In this 1-hour webinar hosted by the Northwest Fire Science Consortium, findings will be presented from a recently completed study, funded by the Joint Fire Science Program, on landscape fuel treatment effectiveness within recent large wildfire events in north-central Washington State. First, an overview will be provided of climate change and wildfires and the imperative for broad-scale adaptive management to increase landscape and community resilience to future wildfires. Next, findings will be reported on the effects of prior fuel reduction treatments, biophysical environment, and weather on fire severity. The study also evaluated fireline effectiveness and how past fuel treatments assisted in safe and effective response.
