| Popis | Man-made habitats are considered to be the important hotspots for species naturalization. Due to high propagule pressure caused by human activities they serve as a source of introduction of alien plant species. We used the database of cultivated ornamental trees and shrubs for Brno, Czech Republic, to determine the significance of introduction pressure as a factor in woody plant naturalization. From all cultivated woody taxa, 15 % was recognized as spontaneously growing in the urban area and there was a significant relationship between the frequency of cultivated species and their ability to spontaneously occur in urban area. The highest potential to spread from cultivations have temperate Europe native species, followed by neophytes originated from America or Central and Eastern Asia, respectively. |
