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…

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:
In response to large, severe wildfires across the western US, federal initiatives have been enacted to increase the pace, scale, and quality of ecological restoration in fire dependent forests. To address uncertainty and controversy in agreement…
Year Published:
As wildfires in the western United States continue to increase in size and number due to historical fire suppression and climate change, it is imperative for people living in fire-prone areas to “live with fire.” Fire suppression efforts are…
Year Published:
Tree mortality associated with drought and concurrent bark beetle outbreaks is expected to increase with further climate change.When these two types of disturbance occur in concert it complicates our ability to accurately predict future forest…
Year Published:
Climate change in concert with fire suppression is increasing the size, severity and frequency of fires globally. At the same time, insects, an exceptionally biodiverse group that provide essential ecosystem services such as pollination and…

Firebrands are a widely observed phenomenon in wildland fires, which can transport for a long distance, cause spot ignition in the wildland–urban interface (WUI) and increase the rate of wildfire spread. The flame attached to a moving firebrand…
Year Published:
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…
Year Published:
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:
Smoke, as a prominent character of combustion, is widely regarded as a signal of forest fire. Existing in a video-based smoke root detection methods on rely the distance between smoke and the lens, which is one of the most challenging parts. In…
Year Published:
Recent increases in destructive wildfires are driving a need for empirical research documenting factors that contribute to structure loss. Existing studies show that fire risk is complex and varies geographically, and the role of vegetation has been…
Year Published:
The advancement of three-dimensional, time-dependent fire behaviour models is best supported by publicly available, co-located, synchronised, quality-assured measures of pre-fire, active fire and post-fire conditions (i.e. integrated datasets).…
Year Published:
Great Basin shrublands in the United States are rapidly converting to annual grass- dominated ecosystems, driven primarily by increased wildfire activity. Post-fire vegetation recovery trajectories vary spatially and temporally and are influenced by…
Year Published:
Ventenata (Ventenata dubia L.) is an invasive annual grass that has rapidly expanded its range across temperate grassland and shrub-steppe ecosystems in western North America. However, there is little published regarding its ecology, especially its…
