Abstract Substantial investments in fuel management activities on national forests in the western US are part of a
national strategy to reduce human and ecological losses from catastrophic wildfire and create fire
resilient landscapes. Prioritizing these investments within and among national forests remains a challenge,
partly because a comprehensive assessment that establishes the current wildfire risk and exposure
does not exist, making it difficult to identify national priorities and target specific areas for fuel management.
To gain a broader understanding of wildfire exposure in the national forest system, we
analyzed an array of simulated and empirical data on wildfire activity and fuel treatment investments on
the 82 western US national forests. We first summarized recent fire data to examine variation among the
Forests in ignition frequency and burned area in relation to investments in fuel reduction treatments. We
then used simulation modeling to analyze fine-scale spatial variation in burn probability and intensity.
We also estimated the probability of a mega-fire event on each of the Forests, and the transmission of
fires ignited on national forests to the surrounding urban interface. The analysis showed a good correspondence
between recent area burned and predictions from the simulation models. The modeling also
illustrated the magnitude of the variation in both burn probability and intensity among and within
Forests. Simulated burn probabilities in most instances were lower than historical, reflecting fire
exclusion on many national forests. Simulated wildfire transmission from national forests to the urban
interface was highly variable among the Forests. We discuss how the results of the study can be used to
prioritize investments in hazardous fuel reduction within a comprehensive multi-scale risk management
framework.
