As wildfires in the western United States continue to increase in size and number due to historical fire suppression and climate change, it is imperative for people living in fire-prone areas to “live with fire.” Fire suppression efforts are…

Wildfire disasters on overhead transmission lines seriously threaten the safe and stable operation of large power grids and the normal use of electricity. After a wildfire occurs near a transmission line, it is often inefficient to take measures…
Year Published:
Forests rely on processes like seed dispersal from seed sources (live trees containing mature cones) to jumpstart post-fire tree regeneration. Consequently, managers often estimate the potential for seed dispersal when anticipating whether a burn…

Extreme wildfires are increasing in frequency globally, prompting new efforts to mitigate risk. The ecological appropriateness of risk mitigation strategies, however, depends on what factors are driving these increases. While regional syntheses…
Year Published:
Fire-prone dry forests often face increasing fires from climate change with low resistance and resilience due to logging of large, old fire-resistant trees. Their restoration across large landscapes is constrained by limited mature trees, physical…
Year Published:
Fire severity is a key driver shaping the ecological structure and function of North American boreal ecosystems, a biome dominated by large, high-intensity wildfires. Satellite-derived burn severity maps have been an important tool in these remote…
Year Published:
A simple, easy-to-evaluate, surrogate model was developed for predicting the particle emission source term in wildfire simulations. In creating this model, we conceptualized wildfire as a series of flamelets, and using this concept of flamelets, we…

Wildfires are exorbitantly cataclysmic disasters that lead to the destruction of forest cover, wildlife, land resources, human assets, reduced soil fertility and global warming. Every year wildfires wreck havoc across the globe. Therefore, there is…
Year Published:
Fire exclusion has dramatically altered historically fire adapted forests across western North America. In response, forest managers reduce forest fuels with mechanical thinning and/or prescribed burning to alter fire behavior, with additional…
Year Published:
Shifting fire regimes are substantially changing North American forests. It is thus critical to understand how wildfires affect forest wildlife, especially for species managed for harvest and for species at risk of extinction. In particular, many…

Inhaling wildfire smoke can be harmful, but smoke from unintended wildfires may be worse than smoke from prescribed burns, according to a study published in 2019. That means the health risks from wildfires — like the ones that have destroyed…
Year Published:
Accumulation of dead woody material is a critical management concern following wildfires, especially given the possibility of subsequent wildfires. Forest structure and fuel accumulation are largely driven by site climatic conditions, so variability…

Using observations and model simulations (ESM 4.1) during 1988–2018, we show large year‐to‐year variability in western U.S. PM2.5 pollution caused by regional and distant fires. Widespread wildfires, combined with stagnation, caused summer PM2.5…

[from the text] The danger of catastrophic wildfires is increasing around the globe, with large fires occurring in Australia, Canada, Chile, Indonesia, Portugal, Russia, as well as in the United States over the past decade. A major driver globally…

Background: Wildfires affect vegetation structure, functions, and other attributes of forest ecosystems. Among these attributes, bird assemblages may be influenced by the distance from undisturbed to fire-disturbed forests. Information about this…

As wildfire seasons have expanded in duration and intensity, the effort and dedication required of wildland firefighters have increased (Withen 2015). Firefighters now work from April, when fuels first become available for burning, until well into…
Year Published:
Land treatments in wildland-urban interface (WUI) areas are highly visible and subject to public scrutiny and possible opposition. This study examines a contested vegetation treatment-Forsythe II-in a WUI area of the Arapaho-Roosevelt National…
Year Published:
Monte Carlo simulations using wildland fire spread models have been conducted to produce numerical estimates of fire likelihood, project potential fire effects, and produce event sets of realistic wildfires (Parisien et al., 2019). The application…

This study provides much needed insight into the development of resistance to disturbance and growth dynamics of overstory trees in response to restoration-based fuel reduction, and will be useful to scientists and managers attempting to better…
Year Published:
Particulate matter with aerodynamic diameter < 2.5 μm (PM2.5) is one of the main pollutants generated in wildfire events with negative impacts on human health. In research involving wildfires and air quality, it is common to use emission models.…
