Abstract

A floristic study of Jarun Recreational and Sports Centre in Zagreb was conducted during the vegetation season of 2006 and partially in 2008. In total, 323 plant taxa from 70 families are presented in the list, out of which 156 are newly found, while the presence of 49 previously reported taxa was not confirmed. The most abundant family is Poaceae (11.76%), followed by Asteraceae (9.94%), Fabaceae (6.81%) and Lamiaceae (6.81%). The life form spectrum shows that hemicryptophytes are the most common life form (42.41%), followed by therophytes (24.77%). The phytogeographical spectrum shows the strong prevalence of Euro-Asiatic plants (44.10%), and a high number of adventive (9.94%) and Mediterranean plants (9.63%), while the Illyrian-Balkan chorotype is almost absent (0.31%). Only six taxa are found on the National Red List (Ophrys apifera, Alopecurus geniculatus, Carex panicea, Cyperus fuscus, Orchis militaris and Orchis tridentata), while 25 taxa are classified as invasive. Finally, we conclude that the flora of Jarun is greatly anthropogenically influenced, but still relatively rich.
