ranching landowners around four National…

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…

Over the last 20 years, all states within the US have required all cigarettes sold to be “fire safe” or “fire standards compliant” meaning that they must pass ASTM standard E2187. Though these cigarettes are designed to self-extinguish, there have…

The area burned in the western United States during the 2020 fire season was the greatest in the modern era. Here we show that the number of human‐caused fires in 2020 also was elevated, nearly 20% higher than the 1992-2019 average. Although…

Accounting for the effects of fire suppression and containment efforts has posed a challenge in wildfire modeling. Fire suppression is a complex phenomenon depending on factors such as resource availability, weather, terrain, and fire suppression…

Fire-caused tree mortality has major impacts on forest ecosystems. One primary cause of post-fire tree mortality in non-resprouting species is crown scorch, the percentage of foliage in a crown that is killed by heat. Despite its importance, the…
Year Published:
Fuels treatments intended to reduce fuel loads and improve forest health on public lands offer one way to reduce wildfire hazards in the wildland-urban interface (WUI), where the natural and built environments meet. However, for fuels treatment…
Year Published:
Background. Wildland firefighters are exposed to hazards when working which can, and do, result in serious injury or death. Understanding the activities in which firefighters are engaged when they are injured, the hazards to which they were exposed…
Year Published:
Background: Despite progress in reducing industrial air pollution, rising wildfire frequency and intensity, driven in part by climate change, pose significant health risks. Accurate estimates of wildfire-generated fine particulate matter with an…

Fire-caused tree mortality has major impacts on forest ecosystems. One primary cause of post-fire tree mortality in non-resprouting species is crown scorch, the percentage of foliage in a crown that is killed by heat. Despite its importance, the…
Year Published:
-- The mechanistic links between fire-caused injuries and post-fire tree mortality are poorly understood. Current hypotheses differentiate effects of fire on tree carbon balance and hydraulic function, yet critical uncertainties remain about the…
