The real answer is not to reduce or eliminate forest fires,
but to reduce their impact and to prevent catastrophic stand
replacement fires. The key to that is to maintain fuel
loads at manageable levels through:
1. Proper stocking control - Carry tree density levels at no
more than about 40-50% of "full" stocking (measured from either
"normal" Stand Density Index or "Maximum" Basal Area) through
relatively frequent light entries.
2. Prevent the creation of "fuel ladders" by pruning, and
other actions that break the chain of continuous fuel from
near ground level to the top of the stand.
3. Control fine fuels through judicious use of grazing.
4. Harvest most dead and dying trees frequently. (But be sure
to leave some for wildlife eg. cavity nesters)
5. Allow "naturally" occuring fires that are burning during
"safe" conditions, ie. during periods of high moisture and low
winds to consume excess fuel. Ecologically most forests
evolved under some sort of fire regime and are adapted to fire.
