Hidden risk pushes 459 Northwest communities higher on wildfire danger scale

Phys · · 802 words · By Steve Lundeberg

Researchers from Oregon State University and The Nature Conservancy have developed a new wildfire risk assessment tool that incorporates social vulnerability alongside environmental hazards. The study found that 459 communities in the Pacific Northwest face higher risks than previously estimated, suggesting a need for more equitable distribution of mitigation resources.
