Study on the Sod Forming Effects of the Native Plants for the Erosion Control in Slopes

This study was conducted to suggest vegetation mat forming methods with native wildflowers, introduced wild flower, grasses and native herb plants which can be used for erosion control of the disturbed slopes. The main results are summarized as follows. In forming the vegetation mat at early stage, foreign grasses, native wild plants shows more effective than the other seed mixture types. But, after 12 weeks, using native wild flowers shows more effective than foreign grasses. Also, the mixture of the native grasses and kentucky bluegrasses (seed mixture type F) are the best in ground coverage among the seed mixtures types. In order to restore slopes more naturally, more diverse plants should be used. The native grasses such as Marrubium incisum Bentham, Lutos comiculatus L. var. japonicus Regel, and Artemisia princeps Pampan seems to be useful to forming the vegetation mat, also it will be more easy if mixing with foreign grasses such as Kentucky bluegrass. The mixture of native grasses and introduced wild flowers are not proper in forming the vegetation mat. Also, pot planting of the native grasses are not proper in forming the vegetation mat.
