Field surveys were conducted from May 2016 to October and from April to October 2017 in Tributary Region of Middle Stream of the Nakdong River. The survey was carried out at 66 sites including Young-gang 11, Naeseong-cheon 21, Wi-cheon 16, and Gam-cheon 9, Byeongseong-cheon 9. As a result of investigation, 474 taxa in total ; 99 familly, 288 genera, 421 species, 4 subspecies, 39 varieties and 10 forma. Among them, 5 Korean endemic plants, 7 rare plants, 31 taxa were listed as Floristic Target Species in Korea. Naturalized plants was confirmed 73 taxa, their Urbanization Ratio 22.7%, and naturalization ratio 15.4% in the investigated area. The Life form(Dormancy form) review results as follows ; Therophytes 159 taxa, Hemicryptophytes 91 taxa, Hydrophanerophytes 68 taxa, Geophyte 52 taxa, Nanophanerophytes 35 taxa, Megaphanerophytes 32 taxa, Microphanerophytes 25 taxa, Chamaephytes 12 taxa, and Epiphyten 1 taxa.

This study was conducted to provide information on local resource plants by identifying aquatic and Riparian flora. We investigated the aquatic and riparian floras in 3 streams(Byeongseong-cheon, Buk-cheon, Oeseo-cheon) from February to October 2019. 321 taxa (i.e. 300 species, 5 subspecies, 15 varieties 1 Cultivars from 203 genera of 78 families) of the vascular plants were found in the survey area. Byeongseong-cheon is 133 taxa, Buk-cheon is 233 taxa and Oeseo-cheon is 132 taxa. Among 321 taxa, we found 5 endemic species, 3 red list plants, and However, endangered plants were not found in 3 streams. Aquatic and Riparian plant 138 taxa(i.e. Aquatic plant 20 taxa, Riparian plant 118 taxa). Life forms is annual plant 43 taxa, biennial plant 24 taxa, perennial plant 71 taxa. Aquatic plant growth forms emergent hydrophyte 13 taxa, floating leaved hydrophyte 1 taxa, submerged hydrophyte 6 taxa. The number of floristic regional indicator plants was 15 (i.e. 1 species of IV degree, 3 taxa of III degree, 5 taxa of II degree, and 6 taxa of I degree). Approved foreign export plants 31 taxa. In addition, 52 naturalized plants were identified, and the percentage of Naturalized Index (NI) and Urbanization Index (UI) were 16.1%, and 16.2%, respectively. Vascular plant usability and reclassification result is Edible 213 species (66%), Medicinal 244 species (76%), Flavor 10 species (3%), Industrial 136 species (42%), Ornamental 137 species (36%), Restoration 117 species (36%), Compost 155 species (48%), Unknown 7 species (5%). We hope that our results provide reference data to set up strategy of resources plants, conservation of biodiversity in the 3 streams and Sangju-si areas.
