Abstract
Background
United States wilderness areas face increasing challenges from altered fire regimes and climate change, and land managers face ever more complex decisions about fire use. While federal policies permit various fire management…

The International Association of Wildland Fire has committed to promoting health and wellbeing for wildland fire practitioners, their families and support communities.
The IAWF board has approved a position paper titled IAWF Position Statement:…

Rangeland fires can quickly change the structure of wildlife habitat and cause changes that persist for years to decades. To facilitate habitat recovery, postfire restoration actions often involve sowing seeds of native and nonnative perennial…

Wildfires are a source of air pollution, which impacts air quality in proximity to and at great distances from fires. Wildfire smoke exposure is seasonal and episodic, with exposure levels and durations that can vary considerably. Exposure to…

Highlights
•
DAP and lidar were evaluated for modeling fire effects.
•
DAP augmented with Sentinel-2 approached the performance of lidar.
•
Lidar and DAP heights exhibit weaker correlations as lidar cover decreases.
•
DAP struggled in high…

Background: Drought, human disturbance, and invasive species are reshaping disturbance regimes and increasing the scale, severity, and frequency of wildfire in many ecosystems around the globe, including the sagebrush steppe of western North America…
Year Published:
Forest managers are faced with escalating size, severity, and cost of wildfires. To mitigate this, U.S. federal land management agencies are increasing forest treatments such as mechanical thinning and prescribed fire. While there is a growing body…

This paper numerically investigates the effects of ambient wind and sloped terrains on the behavior of moving fire whirls using Fire Dynamics Simulator (6.7.6). Five configurations were designed, including small- and large-scale L-shaped fire…
Year Published:
Fire regimes are shifting around the world due to climate and land-use change, resulting in an increased frequency of large and severe wildfires. However, the impact of extreme wildfire events on animal species remains poorly understood.…
Year Published:
Forest fires not only destroy vegetation and directly decrease forested areas, but they also significantly impair forest stand structures and habitat conditions, ultimately leading to imbalances within the entire forest ecosystem. Therefore,…
Year Published:
Tree phenotypes vary because of genotype–climate interactions, and this variation influences host selection by tree-killing bark beetles. As climate-driven bark beetle outbreaks intensify, identifying phenotypic traits that best predict resistance…
Year Published:
Volunteer firefighters often have lower cardiorespiratory fitness (CRF) and less access to health monitoring and fitness programs than career firefighters, yet few studies explore how individual and departmental factors influence their CRF. This…
Year Published:
Altered fire regimes and post-fire tree regeneration failures have the potential to drive forest cover losses throughout western North America, but management practices such as active reforestation may help address these challenges. Planting of…
