Extreme wildfires are increasing in frequency globally, prompting new efforts to mitigate risk. The ecological appropriateness of risk mitigation strategies, however, depends on what factors are driving these increases. While regional syntheses…

The National Cohesive Wildland Fire Management Strategy (hereafter: Cohesive Strategy) mandates the restoration and maintenance of landscapes, with the goal that “landscapes across all jurisdictions are resilient to fire-related disturbances in…
Year Published:
The main purpose of this study was to characterise the thermal environment and risk of heat burns of wildland firefighters in relation to the suppression tasks performed in real wildland fires. Measurements of air temperature and heat flux were…
Year Published:
As wildland fires amplify in size in many regions in the western USA, land and water managers are increasingly concerned about the deleterious effects on drinking water supplies. Consequences of severe wildfires include disturbed soils and areas of…
Year Published:
A key challenge in the United States is how to manage wildfire risk across boundaries and scales, as roles, responsibilities, and ability to act are distributed among actors in ways that do not always incentivize collective action. In this review…

We appreciate Hutto’s call to promote positive ecological outcomes by recognizing diverse forest fire ecologies. Nevertheless, we continue to argue that restoration treatments are appropriate in the approximately 17 million ha of forest in the…

Wildfire activity in the western United States has been increasing since the 1970s, with many fires occurring on land managed by government agencies. Over six million acres of public lands are surrounded by private land and lack road access, making…
Year Published:
Risk management is a significant part of federal wildland fire management in the USA because policy encourages the use of fire to maintain and restore ecosystems while protecting life and property. In this study, patterns of wildfire risk were…

A physics/chemistry-based numerical model for predicting the emission of fine particles from wildfires is proposed. This model implements the fundamental mechanisms of soot formation in a combustion environment: soot nucleation, surface growth,…

im Gumm: I have the privilege of talking to Leslie Weldon and Holly Krake about psychological safety in general and, in particular, an article that Holly led in writing called “The Big Quiet.” Leslie, let’s start with you: What comes to mind when we…

Bark beetle outbreaks and forest fires have imposed severe ecological damage and caused billions of dollars in lost resources in recent decades. The impact of such combined disturbances is projected to become more severe, especially as climate…
Year Published:
Wildland fire management decision-makers need to quickly understand large amounts of quantitative information under stressful conditions. Categorization and visualization 'schemes' have long been used to help, but how they are done affects the speed…
Year Published:
The idea that not all fire regimes are created equal is a central theme in fire research and conservation. Fire frequency (i.e., temporal scale) is likely the most studied fire regime attribute as it relates to conservation of fireadapted ecosystems…
Year Published:
Because fire retardant can enter streams and harm aquatic species including endangered fish, agencies such as the U.S. Forest Service (USFS) must estimate the downstream extent of toxic effects every time fire retardant enters streams (denoted as an…
Year Published:
Widespread fire activity taxes suppression resources and can compound wildfire hazards. We examine the geographic synchronicity of fire danger across western United States forests as a proxy for the strain on fire suppression resource availability.…

Fire behavior is well described by a fire’s direction, rate of spread, and its energy release rate. Fire intensity as defined by Byram (1959) is the most commonly used term describing fire behavior in the wildfire community. It is, however,…

Projected warming of global surface air temperatures will further exacerbate droughts, wildfires, and other agents of ecosystem stress. We use latewood blue intensity from high‐elevation Picea engelmannii to reconstruct late‐summer maximum air…

Questions: Relative to a landscape with a mosaic of two sagebrush community types and increasing fire frequency, we asked: 1) Do vegetation characteristics vary significantly with number of times burned for each sagebrush community? 2) How do…
Year Published:
Increased frequency and new types of disturbances caused by global change calls for deepened insights into possible alterations of successional pathways. Despite current interest in disturbance interactions there is a striking lack of studies…
Year Published:
Western North American fires have been increasing in magnitude and severity over the last few decades. The complex coupling of fires with the atmospheric energy budget and meteorology creates short-term feedbacks on regional weather altering the…
