I realizing burning is the best way to restart the regrowth process, but considering how difficult it would be to get all the equipment in to make firebreaks and how steep the terrain is, I'm seriously considering aerially spraying some of my timbered areas to knock them back.
When you describe your place it sounds like you're describing mine. I asked my forester about doing a burn and he said absolutely not, terrible idea. No way to control it because of the steep terrain and unpredictable wind shifts.
