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 80분류 군으로 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 조사 되어, 조사식물 403분류군의 6.9%를 차지하였다.

The flora of Baekseoksan was investigated from June to October, 2010. Vascular plants of investigated regions were composed of 90 families, 297 genera, 440 species, 4 subspecies, 57 varieties, and 12 forms, totally 513 taxa, and the Pteridophyta index (Pte-Q) was 1.41. Twelve taxa including endemic genus Hanabusaya among the 513 taxa were Korean endemic. Nineteen rare plants, one endangered plant and 77 specially designated plants by Ministry of Environment were also investigated. The naturalized plants were 21 taxa, and percent of naturalized plant species was 4.1%.

Mt. Bonghwa reaches a height of 800 m (2,870 ft) and stands on the flank of Mt. Daeam-san, which has an elevation of 1,304 m (4,278 ft). It is important to survey the flora of Bonghwa-san in that it is a way to make out what kind of plant species exist in DMZ due to the geographical characteristics of Bonghwa-san adjacent to Korean DMZ. Therefore this study was conducted to elucidate the distribution of vascular plants and their value of Bonghwa-san. The vascular plants that were collected 10 times from May 2015 to April 2017 consisted of a total of 525 taxa; 93 families, 309genera, 458 species, 4 subspecies, 58 varieties and 5 forms. The observed rare plant species as designated by Korea Forest Service were 12 taxa including Echinosophora koreensis, Epimedium koreanum, Anemone koraiensis etc. Endemic species were 16 taxa containing Cirsium setidens, Heloniopsis koreana, Salvia chanryoenica etc. 31 taxa were recorded as naturalized plants and their naturalized rate and urban index were noted as 5.8% and 7.25%. Among the surveyed 525 taxa, edible, medicinal, pasturing, ornamental, timber, dye, fiber and industrial plants included 213 taxa, 172 taxa, 196 taxa, 50 taxa, 23 taxa, 10 taxa, 6 taxa and 3 taxa, respectively.

This study was conducted to elucidate the distribution of vascular plants and their value of Mt. Samyeong. The vascular plants that were collected 10 times from October 2013 to July 2015 consisted of a total of 538 taxa; 92 families, 308genera, 466 species, 3 subspecies, 62 varieties and 7 forms. The observed rare plant species as designated by Korea Forest Service were 24 taxa. Endemic species were 25 taxa. 28 taxa were recorded as naturalized plants and their naturalized rate and urban index were noted as 5.3% and 8.7%. Among the surveyed 538 taxa, edible, medicinal, pasturing, ornamental, timber, dye, fiber and industrial plants included 220 taxa, 195 taxa, 167 taxa, 65 taxa, 25 taxa, 8 taxa, 6 taxa and 3taxa, respectively.
