After assessing the exposure to wildfire of communities across the Pacific Northwest Region, Oregon and Washington, the 50 most-threatened communities in each state were identified.
In the broadest sense, wildfire exposure encompasses the likelihood of wildfire burning a given location on the landscape, and the potential intensity of a wildfire if one were to occur. For this assessment the researchers focused only on wildfire likelihood because the effect of fire intensity on home loss rate is not well studied, and because the inclusion of intensity for this and similar assessments did not influence the conclusions. Wildfire likelihood is measured by annual burn probability, a measure generated by comprehensive simulation of wildfire occurrence and spread (see section below on Wildfire hazard simulations).
The research was commissioned by the U.S. Forest Service’s Northwest Region.
