In recent, habitat fragmentation is one of the major factors to threat to biodiversity loss, because habitat fragmentation caused by urbanization and land-use change affect reducing of habitat amount and changing of environmental condition. In particular, increasing of forest edges by habitat fragmentation cause changing of microclimate and distribution of organisms in forest. This study was conducted to examine the distributional patterns of ground beetle assemblages along forestedge- crop gradients in Hoengseong-gun, Gangwon-do. We selected 8 study sites as line gradients from forest interior to crop (+80m, +40m, +20m, 0m, -20m, -40m, -80m). Ground beetles were collected by pitfall traps from May to October in 2012. A total of 61 species were identified from 3,739 collected beetles. Species richness was the highest at forest edge (GLM with Tukey’s test, F6, 49=2.56, P=0.031). Although abundance was higher at both forest interior and edge, but not showed statistical significance (F6, 49=2.06, P=0.076). Species composition of forest interiors were significantly different from forest exteriors (crops) by non-metric multidimensional scaling (NMDS) and cluster analysis with similarity profile test (SIMPROF), while forest edges showed intermediate characteristics. Although our study sites may not represent the overall Korean forest, we confirmed that forest edges are important habitats for generalists and open-habitat species as well as forest specialists. In conclusion, management of both forest edge and its surroundings are needed to conserve biodiversity in forest,
