Tri-plot of redundancy analyses (RDA) showing existing relationships between soil properties, sites, treatments and understory plant communities. Panel a represents taxonomic groups and plots that are grouped by treatments based on soil properties contributing significantly to the model. Panel b represents the ordination of plots that are grouped by sites based on soil properties contributing significantly to the model. Sample treatments are indicated by symbols (CON: control; SIN: single-tree selection cut; GRP: group-selection cut; GRPS: group-selection cut with scarification), explanatory variables by arrows. Percentage variance explained along each axis corresponds to R2
