This study was designed to predict the changes in species richness of plants under the climate change in South Korea. The target species were selected based on the Plants Adaptable to Climate Change in the Korean Peninsula. Altogether, 89 species including 23 native plants, 30 northern plants, and 36 southern plants. We used the Species Distribution Model to predict the potential habitat of individual species under the climate change. We applied ten single-model algorithms and the pre-evaluation weighted ensemble method. And then, species richness was derived from the results of individual species. Two representative concentration pathways (RCP 4.5 and RCP 8.5) were used to simulate the species richness of plants in 2050 and 2070. The current species richness was predicted to be high in the national parks located in the Baekdudaegan mountain range in Gangwon Province and islands of the South Sea. The future species richness was predicted to be lower in the national park and the Baekdudaegan mountain range in Gangwon Province and to be higher for southern coastal regions. The average value of the current species richness showed that the national park area was higher than the whole area of South Korea. However, predicted species richness were not the difference between the national park area and the whole area of South Korea. The difference between current and future species richness of plants could be the disappearance of a large number of native and northern plants from South Korea. The additional reason could be the expansion of potential habitat of southern plants under climate change. However, if species dispersal to a suitable habitat was not achieved, the species richness will be reduced drastically. The results were different depending on whether species were dispersed or not. This study will be useful for the conservation planning, establishment of the protected area, restoration of biological species and strategies for adaptation of climate change.

기후변화의 영향으로 자생지에서 고사하고 있는 구상나무 유묘의 대기온도와 연령에 따라 건전도를 파악하고자 지리산 구상나무 실생묘를 대상으로 엽록소형광을 측정하였다. 2020년 7, 8, 9월에 걸쳐 월별 1회씩 연생별(1, 2, 3, 5, 6년생) 20개체를 대상으로 13시, 19시에 개체당 3회 반복 측정하였다. 측정 당시 평균대기온도는 24.6, 26.9, 20.6℃이었으며 잎을 20분간 광을 차단 후 Fv/Fm값을 측정하였다. Fo는 식물이 암적응 된 상태에서 포화광을 조사하기 직전의 형광 초기값이며, Fm은 식물이 암적응 된 상태에서 포화광을 통해 유도된 최대 형광수치를 의미한다. Fv는 Fm-Fo이며, 광화학 반응의 최대 양자수율로 식물의 잎이 광합성을 수행할 수 있는 잠재력을 의미하고 식물의 광합성 활성과 건전도에 대한 지표로 사용된다. 일반적으로 건강한 잎의 Fv/Fm값이 0.8을 기준으로 낮은 값은 광계II의 반응 중심이 손상을 잎은 경우이거나 스트레스 환경에 있는 경우이다. 13시 측정 결과 8월 측정값 중 1년생과 3년생이 0.8 이하로 측정되었고 그 외에는 전부 0.8 보다 높게 나타났다. 19시 측정 결과 8월에 1, 2, 3년생이 0.8 이하로 측정되었으며, 9월에는 1년생의 경우를 제외하고 모두 0.8 보다 높게 나타났다. 1, 2, 3년생은 8월의 높은 온도에 영향을 받아 고산지대에 자생하는 구상나무의 특성상 고온에 대한 스트레스를 받은 것으로 판단되며, 연령이 비교적 높은 5, 6년생은 온도변화에 비교적 안정적인 것으로 나타났다. 따라서 엽록소형광 측정의 결과를 근거로 3년생 이하의 개체는 온도변화에 민감하게 반응하는 반면, 5년생 이상의 개체는 비교적 안정적으로 건전도가 유지된 것으로 판단되었다.

The object of this study was the climate change sensitivity assessment of Korean Fir and Khinghan Fir as a representative subalpine plant in South Korea. Using species distribution models, we predicted the probability of current and future species distribution. According to this study, potential distribution that have been predicted based on the threshold (MTSS) is, Khinghan Fir was higher loss rate than Korean Fir. And in the climate change sensitivity assessment using the scalar sensitivity weight ($W_{is}$), $W_{is}$ of Korean Fir was higher relatively than the sensitivity of Khinghan Fir. When using the species distribution models as shown in this study may vary depending on the probability of presence data and spatial variables. Therefore should be prior decision studies on the ecological environment of the study species. Based on this study, if it is domestic applicable climate change sensitivity assessment method is developed. it would be important decision-making to climate change and biological diversity of adaptation policy.

This study was conducted to prepare basic data by analyzing the biological values and environmental factors of algific talus slope in order to respond to climate change due to the greenhouse effect, and to establish plans for forest biodiversity preserving and managing. Meteorological information was measured and the flora of vascular plants were investigated for six algific talus slope by seasonally from 2020 to 2021. As a result of the investigation, the temperature of all 6 algific talus slope was lower than that of the area where the algific talus slope was located in summer, and flora was 101 families, 350 genera, 621 species, 18 subspecies, 57 variants, 7 varieties, 703 taxa. In sum, it is judged that the algific talus slope has sufficient reasons and value to be preserved because it has excellent micrometeorological value from the cold wind blowing in summer and phytogeographical value in which various plants live in a small area. However, in spite of such an important area, the management of algific talus slope is insufficient, and the algific talus slope is damaged or the ecosystem of the algific talus slope is disturbed. Therefore, it is necessary to establish a systematic conservation and management plan by designating algific talus slope as a forest genetic resource reserve and OECM.

The agricultural ecosystem is one of the major sources of greenhouse gas (GHG) emissions. In order to search for climate change adaptation options which mitigate GHG emissions while maintaining crop yield, it is advantageous to integrate multiple models at a high spatial resolution. The objective of this study was to develop a tool to support integrated assessment of climate change impact b y coupling the DSSAT model and the DNDC model. DNDC Regional Input File Tool(DRIFT) was developed to prepare input data for the regional mode of DNDC model using input data and output data of the DSSAT model. In a case study, GHG emissions under the climate change conditions were simulated using the input data prepared b y the DRIFT. The time to prepare the input data was increased b y increasing the number of grid points. Most of the process took a relatively short time, while it took most of the time to convert the daily flood depth data of the DSSAT model to the flood period of the DNDC model. Still, processing a large amount of data would require a long time, which could be reduced by parallelizing some calculation processes. Expanding the DRIFT to other models would help reduce the time required to prepare input data for the models.

The flora of the vascular plants in Deoksesan Mt. and its adjacent areas, located at Inje-gun, Gangwon province, were surveyed for a total ten times from April of 2018 to July of 2020. The result of this survey revealed 457 taxa, consisting of 90 families, 287 genera, 404 species, 13 subspecies, 35 varieties, and 5 forms. Among them, 12 taxa were endemic plants to Korea, and 7 taxa were rare plants. Red list plants and those designated as controlled Korean biological resources, requiring special permission for export outside of the county, numbered 3 and 103 taxa, respectively. The floristic target species amounted to 83 taxa, specifically 8 taxa of grade IV, 26 taxa of grade III, 21 taxa of grade II, and 28 taxa of grade I. In addition, 14 taxa were classified as plants adaptable to climate change, and 4 taxa at their respective northern limits, first recorded in this study, were also investigated. Twenty-nine taxa of alien plants and 4 taxa of ecosystem disturbance species were also found in this area. Our results suggest that some species should be preserved and can serve as basic information with which to establish data on the preservation of resources, such as plant diversity and distributional changes on Deoksesan Mt.

This study was conducted to investigate the vascular flora of two outstanding forest wetlands(OFW) in Goheung-gun, Jeollanam-do, and to prepare an efficient management plan for forest wetlands through comparison with previous studies. Fieldwork was conducted seasonally from May to October 2023, The flora in the two OFW located in Goheung-gun, Jeollanam-do, consisted of 117 taxa such as 55 families, 92 genera, 108 species, 7 variants, 1 variety and 1 hybrid. The endemic plants were 4 taxa and rare plants were 7 taxa. Floristic target plants were V class 2 taxa, IV class 6 taxa, III class 8 taxa, II class 4 taxa and Iclass 21 taxa. Climate change adaptation plants were 10 taxa and naturalized plants was 1 taxa. Obligate wetland plants were 16 taxa, Facultative wetland plants 10 taxa and Facultative plant 4 taxa. OFW functioning a typical wetland ecosystem in Goheung-gun had been providing habitats for a variety of rare plants, such as the Habenaria radiata and Drosera rotundifolia. But those ecosystems would be suffering a critical disturbance such as human interference, the invasion of naturalized plants, and change of wetland function through landization for a short future. Therefore we suggest those OFWs should be designated as a Forest Genetic Resource Reserve in order to keep the ecosystems permanently and to manage them more soundly and efficiently.
