Cumulative variance (%) 66.35 28.79 4.66 0.21
  Loading coefficients Loading correlations
Variable PC1 PC2 PC1 PC2
LTSD 0.146 0.891 0.237 0.956
MR 0.583 − 0.283 0.949 − 0.304
H′ 0.582 − 0.209 0.948 − 0.225
TBD 0.548 0.287 0.893 0.307
  1. Loading coefficients of PC1 and PC2 are only represented since these components were the only significant components. Bold loading correlations indicate significant correlations
  2. PC1 principal component 1, PC2 principal component 2, LTSD large tree stem density, MR Margalef richness index, H′ Shannon-Weiner Diversity Index, TBD total biomass density
