Abstract
Loblolly pine (Pinus taeda L.) is commercially the most important timber species in southern Arkansas and the southern United States. Results of stand-level timber inventories have traditionally been reported in terms of volume, yet loblolly pine sawtimber is bought and sold based on biomass. A straight forward stand-level conversion from volume per hectare to biomass per hectare does not exist for Arkansas, thus complicating the valuation of standing loblolly pine sawtimber. Two equations were developed to predict stand-level, outside-bark, green biomass per unit area for loblolly pine stands in southern Arkansas. The merchantable sawlog equation presented herein explained approximately 95% of the variation present and had an average error of 4.2 percent when applied to validation data. The equation for total merchantable biomass explained about 99% of the variation and had an average error of 1.5 percent when applied to validation data. Use of these equations should simplify the valuation of standing timber in loblolly pine sawtimber stands in southern Arkansas.
