This study was conducted to investigate the community structure and species distribution of ground beetle assemblages in western part of Yeongwol-gun, Korea. Ground beetles were collected by pitfall traps from 9 study sites during July to October in 2013. A total of 30 species were identified from 4,439 collected ground beetles. Two dominant species, Synuchus nitidus (1,916 individuals) and Synuchus cycloderus (1,900 individuals) were occupied 85.8% of total. Interestingly, Pterostichus orientalis orientalis and Synuchus melantho were only collected in relative high altitude above 350 m, such as Beopheung-ri, Unhak-ri, and Yongseok-ri. Large-sized beetles, such as Damaster, Leptocarabus, and Carabus species, were generally more collected from Suju-myeon (Beopheung-ri and Unhak-ri) and Jucheon-myeon (Docheon-ri and Yongseok-ri) as well-conserved area, but not occurred in Yeongwol-eup and Hanbando-myeon, which forests may have lower habitat quality for these species. These differences also lead to increasing of dissimilarity among study sites, which were diverged into 3 groups at 53.0% of similarity. In particular, species composition of Samok-ri was significantly different at 8.2% of similarity because of difference in habitat characteristics as river side. This study has an important value to provide the fundamental information of inventory and monitoring in Yeongwol-gun. For detail mapping of species distribution in Yeongwol-gun, however, further studies are necessary, especially eastern parts of Yeongwol-gun.
