Historical and functional aspects of plant biodiversity - an example on the flora of the Vukova Gorica region (Central Croatia)

Vukova Gorica region, located in Western part of Central Croatia and displaying an area of 3.2 km2, has a vascular flora of 531 taxa from 96 families. Seven main habitat types were recognised. For each type of habitat, biological and chorological spectra have been calculated, as well, as a cross spectrum representing the relationship between the chorological types and the life forms. The spectra were analysed using correspondence analysis (CA). The present state of diversity can be considered as the result of the natural and historical circumstances and the exstensive anthropogenic impact. It is concluded that the human impact was essential for the richness of the flora and its chorological structure. The high alpha-diversity index recorded on the studied area shows that Vukova Gorica region is one of the floristically richest region in Croatia.
