Abstract

The purpose of this study is to collect the raw data for conservation of plant ecosystem by surveying and analysing the flora of Mt. Geumgok located in Gyeongju-si, Gyeongsangbuk-do, Korea. The flora were summarized as 453 taxa including 91 families, 298 genera, 397 species, 4 subspecies, 46 varieties and 6 forms. The rare plants designated by Korea Forest Service were 3 taxa such as Eranthis byunsanensis B.Y.Sun, Potentilla discolor Bunge and Iris odaesanensis Y.N.Lee. The Korean endemic plants were 6 taxa such as Carpinus laxiflora (Siebold & Zucc.) Blume, Eranthis byunsanensis B.Y.Sun, Philadelphus schrenkii Rupr., Lespedeza maritima Nakai, Vicia chosenensis Ohwi and Weigela subsessilis (Nakai) L.H.Bailey. The specific plants by floristic region were 36 taxa such as Pinus koraiensis Siebold & Zucc., Salix chaenomeloides Kimura, Anemone raddeana Regel, Chloranthus japonicus Siebold, Euphorbia pekinensis Rupr., Ilex macropoda Miq., Ajuga multiflora Bunge, Saussurea odontolepis Sch.Bip. ex Herd, Viola orientalis (Maxim.) W.Becker, Betula davurica Pall., Vitex negundo var. incisa (Lam.) C.B.Clarke and Cimicifuga heracleifolia Kom.. The naturalized plants were 36 taxa such as Fallopia dumetorum (L.) Holub, Lepidium apetalum Willd., Robinia pseudoacacia L., Trifolium repens L., Euphorbia supina Raf., Ipomoea purpurea Roth, Veronica persica Poir., Bidens pilosa L., Carduus crispus L., Xanthium canadense Mill., Bromus unioloides H.B.K. and Festuca arundinacea Schreb.. The invasive alien plants were 2 taxa such as Ambrosia artemisiifolia L. and Aster pilosus Willd.. The ratios of the urbanized index(UI), the naturalized index(NI) and the disturbed index(DI) were 11.2%, 7.9% and 18.2% each.
