The purpose of this study is to provide the baseline data for conservation and management of the ecosystem of urban forest by surveying and analysing the vascular plants distributed in Hwangseong Park, Gyeongju-si. The results of the survey of vascular plants from April 2018 to May 2020 were summarized as 338 taxa including 78 families, 222 genera, 296 species, 5 subspecies, 18 varieties, 6 forms, 4 hybrids and 9 cultivars, and 110 taxa of planted species and 235 taxa of native species were identified. The representative planting species was Liriope muscari. The 7 taxa of rare plants and 5 taxa of Korean endemic plants were investigated. The specific plants by floristic region were totally 24 taxa, which were 1 taxa of grade V, 4 taxa of grade IV, 7 taxa of grade III, 4 taxa of grade II and 8 taxa of grade I. The 57 taxa of naturalized plants and 6 taxa of invasive alien plants were showed. In particular, Chionanthus retusus represent traditional landscape trees in Korea and have high ecological value. Therefore, the old trees of Chionanthus retusus will have to be managed by assigning a number for each individual. The invasive alien plants will need periodic control and development of programs that can work in conjunction with civic groups.

We investigated the area around four moors from May 2009 to June 2010 for plant diversity in Moojechineup, officially designated as the Ramsar wetland. The vascular plants of Moojechineup at Mt. Jeongjok were recorded as total 149 taxa, 55 families, 105 genera, 128 species, 1 subspecies, 16 varieties, and 4 forms. Rare plants were observed 7 taxa (Eriophorum gracile Koch, Drosera rotundifolia L., Iris ensata var. spontanea (Makino) Nakai, Kobresia bellardii (All.) Degl, Utricularia bifida L., Utricularia racemosa Wall., Utricularia yakusimensis Masam.). Korean endemic plants were 1 taxon, floristics special plants were 19 taxa, and naturalized plants were 3 taxa. Phytogeographical and evolutionarily, Eriophorum gracile is an important species; hence, further studies are needed to conserve it. Moojechineup is similar to the Shinbulsan wetland in terms of wetland plants (hydrophytes). Moojechineup's flora changes are in process slowly compared to earlier work; thus, continuing interest and appropriate measures should be encouraged.
