We studied floristic, structural and ecological characteristics of the mixed beech-fir forests on the Kozara Mt. along with their syntaxonomy. Classification and ordination methods of were applied on 31 relevés sampled in the field. The classification has revealed three ecologically interpretable relevé groups: 1) mixed beech-fir forests with sessile oak (Festuco drymeiae-Abietetum Vukelić et Baričević 2007 quercetosum petraeae), 2) mixed beech-fir forests on acidic bedrock of Prepannonian area (Festuco drymeiae-Abietetum Vukelić et Baričević 2007 festucetosum drymejae), and 3) mixed beech-fir forests on limestone (Abieti-Fagetum dinaricum Tregubov 1957 = Omphalodo-Fagetum Marinček et al. 1993). The first one is the most xerophilous variant of these forests and has a transitional character between the pure sessile oak forests of Festuco drymejae-Quercetum petraeae (Janković et Mišić 1969) Janković 1968 and typical community of Festuco drymejae-Abietetum. It occurs on warmer aspects and has the largest share of Southeuropean floristic element among the studied communities. The second community is the most species poor and the most acidophilous type. Results suggest that it is syntaxonomicaly closest to the Centraleuropean types of mixed beech-fir forests, not having much in common with the forests of Illyrian Aremonio-Fagion alliance. The third one, albeit found on the Kozara Mt., floristically belongs to Illyrian mixed beech-fir forests which occur on Dinaric Mountains further to the south. This can probably be ascribed to the influence of the limestone bedrock.
