| Description | Flora of large cities is very rich in species. During our research in 32 central and western European cities in four climatically defined zones, we aimed at the floristic inventories of seven largely man-made habitats, such as historical squares, main boulevards, recently disturbed ruderal places, abandoned places with perennial vegetation, city parks, residential areas with blocks of flats and residential area with family houses. Based on the data collected, we tried to identify factors responsible for the high species richness and taxonomic composition of city floras. Our results show that the pool of alien species is quite similar in all cities studied and that introductions of alien species reduce the differences between floras of particular cities. Consequently, the differences are mainly due to remaining patches of natural and semi-natural habitats, which harbour indigenous species. |
