Abstract

Hwangmaesan Mt. (1,108 m) is rich in forest biodiversity and is a part of the Sobaek mountain range located in Hapcheon-gun, Gyeongsang-do in Korea. Unfortunately, the biodiversity and ecosystem integrity of Hwangmaesan Mt. have recently been threatened by heavy human disturbances. We conducted thirteen field surveys between March and October of 2019 to investigate the vascular flora in Hwangmaesan Mt. Through this extensive survey, we found 628 taxa consisting of 106 families, 349 genera, 554 species, 16 subspecies, 48 varieties, and 10 forma. Based on a comparative analysis between the present findings and former flora reports, our results showed an increase by 28 percent in the number of taxa observed. Of the 628 taxa, dicotyledons made up the largest group (477 taxa, 76.0%) followed by monocotyledons (120 taxa, 19.1%). Endemic plants consisted of 16 taxa, with rare plants designated by the Korea Forest Service numbering 14 taxa. Ten taxa were listed on the Red list by the Ministry of the Environment. The floristic target species designated by the Ministry of the Environment numbered 75 taxa, whereas there were 42 taxa of invasive plants.

경상남도 합천군과 산청군의 경계에 위치한 황매산(1,108 m)은 소백산맥의 줄기로 식생이 풍부하고 산림생물다양성이 높다. 그러나 지속적인 개발 및 등산객 등 관광객 증가와 함께 외래식물의 유입, 식재로 인한 생태계 교란 등의 문제가 우려되고 있다. 본 연구는 황매산의 관속식물상을 파악하여 현재의 기록을 남기는 동시에 식물다양성 보존 방안 및 외래식물의 산림 내 추가유입 방지를 위한 기초자료로 활용하고자 계획되었다. 조사는 2019년 3월부터 동년 10월까지 13회에 걸쳐 계절별로 개화하는 식물을 채집하고, 기록하는 방식으로 이루어졌다. 조사 결과, 기존 조사에 비해 약 28%의 분류군이 증가한 106과 349속 554종 16아종 48변종 10품종의 총 628분류군을 확인하였다. 이는 국내 관속식물 4,364분류군의 14.4%에 해당되며, 이중 양치식물이 26분류군(4.1%), 나자식물이 5분류군(0.8%), 쌍자엽식물이 477분류군(76.0%), 단자엽식물은 120분류군(19.1%)으로 분류되었다. 조사된 분류군 중 특산식물은 16분류군, 산림청지정 희귀식물은 14분류군이었고, 침입외래식물은 42분류군, 환경부 지정 식물구계학적 등급종은 75분류군으로 나타났다.
