Buzzh-
I wasn't saying that sterilization is either common ( I do however think that 5% is a bit on the light side on the districts I was on) nor is somehting that lasts forever. Point is, it does happen but indeed, as you stated, depends on the factors mentioned (soil type, depth, parent materials, litter depth, duff depth, aspect, fire intensity, duration, etc.)
I also heartily agree that most wildfires should be (again depending upon the variables previously mentioned) allowed to burn in many areas. However, I don't think that "soil sterilization" really has ever been a key factor into departmental or agency decison regarding supression (I belive you called it a reason to promote an agenda) any where I have worked, maybe its different in your region?
My whole point gets back to the individual stand/prescription writing perspective- I would rarely call for fire as a vegatative management tool on marginal soils on our district...more so due to erodibility factors than sterilization problems. Fact of the matter is that most of these units themselves (I am speaking of) were marginal in productivity at best and shouldn't have been harvested in the first place!
Granted, doghair lodgepole is a lot more prevalent but try a nice thick patch of knobcone pine if you want to see some extreme heat!Let me tell you, if there is any forest type that burns hotter and more intensely than a nice thick lodgepole forest...I havent found it.
