  1. Mean relative occurrence values (%) are presented and two-way permutation ANOVA P-values. Significant treatment effects are represented by a P-value in bold (P < 0.05). Within rows, means followed by the same letter do not differ significantly from one another at α = 0.05 according to pairwise Tukey’s tests
  2. CON controls, SIN single-tree selection cut, GRP group-selection cut, GRPS group-selection cut with scarification
