Regeneration process of the Korean beech (Fagus multinervis Nakai) forest was studied in relation to the distributional pattern and age structure. In this study, it was clarified that the Korean beech forest is regenerated in both way: seedlings(sexual reproduction) and sprouts(vegetative reproduction) formations. In the large gaps, seedling may be established, resulting in clusters of even-aged individuals. But in the small-sized gaps, there may filed by the extention of surrounding trees and/or by the young trunks, which have sprouted from the base of stumps. As most gaps in the F. multinervis forest were derived from falling of a single stem, regeneration by sprouts seems to be more common than that by the seedlings.

This study was carried out to investigate the micromorphology of vessel wall sculpture such as shape of perforation plate, perforation rim, steepness of perforation plate, occurrence of vestured pit, warty layer and ray-vessel pitting on 13 species of Fagaceae in Korea. The results were summarized as follows ; 1. In the species examined, all sample species except Fagus crenata var. multinervis have simple perforation plate. But Fagus crenata var. multinervis has simple and scalariform perforation plate (it was called to combination perforation plate) in a tree stem. 2. The shapes of perforation rim could be classified into five types; Type A without tail, Type B with small tail on both sides, Type C with long tail on both sides, Type D with tail only one side and Type E with the very short interval between perforations. Among five types, Type Band C have higer frequency of distribution than the others. 3. The steepness of perforation plate measured was about 20 degree on pore zone and 43 degree on outside parts of pore zone. 4. Species with vestured pit were Q. aliena, Q, dentata, Q. variabilis, Fagus crenata var. multinervis, Castanopsis cuspidata var sieboldii, Q. acuta, Q. stenophylla, and Q. glauca. But the extent of vesturing was very slight and vestured pits were observed mainly in ray-vessel pit of some vessel elements. 5. Species with warty layer on the inner surface wall of all vessel elements were Q. acuta, Q. stenophylla, Q. glauca, Fagus crenata var. multinervis and species with warty layer of some vessel elements were Q. aliena, Q, dentata, Q. variabilis, Castanopsis cuspidata var. sieboldii. 6. Species with palisade ray-vessel pit were Q. acuta, Q. stenophylla, Q. glauca, Castanea crenata, Castanea bungeana, Q. aliena, Q. serrata, Q. mongolica, and species with scalariform ray-vessel pit was Fagus crenata var. multinervis and species with oval ray-vessel pit were Q, dentata, Castanopsis cuspidata var sieboldii.

Ten plots were established to study the vegetation structure of the Songinbong virgin forest in Ullungdo. It was classified into three communities Fagus crenata var. multinervis commnunity, Acer okamotoanum-Fagus crenata var. multinervis community, and Acer okamotoanum community. Shannon's diversity indicies of this area were not high(0.5150~0.8437), due to the geographical and vegetational characteristics. Considering the community structure(importance value, distribution of DBH class, and so on), the vegetation of the Songinbong virgin forest are thought to be stable continuously. With the analysis of plant growth type, it was presumed that Acer okamotoanum have increased after artificial disturbances in this area where Fagus crenata var. multinervis had been dominanat.

To determine the effects of underlayer vegetation on soil properties, the profiles, physical, and chemical properties of soil were investigated upon Fagus multinervis -Rumohra standishii, Fagus multinervis - typical, and Fagus multinervis -Sasa kurilensis subcommunities that was growing at Songinbong area of Ullungdo. There were little differences in soil profile properties among the three subcommunities. Also, there were little differences in physical and chemical properties of soil among the three subcommunities, except exchangeable Ca concentration in 0-10 cm soil depth. However, the soils of the study area in 0-10 cm soil depth comprised high organic matter and total N concentration as in an average value of 21.6% and 0.74%, respectively. Also, the soil showed very low bulk density and pH as in an average value of 0.43 g/㎤ and 4.4 in 0-10 cm soil depth, respectively. Due to the high soil organic matter and total N concentrations and the low bulk density and pH, the soil properties of Songinbong area are different from those of other forest in Korea.

To elucidate the origin and patterns of establishment of insular plants on Ulleungdo Island, maternally inherited chloroplast DNA, which is useful for tracing seed movements, was used. Fagus multinervis, an endemic species that dominated broadleaf deciduous forests on Ulleungdo Island, is an excellent model for such a study. To understand the diversity and spatial distribution of the chloroplast haplotypes of F. multinervis, nucleotide sequences of the psbA-trnH region were determined from 144 individuals sampled throughout the island. Results of a phylogenetic analysis of the region with close relatives of F. multinervis suggest that F. multinervis is sister to a clade of F. japonica and F. engleriana. No haplotype variation was found within F. multinervis. This remarkably low cpDNA haplotype diversity is in contrast to the findings of previous allozyme studies of F. multinervis populations that showed high genetic diversity on Ulleungdo Island. Repeated colonization during the early stage of establishment via birds that migrated from a source area where the F. multinervis cpDNA haplotype was geographically structured may have resulted in the observed pattern of haplotype diversity. Alternatively, long-distance dispersal of seeds of the progenitor of F. multinervis via birds or typhoons to Ulleungdo may have been a single event, whereas the immigration of pollen from the mainland likely occurred frequently. Comparative phylogeographic studies of other species endemic to Ulleungdo Island and their close relatives on the neighboring mainland are necessary for a more complete understanding of the evolution of the island's native species.

The montane forests of Ulreung Island, Korea, were investigated by the ZM school method. By comparing the montane forests of this island with those of Korean Peninsula and of Japan, a new order, F a g e t a l i a m u l t i n e r v i s, a new alliance, F a l g i o n m u l t i n e r v i s, a new association, H e p a t i c o-F a g e t u m m u l t i n e r v i s and Rhododendron brachycarpum-Pinus parviflora community were recognized. The H e p a t i c o - F a g e t u m m u l t i n e r v i s was further subdivided into four subassociations; Subass. of Sasa kurilensis, Subass. of Rumohra standishii, Subass. of Rhododendron brachycarpum and Subass. of typicum. Each community was described in terms of floristic, structural and environmental features.

The purposes of this study were to classify community and to analyzse vegetation-environment relationships in the forest community of Ulleung Island. The forest community of Ulleung Island was classified into Pinus thunbergii community, Pinus densiflora community, Neolitsea sericea community, Pinus parviflora community, and Fagus multinervis - Sorbus commixta community. Since the results of phytosociological community classification were consistent with that of TWINSPAN, it proved that these two methods could complement when one does a community classification. There was a difference in chemical characteristic of soil among study communities. The community had high soil organic matter, total nitrogen, available phosphorous, and cation exchange capacity compared to forest soil of Korea. The soil pH ranged from 4.66 to 5.80. The soil texture in the study communities was loam or sandy loam. According to the ordination analysis, elevation, exchangeable Na, K, Ca, Mg, soil pH, and content of sand and silt affect the distribution of community.

The forest vegetation of the Korean Peninsula is dominated by deciduous Fagaceae forests. The study aimed to comparethe correlation between species composition and environmental factors in Namsan, Odaesan, and Ulleungdo. A vegetation survey of 75 sites was conducted from May to August 2018. Seven vegetation types were classified. The inland representative vegetation was classified as a Quercus mongolica community, and the island representative vegetation was classified as a Fagus multinervis community. The Quercus mongolica community was subdivided into the Aria alnifolia group, representative of cities, and the Tilia amurensis group, representative of mountainous regions. Analysis of important values and indicator species to examine the succession trends according to regional types showed that urban and island forestswere maintained as Fagaceae communities, and that mountainous region foreststransitioned to broadleaf species, such as Tilia amurensis and Carpinus cordata. A CCA analysis of vegetation type and site environmental factors showed that altitude had the biggest effect on species composition at the same latitude. The study results should contribute to a better understanding of the Korean Peninsula forest ecosystem characteristics and provide basic data for establishing a systematic conservation and restoration plan.

The virgin forests on and around Sungin-bong in Ulreung-do, an island situated between the Korean peninsula and Japanese archipelago, were investigated phytosociologically. They were classified into two communities, i.e. Fagus crenata var. multinervis - Majanthemum dilatatum community and F. crenata var. multinervis - Sasa kuriensis community. The former was subdivided into several units ; Acer takesimense - Allium victorialis var. platyphyllum group, including Tsuga sieboldii - Taxus cuspidata var. tatifolia subgroup and a typical subgroup, and Acer mono var. savatieri - Rumohra standishii group, including Dystaenia takeshimana subgroup and a typical subgroup. The other was subdivided into two subunits ; Acer okamotoanum group and a typical group. It was estimated that this area was orginally covered with beech and maple dominated forest vegetation and with Machilus dominated forest or bamboo forest. However, in these days, The natural vegetation of it has been destroyed and in future, may also be disturbed gradually by human activities. Judging from the coincidence method, the structure and distribution of the forest communities was more related to altitude than to topography. The phytomass, based upon the basal area of each community to $100m^2$ showed that Acer mono var. savatieri - Rumohra standishii group ($BA=7574.1cm^2$, $P=9,882,058cm^3$) haved the largest value and Tsuga sieboldii - Taxus cuspidata var. latifolia subgroup($BA=2126.3cm^2$, $P=1,746,755cm^3$) showed the smallest value. The flora of the vascular plants collected from this area consists of 71 families, 187 genera, 243 species, 1 subspecies, 44 varieties, 6 forms and 294 taxa in total.
