Study finds prescribed burns reduce wildfire severity and improve long-term air quality in California

Summary

This article examines research by Higuera-Mendieta et al. on the air quality impacts of prescribed burns (low-severity fires) in California. Using 20 years of satellite data, the study found that prescribed burns immediately reduce the probability of very-high-severity wildfires in the same location, provide long-term protection lasting up to a decade, and significantly decrease overall air pollution compared to uncontrolled wildfires. The research addresses the trade-off between the initial smoke from prescribed burns versus the much larger air quality impacts of severe wildfires, supporting the expanded use of controlled burns as a net positive for air quality.
