The objective of the study was to provide the useful scientific data m the early rehabilitation of the legging road after timber harvesting in the forest area. This study teas carried out at logging roads which were constructed daring 1989 and 1994 in Mt. Baekwoon. The field survey was conducted in July. 1991. Judging from the analysis of soil bulk density, time required for recovery as the undisturbed forest soil condition was more than 10 years in the road which was left, and the regression equation is as follows, Y₁=1.4195-0.0744·X(R²=0.91) Y₂=1.4673-0.0688·X(R²=0.73) (X : elapsed year after road construction. Y₁,Y₂: soil bulk density(g/㎤) at 0∼7.5㎝, and 9.5∼15.0㎝, respectively) Especially soil bulk density with buffer strip-woods was 0.890-0.903g/㎤, so it was 20% lower than that of logging road surface without buffer strip-woods Among the 7 factors, location, sand content, and soil hardness had statistically significant effect on the soil bulk density in logging road surface The pioneer species on logging road surface were Rhus cratargifolius, Prunus chinensis, and Lespedeza cytobotrya, etc. in wood.s species, and Pteridium aquilinum. Arundinella hirta, and Lysimachia clethroides, etc. in herb species. So, in process of year, average plant coverage were 70% on cutting and banking slope and 20% on logging road surface which elapsed 6 years after logging road construction. Through this research buffer strip-woods must be remained for environmental conservation of forest conditions, and from the tune to be closed the road, planting, seeding, and grazing works could be effective to the soil condition and vegetation recovery.
