DescriptionYield and stand structure predictions from an unthinned loblolly pine plantation yield prediction system (USLYCOWG computer program) were compared with observations from 80 unthinned loblolly pine plots. Overall, the predicted estimates were reasonable when compared to observed values, but predictions based on input data at or near the system's limits may be in error by as much as 14 percent. Correlations between observed and predicted values for the variables selected ranged from 0.72 to 0.96.
