Any tips for protecting trees from fire damage?
At our building site, we've bulldozed about 5 acres of almost mature forest into 2 very large, nicely packed slash/burn piles. The small one (about 100ft x 50ft) has a couple of real nice dogwoods and small (3" dia) beech trees around the pile that I'd like to try to save when we do the burns. The keepers at the closest points are about 20 ft from the piles. I HOPE to try to burn the piles "surgically", keeping the major heat just in the center, and push the ends into the center as it burns. This may not go quite like I'm hoping! The piles have now been drying for about 8 weeks, and I figure I need to wait until after the first good freeze so the keepers will be dormant, so probably another 6-8 weeks until burn time. I have good water supply, so I can saturate the roots good before and during the burn. Anything else I can do?
