The biogeochemical signature of fire shapes the functioning of many ecosystems. Fire changes nutrient cycles not only by volatilizing plant material, but also by altering organic matter decomposition—a process regulated by soil extracellular enzyme…
Year Published:
Postfire recovery of fire-adapted forests remains uncertain as climate and fire regimes continue to change. Areas of poor postfire tree regeneration following late-20th-century fires may reveal characteristics associated with increased vulnerability…
Year Published:
Smouldering peat fires are responsible for regional haze episodes and cause environmental, social and health crises. Owing to the unique burning characteristics of smouldering peat, identifying and detecting this kind of fire remains a challenge.…

Almost half of all Americans (45 percent) reported that their lives were affected a lot by COVID-19 pandemic conditions in 2020 and experienced a lot of worry and stress on a daily basis (Gallup, Inc. 2021). Nevertheless, even more said that they…

We examined the financial efficiency and effectiveness of landscape versus community protection fuel treatments to reduce structure exposure and loss to wildfire on a large fire-prone area of central Idaho (USA). The study area contained 63,707…

Negative imagery of destruction may induce or inhibit action to reduce risks from climate-exacerbated hazards, such as wildfires. This has generated conflicting assumptions among experts who communicate with homeowners: half of surveyed wildfire…
Year Published:
The fire-exotic annual grass cycle is a severe threat to shrub-steppe rangelands, and a greater understanding of how livestock grazing relates to the problem is needed to guide effective management interventions. Grazing effects vary throughout…
Year Published:
Cairpol and Aeroqual air quality sensors measuring CO, CO2, NO2, and other species were tested on fresh biomass burning plumes in field and laboratory environments. We evaluated the sensors by comparing 1 min sensor measurements to collocated…
Year Published:
Firebrand piles are known to ignite combustible infrastructure resulting in significant damage; however, the parameters that impact the heat transfer from firebrand piles to a combustible surface are not well understood. Heat transfer from a…

Accurate assessment of burn severity is a critical need for an improved understanding of fire behavior and ecology and effective post-fire management. Although NASA Landsat satellites have a long history of use for remotely sensed mapping of burn…
Year Published:
The number and size of wildfires in the western United States have increased dramatically in the last 30 years. The rising cost of wildfire suppression has become a significant concern for all levels of government, although most attention has been…
Year Published:
Forests mitigate climate change by sequestering massive amounts of carbon, but recent increases in wildfire activity are threatening carbon storage. Currently, our understanding of wildfire impacts on forest resilience and the mechanisms controlling…
Year Published:
Wildfires are a perennial event globally, and the biogeochemical underpinnings of soil responses at relevant spatial and temporal scales are unclear. Soil biogeochemical processes regulate plant growth and nutrient losses that affect water quality,…

Remotely piloted aircraft systems (RPAS) are providing fresh perspectives for the remote sensing of fire. One opportunity is mapping tree crown scorch following fires, which can support science and management. This proof-of-concept shows that crown…
Year Published:
Native American and Alaska Native tribes manage millions of acres of land and are leaders in forestry and fire management practices despite inadequate and inequitable funding. Native American tribes are rarely considered as research partners due to…
Year Published:
Active forest restoration programs on western US national forests face multiple challenges to meet their broad ecological goals while designing projects that generate sufficient revenue to build and maintain private forest management capacity needed…
Year Published:
Over the past several decades, the management of historically frequent-fire forests in the western U.S. has received significant attention due to the linked ecological and social risks posed by the increased occurrence of large, contiguous patches…

Purpose of Review
Fire and insects are major disturbances in North American forests. We reviewed literature on the effects of fire on bark beetles, defoliators, and pollinators, as well as on the effects of bark beetle and defoliator epidemics on…
Year Published:
Managing wildfire risk across boundaries and scales is critical in fire-prone landscapes around the world, as a variety of actors undertake mitigation and response activities according to jurisdictional, conceptual and administrative boundaries,…
Year Published:
The current study presents a series of experiments investigating the smoldering behavior of woody fuel arrays at various porosities under the influence of wind. Wildland fuels are simulated using wooden cribs burned inside a bench scale wind tunnel…
