The objective of this study was to monitor vegetation recovery process after timber harvesting at (Mt.) Baekwoonsan Seoul National University Forests, Korea. Two monitoring plots were established in 1994 and woody plant were monitored in 1997, 1999, 2001, and 2003. Vegetation development pattern during last ten years (1994-2003) after timber harvesting were as follows; Styrax obassia, Styrax japonica and Lindera erythrocarpa as of the existing tree were competitive species in the first year after clear-cut, Styrax japonica and Lindera erythrocarpa as of sprout tree and Aralia elata as of seedling were dominant species in the sixth year after clear-cut, and Lindera erythrocarpa, Styrax japonica and Quercus serrata were dominant species from the eighth year to the tenth year after clear-cut. Species diversity index of harvested forest interior was decreased at the southwestern slope while it was increased in the northeastern slope till 6th year and decreased after the 8th year). According to DBH distribution pattern, No. of individuals of Quercus serrata, Styrax japonica and Lindera erythrocarpa showed high frequency in the southwestern slope, and Acer pseudosieboldianum, Styrax obassia, Magnolia sieboldii, Lindera erythrocarpa, and Aralia elata showed good growth in the northeastern slope. There was a difference between slopes in Basal area. It was decreased at the southwestern slopes during the 10th year continuously and it was increased the sixth year however, was decreased after the eighth year at the northeastern slope.
