For providing basic data on estuary conservation and pattern of vegetation succession of sand bar, the flora of delta was investigated from March 2004 to August 2006 in the Nakdong River estuary of Korea. The flora in the eight surveyed areas was composed of total 159 taxa that belonged to 46 families, 123 genera, 133 species, 1 subspecies, 20 varieties, and 5 forms. Among them, naturalized plants and evergreen broad trees were 31 taxa and 5 taxa, respectively. The communities of main species at delta of estuary were composed of 16 species such as Rosa rugusa community, Scirpus triqueter community, Phragmites communis community, Carex kobomugi community, Digitaria ciliaris community. Especially, Rosa rugusa community which are important to establish the southern limit line of distribution as the northern factor was distributed through Jinwoodo. The succession of main vegetation community in the new delta (Doyodeung) was in order of Carex scabrifolia, Scirpus triqueter, Phragmites communis, Imperata cylindrica var. koenigii and Miscanthus sinensis var. purpurascens. Therefore, the succession order of the surveyed area seems to predict the pattern of the vegetation succession of another deltas in Nakdong River estuary.
