This study was to evaluate the growth and spatial distribution characteristics of Rhus javanica population. The study was conducted between 2015 January and July at the cut-slope revegetation site in Dae-Ji Mountain. Seeds of native species were sowed on the disturbed cut-slope in 2002. There were 119 vascular plant species 55 families and 94 genera on the cut-slope. Compositae, Rosaceae, and Leguminosae plants were dominant species, which are pioneer species in dry and barren site. Canopy of trees covered 44.1% total area, which was 8.3% increase from 2008. Rhus javanica, main species, dominated all DBH classes except DBH >24cm. Albizzia julibrissin showed high frequency in the 6~17cm DBH class and Salix koreensis was abundant at >12cm. Elaeagnus umbellata, Corylus heterophylla var. heterophylla, Alnus sibirica, and Acer pictum were not observed. Rhus javanica population was the most frequently observed on the south facing cut-slope. The average DBH of Rhus javanica was and the average height of them was . Annual average DBH growth was 7.9mm/yr and the maximum growth(12.0mm/yr) was the year. It decreased after years. Although Rhus javanica population in the Dae-Ji Mountain was a seed originated plantation, the forest had reverse J shape diameter frequency distribution. It indicated that the forest is uneven-aged forest. The Rhus javanica population was expected to sustain.
