Abstrakt: Mount Medvednica (northwestern Croatia), mostly consisting of slates and marls, rises to the north, above the Croatian capital of Zagreb, from 300 to 1,035 m a.s.l. A floristic research was carried out in the area of Medvednica Nature Park, which consists mainly of the western part of the mountain. On the whole, 1,352 taxa of vascular plants were recorded from all sources (field observations, literature and herbaria). Out of these, 48 taxa are strictly protected, 228 are protected, 67 taxa are considered threatened according to the IUCN categories, and 9 taxa are endemic for the Croatian flora. The life-form analysis of the investigated flora shows the predominance of hemicryptophytes, followed by therophytes and geophytes, while the chorological analysis has evidenced the prevalence of Euro-Asiatic, South European and cosmopolite geographical groups. The biological/chorological cross-spectrum was laid out by considering the percent of every life-form for each geographical element. In order to evaluate the floristic richness of the studied area, the α-index was calculated and then compared with the α-indices of similar regions in Croatia and several European countries. A floristic diversity map of Medvednica Nature Park is presented here for the first time. [ABSTRACT FROM AUTHOR]
