Background: Roads play an important role in managing fire on the national forests. But roads also are known to increase ignitions and damage ecosystems. Roads may limit the size of wildfires, which may be viewed as desirable where fires endanger…
Year Published:
Wildfires have increasingly affected human and natural systems across the western United States (WUS) in recent decades. Given that the majority of ignitions are human-caused and potentially preventable, improving the ability to predict fire…
Year Published:
As climate conditions intensify fire seasons, human exposure to wildfire smoke becomes a more significant concern, posing health risks and disrupting emotional and social well-being. Academic literature exploring how people perceive and respond to…
Year Published:
Multi-stakeholder planning and prioritization for ecosystem management and wildfire risk mitigation are complicated by the need to balance a multitude of values, goals, viewpoints, and interests across large landscapes. Doing so requires quantifying…

This fact sheet on wildfire smoke from the Montrose Lab at Colorado State University synthesizes information about wildfire smoke composition, health impacts to wildland firefighters, mitigation methods, and health resources that are available for…

Aerial retardant drops are widely used in wildfire suppression, yet their effectiveness in slowing fire spread remains difficult to quantify at scale. This study evaluates their impact on wildfire rate of spread (ROS) using a framework that combines…

Project Overview
Wildfires are increasing in both size and frequency in sagebrush (Artemisia spp.) shrublands in the Great Basin, USA, threatening valued property and native vegetation that contribute to regional economies, and provide habitat for…

Background
Wildland fuels are fundamental variables in modeled predictions of fire behavior and effects. In forest ecosystems, accumulated forest floor layers, including recently fallen litter and highly decomposed organic material (i.e., duff),…
Year Published:
Extreme wildfires are escalating in frequency and intensity as climate change, land abandonment, and decades of fire suppression create landscapes primed to burn. Yet wildfire management remains largely absent from the global nature-based solutions…
Year Published:
Forest fires present significant global risks, leading to loss of life, community displacement, and extensive damage to property and the environment, with substantial economic and social consequences. Propagation of wildland fires can be divided…
Year Published:
Spot-fire generation from embers blown ahead of a wildfire front is one of the leading causes of home destruction in wildland-urban interface (WUI) fires. It is, therefore, important to be able to model wind-driven ember flight accurately. This…
Year Published:
Background: Despite progress in reducing industrial air pollution, rising wildfire frequency and intensity, driven in part by climate change, pose significant health risks. Accurate estimates of wildfire-generated fine particulate matter with an…
Year Published:
The intensity of wildfires is projected to increase with the rising frequency of droughts due to climate change. Management practices following forest fires must include restoring the appropriate species composition. This study was performed within…
Year Published:
Lightning is the primary natural cause of wildfires in mid- to high-latitude forests, and it is increasing in frequency under climate change. Traditional fire danger forecasts, reliant on standard meteorological data, often fail to capture extreme…
Year Published:
Biological legacies (i.e., materials that persist following disturbance; “legacies”) shape ecosystem functioning and feedbacks to future disturbances, yet how legacies are driven by pre-disturbance ecosystem state and disturbance severity is poorly…
Year Published:
Wildfires are crucial in shaping forest ecosystems globally, influencing structure, biodiversity, and ecosystem services. However, the interaction of climate change, reduced grazing, fuel accumulation, and human-caused ignitions has led to a…
Year Published:
This literature review synthesizes recent research on use of stable isotopes to advance forest ecosystem management. Stable isotopes provide insights into soil fertility, nutrient cycling, climate variability, and pollution impacts by tracing carbon…
Year Published:
Elevated soil temperatures resulting from reintroduction of prescribed fire into long unburnt stands have been associated with unintended tree mortality. Several models exist to predict soil temperatures resulting from soil heating by fire; however…
