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…

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…
Year Published:
Background: Fires can alter soil properties via downward heat transfer. Numerous studies have examined effects of wildfires and prescribed burns on soils, yet knowledge of the soil temperatures and durations reached is limited. This can lead to…
Year Published:
This study investigated the speciation and aqueous dissolution of macronutrients in fire ash from diverse ecosystems and speciation of ash and smoke from laboratory burning, exploring the variations and their causes. The speciation of phosphorus (P…
Year Published:
The interfacial properties of the organic fraction of biomass burning aerosols (BBA), such as the critical micelle concentration (CMC) and surfactant composition, may vary based on the origin and moisture content of the fuel and the resulting…
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…

Significance
Highly destructive wildfires are occurring more frequently across the globe, prompting debates over the causes for this increase and effective management responses. We investigated building destruction trends in the United States by…
Year Published:
Successive catastrophic wildfire seasons in western North America have escalated the urgency around reducing fire risk to communities and ecosystems. In historically frequent-fire forests, fuel buildup as a result of fire exclusion is contributing…
Year Published:
Prescribed fire has emerged as an essential ecosystem management practice for maintaining forest health and mitigating wildfire risks. However, its spatio-temporal patterns and potential impacts on water quantity and quality remain poorly understood…
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:
Problem statementIn the western United States, human activities have accounted for 63% of wildfire ignitions in recent decades, and tend to occur in different locations and seasons than lightning-caused wildfires. There is increasing need to…

We evaluated over 2200 fires that have burned within the NWFP area.
•
Area burned and high severity patch size increased in both moist and dry forests.
•
We observed large-scale erosion of forest cover in late successional reserves.

Highlights
Douglas-fir seedling recovery varies with burn severity and salvage logging.
Salvage logging lowers biomass in high severity sites with already sufficient light.
Water stress increases with severity and salvage, yet biomass remains high…

Background
Vegetation, terrain and weather properties vary greatly spatially and temporally, all of which influence fire behavior.
Aims
This study aims to enhance the applicability and predictive accuracy of the Rothermel model for mixed fuel spread…
Year Published:
Background
Increasing wildfire area burned has left millions of hectares in the western United States (US) in need of reforestation. Recent federal legislation allows for increased investments in tree planting to address the backlog of planting…
Year Published:
Fuels treatments intended to reduce fuel loads and improve forest health on public lands offer one way to reduce wildfire hazards in the wildland-urban interface (WUI), where the natural and built environments meet. However, for fuels treatment…

Significance
Wildfire activity has increased dramatically in the western United States over the last three decades, leading to a significant impact on air quality and human health. This study highlights the substantial role of anthropogenic climate…
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…
