Stem defects were studied over an 18-year period to determine the effect of thinning intensity on quality development of 80-year-old white oak trees. Seventy-nine white oak trees from a thinning study in Kentucky were analyzed from stereo photographs taken in 1960 and 1978. Stemrelated defects were measured on the butt &foot and second 8-foot sections of each tree. The number of defects per square foot of surface area increased significantly at the heaviest thinning level. The data suggest that
