Sažetak
This research comprises seven localities of the beech-fir virgin forests at elevations ranging from 840 m (Čorkova uvala) to 1380 m (Nadžak bilo). Of the 21 surveyed plots (approx. 500m2) in optimal stage of development, 75% are situated on slopes exceeding 15 degrees, while northern and eastern aspect prevails. The average annual precipitation is 2200 mm, and the average annual temperature is 6°C, with range between -6°C and 21°C. The chorological spectrum analyses has shown that most represented plants belongs to Euro-Asian, European and South-European floristic elements, while the least represented were those belonging to Mediterranean, East-European and South-European elements, as well as adventive and cultivated plant species. With respect to life forms, hemicryptophyta and geophyta prevails, while the terophyta and chamaephyta are least frequent life forms. The average number of recorded plant species per plot is 31, with values ranging from 17 to 46. The average value of the Shannon-Wiener Diversity Index is 3.09, and of the Evennes Index 0.91. Based on the floral composition, the analysed stands belongs to four Omphalodo-Fagetum [Tregubov 1957] Marinček et al. 1992 subassociations: homogynetosum sylvestris ; galietosum odorati ; aceretosum pseudoplatani and seslerietosum autumnalis. Future research should be extended to encompass initial and decomposition stage of virgin forests as well.
