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…

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…

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,…
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…
Year Published:
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,…

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,…

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…

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…

The occurrence of forest ground smoldering combustion has been increasingly frequent in recent years, resulting in significant emissions that have a detrimental impact on the ecological environment. Current research on smoldering emissions, however…

Background
The invasive annual grass cheatgrass (Bromus tectorum) increases fuel continuity, alters patterns of fire spread, and changes plant communities in sagebrush shrublands of the Great Basin (USA) and adjacent sagebrush steppe, but no studies…
Year Published:
Forests are valuable for a wide variety of reasons, including biodiversity and carbon sequestration and storage. As such, in the U.S., various parties have proposed large-scale forest management efforts to enhance biodiversity conservation and…
Year Published:
Wildland firefighting is physically and mentally demanding. The aerobic capacity of firefighters is important due to the demands of the activity and the associated occupational risks. The main objectives of this study were to identify and…

Background
Prescribed fire is vital for fuel reduction and ecological restoration, but the effectiveness and fine-scale interactions are poorly understood.
Aims
We developed methods for processing uncrewed aircraft systems (UAS) imagery into…

This fire regime synthesis details characteristics of ponderosa pine ecosystems from fire history studies conducted in two ecoregions in New Mexico: the Southern Rockies ecoregion (hereafter, Southern Rocky Mountains) and the Arizona/New Mexico…
Year Published:
Forest fires represent a significant intersection between nature and society, often leading to the loss of natural resources, soil nutrients, and economic opportunities, as well as causing desertification and the displacement of communities.…

Fungi play key roles in the fire-fuel feedbacks that structure ~40% of the Earth's terrestrial ecosystems, yet a general understanding of fungal responses to fire is lacking. While fire and associated stressor effects on fungi vary based on fire…
