Background: Cakile edentula (Bigelow) Hook. is a successful invader that has been propagating globally. In Korea, Cakile edentula was found in 2008 for the first time, in the east coast of Korean peninsula. Based on site surveys conducted thereafter, Cakile edentula has propagated in the east coast from Goseong to Jeongdongjin, Gangneung and in the west coast of city of Hwaseong of Gyeonggi-do Province, and Taeangun County of Chungcheongnam-do Province. Results: Cakile edentula has infiltrated into four different vegetation communities (syntaxa) (Calystegio soldanellaeSalsoletum komarovii Ohba, Miyawakiet Tx.1967; Elymo-caricetum Kobomugi Miyawaki 1967; Carex pumila; and Calystegia soldanella) belonging to phytosociological classes of saltwort (barilla) and coastal glehnia. Cakile edentula competes with dominant species such as the saltwort (barilla) and beach morning glory, causing qualitative changes in species composition. It also affects local ecosystems through its competition with indigenous species, causing destruction of the traditional landscape. Conclusions: However, competition of Cakile edentula with indigenous species and the resulting replacement of such species are limitedly reported. Potential competitors with Cakile edentula have not been found yet. In Northeast Asia, qualitative changes realized in local ecosystems due to invasion of Cakile edentula are significantly noticeable. These necessitate proper controls for this invasive alien species to protect and preserve coastal dune areas.

This study was conducted to evaluate the vegetation structure of community by the phytosociology method, floristic composition table on coast of South Korea. Form 2007 June until November, $2m{\times}2m$ quadrat was established in native Glehnia littoralis in order to record a dominants and coverage, and it drew the profile. It was found out that the mean temperature in the distributed areas for Glehnia littoralis population was $11^{\circ}C$ or more. The flora of the studied area in Glehnia lottoralis community of coastal dune was listed as 100 species. Glehnia lottoralis community of appearance species of Yeonggwanggun Duwori was many most by 44 species. Carex pumila, Carex Kobomugi, Imperata cylindrica var. koenigii, Ischaemum anthephehoroides and Vitex rotundifolia range all over the studied areas. And the vegetation of Glehnia littoralis community was classified into Vitex rotundifolia subcommunity, Ischaemun anthephephoroides subcommunity and Imperata cylindrica var. koenigii subcommunity. Native Glehnia littoralis was classified into preserve area, natural selection area and artificial destruction area. It must preserve native Glehnia littoralis of Goseong, Yeongdeok, Haenam it was ecological important area.
