The Flora of Limestone Area, Mt. Seokbyeong

Abstract

-This study was carried out to survey the vascular plants on Mt. Seokbyeongsan (1,055 m) and provide a basis for the conservation and management of plant resources. The vascular plants were surveyed from March to October 2015. The flora on Mt. Seokbyeongsan was classified as follows: 102 families, 295 genera, 454 species, 4 subspecies, 51 varieties, 7 forms, and a total of 516 taxa. Endemic plants included 17 families, 24 genera, 25 species, 1 variety, and a total of 26 taxa. The Korea Forest Service assignment of rare plants, including 21 families, 33 genera, 33 species, 3 varieties, and a total of 36 taxa, was investigated. Moreover, the Ministry of Environment assignment of rare plants, including 13 families, 17 genera, 17 species, 1 variety, and a total of 18 taxa, was investigated. Floristic special plants in the surveyed area were divided into five classes (Classes Ⅰ-Ⅴ): 42 taxa of Class Ⅰ, 26 taxa of Class Ⅱ, 35 taxa of Class Ⅲ, 20 taxa of Class Ⅳ, and 9 taxa of Class Ⅴ for a total of 132 taxa. Naturalized plants were 18 taxa, and plants threatened by climate change were 48 taxa. Key words -

The complete chloroplast genome sequence of the medicinal plant, Dracocephalum rupestre (Lamiaceae)

“…Populations of Korean D. rupestre are restricted to small areas at the southern limit of their geographical distribution (Song et al. 2016 ; Kim et al. 2018 ).…”

A checklist of vascular plants in limestone areas on the Korean Peninsula

“…우리나라의 석회암 지대에서도 비석회암지대와 다른 식생뿐만 아니라 고산 식물의 격리 또는 북방계 희귀식물들의 분포, 그리고 석 회암이라는 특수한 생육환경에 고립 및 적응하여 새로운 종분화가 일어나는 등의 특성이 이를 뒷받침한다 (Kim et al, 2005;Korea National Arboretum, 2012;Nam et al, 2012). 이러한 식물지리학적 특이성으로 인해 여러 생태분류학 자들에게 연구중심의 대상지가 되었으며 (Chung, 1994;Hong and Im, 1997;Kim et al, 2005;Korea Teacher′s Plant Research Association, 2011;Moon et al, 2013;Oh, 2013;Nam et al, 2014;Song et al, 2016;Chae et al, 2019;Park et al, 2020), 최근까지도 신종 및 미기록종 등의 식물이 지속적으 로 발견되고 있다(National Institute of Biological Resources, 2011Resources, , 2017. 그러나 생태계 다양성의 중요한 지역임에도 불구하고 석회석 생산이라는 명분아래 일부 석회암지대 의 산지 대부분은 소실되어 그 원형을 알아보기 힘들고 생태학적 기능은 상실된 상태이다.…”

“…석회암지대 호석회성 식 물의 선정 기준은 다음과 같다. 첫째, 지표종(calciphilous 1), 석회암지대 10개 지역(도담삼봉 (Chung, 1994), 자병산 (Hong and Im, 1997), 덕항산 (Kim et al, 2005), 각희 산(Korea Teacher's Plant Research Association, 2011), 응봉 산 (Moon et al, 2013), 석문봉 (Oh, 2013), 면산•묘봉 (Nam et al, 2014), 석병산 (Song et al, 2016), 동강 (Chae et al, 2019), 대덕산•금대봉 (Park et al, 2020)), 인근의 비석회암지대 10 개 지역(공덕산 (Chung et al, 2008), 갈라산 (Chung et al, 2010), 청태산 (Ji et al, 2011), 흥정산 (Han et al, 2012), 청량 산 (Nam et al, 2015), 백암산 (Cheon et al, 2016), 자암산 (Kim et al, 2019), 부용봉(National Institute of Biological Resources, 2019b), 무이산(National Institute of Biological Resources, 2020), 구룡산 (Sung et al, 2019))이다. UPGMA (Unweighted Pair-Group Method using Arithmetic averages) 방법으로 군 집분석을 수행하였고, Sørensen의 유사도 지수(similarity (Kim et al, 2005;Korea National Arboretum, 2012;Nam et al, 2012).…”
