"Relative change of several types of stem defects was studied over an 8-year period to determine the effects of crop-tree thinning on the development of tree quality. Special interest was given to changes in relative quality associated with defect indicators of crop trees compared to trees in unthinned plots. The relative quality classes of the crop trees went from "poor" to "medium" for red maple and "poor" to "good" for aspen. The oaks stayed in the poor classification and yellow-poplar remained unchanged in the medium classification. Results showed a decrease in the number of epicormic branches on the crop trees, and an increase in the size of live limbs.S3.

Low-quality hardwood stands present opportunity and challenge in the Interior Uplands. This guidebook discusses the primary causes of low-quality hardwood stands and offers management options for regenerating or improving these stands. Methods for evaluating stand and site potential are provided. A technique for comparing stands and prescribing treatment is also suggested.

S2After more than 20 years of USDA Forest Service research on the growth and yield of hardwoods in the Central States, we can now confidently make recommendations for the management and culture of upland hardwood stands that are predominantly oak. In this paper I will deal with the first 50 years of stand development under one logical thinning policy. S3.
