•Wildfires intensify globally; climate change pushes forests beyond recovery.
•
Proactive post-fire management is crucial for future forest adaptation.
•
Resistance-Resilience-Transition framework guides wildfire-affected…
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:
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:
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:
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…
Year Published:
The national Fire and Fire Surrogate (FFS) study was initiated more than two decades ago with the goal of evaluating the ecological impacts of mechanical treatments and prescribed fire in different ecosystems across the United States. Since then, 4…
Year Published:
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.
•

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…

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…
Year Published:
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…
Year Published:
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…
