Figure 6

The graph exemplifies the experimental design showing one out of five blocks. Each block includes one rodent exclusion plot (indicated by a bold solid line) and rodent control plot (indicated by a bold dashed line) plot. Within each plot, one gastropod exclusion subplot (indicated by a solid line) and gastropod control subplot (indicated by a dashed line) were established. Within each subplot, sub-subplots (depicted with smaller squares) were established that were either subjected to disturbance (shaded squares) or were left undisturbed (open squares). These sub-subplots were furthermore randomly assigned to receive no seeds (C), a seed mixture of 20 exotic species (E) or 20 native species (N).
