Technical Bulletin No. 0801: Economic Comparisons Between Even-aged and Uneven-aged Loblolly Pine Silvicultural Systems

This study compares financially optimal uneven-aged and even-aged silvicultural regimes of loblolly pine (Pinus Taeda). Uneven-aged regimes that maximize net present value (NPV) are found by quantifying the effects of diameter distribution (Q-factor), maximum diameter, cutting cycle, and residual basal area on NPV. For the benchmark inputs, the regime yielding the highest NPV had a maximum diameter of 12 in.
