I just backpacked through major burn zones from 2003 and 2020, and that is exactly how it worked. Mt Washington was burned to the ground in 2003 (B and B Complex fires), every single tree was burned down, even the big ones. The current new growth is about 5-10ft. In between Bend and Crescent there is a strip of forest that is completely orange because of the drought: top to bottom, every tree; it looks painted. The burn from last year near Lake Detroit has regions where no tree survived due to drought + fire. I recommend you backpack/drive/hike parts of Central Oregon to see the damage, and impending risk, for yourself.
