Wildland fire is a major global driver in the exchange of aerosols between terrestrial environments and the atmosphere. This exchange is commonly quantified using emission factors or the mass of a pollutant emitted per mass of fuel burned. However,…

Background
The record number of wildfires in the United States in recent years has led to an increased focus on developing tools to accurately forecast their impacts at high spatial and temporal resolutions.
Aims
The Warn-on-Forecast System for…

Background
Prescribed fire is a critical tool for building resilience to changing fire regimes. Policymakers can accelerate the development of effective, adaptation-oriented fire governance by learning from other jurisdictions.
Aims
We analyse…

Background: Current guidance for implementation of United States federal wildland fire policy charges agencies with restoring and maintaining fire-adapted ecosystems while limiting the extent of wildfires that threaten life and property, weighed…
Year Published:
Fire has always been an important component of many ecosystems, but anthropogenic global climate change is now altering fire regimes over much of Earth's land surface, spurring a more urgent need to understand the physical, biological, and chemical…
Year Published:
Particulate matter (PM) is a major primary pollutant emitted during wildland fires that has the potential to pose significant health risks to individuals/communities who live and work in areas impacted by smoke events. Limiting exposure is the…
Year Published:
The growing scale of natural hazards highlights the need for models of governance capable of addressing risk across administrative boundaries. However, risk governance systems are often fragmented, decentralized, and sustained by informal linkages…

(1) Background: When a fire breaks out, combustibles are burned and toxic substances such as carbon monoxide (CO), polycyclic aromatic hydrocarbons (PAH), benzene, and hydrogen cyanide are produced. The purpose of this study is to evaluate the air…
Year Published:
Prescribed fire is a useful tool for building resilient landscapes in fire-prone areas across the globe. In the western U.S., prescribed fire is employed by federal, state, and Tribal land managers and planned during particular meteorological and…
Year Published:
During a wildland fire event, firefighters often receive significant exposure to smoke consisting of particulate matter (PM) and gaseous emissions. Major respiratory and cardiovascular health concerns are related to inhalation of smoke and…
Year Published:
Background: Due to anthropogenic climate change and historic fire suppression, wildfire frequency and severity are increasing across the western United States. Whereas the indirect effects of fire on wildlife via habitat change are well studied,…

As the 2023 fire season rages with unprecedented intensity in Canada, millions of people and countless animals across North America are exposed to wildfire smoke. Its harmful effects on human and animal health are only beginning to be explored in…
Year Published:
In recent years, the state of Colorado has experienced extreme wildfire events that have degraded forest and watershed health and devastated human communities. With expanding human development and a changing climate, wildfire activity is likely to…
Year Published:
As wildfire risks have elevated due to climate change, the health risks that toxicants from fire smoke pose to wildland firefighters have been exacerbated. Recently, the International Agency for Research on Cancer (IARC) has reclassified wildland…
Year Published:
Wildfires are increasing in frequency and intensity in part because of changing climate conditions and decades of fire suppression. Though fire is a natural ecological process in many forest ecosystems, extreme wildfires now pose a growing threat to…
Year Published:
The behaviour of wildland fires and the dispersion of smoke from those fires can be strongly influenced by atmospheric turbulent flow. The science to support that assertion has developed and evolved over the past 100+ years, with contributions from…
Year Published:
Wildfires are common occurrences worldwide that can destroy vast forest areas and kill numerous animals in a few hours. Climate change, rising global temperatures, precipitation, the introduction of exotic species of plants (e.g., eucalyptus),…
