The proportion of explained variance (

*R*^{2}) of simple linear regression, intercept (*b*_{0}) and regression coefficient of DBH (*b*_{1}), and its standard errors (SE) were provided. The lower and upper boundary values of confidence intervals (CI_{LOW}, CI_{UP}) were computed for more conservative estimation. Significant values of*R*^{2}and*b*_{1}with*P*< 0.05 were italicised and underlined for easier comparison. Five species, namely*A. alexandrae, L. speciosa, M. × alba, P. serratifolia*, and*X. chrysanthus*, were excluded in (b) due to insufficient sample size.
