What is it about?
Wildfires increasingly threaten communities near natural vegetation. Using a validated wildfire model, we show that combining vegetation management with home ignition zone mitigation reduces wildfire damage more than either strategy alone. Targeting the most influential locations provides the greatest community-wide protection.

Why is it important?
We quantify how the spatial placement of wildfire mitigation influences community-wide outcomes. By integrating vegetation management and home ignition zone mitigation within a validated network-based wildfire model, we show that targeted interventions substantially outperform randomly distributed mitigation in reducing building vulnerability. The results provide a quantitative basis for prioritizing mitigation investments and support more effective wildfire risk reduction strategies in the wildland–urban interface.
Perspectives
This work was motivated by the need to understand how vegetation management and home hardening interact across an entire community rather than as independent actions. I hope these findings contribute to more evidence-based wildfire mitigation policies and encourage planners and decision-makers to prioritize interventions that maximize community resilience while making the most efficient use of available resources.
