A long-term study at Lick Creek demonstrates how fuel treatments in dry forests provide benefits beyond mitigating the chance of a high-severity fire.

Wildfires are a critical phenomenon in terrestrial ecosystems, and the intensity and frequency of these events have increased in recent years. High temperatures in the topsoil during wildfires can induce changes in soil physical, chemical, and…

Background:Every year thousands of wildland firefighters (WFFs) work to suppress wildfires to protect public safety, health, and property. Although much effort has been put toward mitigating air pollutant exposures for the public and WFFs, the…

Fire is a powerful environmental disturbance with the ability to shape many biomes worldwide. However, global warming, land-use changes and other anthropogenic factors have strongly altered natural fire regimes worldwide. Despite the growing number…

Common land-surface disturbances in rangelands with potential to influence the resistance and resilience of the ecosystem include livestock grazing and fire. The impact of these land-use disturbances on the soil microbial community is important to…
Year Published:
Fires, among other forms of natural and anthropogenic disturbance, play a central role in regulating the location, composition and biomass of forests. Understanding the role of fire in global forest loss is crucial in constraining land‐use change…
Year Published:
Pyrodiversity – spatiotemporal variation of characteristics within a fire regime – plays an important role in structuring wildlife communities after fire, yet there is a need to better incorporate pyrodiversity into predictive models of animal…
Year Published:
Non‐native, invasive Bromus tectorum (cheatgrass) is pervasive in sagebrush ecosystems in the Great Basin ecoregion of the western United States, competing with native plants and promoting more frequent fires. As a result, cheatgrass invasion likely…
Year Published:
Aim: Pyrodiversity is the spatial or temporal variability in fire effects across a land- scape. Multiple ecological hypotheses, when applied to the context of post- fire sys- tems, suggest that high pyrodiversity will lead to high biodiversity. This…

The impacts of wildfires on the health of children are becoming a more urgent matter as wildfires become more frequent, intense and affecting, not only forested areas, but also urban locations. It is important that medical professionals be prepared…

A recent numerical simulation study by Moinuddin et al. (2018) determined that over a specific range of Froude numbers defined by them as ‘plume mode’, grass fuel height has a strong inverse effect on the rate of fire spread in grasslands. They then…

There is demand for greater understanding concerning the impacts of forest management practices on water and sediment yield in the mountainous watersheds of the Pacific Northwest. Common forest operations such as harvesting and road construction can…

The world´s forests are one of the largest carbon sinks, making a substantial contribution to counterbalance the increase in atmospheric carbon from anthropogenic sources (Bastin et al., 2019). For this reason, there is broad support to forest…

Heat accumulation from wearing personal protective equipment can result in the development of heat-related illnesses. This study aimed to investigate factors of heat stress with and without a US standard issue wildland firefighter helmet. Ten male…
Year Published:
Understanding tree physiological responses to fire is needed to accurately model post‐fire carbon processes and inform management decisions. Given trees can die immediately or at extended time periods after fire, we combined two experiments to…
Year Published:
Increasing drought and changing temperatures drive researchers to seek more efficient and effective means to aid management of coniferous forests across the western United States. Thinning allows for effective removal of biomass, but with few…

Fire spread occurs via radiation, flame contact, and firebrands. While firebrand showers are known to be a cause of spot fires which ignite fuels far from the main fire front, in the case of short distance spot fires, radiation from the main fire…
Year Published:
National forests in the western United States are divided roughly in half between lands without roads managed for wilderness characteristics and lands with an extensive road system managed for multiple uses including resource extraction. We…
Year Published:
The idea that not all fire regimes are created equal is a central theme in fire research and conservation. Fire frequency (i.e., temporal scale) is likely the most studied fire regime attribute as it relates to conservation of fireadapted ecosystems…
Year Published:
Runoff and erosion processes can increase after wildfire and post‐fire salvage logging, but little is known about the specific effects of soil compaction and surface cover after post‐fire salvage logging activities on these processes. We carried out…
