The aim of the study was to examine communities of epigeic beetles in the plantations of fast-growing trees (poplar clone Japanese J - 105 (Jap = - 105, Max - 4, Maxvier) and surrounding habitats (Zea mays L.). A cover of Zea mays L. was used as an area for comparison. Sampling was carried out in 2012 by using the method of epigeic beetles in pitfall traps (period from May to September). During the sampling, altogether 1054 specimens and 57 species of epigeic beetles were collected. In the area of fast-growing trees ?Na Vrbovecku? 528 specimens were collected which is many times more than in other researched areas. In the cover of Zea mays L. in the area "Na Vrbovecku" 293 specimens were collected and in the zone of fast-growing trees "U rybníka" 233 specimens were catched; notice the high similarity in the number of collected specimens. At all sites surveyed the expansive species (E) outnumbered the II relics. There were about 70% of expansive species in the cover of Japanese poplar found and in the cover of Zea mays L. there were about 90% of expansive species found. The number of more adaptable species- RII category- found in the cover of Japanese poplar was approximately 30% unlike the number of the same species found inside the Zea mays L. cover was only 12%. The rare species Xantholinus gallicus of the RI category was found in the plantations of fast-growing trees "U rybníka". The index of anthropogenic impact on communities (ISD) was very low in studied plots. In the Zea mays L.cover the index was only 6 points, unlike in the cover of Japanese poplar where the index reached 24 points. Yet all researched areas show high anthropogenic impact. Based on the obtained results (epigeic beetles), it seems that plantations of fast-growing trees have a positive impact on communities of epigeic beetles in cultural landscape. Since the research was always carried out on a farmed landscape, the impact of surrounding landscape on gained results is minimal and insignificant.
