A Framework for Stand Structure Projection of Uneven-Aged Loblolly-Shortleaf Pine Stands
Abstract:A growth and yield model for uneven-aged loblolly-shortleaf pine (Pinus taeda L.-Pinus echinata Mill.) was developed. Stand-level equations for merchantable basal area, sawtimber basal area, quadratic mean diameter, and maximum tree diameter were derived first. Parameters for the doubly truncated Weibull distribution were obtained by the "parameter recovery" technique by using estimates of maximum diameter, quadratic mean diameter, and the sawtimber-merchantable basal area ratio. Compatibility for basal area estimates is thus maintained between the stand-level estimates and those produced from the Weibull distribution. Because inventory data were used to develop the model, potential users should be cautious in applying the model on an operational basis. For. Sci. 34(2):321-332.
