Abstract

Changes in limb-;elated stem defect were studied from 1977 to 1982 on 595 mixed-oak trees fbllowing a schedule of thinnings dating back to 1962. All of the thinnings were controlled by stocking goals rather than predetermined time intervals. Results show that heavy and moderate thinnings, as opposed to light thinnings,lhad an adverse effect on the number and size of live and dead limbs. The light thinnings resulted in fewer live and dead limb defects per square foot ofisurface area but much slower diameter growth.
