Abstract
Topsoil of Quercus variabilis-domninated secondary forest was spread on a cut slope for revegetation in a developing new town area in urban Osaka. For seedling observation, seventy-five subplots(1 m×1 m) in a cut slope plot, 300 subplots(1 m×1 m) in the Quercus stand plot were established. We recorded species and number of woody seedling. Forty-three species and 807 seedlings in the Quercus plot, 48 species and 1,105 seedlings in the cut slope plot were observed. The numbers of pioneer seedlings in the cut slope plot were significantly higher than in the Quercus plot. The numbers of seedling of Caprifoliaceae, Aquifoliaceae, Cornaceae and Theaceae were significantly higher in Quercus plot than in the cut slope plot. So it appears that these species have difficulty to emerge on a slope where soil is liable to dry condition.
