Abstract:
Volume growth was modeled for even-aged Emory oak stands. Data were collected from 84 temporary plots located in the proximity of the Huachuca Mountains of southeastern Arizona. At each plot, trees were measured for current volume using non-destructive sampling techniques. Variable-density yield tables for Emory oak were developed from sample data collected on temporary plots. Yield tables are a system of equations used to estimate current yield and predict future yield. A system of equations consisting of two components was developed in this study. The first component predicts yield, the second predicts future yield by estimating changes in density. Basal area is the density measure used. By using basal area, current yield is obtained by determining present stand conditions. Future yield is estimated by adjusting basal area for future stand conditions. Estimated changes in basal area are placed back into the yield equation and solved, providing an estimate of future yield. Therefore, yield and future yield of Emory oak can be estimated by using basal area as the density variable. The variable-density equations are used to estimate the volume of unthinned or thinned stands of Emory oak.
