This study was carried out to identify the relationship between naturally introduced vegetation on theabandoned coal mine lands and the surrounding forest, and to select the indigenous tre species forthe revegetation of the coal mine lands in Taeback, Kangwon Province, Korea. The aparent species inthe surrounding forest of Sododong were 9 species of tre layer, 13 species of subtree layer, 23 speciesof shrub layer and 23 species of herb layer, respectively. The dominant species in Sarijae were 6species of tree layer, 15 species of subtre layer, 31 species of shrub layer and 25 species of herb layer,respectively. The plant species in the abandoned coal mine land were 31 species in Sododong and 30species in Sarijae, respectively. The number of plant species in the abandoned coal mine land wassmaller than the surrounding forest. The comon species of the coal mine lands and the surroundingforest were 6 species(Betula schimidtii etc.) in Sododong and 4 species(B. costata etc.) in Sarijae. It wasconsidered that the species in the coal mine lands introduced from the species of top layer in thesurounding forest. Especially, B. costata in Sarijae showed the edge effect, which regenerates thevegetative comunity from the boundary area of coal mine land and surrounding forest. Naturalrevegetation in Sododong was also progressing by the invasion of tre species in surrounding forest,such as B. schmidtii. Consequently, natural revegetation in the disturbed coal mine lands may berelated to the species composition of the surrounding forest.
