Prescribed fall burning is commonly used worldwide on rangeland sites to enhance vegetation resources and restore disturbed ecosystems, but little is known about how it may alter microbial communities and insect activities. We used two site…

(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…

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…

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…

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…

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:
Appropriately designed fuel treatments reduce negative outcomes of wildfire and in some cases promote beneficial wildfire outcomes. Wildfires are a landscape scale phenomenon; therefore, fuel treatments should be evaluated at a landscape level to…
Year Published:
The increasing complexity and impacts of fire seasons in the United States have prompted efforts to improve early warning systems for wildland fire management. Outlooks of potential fire activity at lead-times of several weeks can help in wildland…
Year Published:
Monitoring ecosystem status and recovery potential is critical for natural resource management. Recent evidence in ecological studies suggest a fundamental link between ecosystem physical structure and function, including resistance and recovery.…
Year Published:
A deeper understanding of the influence of fine-scale fuel patterns on fire behavior is essential to the design of forest treatments that aim to reduce fire hazard, enhance structural complexity, and increase ecosystem function and resilience. Of…
Year Published:
Building containment lines and removing fuels can bring wildland firefighters close to advancing flames. In these high-risk situations, firefighters depend on safety zones - large, open areas with little flammable material where they can retreat if…
Year Published:
1. Climate, disturbance, vegetation response, and their interaction are key factors in predicting the distribution and function of ecosystems across landscapes. A range of factors, operating through different pathways, are amplifying the feedbacks…
Year Published:
Background: There has been little quantification of the extent and duration of micrometeorological changes within a forest after airtanker drops of water-based suppressant. It has been speculated that a period of prolonged relative humidity –…
Year Published:
The influence of forest treatments on wildfire effects is challenging to interpret. This is, in part, because the impact forest treatments have on wildfire can be slight and variable across many factors. Effectiveness of a treatment also depends on…
Year Published:
Prescribed fire is a useful tool for building resilient landscapes in fire-prone areas across the globe. In the western U.S., prescribed fire is employed by federal, state, and Tribal land managers and planned during particular meteorological and…
Year Published:
By all measures, wildfires in the western United States are becoming more extreme. Fires are growing larger and burning more intensely, and suppression costs are spiraling upward. Maximizing the effectiveness of fuel treatments at the landscape…
Year Published:
The surge of extreme wildfires around the world, most recently in Canada, provides a frightening glimpse of the potential for intense fires driven by climate change to cause remarkable damage to human and environmental life. From 2019 to 2020,…
Year Published:
Background: Medical services for wildland fire incidents are vital and fire personnel need to be comfortable seeking care and have adequate access to care.
Aims: The aim of this study was to examine wildland firefighters’ (WLFFs) attitudes towards,…
Year Published:
Surface fuel information is an essential input for models of fire behaviour and fire effects. However, spatially explicit, continuous information on surface fuel loads and fuelbed depth is scarce because the collection of field data is laborious,…
