Abstract: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.

- The Journal of Forestry is the most widely circulated scholarly forestry journal in the world. In print since 1902, the Journal has received several national awards for excellence. The mission of the Journal of Forestry is to advance the profession of forestry by keeping forest management professionals informed about significant developments and ideas in the many facets of forestry: economics, education and communication, entomology and pathology, fire, forest ecology, geospatial technologies, history, international forestry, measurements, policy, recreation, silviculture, social sciences, soils and hydrology, urban and community forestry, utilization and engineering, and wildlife management. The Journal is published bimonthly: January, March, May, July, September, and November.
