Abstract:

Compatible equations for predicting cubic volume and basal area growth were developed by simultaneously estimating the coefficients in both models. The simultaneous estimation procedure gave stable estimates for the basal area projection equation regardless of the merchantability definitions imposed in the volume projection equation. Prediction equations were fitted using the simultaneous estimation procedure with growth data from thinned loblolly pine plantations established on old-field sites in the Piedmont and Coastal Plain of Virginia. Forest Sci. 30:86-93.
