Twosome needs to put the fires out and start to thin the forests.
Periodic fires do not get hot enough to kill the trees but if you wait ten years for lightning to do the job then the underbrush and dead wood is so dense that the flames are super hot and the trees are all burned up. Early settlers in the 16oos and explorers before that remarked on the New England forests being so clear that "you could march an army through the forest."
