A comparison of loblolly pine growth and yield on pure pine and mixed pine-hardwood sites

Abstract

The case histories of four loblolly pine (Pinus taeda L.) sites were examined to determine if differences in growth and yield could be associated with stand type. The stand types were pure loblolly pine and mixed loblolly pine-hardwood. All sites were located on silt loam soils and mechanical site preparation was carried out on all sites before regeneratton. The pure lobloliy pine sites had greater rates of individual tree growth and yielded more inside-bark volume per acre than pine trees on the mixed loblolly pine-hardwood site. Pure lobiolly ptne yielded approximateiy 830 to 1,520 ft³/ac 9 years after site preparation. In contrast loblolly pine trees on the mixed pine-hardwood site yielded only 152 ft³/ac after 9 years.
