Pine growth was monitored for 10 yr after mechanically strip-thinning a dense, naturally regenerated, even-aged stand of 6-yr-old loblolly and shortleaf pines (Pinus taeda L. and P. echinata Mill.) in southern Arkansas. From age 12 to 16 yr, annual growth in height and dbh for 200 crop trees/ac was significantly better on precommercially thinned plots compared to unthinned plots. Commercial thinning was done during the 17th growing season, with volumes removed from unthinned plots averaging 8 cords/ac more than volumes removed from precommercially thinned plots. Pine volume production on precommercially thinned plots may have been reduced by crown scorch from two of three prescribed winter burns and by the disproportionate number of shortleaf pines on those plots as compared to unthinned plots.
