Background: Contemporary and projected shifts in global fire regimes highlight the importance of understanding how fire affects ecosystem function and biodiversity across taxa and geographies. Pyrodiversity, or heterogeneity in fire history, is…
Year Published:
Terrestrial LiDAR scans (TLS) offer a rich data source for high-fidelity vegetation characterization, addressing the limitations of traditional fuel sampling methods by capturing spatially explicit distributions that have a significant impact on…
Year Published:
In the United States (US), forest ecosystems are the largest terrestrial carbon sink, offsetting the equivalent of >12 % of economy-wide greenhouse gas (GHG) emissions annually. In the Western US, wildfires have shaped much of the landscape by…
Year Published:
Background: Current guidance for implementation of United States federal wildland fire policy charges agencies with restoring and maintaining fire-adapted ecosystems while limiting the extent of wildfires that threaten life and property, weighed…
Year Published:
Fuel is the part of the fire behavior triangle that we can directly affect. So, we know that we need to get more proactive with fuels treatments and prescribed fire if we want to get a better handle on the fire situation. As we shift towards more…
Year Published:
We developed and applied a spatial optimization algorithm to prioritize forest and fuel management treatments within a proposed linear fuel break network on a 0.5 million ha Western US national forest. The large fuel break network, combined with the…
Year Published:
Runoff-generated debris flows are a potentially destructive and deadly response to wildfire until sufficient vegetation and soil-hydraulic recovery have reduced susceptibility to the hazard. Elevated debris-flow susceptibility may persist for…
Year Published:
Background: Planting tree seedlings may help promote forest recovery after extensive high-severity wildfire. We evaluated the influence of growing environment characteristics on the performance of seedlings planted in the 2016 Cold Springs Fire,…
Year Published:
For the past 20 to 30 years, a wildfire crisis has been building in the West as wildfires have grown in size, duration, and destructivity despite highly effective suppression responses by the USDA Forest Service and others in the wildland fire…
Year Published:
(1) Background: When a fire breaks out, combustibles are burned and toxic substances such as carbon monoxide (CO), polycyclic aromatic hydrocarbons (PAH), benzene, and hydrogen cyanide are produced. The purpose of this study is to evaluate the air…
Year Published:
We aim to assess small airway dysfunction, spirometry, health-related quality of life (HR-QoL), and inflammatory biomarkers between the wildland firefighters and healthy controls. Lung function including impulse oscillometry (IOS) and spirometry, HR…
Year Published:
Fire management aims to change fire regimes. However, the challenge is to provide the optimal balance between the mitigation of risks to life and property, while ensuring a healthy environment and the protection of other key values in any given…
Year Published:
Dry conifer forests in the western US historically experienced frequent fire prior to European American colonization. Mean fire return interval ranged from about 5-35 years, with the majority of fires burning at low-to-moderate severity. The arrival…
Year Published:
The increase of wildfire disasters globally has highlighted the need to understand and mitigate human vulnerability to wildfire. In response, there has been a substantial uptick in efforts to characterize and quantify wildfire vulnerability. Such…
Year Published:
Fuel ignition potential is one of the primary drivers influencing the extent of damage in wildland and wildland–urban interface fires and it is a decisive factor in planning prescribed fires. Determining the susceptibility of fuels, which vary…
Year Published:
Background: Fire whirl is an extreme fire behaviour in wildland fires, and an essential factor for its formation is the surrounding generating eddy. No systematic experimental study has been conducted on natural fire whirls with varying heights of…
Year Published:
The escalating climate and wildfire crises have generated worldwide interest in using proactive forest management (e.g. forest thinning, prescribed fire, cultural burning) to mitigate the risk of wildfire-caused carbon loss in forests. To estimate…
Year Published:
The goal of this work is to develop a material model for Norway spruce and Scots pine woods for use in performance-based fire safety design to predict char front progress and heat release in burning timber. For both woods a set of two different…
Year Published:
Background: An effective identification model is crucial to realise the real-time monitoring and early warning of forest fires from surveillance cameras. However, existing models are prone to generate numerous false alarms under the interference of…
Year Published:
Increasing area burned across western North America raises questions about the precedence and magnitude of changes in fire activity, relative to the historical range of variability (HRV) that ecosystems experienced over recent centuries and…
