DescriptionThe effects of diameter-limit cutting on the future species composition and development of 60-80 year-old upland oak stands were studied in southern Ohio. Four treatments, 11-inch diameter-limit cut, 14-inch diameter-limit cut with selective thinning, 14-inch diameter-limit cut with low thinning, and uncut control were evaluated on medium oak sites (black oak site index 60-75 ft) and good oak sites (black oak site index > 75 ft). Twenty 1.8 acre treatment areas were established, 2 complete replications of the 8 treatment combinations and one partial replication. One year after cutting, understory species counts were made for all trees ≤ 3.5 inches dbh on 20 milacre plots within each treatment area. Twenty years after cutting, regeneration ≥ 3.5 inches dbh was tallied on 150x150 foot plots centered in each of the treatment areas. Regeneration 0.6-3.5 inches dbh was inventoried using nine 0.01 acre subplots systematically located within each 150x150 foot plot.
