Abstract

This study conducted a survey on flora at Mt. susdolbon(508m), Mt. seongjubong (625.3m), and Mt. sulibong(596.2m), located in Yanggu-gun, Gangwon-do. A total of 403 taxa, including 6 forms, 43 varieties, 4 subspecies, 350 species, 255 genera, and 84 families, were surveyed in the three mountain areas. 18 taxa from 5 families of ferns, 3 taxa from 1 family of gymnosperms, and the dicotyledonous plants as 302 taxa from 69 families of the dicotyledonous plants were identified. The remarkable plants included 11 taxa of the Korean endemic plants, such as Populus tomentiglandulosa, Salix koriyanagi, Cimicifuga heracleifolia, Aconitum pseudolaeve, Clematis trichotoma, Echinosophora koreensis, Vicia chosenensis, Salvia chanryoenica, and Hemerocallis hakuunensis. The rare plants designated by the Korea Forest Service were 4 taxa, including Echinosophora koreensis as endangered species (EC), Cimicifuga heracleifolia, Epimedium koreanum, and Lilium cernuum. The Least Concern species (LC) were 13 taxa, including Persicaria orientalis, Exochorda serratifolia, Viola diamantiaca, Lithospermum erythrorhizon, and Trigonotis icumae. The invasive alien plants were 28 taxa, including Persicaria orientalis, Rumex crispus, Phytolacca americana, Cerastium glomeratum, Chenopodium album, Chenopodium ficifolium, Amorpha fruticosa, Robinia pseudoacacia, Trifolium pratense, Trifolium repens, Oxalis dillenii, Euphorbia supina, and Oenothera biennis, accounting for 6.9 percent of the 403 taxa of the surveyed plants.

본 연구에서는 강원도 양구군에 위치한 숫돌봉(508m), 성주봉(625.3m), 수리봉(596.2m) 지역을 중심으로 식물상 조사를 실시하였다. 3개 산지 식물상 조사결과, 84과 255속 350종 4아종 43변종 6품종으로 총 403분류군의 관속식물이 조사되었다. 분류군별로는 양치식물이 5과 18분류군, 나자식물이 1과 3분류군, 쌍자엽식물이 69과 302분류군, 단자엽식물이 9과 80분류군으로 확인되었다. 주요 식물은 특산식물이 은사시나무, 키버들, 세잎승마, 진범, 등 총 11분류군, 산림청 지정 희귀식물은 위기종(EN) 개느삼 등 1종 취약종(VU) 세잎승마, 삼지구엽초, 솔나리 등 총 4분류군이 확인되었다. 약관심종(LC) 도깨비부채, 가침박달, 태백제비꽃 등 총 13분류군이 확인되었다. 침입외래식물은 털여뀌, 소리쟁이, 미국자리공, 유럽점나도나물, 흰명아주, 좀명아주, 족제비싸리, 아까시나무, 붉은토끼풀, 토끼풀, 들괭이밥, 애기땅빈대, 달맞이꽃 등 총 28분류군으로 조사되어, 조사식물 403분류군의 6.9%를 차지하였다.
