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…

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…

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…

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:
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:
Remote sensing techniques are of particular interest for monitoring wildfire effects on soil properties, which may be highly context-dependent in large and heterogeneous burned landscapes. Despite the physical sense of synthetic aperture radar (SAR…

(1) Background: Federal land managers in the US are charged with risk-based decision-making which requires them to know the risk and to direct resources accordingly. Without understanding the specific factors that produce risk, it is difficult to…

Wildfires have become an increasing threat for Mediterranean ecosystems, due to increasing climate change induced wildfire activity and changing land management practises. In addition to the initial risk, wildfires can alter the soil in various ways…
Year Published:
Forested watersheds provide many ecosystem services, such as the filtration of sediment, pollutants, and nutrients, which are increasingly threatened by wildfire. Stream nutrient concentrations often increase following wildfire and can remain…
Year Published:
Background: Virtually every decision within wildland fire management includes substantial ethical dimensions. As pressures increase with ever-growing fires, it is becoming increasingly important to develop tools for assessing and acting on the…

Whitebark pine (Pinus albicaulis Engelm.), a high-elevation five-needle white pine (Genus Pinus, Subgenus Strobus), inhabits the higher mountains of western U.S. and Canada, across about 32.6 million ha (about 80.6 million acres), with 70% of its…

Pollution from wildfires constitutes a growing source of poor air quality globally. To protect health, governments largely rely on citizens to limit their own wildfire smoke exposures, but the effectiveness of this strategy is hard to observe. Using…
Year Published:
Fire location and burning area are essential parameters for estimating fire emissions. However, ground-based fire data (such as fire perimeters from incident reports) are often not available with the timeliness required for real-time forecasting.…

Background
‘Megafire’ is an emerging concept commonly used to describe fires that are extreme in terms of size, behaviour, and/or impacts, but the term’s meaning remains ambiguous.
Approach
We sought to resolve ambiguity surrounding the meaning of ‘…

Researchers and practitioners often emphasize the importance of effective community engagement around forest management projects to address possible barriers to implementation related to a lack of social acceptance. Using qualitative methods, we…
Year Published:
Forest fires are key ecosystem modifiers affecting the biological, chemical, and physical attributes of forest soils. The extent of soil disturbance by fire is largely dependent on fire intensity, duration and recurrence, fuel load, and soil…
Year Published:
Wildland fuels, defined as the combustible biomass of live and dead vegetation, are foundational to fire behavior, ecological effects, and smoke modeling. Along with weather and topography, the composition, structure and condition of wildland fuels…
