Every dollar spent on forest fuel treatments saves $3.75 in wildfire damages, study finds

Phys · · 529 words · By UC Davis

A study led by UC Davis researchers analyzed nearly 300 wildfires in the western United States to evaluate the economic impact of forest fuel treatments. The findings suggest that investments in thinning and prescribed burns reduce wildfire spread, severity, and associated economic damages, including health impacts and structure loss.
