Sažetak

The process of urbanization is one of the most extreme forms of anthropogenic habitat modification. Negative trends and their effects on the one hand, and concern for the preservation of biodiversity and quality of city life on the other, are the initiators of urban flora research. The flora of urban areas in Croatia has not been the subject of sustained research and therefore floristic records for most of the larger cities are unknown. The research area is located in northwest Croatia in the city of Zagreb, on the right bank of the Sava River. In the area of Konopljenka and Piškorovo a total of 351 taxa of vascular plants belonging to 81 families were recorded. Seven of them (2%) were pteridophytes (Equisetidae), two of them (0.6%) gymnosperms (Pinidae), and others were angiosperms (Magnoliidae). Among angiosperms, 71 taxa (20.2%) belong to monocotyledons (superorder Lilianae) and the other 271 taxa (77.2%) from 65 families belong to other superorders of angiosperms. Families with the highest number of taxa are Poaceae (11.4%), Asteraceae (9.1%), Fabaceae (7.4%), Lamiaceae (5.7%) and Rosaceae (5.4%). Phytogeographical analysis showed that the Eurasian geoelement predominated (30.1%), followed by cosmopolites (27%). The most common life forms are hemicryptophytes (48.1%), therophytes (22.2%) and phanerophytes (11.4%). Among recorded taxa 22 are invasive alien species (6.3%), two taxa (0.57%) are threatened and 64 taxa (18.2%) are under legal protection. If we compare the number of species per unit area and proportion of protected and threatened species with the results of similar floristic researches in central and north Croatia we can conclude that it is a relatively rich floristic area.
