Background: Climate change is a strong contributing factor in the lengthening and intensification of wildfire seasons, with warmer and often drier conditions associated with increasingly severe impacts. Land managers are faced with challenging…
Year Published:
Background: The rising occurrence of simultaneous large wildfires has put strain on United States national fire management capacity leading to increasing reliance on assistance from partner nations abroad. However, limited analysis exists on…
Year Published:
We find that wildfire are part of a distinct temporal pattern of soil moisture, vegetation water content and atmospheric dryness dynamics that begin about 5 months before the incidents. We analyze anomalies in soil moisture, vegetation water content…

Background: Managing landscape fire is a complex challenge because it is simultaneously necessary for, and increasingly poses a risk to, societies and ecosystems worldwide. This challenge underscores the need for transformative change in the way…
Year Published:
Wildland fire incident commanders make wildfire response decisions within an increasingly complex socio-environmental context. Threats to human safety and property, along with public pressures and agency cultures, often lead commanders to emphasize…
Year Published:
Federal agencies responsible for wildland fire management face increasing needs for personnel as fire seasons lengthen and fire size continues to grow, yet federal agencies have struggled to recruit and retain firefighting personnel. While many have…
Year Published:
Background: The decision making process undertaken during wildfire responses is complex and prone to uncertainty. In the US, decisions federal land managers make are influenced by numerous and often competing factors.
Aims: To assess and validate…
Year Published:
The use of masticated tree debris to protect burned soil from post-fire erosion is not common and very little is known about its effectiveness in reducing the risk of erosion after fire. The main objective of this research was to assess the effects…
Year Published:
Background: Potential Wildfire Operational Delineations (PODs) were developed as a pre-season planning tool to promote safe and effective fire response. Past research on PODs has identified uses in an incident management context. There has been…
Year Published:
Standing dead tree stems (snags) become abundant following disturbances like bark beetle outbreaks and stand-replacing fire. Snags are an important element of wildlife habitat, and when they eventually fall can injure or damage people and…
Year Published:
Many nations administer national forest inventory programs for unbiased estimation of forest attributes over broad spatial and temporal extents. However, management and conservation decisions often demand reliable estimates for finer spatiotemporal…
Year Published:
The use of unmanned aerial systems (UAS) by the fire service is becoming more common, especially for large outdoor fires where it is difficult to understand the state of the fire conditions or efficiently suppress the fire. The focus of this paper…
Year Published:
Mulch application following wildfire is increasingly being used to mitigate hillslope runoff and erosion. A mulch coverage of 70% has been proven to be effective in reducing sediment losses; however, most previous studies test only a single slope…
Year Published:
Climate warming, land use change, and altered fire regimes are driving ecological transformations that can have critical effects on Earth's biota. Fire refugia - locations that are burned less frequently or severely than their surroundings - may act…
Year Published:
Background: Burn severity significantly increases the likelihood and volume of post-wildfire debris flows. Pre-fire severity predictions can expedite mitigation efforts because precipitation contributing to these hazards often occurs shortly after…
Year Published:
Fire management aims to change fire regimes. However, the challenge is to provide the optimal balance between the mitigation of risks to life and property, while ensuring a healthy environment and the protection of other key values in any given…
Year Published:
Appropriately designed fuel treatments reduce negative outcomes of wildfire and in some cases promote beneficial wildfire outcomes. Wildfires are a landscape scale phenomenon; therefore, fuel treatments should be evaluated at a landscape level to…
Year Published:
Fire management is growing increasingly complex in an environment beset by climate change, an ever-growing wildland-urban interface, and difficulties developing and maintaining workforce capacity. Delivery of timely and relevant fire science to…
Year Published:
This is a summary from the Selway-Bitterroot and Frank Church-River of No Return Wilderness Fire Science Workshop held June 27-28, 2023. It summarizes discussion points from the first day's breakout groups as well as some key discussion points from…
Year Published:
Interactions between vegetation and sediment in post-fire landscapes play a critical role in sediment connectivity. Prior research has focused on the effects of vegetation removal from hillslopes, but little attention has been paid to the effects of…
