Gwangdeoksan Mountain (699.3 m) is the highest border mountain between the two cities of Chungcheongnamdo Province, Cheonan and Asan, Korea. In this study, we investigated the flora of Gwangdeoksan Mt. from April of 2015 to October of 2017. Through 20 independent field investigations, we identified and tallied a total of 428 species, 9 subspecies, 30 varieties, and a forma in 287 genera and 97 families. Of a total of 468 taxa, 128 taxa in 112 genera and 58 families were found to be Korean endemic species (7 taxa), floristic regional indicator species (45 taxa), rare or endangered species (3 taxa), species subject to the approval of outbound transfer (73 taxa), and alien or ecosystem disturbing species (32 taxa). The flora of Gwangdeoksan Mt. can be divided into four distinct floristic subregions, with higher diversity in the north-facing subregion. The complex flora of Gwangdeoksan Mt., emerging at the edge of two floristic regions of the Korean peninsula, may represent a significant conservation priority and a topic for future ecological and geographical studies.

The purpose of this study is to offer the basic data and method for assessing the naturaliness of temple environment by applying the ecological index of plant to quantitatively and objectively assess the flora and to understand the flora distributed in major temple forest. The ecological index of plant was based in the surveyed flora. The whole flora were summarized as 535 taxa including 103 families, 310 genera, 426 species, 5 subspecies, 82 varieties and 22 forms. And, the numbers of taxa in the Beopheungsa were 267 taxa, 314 taxa of the Daeseungsa and 296 taxa of the Seongjusa. The rare plants were 9 taxa including Aristolochia contorta, Viola albida, Arisaema heterophyllumand so forth, and the Korean endemic plants were 11 taxa including Clematis trichotoma, Stewartia pseudocamellia, Vicia chosenensis and so forth. The specific plants by floristic region were 51 taxa including Wistaria floribunda, Celtis aurantiaca, Angelica gigas and so forth, and the pteridophyta were 26 taxa including Osmunda japonica, Polystichum braunii, Onoclea orientalis and so forth. The naturalized plants were 35 taxa including Fallopia dumetorum, Conyza canadensis, Xanthium strumarium and so forth, the invasive alien plants were 3 taxa including Ambrosia artemisiifolia, Aster pilosus and Eupatorium rugosum. In the results of analysing the ecological index of plant in whole temple forests, RI(Rare Index) was 1.7%, 2.1% of EI(Endemic Index), 9.5% of SI(Specific Index), 1.2 of PI(Pteridophyta Index) and 6.5% of NI(Naturalized Index) in narrow sense. In broad sense, FI(Flora Index) was 11.0%, 1.5% of RI, 3.4% of EI, 4.8% of SI, 10.1% of PI, 10.9% of UI(Urbanized Index) and 25.0% of DI(Disturbed Index). The FI of the Daeseungsa was the highest among the three temple forests. In narrow sense, the RI, SI, NI and DI of the Beopheungsa was high, the seongjusa was higher the EI and SI. In broad sense, the RI and SI of the Beopheungsa, the EI, SI and PI of the Seongjusa, the UI is high in the Daeseungsa. In future, if we will analyze ecological index of plant in other temple forests, we will offer the help to establishing the plan of conservation and restoration on ecosystem in whole temple forests.Environmental Specimen Banks (ESBs) are playing pivotal role in monitoring the effect of environmental pollution on the ecosystem based on the retrospective analysis of the representative samples collected regularly and stored in cryogenic condition.

오존 등 기체상 오염물질의 식물 표면에 대한 건성침적은 식물의 생물학적 활동에 피해를 줄 수 있으며(Runeckles and Chevone, 1992; Chappelka and Chevone, 1992), 건성침적 현상은 노출된 식물지표 환경의 화학적 특성을 변화시키는 작용으로 관심의 대상이 되고있다(Businger, 1986; Galbally et al., 1986; Chang et al., 1987; Wesely, 1989; Hicks et al., 1989). 이러한 기체상 오염물질의 침적현상은 대기질 관리에 있어서 오염물질의 적절한 감소계획을 산정ㆍ평가하기 위하여 지상 오염물질의 농도를 정확하게 추정하는 과정에서 필수적으로 고려되어야 하는 부분이다.

25만 여종에 달하는 지구상의 식물은 생물권의 무수한 환경변화 속에서 종을 유지할 수 있도록 다양한 유전적인 진화를 통하여 지구상에 정착하였다. 이들 식물이 생육하고 있는 기상환경은 매우 다양하며, 생장과정에서 수많은 환경변화를 시간적ㆍ공간적으로 경험하게 된다. 생육 환경이 변화하면 식물의 형능적, 생리적, 생합성적 특성이 변화하는 반응이 나타난다. (중략)

The wetland in the city could be mainly divided into the deep water type and the abandoned paddy type, so this study was conducted to analyze characteristics between the two types of the wetland. The former sample site was located near the Olympic village in Songpa-gu of Seoul, and the latter sample site was in front of the Mt. Bukhan fortress in Eunpyeong-gu of Seoul. The actual vegetation, vascular plants, and avian fauna were researched. In the actual vegetation, the deep water type had the broad surface of water and the emerged plant as Phragmites communis have grown widely, but the abandoned paddy type had the narrow sur-face of water and hydrophyte as Persicaria thunbergii have grown widely. It might be judged because the water depth of the abandoned paddy type were shallow wholly. And the floating-leaved plants and the free-floating planktonic plants were not observed such as Nymphaea tetragona var. angusta, Lemna paucicostata in the abandoned paddy type wetland. The wild birds were mainly observed at the edge of the wetland(at the edge of woodland) in the abandoned paddy type, but were observed equally in the deep water type. 28 families 433 species were observed at the former site and 32 families 365 species were observed at latter site. It was judged that the various topographical structure(habitat diversity) might make all items various.

The purpose of this study was to collect the basic data on establishing the conservation plan for the domestic wetland through flora and life form analysis at Junam wetland. The vascular plants were recorded as 222 taxa; 58 families, 167 genera, 200 species, 3 subspecies, 1 forma and 18 varieties. Among 8 life forms, Therophytes (Th), Hemicryptophytes (H) and Hydrophytes (HH) showed high percentage, and these species comprised 71.1% of the whole flora at Junam wetland. One taxa (Euryale ferox) rare plants designated by Korea Forest Service were observed. The naturalized plants were 38 taxa including Fallopia dumetora, Oenothera odorata, Ambrosia artemisiifolia var. elatior and so forth, and naturalized ratio was 17.1%. The naturalized made up about 45 percent of the species composition. The specific plants by floristic region were 13 taxa including Euryale ferox., Hydrocharis dubia, Prunus davidiana and so forth.
