Abstract Abstract-To facilitate natural regeneration of loblolly (Pinus taeda L.) and shortleaf pines (I? ecbinata Mill.) in an overstocked, uneven-aged pine stand in southeastern Arkansas, hardwoods were controlled by either basal injection of TordonQ 101 R. soil application of Velpat @ L, or rotary mowing followed by a broadcast spray of TordonB 101 applied over the hardwood stubble. After hardwood control, an improvement cut reduced merchantable pine basal area from 97 to 70 f? per acre, just before a better-than-average pine seed crop. Two subsequent improvement cuts in July 1987 and June 1991 left 55 and 48 ft2 per acre, respectively, in merchantable pine basal area. Twelve years after hardwood control, all plots had an adequate density of pine regeneration for uneven-aged stands, but dominant pine regeneration on treated plots averaged 16 ft taller and 2.2 in. larger in groundline diameter than the dominants on untreated plots.
