Lindera sericea, which belongs to genus Lindera in the Lauraceae family, is labeled under Least Concerned (LC) among Korean rare plants, floristics specific species IV grade and also flagpole species of the Mudeung National Park. It is distributed in Mt. Mudeung, Mt. Cheonbong and Mt. Chogye within gradients from $12^{\circ}$ to $51^{\circ}$. The slope area is from northeast to northwest sides and the altitude range of distribution site is between 220 m and 533 m. The vascular plants in the quadrate where Lindera sericea were studied were identified as a total of 72 taxa; 37 families, 54 genera, 66 species, 5 variants and 1 forma. Among the floristics specific species, IV grade species was Lindera sericea and III grade species were Stewartia pseudocamellia and Acer palmatum. Korean endemic species were Stewartia pseudocamellia and Carex okamotoi. As for the vegetation group, Quercus mongolica and Q. serratak - Lindera sericea, Styrax japonicus populations were found in Mt. Mudeung area where Lindera sericea appeared, Stewartia pseudocamellia-Lindera sericea and Sasa borealis populations were found in Mt. Cheonbong areas, Carpinus laxiflora - Lindera sericea and Sasa borealis populations were found in Mt. Chogye area, and Stewartia pseudocamellia-Lindera sericea and Sasa borealis populations were found in Songgwangsa area. A total number of 662 Lindera sericea individuals were examined. The number of trees with 1 trunk including younger individuals was 353 (53.32%), and the number of trees with 2 to 5 stems was 270 (40.79%). The number of trees with the greatest number of sprouts was 27. Of 662 trees in total, the total number of sprouts was 1,198. Among these, 699 trees (58.34%) were between 50 cm and 150 cm in height. The tallest tree was 585 cm. The most common root-collar diameter of sprouts (992, 82.81%) was under 1 cm, followed by the sprouts with collar diameter from 1.0 to 1.5 cm(156, 13.2%). Among them, the largest root-collar diameter was 3.2 cm. This Lindera sericea specimen had the tallest trunk (565 cm) which was torn lengthwise on one side. Its root and breast parts were decayed by 50% and 25 respectively. Some branches of the three trunks that were more than 4 m in length were dead in the apical portion. Therefore, it is proposed that the Korean Lindera sericea maintains an apical dominance tree type while showing morphological adaptation as a typical shrub because it autonomously decays some branches and trunks over a certain height while increasing the number of its sprouts.

The vegetation of Mt. Joghesan of a provincial park in Cheolanamdo was surveyed over twenty times from July, 1980 to December, 1981. The plants of Mt. Jonghesan consisted of 10 forma, 107 varieties, 597 species, 424 genera and 122 families, and among them were 204 species of esculent plants, 199 species of medicina plants and 30 species of the others oil plants and fiber plants. Evergreen herbs consisted of 12 species, including Coniogramme intermedia, Asplenium sarelii, and Asplenium incisum etc. And Evergreen broad-leaved trees consisted of 22 species, including Thea sinensis, Sasa borealis, and Quercus acuta etc. And evergreen needle-leaved trees consisted of 15 species, including Torreya nacitora, Pinus densiflora, Sciadopitys japonica, and Chamaecyparis obtusa etc. The community of broad-leaved consisted of Quercus spp, Carpinus laxiflora, Sasa borealis, including leading dominant species of Lespedeza maximowiczii, Viburnum erosum, Fraxius rhynchophylla, Viburnum dilatum, Rhus trichocarpa, Zelkova serrata, Miscanthus sinensis, Eragrostis ferrugina, Carex augustinowiczii persicaria filiforme var. neofiliforme, Vicia amoena, Smilax riparia var. ussuriensis, and Aster yomena etc. The vegetation of Seunamsa areas in Mt. Joghesan was favorable but the vegetations of the other areas in the mountain were negligible. The vegetation of Koolmokchi areas which had been much destroyed by forest fires was mostly covered with Quercus spp which are resistant to forest fires. Lindera sericea, Alangium platanifolium var. macrophyllum, Ilex macropoda, Corylopsis coreana, Albizzia julibrssin of old trees, Acer mono, the community of Thea sinensis, Stewartca koreana, Cornus alba, Dryopteris bisstiana, Asplenium incisum, Camptosorus, Lepisorus thunbergianus, gastrodia elata, Cymbidium goeringii, and the community of Persicaria filiforme var. neofiliforme etc. in Mt. Jonhesan are autochthonous flora, and their preservation is required. As the Pinus densiflora forest in Mt. Joghesan which was hewn down by human power has not been restored, Jeopchi areas and Koolmokchi areas in Mt. Joghesan have no Pinnus densiflora trees 700m above the sea level.

This study was conducted to investigate the vegetation structure of Zone 2 of Mudeungsan National Park Old Trail. A total of 60 survey plots were installed to survey the forest structure, and TWINSPAN and DCA analysis classified them into 5 communities. The community I was classified into Deciduous broad-leaf tree, II into Pinus densiflora-Quercus serrata, III into Quercus serrata, IV into Lindera erythrocarpa, and V into Quercus mongolica. The grouped communities showed some differences in species compositions according to elevation. In the four communities except for community IV, Styrax japonicus and Sasa borealis formed a dominant population in understory layers and in shrub layers, respectively, and the current community forms are expected to be maintained. Monitoring of vegetation succession of lower vegetation after temporary flowering and withering in the ridges developed in the shrub layers in communities II through IV is required. In the long-term aspect, the competition between the pine tree and oak tree communities requires observation of a decrease in the power of the pine tree community. Mudeungsan National Park's Old Trail ecologically valuable as it has a vegetation structure that is distinctively classified according to altitude and is a habitat of Lindera sericea, the flagship species of Mudeungsan National Park. It means that the excellent forest ecosystem of Old Trail must be conserved through sustainable utilization.
