Table S: Utilisation and land cover variables used to determine the level of utilisation of each site. The average value of each variable for each level was calculated (Sites: High n=2; Medium n=4; Low n=3). One way ANOVA results (df = 2 for all variables) are given to demonstrate differences between each level. Where a significant difference was demonstrated between the levels the post-hoc test Tukey HSD was performed to ascertain which levels differed. P< 0.05 indicates a significant difference.

Table S2: Differences between tree species abundance, richness and diversity at different utilisation levels, using one-way ANOVA (df =2 for all variables). The post-hoc test Tukey HSD was performed on significant ANOVA results to determine how the levels differed. Two sites from each utilisation level were used to ensure even sampling. P< 0.05 indicates a significant difference.
