Our assessment of plant taxa prefer- ences reveals that Greece is in fact a country of cultural landscapes. Most common are the plants of rural and disturbed habitats (18.1%), followed by grassland and low-shrub species, with 17.7% representing sub-Mediterra- nean/temperate pastures and meadows at low to mountain altitudes and 15.4% representing Mediterranean meadows rich in annual species and phrygana (Figure 4). 350 350 300 300 250 250 200 200 150 150 100 100 50 50 0 0 IoI IoI NPi NPi SPi SPi Pe Pe StE StE EC EC NC NC NE NE NAe NAe WAe WAe Kik Kik KK KK EAe EAe Plants occurring in forests and scrubs account for only 13.7% of the Greek flora, although (a) they are very diverse and widespread in Greece; (b) al- most all tree and shrub species found in Greece are included in this habitat category.
