Wildland fire smoke risks are not uniformly distributed across people and places, and the most vulnerable communities are often disproportionately impacted.

In recent decades, there has been a significant increase in annual area burned in California's Sierra Nevada mountains. This rise in fire activity has prompted the need to understand how historical forest management practices affect fuel composition and emissions.

Understanding of the vulnerability of populations exposed to wildfires is limited. We used an index from the U.S. Centers for Disease Control and Prevention to assess the social vulnerability of populations exposed to wildfire from 2000–2021 in California, Oregon, and Washington, which accounted for 90% of exposures in the western United States.

Dominant causal explanations of the wildfire threat in California include anthropogenic climate change, fire suppression, industrial logging, and the expansion of residential settlements, which are all products of settler colonial property regimes and structures of resource extraction.

Wildfires are increasing in frequency, raising concerns that smoke can permeate indoor environments and expose people to chemical air contaminants. To study smoke transformations in indoor environments and evaluate mitigation strategies, we added smoke to a test house.

Background Wildfires often have long-lasting costs that are difficult to document and are rarely captured in full. Aims We provide an example for measuring the full costs of a single wildfire over time, using a case study from the 2010 Schultz Fire near Flagstaff, Arizona, to enhance our understanding of the long-term costs of uncharacteristic wildfire. Methods We conducted a partial remeasureme

Background Plant flammability is an important factor in fire behaviour and post-fire ecological responses.

Background. Social science that seeks to advance wildfire adaptation in the southwestern US states of Arizona and New Mexico remains underdeveloped in comparison with other regions in the USA. Aim.

Wildfire science, policy, and practice lack systematic means for “tailoring” fire adaptation practices to socially diverse human populations and in ways that aggregate existing lessons.

Escalating wildfire activity in the western United States has accelerated adverse societal impacts. Observed increases in wildfire severity and impacts to communities have diverse anthropogenic causes—including the legacy of fire suppression policies, increased development in high-risk zones, and aridification by a warming climate.
