Wildfire exposure and fuel management on western US national forests.

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