The Probable Mechanism of the Protective Action of Resin in Fire Wounds on Red Pine
Fire wounds are generally considered common courts of entrance for wood destroying fungi. Undoubtedly in many tree species such wounds are commonly invaded by wood destroyers, but in Minnesota a large majority of mature trees of red pine (Pinus resinosa) are entirely free of decay behind fire wounds, even when such wounds include one-fourth the circumference of the tree and have been present for over half a century. The large amount of resin in the wounds acts as a water-proofing layer, and thus prevents the entrance of wood-destroying fungi.
