This study has investigated the growing features and vegetation of Acanthopanax chiisanensis and Acanthopanax koreanum in Mt. Jiri and Halla from Sep. 1997 to Aug. 1998. As to Acanthopanax chiisanensis, it occupied surrounding areas of Nogodan in Mt. Jiri of the height of 1,507m, ImgeolyoungJae of 1,300m and the Mt. Halla. of 1,100m of There were rather high constancy degree with Quercus mongolica, Schizandra chinensis, Hydrangen serrate for. acuminata, Acer pseudo-sieboldianum, Dryopteris crassirhizoma, Actaea asiatica, Thalictrum filamentosum, Abies koreana, Arundinella hirta from the sorts. The common species in Mt. Jiri and Halla are Acer pseudo-sieboldianum, Dryopteris crassirhizoma, Callicarpa japonica, Parthenocissus tricuspidata, Acer mono, Ligularia fischeri, Disporum smilacinum, Viola acuminata Aconitum kusnezofii. On the other hand, concerning of Acanthopanax koreanum community, it possessed the small areas of wedo weoltae village in Chejudo. In this area, a liana e.g. Dioscorea tenuipes, Hedera rhombea, Lygodium japonicum, Akebia quinata, Vitis thunbergii, Dunbaria villosa, Trachelospermum asiaticum var. intermedium, Vitis amurensis, Paederia scandens, lives with Pinux thunbergii, Celtis aurantiaca, Mallotus japonicus and so forth in tree layer and subtree layer. There is artificial change no move in the researching sites, Acanthopanax chiixanensis will be transformed into Abies koreana - Acanthopanax chiisanensis community. Soil characteristics showed the high value such as pH 6.56 and conductivity 0.258mmho/cm in Acanthopanax koreanum community of Mt. Jiri, they also indicated digit as follows: the content of organic matter and total nitrogen are from 25.16 through 25.35% and 7.58 through 9.30mg/g respectably. The soil characteristics at Acanthopanax chiisanensis community in Mt. Jiri and Halla, was high as like pH 5.76, conductivity 0.238mmho/cm, total nitrogen 9.30mg/g, total phosphorus 0.126mg/g in Mt. Halla.

The purpose of this study is to elucidate the characteristic of this study is of attitudinal variation of water quality for nine representative springs in the Halla mountain region. The evolutional processes of the spring water also have been studied. Results of hydrogeochemical analyses show that Gwaneumsa spring is very high in pH. The spring waters from Yungsil, Namguksunwon, Sungpanark Oremok and Gwaneumsa which springs situated lower than 1000m in altitude are relatively high concentrations in chloride, sulphate, nitrate nitrogen and sodium ions, indicating that they are affected by surrounding pollution sources. The concentrations of bicarbonate, sulphate and hydrogen ions in spring waters increase when the precipitation increases, whereas the concentrations of nitrate nitrogen, chloride and calcium ions decrease with increasing amounts of precipitation. The magnesium, sodium and electrical conductivity are nearly independent of the precipitation. The spring waters in the Halla mountain region belong to the groups of sodium or potassium type and bicarbonate type, except the Baegrogdam and Wiseorm spring water.

In order to improve a trip pattern in Mt. Halla climbing only to a summit, two trip programs with nature interpretation have been developed using the geomorphic characteristics of Mt. Halla which are distinct from those of mountains in the Korean peninsula. It also aims to help conservation of natural environment of Mt. Halla and to enhance the visitor satisfaction in Mt. Halla. The subalpine trip program is carried out on a 1.5 km-long trail between Wissaeoreum Hut and Janggumokoreum. Program participants are able to learn expertise about, and understand vulnerability of, a subalpine ecosystem, Consequently, the program can obtain an educational attainment getting them to recognize the necessity of preserving the subalpine zone of Mt. Halla as an important natural resource. The mountain river trip program is performed on a 1.5 km-long reach of Byeongmun River between Gwaneumsa trailhead and a gorge upstream of Gurin Cave. The program is capable of exhibiting effectively the river characteristics of Jeju Island using the geomorphic and hydrologic properties of Byeongmun River which differ from those of rivers in the Korean peninsula. Since the subalpine grassland and ephemeral stream of Mt. Halla are the visiting places which are rarely experienced in the Korean peninsula, the program participants can understand the regionality of Jeju Island as well as Mt. Halla through trip activities.

Korean fir (Abies koreana Wilson) is one of the most important environmental indicator tree species for assessing climate change impacts on coniferous forests in the Korean Peninsula. However, due to the nature of alpine and subalpine regions, it is difficult to conduct regular field surveys of Korean fir, which is mainly distributed in regions with altitudes greater than 1,000 m. Therefore, this study analyzed the vegetation change trend of Korean fir using regularly observed remote sensing data. Specifically, normalized difference vegetation index (NDVI) from Moderate Resolution Imaging Spectroradiometer (MODIS), land surface temperature (LST), and precipitation data from Global Precipitation Measurement (GPM) Integrated Multi-satellitE Retrievalsfor GPM from September 2003 to 2020 for Hallasan and Jirisan were used to analyze vegetation changes and their association with environmental variables. We identified a decrease in NDVI in 2020 compared to 2003 for both sites. Based on the NDVI difference maps, areas for healthy vegetation and high mortality of Korean fir were selected. Long-term NDVI time-series analysis demonstrated that both Hallasan and Jirisan had a decrease in NDVI at the high mortality areas (Hallasan: -0.46, Jirisan: -0.43). Furthermore, when analyzing the long-term fluctuations of Korean fir vegetation through the Hodrick-Prescott filter-applied NDVI, LST, and precipitation, the NDVI difference between the Korean fir healthy vegetation and high mortality sitesincreased with the increasing LST and decreasing precipitation in Hallasan. Thissuggests that the increase in LST and the decrease in precipitation contribute to the decline of Korean fir in Hallasan. In contrast, Jirisan confirmed a long-term trend of declining NDVI in the areas of Korean fir mortality but did not find a significant correlation between the changes in NDVI and environmental variables (LST and precipitation). Further analyses of environmental factors, such as soil moisture, insolation, and wind that have been identified to be related to Korean fir habitats in previous studies should be conducted. This study demonstrated the feasibility of using satellite data for long-term monitoring of Korean fir ecosystems and investigating their changes in conjunction with environmental conditions. Thisstudy provided the potential forsatellite-based monitoring to improve our understanding of the ecology of Korean fir.

To conduct ethnobotanical study that grow wild in biosphere reserves or are traded in nearby traditional markets, we collected and analyzed traditional knowledge information on vascular plants that live in Mt. Seorak and Mt. Halla. As a result, the ethnobotanical plants investigated in Mt. Seorak consisted of 102 families and 489 taxa. The ethnobotanical plants investigated in Mt. Halla consisted of 118 families and 374 taxa. Both ethnobotanical plants from Mt. Seorak and Mt. Halla were most widely used for oriental medicine and treatment, and leaves were the most used organ. Differences in diversity by family of ethnobotanical plants inhabiting Mt. Seorak and Mt. Halla showed significant differences only in other use. The ethnobotanical plants traded at the traditional market near Mt. Seorak consists of 59 species in 34 families and 56 genera. The ethnobotanical plants traded at the traditional market near Mt. Halla consists of 102 species in 49 families and 94 genera. All ethnobotanical plants traded in traditional markets were most often used for oriental medicine and treatment, and stems were used most often in the traditional market near Mt. Seorak, and leaves were used most often in the traditional market near Mt. Halla.
