Western Wildfire Resilience Index (WRI)

The Western Wildfire Resilience Index (WRI) is the first open-access, holistic index to quantify wildfire resilience across the North American West at fine spatial resolution. It integrates eight socio-ecological domains (Infrastructure, Communities, Livelihoods, Sense of Place, Species, Natural Habitats, Water, and Air Quality) into a single composite score ranging from 0 (low resilience) to 100 (high resilience). The Index is designed to inform wildfire preparedness, response, and recovery policy across communities and landscapes.
