Background
Anthropogenic climate change is expected to catalyze forest conversion to grass and shrublands due to more extreme fire behavior and hotter and drier post-fire conditions. However, field surveys in the Northern Rocky Mountains of the…

In the sentence beginning ‘The first objective of this study’ in this article under Sect. 3.1. Conditions for self-sustained smoldering, quotation marks were added for the x symbol. It should have been read as ‘At a wind speed of 1.5 m/s, some of…

In early 2020 the US Forest Service (USFS) recognized the need to gather real-time information from its wildland fire management personnel about their challenges and adaptations during the unfolding COVID-19 pandemic. The USFS conducted 194 virtual…

The primary objective of prescribed burning (PB) treatment is to promote increased ecosystem resistance to high fire severity and ecosystem adaptive resilience after unplanned wildfires under worsening climates. Yet, empirical evidence involving…

Satellite, radar, and strategically placed Remote Automated Weather Stations (RAWS) are a few of the many technologies used to gather data and predict weather. Yet, some weather events are still unpredictable. A morning forecast for a chance of…

In civil construction, one of the primary challenges associated with wood application is its high flammability and low durability during fires. Although chemical treatment with fire-retardant properties exists, they are expensive and of non-…

Large forest fires have far-reaching impacts on the environment, human health, infrastructure and the economy. Forest fires become large when all forest types across a landscape are dry enough to burn. Mesic forests are the slowest to dry and can…

Fire suppression is the primary management response to wildfires in many areas globally. By removing less-extreme wildfires, this approach ensures that remaining wildfires burn under more extreme conditions. Here, we term this the “suppression bias…

Background
The moisture content of litter and woody debris is a key determinant of fire potential and fire behaviour. Obtaining reliable estimates of the moisture content of dead fine fuels (i.e. 1-h and 10-h fuels) is therefore a critical…
Year Published:
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…

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…

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)…

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:
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…
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…

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…

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.…

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…
