Fig. 6

Distribution of forested area by post-fire crown index (Crown PFI), calculated from crown outcomes for trees > 12.4 cm (> 5 in) diameter for the six 2020 megafires in Oregon and southwest Washington for area represented by Forest Inventory and Analysis (FIA) conditions for which (a) wind speed did not exceed 2.25 m/s (5 mph) when fire arrived and (b) wind speed was at least 2.25 m/s. The bars labeled salvage represent the forest area that experienced post-fire salvage, such that Crown PFI is indeterminate. Forest area and FIA condition count for each wind speed class and Crown PFI are posted at the top of these charts
