Recently burned boreal forests have lower aboveground fuel loads, generating a negative feedback to subsequent wildfires. Despite this feedback, short-interval reburns (≤20 years between fires) are possible under extreme weather conditions. Reburns…

Wildfire activity is increasing globally. The resulting smoke plumes can travel hundreds to thousands of kilometers, reflecting or scattering sunlight and depositing particles within ecosystems. Several key physical, chemical, and biological…

Background: Understory flammability is affected by abscised plant tissue. Extensive research has shown how interspecific differences in leaf litter traits affect flammability; however, leaves represent only one component of the litter layer. Cones…

Fire-adapted dry forests and nearby communities both need to be sustained as climate changes. Wildfires have increased in the ~25.5 million ha of dry forests in the western US, but are wildfires already more severe than historical (preindustrial)…

Wildfires directly emit 2.1 Pg carbon (C) to the atmosphere annually. The net effect of wildfires on the C cycle, however, involves many interacting source and sink processes beyond these emissions from combustion. Among those, the role of post-fire…
Year Published:
Prescribed burning is a key management strategy within fire-adapted systems, and improved monitoring approaches are needed to evaluate its effectiveness in achieving social-ecological outcomes. Remote sensing provides opportunities to analyse the…
Year Published:
Increasing frequency of droughts and wildfire are sparking concerns that these compounded disturbance events are pushing forested ecosystems beyond recovery. An improved understanding of how compounded events affect tree physiology and mortality is…
Year Published:
Expected future scenarios including climate change, a greater incidence of urban conflagrations, and continued fuel-load accumulations will increase demands on the wildfire management system in the United States, resulting in increased difficulty…

This data publication contains tree and nonstructural carbohydrate (NSC) (soluble sugars, starch) data from an investigation of how fire affects NSCs based on fire-caused injury from a prescribed fire in a young ponderosa pine (Pinus ponderosa…
Year Published:
Large and downed woody fuels remaining behind a wildfire’s flame front tend to burn in a smoldering regime, producing large quantities of toxic gases and particulate emissions, which deteriorates air quality and compromises human health. Smoldering…

The 2021 Tamarack Fire in California, started by lightning in a national forest wilderness area, burned nearly 70,000 acres and eventually destroyed 24 structures. Because properties were damaged, the public and media scrutinized the fire management…
Year Published:
Managers increasingly seek to increase forest soil carbon but long-term controls on soil organic matter (SOM) sources and stability are weakly understood. We used a 30-year detrital input/removal treatment experiment in a deciduous forest to…

Background: Increased use of visualizations as wildfire communication tools with public and professional audiences-particularly 3D videos and virtual or augmented reality-invites discussion of their ethical use in varied social and temporal contexts…
Year Published:
The goal of the present work is to establish a framework for firebrand morphology characterization. Central to this framework is the development of a simple firebrand shape classification model using multi-dimensional particle shape descriptors.…
Year Published:
Boreal forests are frequently subjected to disturbances, including wildfire and clear-cutting. While these disturbances can cause soil carbon (C) losses, the long-term accumulation dynamics of soil C stocks during subsequent stand development is…
Year Published:
Satellite remote sensing plays a significant role in the detection of smoke from forest fires. However, existing methods for detecting smoke from forest fires based on remote sensing images rely solely on the information provided by the images,…
Year Published:
Black greasewood (Sarcobatus vermiculatus Hook., Torr) is a native halophytic, resprouting shrub found on saline rangeland soils in the western United States, including the western Great Plains grasslands. Stands can become dense, with limited…

Ecosystems are frequently disturbed by fires that have an important impact on the soil environment and the composition of soil organisms. In order to provide a baseline for the current research and identify trends on the effects of wildland fire on…
Year Published:
Wildland fire dispatchers play a key role in wildland fire management and response organization; however, to date, wildland fire studies have largely focused on the physical hazards and, to a lesser extent, mental health hazards of wildland…

A study was carried out to investigate the effects of wildfires on lake water quality using a source dataset of 2024 lakes worldwide, covering different lake types and ecological settings. Satellite-derived datasets (Lakes_cci and Fire_cci) were…
