Fire-prone dry forests often face increasing fires from climate change with low resistance and resilience due to logging of large, old fire-resistant trees. Their restoration across large landscapes is constrained by limited mature trees, physical…

Fires, among other forms of natural and anthropogenic disturbance, play a central role in regulating the location, composition and biomass of forests. Understanding the role of fire in global forest loss is crucial in constraining land‐use change…

Complexity is the main feature of many fire-prone environments, in which the fire regime is driven by climate and socio-economic development on short and long timescales. In this study, the interaction between social and forest environments is…

Traditional fire smoke detection methods mostly rely on manual algorithm extraction and sensor detection; however, these methods are slow and expensive to achieve discrimination. We proposed an improved convolutional neural network (CNN) to achieve…

Aim: Pyrodiversity is the spatial or temporal variability in fire effects across a land- scape. Multiple ecological hypotheses, when applied to the context of post- fire sys- tems, suggest that high pyrodiversity will lead to high biodiversity. This…

The globe is struggling with concurrent planetary health emergencies: COVID-19 and wildfires worsened by human activity. Unfortunately, a lack of awareness of climate change as a health issue, as well as of the interconnections between biodiversity…

The world´s forests are one of the largest carbon sinks, making a substantial contribution to counterbalance the increase in atmospheric carbon from anthropogenic sources (Bastin et al., 2019). For this reason, there is broad support to forest…

To support improved wildfire incident decision-making, in 2017 the US Forest Service (Forest Service) implemented risk-informed tools and processes, together known as Risk Management Assistance (RMA). The Forest Service is developing tools such as…
Year Published:
Recent extreme wildfire seasons in the United States (US) have rekindled policy debates about the underlying drivers and potential role forest management can play in reducing fuels and future wildfire. Most US western national forests face a…

Increasing drought and changing temperatures drive researchers to seek more efficient and effective means to aid management of coniferous forests across the western United States. Thinning allows for effective removal of biomass, but with few…

Fire spread occurs via radiation, flame contact, and firebrands. While firebrand showers are known to be a cause of spot fires which ignite fuels far from the main fire front, in the case of short distance spot fires, radiation from the main fire…

Context:Landscape and local factors govern tree regeneration across heterogeneous post-fire forest environments. But their relative influence is unclear—limiting the degree that managers can consider landscape context when delegating resources to…
Year Published:
National forests in the western United States are divided roughly in half between lands without roads managed for wilderness characteristics and lands with an extensive road system managed for multiple uses including resource extraction. We…

Objective:To identify physiologic stressors related to cardiovascular disease via changes in metabolic, inflammatory, and oxidative stress biomarkers during 2 weeks of preseason training in wildland firefighters (WLFFs).
Methods:Participants were…

Forest residues and logging slash from pre-commercial forest thinning and regeneration harvests are a potential feedstock for bioenergy production but there has been a concern about the impact of residue removal on forest soil C and N. This study…
Year Published:
North American forests are threatened by changes in climate and disturbance dynamics. Current efforts to model future vegetation and fire dynamics are challenged by the lack of mechanistic representation of ecological processes, the spatial…
Year Published:
Recent fire seasons brought a new fire reality to the western US, and motivated federal agencies to explore scenarios for augmenting current fuel management and forest restoration in areas where fires might threaten critical resources and developed…

For over 100 years, the US Forest Service (USFS) has developed initiatives to improve safety outcomes. Herein we discuss the engineered solutions used from 1910 through 1994, when the agency relied on physical science to address the hazards of…

Climate change is projected to exacerbate the intensity of heat-waves and drought, leading to greater incidences of large and high-intensity wildfires in forested ecosystems. While commonly-used remotely-sensed spectral assessments can provide…
