The rapid increase of naturalized plants causes disturbance of the ecosystem. The purpose of this study is to identify the reality of naturalized flora in Jeolla-do. A total of 830 sites were studied in 2016. These naturalized plants consisted of 189 taxa in total, belonging to 38 families, 116 genera, 181 species, 2 forms and 6 varieties. According to the results of the analysis based on place of origin, 75 taxa were from Europe, and 59 taxa were from North America. According to the analysis of the ecological characteristics, compositae had the highest diversity among 31 families, with 44 taxa, followed by Gramineae, with 24 taxa, and Leguminosae, with 10 taxa. Naju-si had the highest diversity among 36 counties, with 77 taxa. This study identified 37 (Jeollanam-do) and 30 taxa (Jeollabuk-do) not listed in the preceding literature in Jeolla-do. We found a lots of differences between flora's databases of previous studies resulting from the naturalized plant definition.
