Relative basal area for each tree species recorded in every sites

This table contains the relative basal area for each tree species sampled at each site. In each of the 192 sites, the diameter at breast height (dbh) and species of the 25 trees closest to the centre of the plot and over 5 cm bdh were recorded. Total basal area was calculated for each species in each site and divided by the total basal area of all species in each site to produce the relative basal area. Refer to the associated publication (Blanchet et al. Consensus RDA across dissimilarity coefficients for canonical ordination of community composition data, Ecological Monograph) for more details on sampling protocol and table E2 of this same publication for the abbreviation of the tree species.
