Abstract

This study was conducted to investigate the vascular flora of Masan, located in Goseong-gun, Gangwon-do, and to comprehend the distribution of remarkable plants such as rare and Korea endemic plants and invasive alien plants. The survey was carried out the distribution of vascular plants 11 times per season from 2010 to 2018. A total of 619 taxa in 93 families, 328 genera, 529 species, 6 subspecies, 78 varieties and 6 forms were identified on mt. Masan. Among them, Korean endemic plants are 21 taxa including Saussurea diamantica Nakai and are plants designated by the Korea Forest Service are 20 taxa counting Saxifraga octopetala Nakai. Invasive alien plants were classified a total of 35 taxa inclusive of Trifolium pratense L. (WS), Aster pilosus Willd. (SS), Coreopsis lanceolata L. (SR), Rumex obtusifolius L. (SC) and Lindernia dubia (L.) Pennell (CS). The naturalization rate was 5% and the urbanization index was 10.0%, respectively. Although this study identified the diverse distribution of major plants such as rare and endemic plants around Masan, it was confirmed that invasive alien plants, which pose a great threat to forest biodiversity conservation and promotion, spread and distributed in a specific section Therefore, it is urgent to establish a conservation strategy and countermeasures.

본 연구는 강원도 고성군에 위치한 마산의 관속식물상을 조사하고 희귀·특산 식물 등 주요 식물과 침입외래식물의 분포를 파악하고자 수행되었다. 조사는 2010년부터 2018년까지 계절별 총 11회에 걸쳐 관속식물 분포를 조사하였다. 조사를 통해 확인된 관속식물은 총 총 93과 328속 529종 6아종 78변종 6품종 619분류군이 자생하는 것을 확인하였다. 이 중 한국 특산식물은 금강분취(Saussurea diamantica Nakai) 등 21분류군, 산림청지정 희귀식물 중 위기종(EN)은 구실바위취(Saxifraga octopetala Nakai) 등 2분류군, 취약종(VU)은 천마(Gastrodia elata Blume) 등 3분류군, 약관심종(LC)은 세잎종덩굴(Clematis koreana Kom.) 등 15분류군 등 총 20분류군의 희귀식물이 확인되었다. 침입외래식물은 광분포(WS) 등급은 붉은토끼풀(Trifolium pratense L.) 등 12분류군, 심각한 확산종(SS)은 미국쑥부쟁이(Aster pilosus Willd.) 등 8분류군, 확산위험종(SR)은 큰금계국(Coreopsis lanceolata L.) 등 4분류군, 확산우려종(SC)은 돌소리쟁이(Rumex obtusifolius L.) 등 6분류군 및 확산진행종(CS)은 미국외풀(Lindernia dubia (L.) Pennell) 등 5분류군, 총 35분류군으로 파악되었다. 귀화율은 5%, 도시화지수는 10.0%로 각각 나타났다. 본 연구를 통해 마산 주변에서 희귀·특산식물 등 주요식물이 다양하게 분포하고 있는 것을 파악하였으나, 산림 생물다양성 보전 및 증진에 큰 위협이 되는 침입외래식물이 특정 구간에서 집중적으로 확산하여 분포하는 것이 확인되어 보전 전략 및 대책 수립이 절실하다.
