Sažetak
The vascular flora of Bedekovčina has been investigated over the past few years. So far, 480 species have been determined, and sorted into 90 families. Within the data, the most well-represented plant families are: Poaceae (42 species), Asteraceae (39 species), Fabaceae (31 species). Geobotanical analysis of flora by means of floral elements, according to Horvatić et al. (1967), shows dominance by plants of the Euro-Asian floral element (33%), followed by widely spread plants (25%), plants of the European floral element (12%), the south-European floral element (9%), plants of circumholarctic distribution (8%), cultivated and adventive species (7%) as well as plants of other floral elements. The proportions of some floral elements indicate affiliation of the researched area to the Central European provinces within the Euro-Siberian-Northern-American region. Analysis of life forms according to Raunkiaer (1934) indicates predominance of hemicryptophytes (45%), followed by therophytes (25 %), geophytes (13%), phanerophytes (9 %), chamaephytes (5%) and hydrophytes (3%). The prevalence of hemicryptophytes is the after-effect of moderate continental climate influence, while the substantial content of therophytes can be explained by the presence of many ruderals. The flora of Bedekovčina comprises a relatively small number of threatened species listed in the Red Book of Vascular Flora of Croatia. Three vulnerable species have been determined, four nearly threatened and four data-deficient species. In the Bedekovčina area a large proportion of habitats are under heavy human influence, which results in the significant presence of neophytic species there. So far 33 neophytes have been noted, of which 29 are naturalized, and only four appear as casually escaped from culture. The composition and diversity of the flora in the area researched are consequences of a very diverse landscape consisting of ruderal habitats, cultivated land patches, woods, meadows and marshland vegetation.
