The ecosystem response to fire is often linked to fire severity and recurrence, with potentially larges consequences on both above- and below-ground processes. Understanding the fire impact has become increasing important in the light of recent…

The fuel packing ratio () significantly influences the fire spread in discrete fuels; however, the underlying mechanism remains unclear. This study performed experiments using laser-cut cardboards with different packing ratios to explore the heat…
Year Published:
North American forests are threatened by changes in climate and disturbance dynamics. Current efforts to model future vegetation and fire dynamics are challenged by the lack of mechanistic representation of ecological processes, the spatial…
Year Published:
After natural forest disturbances such as wildfires, windstorms and insect outbreaks, salvage logging is commonly applied to reduce economic losses and mitigate subsequent disturbance risk. However, this practice is controversial due to its…
Year Published:
Wildfires were a frequent source of disturbance in forests of the Western United States prior to Euro-American settlement. Following a series of catastrophic wildfires in the Northern Rockies in 1910, the U.S. Forest Service adopted a broad wildfire…
Year Published:
While western U.S. wildfires have increased in intensity and scale, their impacts on soil chemical composition and hydraulic processes have received little attention, despite increasing erosion, surface runoff and flooding. The relationships between…
Year Published:
Private landowners are important actors in landscape-level wildfire risk management. Accordingly, wildfire programs and policy encourage wildland–urban interface homeowners to engage with local organizations to properly mitigate wildfire risk on…
Year Published:
Wildland fire management across the US is under intense scrutiny as it faces challenges of extreme wildfire seasons, a warming climate and increasing pressures on natural resources. As he ends his term as President of the Student Association for…
Year Published:
Wildland fires (WLF) have become more frequent, larger, and severe with greater impacts to society and ecosystems and dramatic increases in firefighting costs. Forests throughout the range of ponderosa pine in Oregon and Washington are jeopardized…
Year Published:
Question: Northern peatlands are increasingly threatened by wildfire. Severe peatland wildfires can provide opportunities for new non-peatland species to colonise post-fire. Changes in plant colonisation could lead to longer-term shifts in community…
Year Published:
Tower-mounted camera-based wildfire detection systems provide an effective means of early forest fire detection. Historically, tower sites have been identified by foresters and locals with intimate knowledge of the terrain and without the aid of…
Year Published:
Wildfires present an increasing threat to communities through impacts that include destruction of homes or outbuildings, evacuations, damage to public infrastructure, and economic disruption. Effective fire management entails identifying and…
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:
Airborne fine particulate matter (PM2.5) represents the greatest ambient air pollution risk to health. Wildfires and managed burns, together referred to hereafter as ‘landscape’ fires, are a significant PM2.5 source in many regions worldwide, able…
Year Published:
A methodology to quantify uncertainty in wildfire forecast using coupled fire-atmosphere computational models is presented. In these models, an atmospheric solver is coupled with a fire-spread module. In order to maintain a low computational cost,…
Year Published:
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…
Year Published:
Determining whether forest landscapes can maintain their resilience to fire – that is, their ability to rebound and sustain – given rapid climate change and increasing fire activity is a pressing challenge throughout the American West. Many western…
Year Published:
Wildfire is a major driver of nitrogen (N) cycling and export from terrestrial to aquatic systems. While fire is a natural process in many watersheds, it can still degrade water quality by rapidly flushing N to streams. This can be particularly…
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:
Climate change is expected to increase fire activity in many regions of the globe, but the relative role of human vs. lightning-caused ignitions on future fire regimes is unclear. We developed statistical models that account for the spatiotemporal…
