Appendix D. Ordination of medium-sized trees in subplots of the P plot.
Table D1. Basal area abundances of trees 10 < 50 cm stem diameter (m²/ha·10²) in two groups of subplots in P plot as detected by the partition of significant ordination axes. Values in bold font are ≥ 3-fold different. Species listed have weighted means ≥ 10 m²/ha·10².
