Naturalized plants were identified and recorded in Busan city based on field surveys and related literature. These plants consisted of 156 taxa in total, belonging to 31 families, 95 genera, 147 species, and 9 varieties. The Compositae had the highest diversity among 31 families, with 44 taxa, followed by Gramineae, with 24 taxa, and Leguminosae, with 10 taxa Among the plants, 68.6% (107 taxa) were annuals and biennials, and 30.1% (47 taxa) were perennials. There was one shrub (Amorpha fruticosa) and one tree (Robinia pseudoacacia). Naturalized degree 5 plants, as common and abundant plant, founded 26 taxa (96.3%) were most highly ratio from Korean naturalized plants. According to the results of the analysis based on place of origin, 50 (32.1%) taxa were from Europe, and 48 (30.8%) taxa were from North America. Epecophyten was the most common of the naturalized plants, with 123 taxa Sixty-six (42.3%) taxa were introduced during period 1, and 15 (9.6%) were introduced during period 4. Ergasiophygophyten (50.6%) and Kenophyten (32.1%) were the dominant plants in these introduction periods. In conclusion, Busan city acts as a conduit for the introduction of naturalized plants. A sustainable management and monitoring strategy may be needed to prevent the introduction and naturalization of plants.

The life form, the origin and the time of introduction of those naturalized plants grown in Jeju-Do, korea were grasped by conducting the documentary survey, and the field survey thereof. The naturalized plants were total 199 taxa including 185 species, 12 varieties and 2 cultivar, which belong to 115 genera, 32 families. The classification of families, there were 43 taxa of Compositae ($21.6\%$), 32 taxa of Gramineae ($16.8\%$), 17 taxa of Legumlinosae ($8.5\%$), and 13 taxa of Cruciferae ($6.5\%$). As the life forms of the naturalized plants in Jeju Island were there 91 taxa of annual plants, 31 taxa of biennial plants, 16 taxa of annual or biennial plants, 57 taxa of perennial plants, and 4 taxa of trees. The distribution of the naturalized plants, the were 29 taxa thereof were located in Jeju Island, 20 taxa in Jeju Island as well as in the southern part of Korean Peninsula, 33 taxa in Jeju Island as well as in the central part of Korean Peninsula, and 117 taxa in the entire area of South Korea. As 89 taxa thereof were originated from America, 69 taxa from Europe, 2 taxa from Africa, 22 taxa from Asia, 1 taxa from Oceania, and 16 taxa from other provinces. As 38 taxa thereof had been introduced into Jeju Island before 1921, 23 taxa from 1922 to 1963, and 138 taxa since 1964.

This study was carried out to present raw data on managing the restored urban stream by studying the naturalized plants distributed in Gaeumjeong Stream, Changwon-si, Gyeongsangnam-do, Korea. The results were as follows. The numbers of naturalized plants were summarized as 45 taxa including 17 families, 36 genera, 43 species and 2 varieties. The invasive alien plants were 2 taxa including Ambrosia artemisiifolia and Lactuca sativa. The following summarizes the attributes of the naturalized plants. Most of the plants commonly originated from Europe and North America. The 5 naturalized degree that was widely distributed and had many individual was the most common. Until 1921, after the opening of 1 period was the most common in the introduced period. Section 12 had the highest NI at 41.9%, and the lowest, at 20.5%, in sections 9 and 19 were analyzed. Section 1 had the highest UI at 6.2%, whereas, the lowest, at 2.5%, was calculated in sections 19 and 20. Section 2 showed the highest DI at 16.7%. The first results of the analysis of the causes for the invasion of naturalized plants on the riverside and waterways, and physical factors and maintenance are directly affected. Second, sewage, muddy water and sediment deposits this naturalized plant caused by a chemical factor. Third, it is thought that invasive alien plants are irregular as it happens in biological factor. The proposed management plan naturalized plants, the first, disturbance caused by species management is a young object is removed immediately before flowering scape to eliminate or suppress the propagation of physical methods will be needed. Second, the fact that the national spread of native plant species and planting management does not provide space for the growth is very important. Third, agricultural land is disturbed by agricultural practices by interfering with the action of naturalized plants because the source of the river should be prohibited in agriculture. In the future, if we studied the naturalized plants distributed in restored streams located in Changwon-si, the characteristics of change in the ecosystem impact is expected to be beneficial.
