Background
Wildland fuels are fundamental variables in modeled predictions of fire behavior and effects. In forest ecosystems, accumulated forest floor layers, including recently fallen litter and highly decomposed organic material (i.e., duff),…

Background
Vegetation, terrain and weather properties vary greatly spatially and temporally, all of which influence fire behavior.
Aims
This study aims to enhance the applicability and predictive accuracy of the Rothermel model for mixed fuel spread…

Background
Increasing wildfire area burned has left millions of hectares in the western United States (US) in need of reforestation. Recent federal legislation allows for increased investments in tree planting to address the backlog of planting…
Year Published:
Wild and intentionally ignited fires are not new to North American landscapes or to the Indigenous cultures whose ancestral places encompass them. For millennia, Indigenous fire stewardship has been regionally and locally distributed across North…
Year Published:
Understanding where animals graze and why they choose to graze there can be critical to rangeland and ecosystem management with misunderstandings of grazing distribution and behavior often being detrimental to management goals. Over time, grazing…
Year Published:
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:
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…
