Exactly how are you going to clear millions of acres of brush and sage ? And brush doesn’t generally grow under old growth pines etc… not enough light through the canopy . Also the bark on old Ponderosas is so thick it’s damn near fireproof .
Most overly brushy areas in a forest occur in logged areas .
But I don’t think these fires are in forested areas… most likey foothills with sagebrush and such .
I spend a lot of time wandering through the mountains.
