Fig. S1 Correlation among different biometric variables, and among these and leaf biomass (LW, also expressed as natural logaritnm, LnLW). Biometric variables are DBH (stem diameter at breast height), COD (stem diameter at collar), HTO (tree height), HTR (trunk height), HC (crown height), CA (crown area) and CD (crown diameter). Table S1 List of the different models with one or two biometric factors
