Association Abieti-Fagetum "pannonicum" Rauš 1969 has an invalid name and still undefined position in geobotanical and phytosociological sense. In 2000 and 2001, within the Abieti-Fagetum ass. on central part of Medvednica mountain, the flora and different habitat factors of 12 plots (50 x 50 m) were investigated. On the whole, 119 taxa of vascular plants were recorded (one subendemic and three vulnerable). In spite of being considered a differential species for Dinaric fir-beech forests, the species Sorbus aucuparia L. was recorded with a high percent of share. The life form analysis confirmed that Medvednica’ s flora belongs to the moderate continental climate. The influence of habitat factors on floristic variability of the plots was estimated by Canonical Correspondence Analysis. The changes in altitude, pH and inclination have the strongest influence on the changes of floristic structure.
