Exceptional events occur when air pollution in a specific location exceeds the National Ambient Air Quality Standards (NAAQS) due to an event that cannot be reasonably attributed to human activities, such as a wildland fire. Ground-level ozone (O3)…
Year Published:
Dangerous wildfire conditions continue to threaten people and ecosystems across the globe and cooperation is critical to meeting the outsized need for increased prescribed burning in wildfire risk reduction work. Despite the benefits of using…
Year Published:
Policy initiatives such as the Collaborative Forest Landscape Restoration Program (Rep. Holt, 2009) have emphasized landscape-scale (> 10,000 ac) fuel reduction treatments to mitigate adverse impacts of large, uncharacteristic wildfires in the…

As the need for wildfire adaptation for human populations in the wildland-urban interface (WUI) intensifies in the face of changes that have increased the number of wildfires that exceed 100 thousand acres, it is becoming more important to come to a…
Year Published:
Pile burning is the most common method of logging residue disposal in Rocky Mountain forests. Though the high temperatures reached during burning affect numerous soil properties in the short term, the longer-term effects of the practice are less…

The purpose of this study was to investigate the merging behavior of small-scale buoyant flames that might be representative of flames from a leaf in a shrub. Zirconia felt pads soaked in n-heptane were suspended on thin rods and spaced both…
Year Published:
Abandonment of agricultural land is widespread in many parts of the world, leading to shrub and tree encroachment. The increase of flammable plant biomass, that is, fuel load, increases the risk and intensity of wildfires. Fuel reduction by…

Wildland firefighters (WLFFs) perform in adverse environments making rapid adjustments to dietary needs. The National Mobile Food Services (NMFS) contract details WLFF dietary provisions on wildfire incidents.
Objective: Determine the nutrient…

Quaking aspen, Populus tremuloides, has experienced severe declines in recent years in part due to the effects of changing climate and extreme drought. This study set out to investigate these effects by assessing associations of climatic, edaphic…
Year Published:
Daily, fine-scale spatially explicit wildland fire occurrence prediction (FOP) models can inform fire management decisions. Many different data-driven modelling methods have been used for FOP. Several studies use multiple modelling methods to…

Despite the increasing challenges wildfires are posing around the globe, and the flourishing production of high-quality wildfire scientific knowledge, the ability of fire science to impact knowledge on the ground, for people, society, economy, and…
Year Published:
Wildfire is increasing in frequency and size in the western United States with climate change and invasive species such as cheatgrass. This increase is also causing an increase in the need for restoration techniques, especially in low-elevation,…
Year Published:
Wildfires significantly influence ecosystem patterns and processes on a global scale. In many cases, they pose a threat to human lives and property. Through greenhouse gas emissions, wildfires also directly contribute to climate change. The…
Year Published:
As global warming continues, wildland lightning fires have exhibited an increasing trend. The phenomenon of lightning ignition and a model are urgent research fields. In this study, an impulse current generator was used to study artificial lightning…
Year Published:
Wildfires are occurring more frequently and with greater severity domestically and around the globe. Across a series of studies, researchers at the University of Idaho set out to identify how and when climate variability affects wildfire frequency…
Year Published:
Wildfire size and frequency have increased in the western United States since the 1950s, but it is unclear how seeding treatments have altered fire regimes in arid steppe systems. We analyzed how the number of fires since 1955 and the fire return…
Year Published:
The effectiveness of a fuelbreak, created in a homogeneous grassland on a flat terrain, was studied numerically. The analysis relies on 3D numerical simulations that were performed using a detailed physical-fire-model (FIRESTAR3D) based on a…
