  • We report on an unrecorded endophytic fungus, Grovesiella abieticola (Zeller & Goodd.) M. Morelet & Gremmen isolated from Abies koreana of Mt. Halla in Jeju. In this study, we used a culture method to determine its conidia and compared relative species using an internal transcribed spacer (ITS) 1, 2, and 5.8S ribosomal DNA sequence. Thus, we present the cultural characteristics and morphology of G. abieticola in this paper.

  • The present investigation was estimated the effect of temperature, precipitatiion, and time on the decomposition of litters with litter bags of Pinus densiffora and Quercus mongolica at Gure where elevation in 50m, and at Nogodan where elevation in 1300m on Mt. Jiri. As the above results, decomposition model was proposed to relation of the environmental conditions. And was investigated the production and decomposition of litters from the stands of various forest communities in Kwangneung, Mt. Jiri and Mt. Halla. The results are as follows; The models for the decay of organic carbon (C) was as follows: $C=Coe^{-Kt}$ (limiting factor;time) $C=Coe^{-K'te}$ (limiting factor;tempedrature) $C=Coe^{-KnP}$ (limiting factor:precipitation) As observed in litter bag method, the decomposition rate of litter in Pinus densiflora was slower than that of Quercus mongolica. The higher elevation, the slower decomposition rate. The decomposition of litters at Gure where elevation in 50m was equally influenced by temperature and precipitation. But at Nogodan where elevation in 1300m was much inflenced by precipitation. The decay constant of litters was larger in hardwood forest than in coniferous forest. In the same species, the more elevatiion, the less decomposition constant. The time required for the decay of 50%, 95^, 99% of the accumulated litters in the forest floor were faster in hardwood forest than in coniferous forest. In the same species, the higher elevatiion, the longer time required.

  • This study aims to compare and analyze the environment of natural parks and Ulleung island using the plant taxa classified by five degrees based on their distributional ranges. The scores differentially given based on the importance of each degree; taxa belonging to the fifth degree are given to 20 scores each, fourth 10, third 5, second 3.3, and first 2.5, respectively. The total assessed scores were ranked as Mt. Halla, Seorak, Jiri, Deokyu, Is. Ulleung, Mt. Sobaek, Odae, Palgong, Chink, Taebaek, Songni, Juwang, Gaya, Duryun, Gaeryong, Bukhan, Naebyeon, Worak, Naejang, Cheongryang, Naeyeon, Myeongii, Jokye, Mudeung, Wolchul, Geumo, Juheul, Biseul, Hwangmae, Jangan, Seonun, Moak, Seonam, Chilgap, and Gibaek, in order, respectively. It is suggested that the natural environments assessing more than 1,000 of total scores such as Mt. Halla and Mt. Deokyu are regarded as the most excellent ones, and those between 700 to 1,000 of total scores such as Is. Ulleung and Mt. Odae are regarded as relatively excellent ones. Natural parks scored between 500 to 700 such as Mt. Palgong and Mt. Gaya are regarded as good ones and parks scored between 300 to 500 such as Mt. Duryun and Mt. Mudeung are regarded as normal ones. The area assessed less than 300 of total scores such as Mt. Wolchul and Mt. Gibaek are regarded as the most inferior ones. The total scores of the national parks are generally higher than those of the provincial and county parks. In addition, Ulleung island has a total of 882.9 scores. Therefore, according to the IUCN the Ulleung island should be included in the criterion of the preservative model of natural ecosystem, suggested by Ministry of Environment. At the same time, Ulleung island should be included to the superior model of natural scenery resources by its uniqueness of topography, geography and natural environments. Ulleung island is assessed as having relatively excellent natural environments as compared with other national parks, suggesting that the island should be designated as a new national park.

  • This study was conducted to investigate differences in energy content of Quercus mongolica stands in the Republic of Korea with respect to latitude and altitude. Study sites were located in Mt. Joongwang, Pyeongchang-gun, Gangwon-do (altitude 1,300 m, 1,000 m, 800 m), Mt. Taehwa, Gwangju-gun, Gyeonggi-do (altitude 350 m), Mt. Wolak, Jecheon-si, Chungcheongbuk-do (altitude 300 m), Mt. Baekwoon, Gwangyang-gun, Jeollanam-do (altitude 800 m), and Mt. Halla, Jeju-do (altitude 1,000 m) by northern and southern aspect. Total energy content and annual energy fixation of Q. mongolica stands were 2,916-6,550 GJ/ha and 250-440 GJ/ha, respectively during the study period, Lower latitude (NE) stands of Q. mongolica showed more energy contents and annual energy fixation than higher latitude stands. Energy content and annual energy fixation of Q. mongolica stands were increased in low altitude. Energy content of Q. mongolica stands were higher in northern aspect than southern aspect. However, there were no significant differences in annual energy fixation between the aspects. Annual energy fixation of Q. mongolica stands was highly correlated with warm index and followed by descending orders: altitude, stand age, aspect, annual solar radiation and latitude.

  • Bangseonmun(訪仙門) is the attractive spots where Shinseon(神仙: Taoist hermit) ideas that makes Mt. Younju(瀛洲山) or the current Mt. Halla mystique has still remained and situated at Hancheon(漢川) Valley. Bangseonmun, which is known as 'Landscape Setting Here($L_{SH}$)' of Youngguchunhwa(瀛丘春花), which is one of ten famous spots in Youngjusipkyung(瀛洲十景), and Deulreonggui refer to 'the gate to the place where Shinseon is living.' It is described as the path to Mt. Youngju for Shinseon and the boundary between the mundane world and the world beyond the mundane. The old scholars at Mt. Halla entered the gate and met Shinseon, carving the word or picture of Bangseonmun, Whanseonmun, Wuseondae or Deungyounggu so as to structure the enchanting image on Bangseonmun. It is the poetic expression of the taste for the arts, breaking from the troublesome mundane world and riding the white deer to become the Shinseon, the desire for the ideal world in Taoism, and the identity of four famous scenic spots of Bangseonmun. Besides its enchanting meaning and the locational value of Bangseonmun, geological features of the valley and river and ecological value prove its unique value as a natural scenic beauty. Not to mention the locational identity and enchanting meaning of the poets carved in Meeaegak of Bangseonmun and the scenic view of 'Youngguchunhwa' as the subject of 10 famous scenes of Youngju, it is the place for communing with nature with the natural beauty of Bangseonmun Valley. As the cultural place for being together with Jeju people, it simultaneously shows the typical model as a scenic spot in our living. Viewing the scenic value and standard from the aspect of the Cultural Properties Protection Law, Bangseonmun Valley in Jeju must be the typical place and space that meet the requirements to become scenic sites.
