Highlights
•
Fall prescribed burns combusted more surface soil carbon than spring burns.
•
Fall burns stimulated microbial respiration, slowing soil carbon recovery.
•
Microbial respiration was lower after spring burns, allowing soil C to…

Background
Vegetation fire risk is increasing in temperate regions like the UK, yet understanding of surface and synoptic weather controls on fire is limited.
Aims
We examined seasonal relationships between (i) synoptic weather patterns and surface…

Background
Climate change is expected to alter fire return intervals in cold and wet forests in the northwestern United States. This coupled with an expected rise in prescribed fires to restore healthy forests, disproportionately increases risk to…

Background
Reducing fuels in overly dense, arid forests of the Western US is a prominent fire mitigation strategy. Fuel treatments, including thinning and prescribed burning, are a means of reintroducing fire to fire-dependent forests and…
Year Published:
Bush encroachment into rangelands is a topical issue across the globe, especially in semiarid regions, including southern Africa. Because this has negative implications for livestock production and biodiversity conservation, effective and…
Year Published:
The development of fire-induced wind and its action on wildfire behaviour are studied by numerical simulation of fire spread on sloping terrain. The simulations, conducted using a physics-based fire model, are based on a shrubland fire experiment…

Abstract
Ponderosa pine forests are experiencing large-scale mortality and inadequate natural regeneration across the American Southwest. High-quality nursery-grown ponderosa pine (Pinus ponderosa Douglas ex C. Lawson) seedlings for reforestation…
Year Published:
Thermal radiation from the flame to the unburned fuel plays a key role in horizontal concurrent flame spread by heating the fuel surface and influencing the spread of the flame. This work investigates thermal radiation in horizontal concurrent flame…

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…

Year Published:
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…
Year Published:
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…
Year Published:
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…
