Bark beetle infestations on tree level in spruce primeval natural forest in the ‘Pol'ana nad Detvou’ natural reserve in Central Slovakia were classified into communities of Hylurgops palliatus/H. glabratus, Dryocoetes hectogaphus, Ips typographus, Xylechinus pilosus, Polygraphus polygraphus and Xyloterus lineatum/Ips typographus. Effects of host and site factors in separating the bark beetle communities were quantitatively evaluated. Cluster and discriminant analyses were used. The relative influence of each factor for community separation varied among communities. The most important factors were the state of the material, canopy closure and the stage of the primeval natural forest. Dimension, stage of decay, elevation, exposure, soil acidity, potential forest vegetation type and the year of succession had statistically significant effects.
