Heating of Tree Trunks in Surface Fires
Abstract:Near the ground line, external heating of pole-size longleaf pines was essentially identical in headfires and backfires that consumed 8 tons of pine litter per acre; above 1 foot, temperatures were much higher in headfires than in backfires. At all levels the leeward side of trees was heated more intensely than the windward side. Maximum and average temperatures usually were lower in bark fissures than on bark plates. Lethal cambium temperatures were recorded in some trees but not in others. Cambium injury occurred in streaks and spots and covered appreciable areas only on the leeward side of some trees burned in headfires.
