Allometric equations of sapwood basal area (SBA, cm2) against stem diameter at breast height (DBH, cm) for the seven tree species. The equations are of the form log10SBA = a(log10DBH) + b. The sample size (N), coefficients (a and b), determination coefficient (R2), standard error of the regression (SEE), P values, and the logarithmic correction factor (CF) are given.
