OK, This is one of my favorite myths to debunk.

Standing dead trees don't burn....

On June 18, 2002, the Hayman fire front roared into the tussock-moth-killed stands on the east and north sides of Thunder Butte, and just died. Once there was no canopy to carry the flames, the fire dropped down into the ground clutter and duff and just smoldered about. In areas on either side of the insect-killed area, the fire kept on going, destroying several thousand acres of forest and several houses in the Trout Creek Estates and the Horse Creek areas. If the fire hadn't dropped from the canopy in this area, the houses along West Creek would have been toast also.
If the trees still have their needles, watch out, but the trees in this photo would need a blow torch and some gasoline to get them going again.
Granted, I'm a fish squeezer, not a forester, but the foresters I've talked to about this are pretty sure these high-severity burn areas are not likely see another major wildfire in the next 60-100 years.
Google "Beschta Report" for more info on burn area restoration and the effects of salvage logging on long-term recovery.
