The boxplots show the taxa richness across the two plot types (roadside and inland plots) and elevation ranges (below 1200 m and above 1200 m a.s.l.) Significant differences between box-plots are highlighted using statistical significance markers (*) according to the Student’s t-test (* p < 0.05, ** p < 0.01).
