Communities of epigeic beetles were studied on two localities: Třebovice in the military area Boletice and Vadkov in the foodhill of Blanský les Landscape Protected Area in South Bohemia. The distance between localities is 7,25 km. Six biotopes were studied in both localities: grasslands, wetlands, fields, coniferous forest habitat, habitat mixed forest and deciduous forest habitat. Pitfall traps were used for collecting of material in period May - November 2012. Together 5 families (Carabidae, Elateridae, Silphidae, Curculionidae, Geotrupidae), 18 species and 1426 specimen of epigeic beetles were collected. Species were divided according to their ecological requirements of anthropogenic tolerancy into three groups (I and II relics and eurytopic species) (Boháč, 1999). In the monitored area Trebovice I found a total of 5 families with 16 species, compared to 3 for the families of the 11 species in Vadkov. The activity of beetles was very similar in both localities (Trebovice - 726 specimen, Vadkov - 700 specimen). The dominant families in number of species at both monitored localities family Carabid (Třebovice 9 species of Carabid, Vadkov 7 species Carabid). On the other side by carabid individuals was the activity distinctly higher in Třebovice (239 specimen carabid) than in Vadkov (38 specimen carabid). Adaptable species (RII 13 species) prevailed over expansionnists (E 5 species) in both localities. In the locality Třebovice was found 29.4% expansive species (E) against the area Vadkov 18.2% expansive species (E). Species that are tied to the habitats moderately influenced by man, known as relics of the second order (RII), in the vicinity of Třebovice occurred in 70.6% and in 81.8% Vadkov. Groups relics of the first order (RI) in the monitored areas were not detected. Index of human impact showed slightly better values at locations on the outskirts of Blanský les (Vadkov) (50%) than in the military area Třebovice (49,17%). Greater species diversity (Třebovice 16 species, Vadkov 11 species) and abundance (Třebovice 726 specimen, Vadkov 700 specimen) of beetles was in fond in the military area. This demonstrates that military area Boletice habitats are important for the survival of many species and serves as a source of biodiversity for neighboring stations.
