Smoke

If they could figure out how to get rid of the undergrowth or if they are clear cutting.....take the under growth with it and re-plant. Selective cutting is expensive, but probably not as expensive as a huge fire. It the 'kindling' that get it started and guessing but....20% of the continued fuel source? Do they integrate a large gap in the trees during a re-plant so the fire has a tougher time to 'jump' to the next batch? I wonder what kind of consequences cloud seeding would have over the long term.
Good points & questions.
