Fig. 2

Results from equivalence tests comparing NFI3 and NFI4 richness differences in: (a) woody species (WoodySp), (b) forest edge species (FoEdge), and (c) upper storey species (UpStorey). The horizontal lines are the confidence intervals (dot = mean). The caps mark the 90% CIs and the ends of the horizontal lines mark the limits of the 95% CIs. The dashed, vertical lines are the margins within which results were considered equivalent. Exact values of the means and 90% CIs are given to the right of the figure for NFI3 and NFI4
