Global fire regime change is threatening terrestrial biodiversity. Understanding how these changes affect biota is essential to protect biodiversity now and into the future. A targeted examination of the mechanisms through which fire influences…
Year Published:
An overview, including background motivation for the event and plans for future events, of the 2025 Fire and Fuels Monitoring Workshop hosted by NW Bureau of Indian Affairs (BIA), US Forest Service (USFS) PNW region, Northern Rockies Fire Science…
Year Published:
Background: Drought, human disturbance, and invasive species are reshaping disturbance regimes and increasing the scale, severity, and frequency of wildfire in many ecosystems around the globe, including the sagebrush steppe of western North America…
Year Published:
Forest managers are faced with escalating size, severity, and cost of wildfires. To mitigate this, U.S. federal land management agencies are increasing forest treatments such as mechanical thinning and prescribed fire. While there is a growing body…
Year Published:
The gas and tar composition of a wildland fire diffusion flame from longleaf pine needles is currently relatively unmeasured and more data are needed to fill in the gap between pyrolysis data and smoke plume data, thus improving physical and…
Year Published:
This paper numerically investigates the effects of ambient wind and sloped terrains on the behavior of moving fire whirls using Fire Dynamics Simulator (6.7.6). Five configurations were designed, including small- and large-scale L-shaped fire…
Year Published:
Fire regimes are shifting around the world due to climate and land-use change, resulting in an increased frequency of large and severe wildfires. However, the impact of extreme wildfire events on animal species remains poorly understood.…
Year Published:
Forest fires not only destroy vegetation and directly decrease forested areas, but they also significantly impair forest stand structures and habitat conditions, ultimately leading to imbalances within the entire forest ecosystem. Therefore,…
Year Published:
Tree phenotypes vary because of genotype–climate interactions, and this variation influences host selection by tree-killing bark beetles. As climate-driven bark beetle outbreaks intensify, identifying phenotypic traits that best predict resistance…
Year Published:
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…
Year Published:
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…
Year Published:
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…
Year Published:
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…
Year Published:
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…
Year Published:
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…
Year Published:
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…
Year Published:
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…
Year Published:
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…
