Excerpt from Proceedings of the Eighth Southern Conference on Forest Tree Improvement: June 16-17, 1965, Savannah, Georgia The current low utilization of hardwood logs is primarily due to the small size of existing trees. Small trees can produce only a small amount of the best grades of lumber and veneer. Even under intensive silviculture a preponderance of low-grade material must be expected from small trees. Timber size is important because larger trees are cheaper to harvest, transport, and process, and tend to have higher product value than small trees. Even though many small hardwood logs are being used, larger timber is essential to maintain the competitive position of most forest industries. At present only about 11 percent of the total volume of eastern hardwoods is in trees 19 inches and larger (u.s. Forest Service 1965) One way to increase utilization is to wait for our trees to grow larger. But, this may not occur soon enough to meet our needs. Currently recommended cultural treatments applied to natural stands can increase growth and utilization in a reasonable time (roach But we also need more intensive cultural and genetic techniques that greatly increase the utilization of the most valuable hardwood species in the shortest possible time.
