Appendix G. Less abundant tree species in the 140-ha composite sample at Korup.

Table G1. The remaining 172 species (of the 245 in total) in rank descending order of basal area abundance (BA, m²·ha-1·100) for trees ≥10 cm stem diameter (< 5.0 m²·ha-1·100), together with their tree densities (number per 140 ha; exact counts for trees ≥ 50 cm diameter, scaled-up 10-fold for smaller trees) divided into three size classes. The abundances of the more abundant, first-73, species are given in Table 3 of the main text. Here also, at the end, are given the abundances of indeterminate taxa.
