This study was carried out to investigate the distribution of native Asparagus cochinchinensis and ecological characteristic in South Korea. Natural vegetative areas were investigated at 5 areas; Taean, Buan, Geoje, Namhae and Jindo. In this study, the $5m{ imes}5m$ quadrat was established for recording coverage and appearance species by phytosociological method. The flora of the studied area in native habitats were listed as 130 species. The native habitats was classified into Pinus thunbergii community and typical community. Two communities were located in a coastal cliff and have been destroyed. Therefore Asparagus cochinchinensis native habitats must be protected by regulation. In the studied sites, soil pH, organic matter, nitrogen, available phosphorus, exchangeable K, exchangeable Ca, exchangeable Mg and cation exchange capacity were ranged from $5.1{sim}5.7%$, $1.77{sim}3.59%$, $0.19{sim}0.54%$, $5.4{sim}18.7$ (mg/kg), $0.24{sim}0.48$ (cmol+/kg) $0.76{sim}2.83$ (cmol+/kg), $3.11{sim}6.22$ (cmol+/kg) and $8.7{sim}24.5$(cmol+/kg), respectively.
