The purpose of this study is to offer the raw data for establishing the management and restoration plan by objective surveying and analysing the flora distributed in Seoak District, Gyeongju National Park, Korea. The flora summarized as 411 taxa including 92 families, 285 genera, 363 species, 2 subspecies, 41 varieties and 5 forms. The rare plants designated by Korea Forest Service were 2 taxa including Exochorda serratifolia and Potentilla discolor. The Korean endemic plants were 3 taxa including Philadelphus schrenkii, Lespedeza maritima and Weigela subsessilis. The specific plants by floristic region were 16 taxa including Asplenium sarelii, Pyrrosia petiolosa, Vitex negundo var. incisa and so forth. The target plants adaptable to climate change were 2 taxa including Lespedeza maritima and Carpesium macrocephalum, and the plants with approval for delivering oversea were 4 taxa including Exochorda serratifolia, Glycine soja, Lespedeza maritima and Weigela subsessilis. The naturalized plants were 51 taxa including Phytolacca americana, Viola papilionacea, Lamium purpureum and so forth. The invasive alien plants were 3 taxa including Ambrosia artemisiifolia, Aster pilosus and Lactuca scariola. NI(Naturalized Index) was 12.4% of all 411 taxa of surveyed flora in this study and UI(Urbanized Index) was 15.9% of all 321 taxa of naturalized plants in Korea. Potentilla discolor in rare plant, Philadelphus schrenkii in endemic plant and Dictamnus dasycarpus in specific plant were established the conservation plan. Whereas, invasive alien plants such as Ambrosia artemisiifolia, Aster pilosus and Lactuca scariola should be removed as soon as possible. The damaged sites in Seoak District were divided between wildfire area and farmland. To restore a forest fire site, we will have to apply a natural renewal and community planting. In case of farmland, we will have to do ecological planting using native species and constrcut a forest wetland.

우리나라의 아고산대는 기후변화에 지역적 취약성을 띄는 지역으로, 아고산대의 산림식생은 기후변화에 따른 영향을 관찰할 수 있는 중요한 기초지표 중 하나이다. 본 연구는 지리산 아고산대의 기후변화 취약수종 분포지의 산림식생을 대상으로 하여 식물사회학적 식생 유형 및 희귀-특산식물 분포 특성에 대해 구명하였다. 2015년 3월부터 10월까지 37개소에서 식생조사를 실시하였고, 식물사회학적 식생유형 분류를 통해 종조성을 파악하고, 종의 우점도를 파악하기 위해 중요치를 이용하여 식생유형별 층위구조를 분석하였다. 그 결과 식생유형분류체계는 8개 종군유형과 5개의 식생단위로 구분되었다. 산림청 지정 특산식물은 9분류군, 희귀식물은 17분류군이 출현하였고, 북방계식물의 비율은 41.2%이며, 식생단위별 해발고도가 증가함에 따라 희귀-특산식물도 함께 증가하는 것으로 나타났다. 중요치 분석 결과, 구상나무는 모든 식생단위에서 평균상대우점치가 높게 나타났다. 또한 층위별로 보았을 때 식생단위 1을 제외한 단위들에서는 신갈나무, 당단풍나무 등의 수종과 경쟁관계에 놓여 있는 것으로 판단되었다. 본 연구의 결과는 기후변화로 인한 아고산대 산림식생의 변화를 이해하기 위한 기초 자료 뿐만 아니라 식생학적 접근을 통한 장기 모니터링의 기초지표로 활용될 것으로 판단되었다.

본 조사지역인 손죽도는 전라남도 여수시 삼산면 손죽리에 속하며, 지리적으로는 동경 127도 21분, 북위 34도 16분에 위치하고 있다. 유관속 식물을 대상으로 2001년 12월부터 2002년 11월까지 12개월에 걸쳐 식물상을 조사하였다. 본 연구결과 관속식물은 113과 291속, 519종, 60변종, 5품종 총 584종이 동정되었다. 이 지역은 전형적으로 곰솔이 우점종이며, 남방계 식물이 나타나는 특징을 가지고 있다. 이중 특산식물은 10과 10속 8종 5변종으로 총 13종류로 이 지역에서 관찰되는 전체식물종의 2.0%를 나타낸다. 회귀 및 멸종위기식물은 솔잎란, 애기등, 섬첨남성, 및 지네발란 등이 관찰되었다. 그 외에 귀화식물은 9과, 20속, 23종으로 우리나라 전체 귀화식물종 281종류의 8.2%로 조사되었다. 본 지역은 면적에 비해 한국특산식물, 회귀식물 및 멸종위기식물 등이 많이 분포하는 생태적으로 중요한 지역이지만 한편으로는 귀화식물의 점유율이 점점 높아지는 등 환경오염에 따른 인위적인 훼손의 위협 증대되고 있어 섬 전체에 대해 지속적인 정부의 강력한 관리 및 개발 규제가 있어야만 할 것으로 사료된다.

Veronica nakaiana Ohwi (Plantaginaceae) is an endemic taxon on Ulleungdo Island, Korea. We report the second complete chloroplast genome sequence of V. nakaiana. Its genome size is 152,319 bp in length, comprising a large single-copy of 83,195 bp, a small single-copy of 17,702 bp, and a pair of inverted repeat regions of 25,711 bp. The complete genome contains 115 genes, including 51 protein-coding genes, four rRNA genes, and 31 tRNA genes. When comparing the two chloroplast genomes of V. nakaiana, 11 variable sites are recognized: seven SNPs and four indels. Two substitutions in the coding regions are recognized: rpoC2 (synonymous substitution) and rpl22 (nonsynonymous substitution). In nine noncoding regions, one is in the tRNA gene (trnK-UUU), one is in the intron of atpF, and seven are in the intergenic spacers (trnH-GUG~psbA, trnK-UUU, rps16~trnQ-UUG, trnC-GCA~petN, psbZ~trnG-GCC, ycf3~trnS-GGA, ycf4~cemA, and psbB~psbT). The data provide the level of genetic variation in V. nakaiana. This result will be a useful resource to formulate conservation strategies for V. nakaiana, which is a rare endemic species in Korea.
