Crooked or leaning trees are particularly susceptible to damage because the flames are more likely to be directly below the stem, thereby increasing the amount of heat received at the bark's surface. Higher fire intensity and severity increase mortality and serious injury. These sprouts may be more vigorous and less susceptible to rot or other damage. Sprouting ability typically decreases with increasing d.b.h. Birds and mammals may transport seeds from adjacent unburned areas, and seedling establishment may occur.
Prescribed fire can be an important tool for regenerating oak stands.
