Relationships between gap fraction (log-scale) and predictors used in the final model. (a) Soil cation concentration (SCC). (b) Non-forest distance (km) (log-scale). (c) Floodplains cover fraction. (d) Mean monthly water deficit (mm)—Mean_def. Red triangles on panel (d) represent samples with floodplains cover fraction ≥ 0.5. The dashed line represents a linear model.
