a-c, Percentage distribution of threatened and not threatened species along preferred NLC (a), NLC-F (b) and NLC-O (c). d-f, Percentage distribution of common and rare species along preferred NLC (d), NLC-F (e) and NLC-O (f). h-i, Percentage distribution of native and exotic species along preferred NLC (g), NLC-F (h) and NLC-O (i). ‘+’ indicates values that are above expectation according to our Contingency Analysis (see supplementary analysis for detailed results).
