Figure 3: The significant drivers of native species richness at the small (1 x 1 m) and large (3 x 3 m) grain, and the difference in native species richness (Native Δ9-1) between large and small grain. a . Elevation, b . Northness, c . Slope d . Distance to nearest drainage line. e . Topographical wetness index (TWI), and f . Presence/absence ofAzorella selago (the boxplots show the median and minimum/maximum values, different letters above plots indicate significant differences in mean values between presence and absence of A. selago at p ≤ 0.05). The graphs show the effect of predictors on the response variable after the effect of all the other predictor variables had been considered. Model parameters are shown in Table 1a, b.
