The Floristic Study in the Northern region on Mt. Deogyu National Park

Abstract

From March to November, 2003, Flora in northern area of Mt. Deogyu was investigated for 44 units of investigation lattice established in a unit of 2×2 km over 9 times. As the result, it was found that total 591 taxa such as 97 families, 349 genera, 511 species, 63 varieties, and 7 forms were certified. The appearing plants by investigation lattices include from minimum 22 taxa to maximum 155 taxa and the mean value in the whole lattices was 87 taxa. In addition, it was found that the plants collected and certified in the area of Mt. Jeocksang were total 294 taxa such as 77 families, 191 genera, 261 species, and 33 varieties. The specific plants certified during this research period were 82 taxa which comprised 46 families, 70 genera, 80 species, 2 variaties. It was found that among them, V grade were 2 taxa such as Cimicifuga heracleifolia KOM., and Acanthopanax senticosus (Rupr. et Max.) HARMS, IV grade were 2 taxa such as Anemone narcissiflora L., and Lonicera chrysantha TURCZ, III grade were 13 taxa. II grade were 20 taxa such as Lilium distichum NAKAI, Caltha palustris var. membranacea TURCZ. and Phellodendron amurense RUPR., and I grade were 43 taxa such as Botrychium virginianum (L.) SW., and Cephalotaxus koreana NAKAI. Exotic plants appeared in the investigation regions were 9 families, 18 genera, and 21 taxa, and it was found that the ratio of naturalized plats among the total appearing plants was 3.3%.
