NFI indicators (mean ± standard error) across the five regions: indicator of plant presence and of plant high cover in all forests, %A_{PC > 0, CC ≤ 100} and %A_{PC > 50, CC ≤ 100} (a and c), and indicator of plant presence and of plant high cover in open-canopy forests, %A_{PC > 0, CC < 50} and %A_{PC > 50, CC < 50} (b and d), for (a and b) plant groups and (c and d) plant species, respectively. In each graph, species and groups are ranked by decreasing order of (a and c) %A_{PC > 0, CC ≤ 100} values or (b and d) %A_{PC > 0, CC < 50} values. Please note that the scale of the y-axis changes between the plots
