The Forest Vegetation Simulator (FVS) growth and yield model is widely used throughout the United States, but recent studies have reported unexpectedly large bias for some regional model variants. Here we propose a general framework for model…

Background: Fire strongly affects animals’ behavior, population dynamics, and environmental surroundings, which in turn are likely to affect their immune systems and exposure to pathogens. However, little work has yet been conducted on the effects…
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…

The 2020 fire season in the western United States (the West) has been staggering: over 2.5 million ha have burned as of 31 September, including over 1.5 million ha in California (3.7% of the state), in part from five of the six largest fires in…

Aerial Thermal Infrared (TIR) imagery has demonstrated tremendous potential to monitor active forest fires and acquire detailed information about fire behavior. However, aerial video is usually unstable and requires inter-frame registration before…
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:
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…
Year Published:
As anthropogenic emissions continue to decline and emissions from landscape (wild, prescribed, and agricultural) fires increase across the coming century, the relative importance of landscape-fire smoke on air quality and health in the United States…
Year Published:
PM2.5 is the most monitored air pollutant for which EPA has set national ambient air quality standards (NAAQS). As such, it is the pollutant on which the Air Quality Index (AQI) is most often based. PM2.5 and PM10 are the only criteria pollutant…
Year Published:
The evaluation of the effect of burn severity on forest soils is essential to determine the impact of wildfires on a range of key ecological processes, such as nutrient cycling and vegetation recovery. The main objective of this study was to assess…
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…
Year Published:
Humans have both intentional and unintentional impacts on their environment, yet identifying the enduring ecological legacies of past small-scale societies remains difficult, and as such, evidence is sparse. The present study found evidence of an…
Year Published:
Wildland firefighters are repeatedly exposed to elevated levels of wildland fire smoke (WFS) while protecting lives and properties from wildland fires. Studies reporting personal exposure concentrations of air pollutants in WFS during fire…
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:
The dead foliage of scorched crowns is one of the most conspicuous signatures of wildland fires. Globally, crown scorch from fires in savannas, woodlands, and forests causes tree stress and death across diverse taxa. The term crown scorch, however,…
Year Published:
US fire scientists are developing Potential Wildfire Operational Delineations, also known as ‘PODs’, as a pre-fire season planning tool to promote safe and effective wildland fire response, strengthen risk management approaches in fire management…
Year Published:
Background: Bats are important components of forested ecosystems and are found in forests worldwide. Consequently, they often interact with fire. Previous reviews of the effects of fire on bats have focused on prescribed fire effects, in part due to…
Year Published:
The acute stress response is a cornerstone of animal behavior research, but little is currently understood about how responses to acute stressors (i.e. discrete noxious stimuli) may be altered in future climates. As climate change ensues, animals…
Year Published:
Recent wildfires in the western United States have led to substantial economic losses and social stresses. There is a great concern that the new climatic state may further increase the intensity, duration, and frequency of wildfires. To examine…
Year Published:
The year 2020 brought unimaginable challenges in public health, with the confluence of the COVID-19 pandemic and wildfires across the western United States. Wildfires produce high levels of fine particulate matter (PM2.5). Recent studies reported…
