Description: Objectives of this study were to determine the effects of two levels of thinning on leaf biomass and acorn production of cherrybark oak (Quercus pagoda Raf.). To evaluate the effects of thinning 2 years after treatment, treatment plots were selected and blocked on the basis of initial stocking levels. Two levels of stocking and a control were established for each of five repetitions. Collection traps were randomly distributed on each plot to collect litter and acorns. The contents of the traps were collected weekly throughout the fall and winter of 2001. ANOVA was used to detect significant differences among thinning treatments regarding leaf biomass and acorn production. Two years after thinning, both leaf area and acorn production were affected by thinning level. Results, although preliminary, suggest enhanced leaf area and changes in acorn production. Level of thinning did have different effects over the short term.
