Bill Gabbert at Wildfire Today recently posted a USFS video on the Caldor Fire. This scene from the video illustrates the fuels problem in the Sierras. Larry might tell us if this amount of fuel is as widespread as I think it is. In any case, the image shows so many piles that burning them might kill some of the green trees. If the fuels had been left in place, a prescribed fire might have killed even more trees, and a wildfire might kill all of them. The material could be removed mechanically, but at what cost? There’s no easy or cheap solution.
