Preferred NLC-F and NLC-O of native plant species, which are classified into threatened and not threatened species.

a , Two-dimensional plot indicating the preferred NLC-F and NLC-O of each species. Each dot indicates one species. Red dots indicate threatened species and blue dots indicate not threatened species. b , Number of dots within each subgroup along the x axis (0%, 0–25%, 25–50%, 50–75%, 75–100% and 100%). c , Number of dots within each subgroup along the y axis (0%, 0–25%, 25–50%, 50–75%, 75–100% and 100%).
