Effective wildfire prevention includes actions to deliberately target different wildfire causes. However, the cause of an increasing number of wildfires is unknown, hindering targeted prevention efforts. We developed a machine learning model of…

Over the last 20 years, all states within the US have required all cigarettes sold to be ‘‘fire safe’’ or ‘‘fire standards compliant’’ meaning that they must pass ASTM standard E2187. Though these cigarettes are designed to self-extinguish, there…

Background
Wildfire simulation models are used to derive maps of burn probability (BP) based on fuels, weather, topography and ignition locations, and BP maps are key components of wildfire risk assessments.
Aims
Few studies have compared BP maps…

Fire and drought are expected to increase in frequency and severity in temperate forests due to climate change. To evaluate whether drought increases the likelihood of post-fire tree mortality, we used a large database of tree survival and mortality…

Background: Terrain-induced turbulence is dangerous for smokejumpers parachuting into complex terrain and results in numerous serious accidents annually.
Aims: We quantify wind modelling system WindNinja’s ability to reproduce terrain-induced…
Year Published:
Increasing wildfire risk in Alaska has prompted the adoption of fuel reduction treatments, including hand-thinning and mechanical mastication, to mitigate fire behavior and improve firefighter safety. This intensification of forest management…
Year Published:
Foliar moisture content (FMC) plays a crucial role in the arid, fire-adapted forests of the western US by influencing fire behavior, tree survival, and serving as a proxy for tree health. Management actions such as mechanical thinning and prescribed…

Wildfire policy has evolved rapidly over the past three decades, necessitating repeated shifts in management and communication strategies for US land management agencies. One growing focus considers the use of “other than full suppression” (OTFS)…

Collaborative efforts are an effective tool for managing the growing social and ecological complexities of wildfire adaptation at the landscape level. However, efforts to document the decision-making processes of collaborative groups around fire…
Year Published:
Background: Modern land management faces unprecedented uncertainty regarding future climates, novel disturbance regimes, and unanticipated ecological feedbacks. Mitigating this uncertainty requires a cohesive landscape management strategy that…
Year Published:
Background: Unprecedented wildfire frequency, fueled by invasive annual grasses, threatens sagebrush ecosystems. To suppress wildfire and conserve sagebrush, land management agencies have installed fuel breaks across the sagebrush biome. However,…

Intensification of drought and wildfire associated with climate change has triggered widespread ecosystem stress and transformation. Natural resource managers are on the frontline of these changes, yet their perspectives on whether management…
Year Published:
Interruption of frequent burning in dry forests across western North America and the continued impacts of anthropogenic climate change have resulted in increases in fire size and severity compared to historical fire regimes. Recent legislation,…
Year Published:
Reforestation activities such as tree planting are important management tools to offset carbon emissions and restore forest ecosystem integrity. Severe wildfire activity, a key driver of forest loss, is increasing throughout the western United…

In western North America, quaking aspen stands (Populus tremuloides Michx.) have predominantly been described as low flammability, “fireproof” forests, but the specific relationship between aspen stand composition, fuel characteristics, and…

Wildfires have become a significant environmental and public health concern worldwide, particularly due to their increased frequency and intensity driven by climate change. Wildfire smoke, composed of a complex mixture of particulate matter, gases…

Many firefighters have inadequate levels of physical fitness which can impair firefighting performance. Understanding the factors that influence exercise and fitness behaviors could help identify those less likely to stay physically fit. Methods: A…

This paper reports on research undertaken for the Building Resilience for Bushfire-Affected Communities in Noosa Shire project, funded by the Australian Government. Being evacuated from a home in the path of a bushfire can be traumatic. Therefore,…

In 2024, wildfires burned a record number of forests participating in California's forest offset program, exposing the danger of relying on forests to slow climate change. While California maintains a reserve of offset credits - known as a “buffer…

Climate change is amplifying both wildfire burned area and severity, as well as incidents of drought-induced tree mortality (dieback). Direct effects from climate change amplify wildfires and episodes of drought-induced dieback have well-known…
