The first bar plot shows the percentage of total cover for each taxonomic family in the MARA database. Families contributing less than 4% cover are grouped under ‘Others’ (68 families) (A). The pie chart illustrates the percentage of total cover for each life form according to the Raunkiær classification in the MARA database (P = Phanerophyte, NP = Nanophanerophytes, Ch = Chamaephyte, H = Hemicryptophyte, G = Geophyte, T = Therophyte) (B). The latter bar plot shows the cover percentage of alien plant taxa (APT) for each taxonomic family in the MARA database. Families contributing less than 4% of cover are grouped under ‘Others’ (9 families) (C). The pie chart illustrates the percentage cover of alien plant taxa (APT) for each life form according to the Raunkiær classification in the MARA database (P = Phanerophyte, H = Hemicryptophyte, T = Therophyte) (D).
