ABSTRACT

This study was conducted to obtain information relevant to resolving problems related to artificially introduced plants in ecological restoration projects. We investigated artificially introduced plants and plants growing naturally from its surroundings in the active restoration sites of the Ecosystem Conservation Fund Return Project (ECFRP) of the Ministry of Environment and the Civilian Control Zone Forest Restoration Project (CCZFRP) of the Korea Forest Service. We also analyzed the characteristics of native, exotic, and cultivated plants in addition to their Raunkiaer’s life forms. Furthermore, we compared the planted areas and inhabited areas, as well as the characteristics of the habitats of native plants among the planted plants. We found that among the plants planted in the ECFRP, 50.4% were native, 6.8% were exotic, and 42.9% were cultivated. Meanwhile, in the CCZFRP, 78.6% were native, 21.4% were exotic. We also noted that many native plants were found in the planted areas that were far from their habitats. In addition, we identified many native plants that were planted in areas judged to have characteristics different from that of their natural habitat. In the case of Raunkiaer’s life forms, the planted plants showed high ratios of megaphanerophytes (MM) and microphanerophytes (N), while the invasive plants showed high ratios of therophytes (Th) and hemicryptophytes (H). When restoring the ecosystem, the ratio of planting native plants should be higherthan that of exotic or cultivated plants. Moreover, the habitats and ecological characteristics should be considered when selecting native plants to enhance the effect of ecological restoration.
