Abstract:Losses traceable to 10-year-old wounds on yellow birch and sugar maple were low, only 3.1 and 0.2 percent of potential log value and 0.7 and 0.5 percent of potential lumber value, respectively. Stem wounds were far more serious than root wounds, resulting in all of the loss in log value for both species, all the loss in lumber value for sugar maple, and 91 percent of the loss in lumber value for yellow birch. Predicting high-risk trees by wound characteristics is possible, and if these trees are harvested within 10 years after wounding, losses should be minimal. With reasonable care in using equipment and loads as large as the rubber-tired tractors with integral arches skidding tree lengths, losses can be held within these low limits without serious effect on silvicultural considerations.

- 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.
