The character and differential species of Abies koreana community, a subalpine coniferous forest, on Mt. Hall a and its vegetation unit were reviewed, based on literature published up to date. Song and Nakanish (1985a) originally described Saso-Abietetum koreanae Song et Nakanishi 1985 for the community. At that time, we were fully justified in establishing the nomenclature. Nevertheless, against this nomenclature, Yim and Kim (1990) made a objection, and it was renamed as what is called Saso quelpaertensi-Abietetum koreanae (Song et Nakanishi) corr. Yim et Kim 1990. In their previous study(Yim et al., 1990) being the root of the nomenclature, however, they did not study on the full layers containing the moss layer of bryophyte and lichen for the stratification of the Abies koreana community, in spite of the importance of the species of moss layer for the selection of character and differential species of vegetation units belonging to Vaccinio-Piceetea Br.-Bl. 1939, and also the floristic composition from their study was not compared with that of the vegetation units of the subalpine coniferous forests in Korea Peninsula, Japan, Maritime Province of Siberia and Northeast China. Among the four character species selected by them, it is clear that Maianthemum bifolim and Lonicera maackii are species no having the characteristic value from the phytosociological viewpoint. Besides, Sasa quelpaerthensis described in their nomenclature is a synonym of S. palmata (Suzuki, 1978). Therefore, their nomenclature is invalid and comes under a contravention (Infringement of Priority) to the Code of Phytosociological Nomenclature (Barkman et al., 1986). Saso-Abietetum koreanae was amply justified also by author's recent study (Song, 1991)examined throughout the range of subalpine coniferous forest in Korea. With the discussion of justification of Saso-Abietetum koreanae, a association discussion was brought in the present review.

The purpose of this study is to present the raw data for management and conservation of tidal flat by objective surveying and analysing the halophytes and vegetation distributed in Seocheon tidal flat wetland conservation area, Korea. The results are as follows. The numbers of halophytes in this site were summarized as 27 taxa including 13 families, 21 genera, 26 species and 1 variety. In the results of ecologically important species, rare plant was 1 taxa, 10 taxa of the specific plants by floristic region, 1 taxa of naturalized plant and 1 taxa of the plant with approval for delivering oversea. The life form spectrum consisted of therophytes(44.4%), hemicryptophytes(25.9%), geophytes(14.8%), nanophanerophytes(7.5%), chamaephytes and hydatophytes(each 3.7%). The types of vegetation of Seocheon tidal flat wetland conservation area were classified with 17 communities including Vitex rotundifolia community, Suaeda maritima community, Calystegia soldanella community and so forth. In the halophytes composition, section C and E-1 had the largest character species and companion species. In the results of vegetation amount, section C, D, E-1 and E-2 were the highest score, on the other hand, section A and B were the lowest. The final rating was calculated by adding up values of two factors, and section C and E-1 had the highest rating of II. In future, we will survey the whole flora in Seocheon tidal flat, we will offer the help to establishing the conservation plan of coastal plant ecosystem in West Sea.

Tropical forests have variety of biodiversity values, which provide invaluable services to the living being on earth. In the recent years, tropical forests are regarded as valuable global resources that act as sink for carbon dioxide in order to mitigate global climatic change. In many parts of the world, tropical forests are being rapidly cleared by various means. Soil organic carbon (SOC) is concentrated in the upper 12 inches of the soil. So it is readily depleted owing to the degradation activities. In the present study, it was aimed to assess the magnitude of disturbance in the availability of SOC in a semi- evergreen forest, situated in the Eastern Ghats of Tamil Nadu, India. The forest density of this region was mapped with QuickBird satellite data. Intensive field soil sampling and floristic study were conducted to estimate the SOC status in different density classes and to identify the species availability. The SOC density ranged from 274.06 t/ha to 147.84 t/ha in the very dense and degraded semi-evergreen forest respectively. The SOC content was also varied from 3.70 to 1.83 % in the very dense semi-evergreen and medium semi-evergreen forests respectively. The species composition in different density classes was also varied considerably. As a result of this study, it was identified that the disturbance to forests by various means not only affect the density of forests but also affect the below ground SOC status proportionately.

This study was carried out to investigate the developmental process of plant community during the secondary succession and changes of soil properties in the burned areas lapsed 28 years after the forest fire in Mt.Palgong. The forest fire occurred on March, 1969 and the red pine (pinus densiflora) forest and its floor vegetation were burned down. The results are summarized as follows: the floristic composition of burned and unburned areas were composed of 49 and 48 species of vascular plants, respectively. The dominant species based on SDR4 of the burned sites were Lespedeza maximowicxii(87.75), Carex humilis (62.94), Rhododendron schippenbachii(55.78) and Miscanthus sinensis var.purpurascens (51.94). In contrast, Pinus densiflora (81.17), Quercus serrata (53.58)m Carex humilis (53.11) and Miscanthus sinenis var. purpuracens (52.42) were dominant in the unburned area. The biological spectra showed the $H-D_1-R_5-e$ type in both areas. The indices of similarity (CCs) between the two areas were 0.80. Degree of succession (DS) was 734 in the burned area and 809 in the unburned area. The species diversity (H) and evenness indices (e) in the burned and unburned areas were 2.05, 2.13 and 0.53, 0.55, respectively. Dominance index (C) in the burned and unburned areas were 0.30 and 0.32, respectively. Soil properties such as soil pH, content of organic matter, total nitrogen, total carbon, exchangeable potassium, sodium, calcium, and magnesium in burned area were comparatively higher than those of unburned area. Monthly changes of soil properties were of little significance except for some cases. These results suggest that there was relationship between trend of vegetation recovery and the changes of soil properties after the forest fire. Mixed forestation of fire-resistant species and nitrogen fixation species will be effective for reforestation after the forest fire.

In order to analyze the succession process from a pine forest to an oak forest, the tree growth of Pinus densiflora and Quercus mongolica ssp. crispula was monitored in a permanent quadrat for 23 years. The measurements were carried out for the stem diameter (DBH) of Pinus densiflora between 1977 and 1999 and for the height of Quercus mongolica ssp. crispula saplings between 1998 and 2000. The floristic composition and the locations of the individual P. densiflora and Q. mongolica ssp. crispula trees and saplings in the quadrat were recorded. P densiflora and Q. mongolica ssp. crispula individuals were randomly distributed within the quadrat. The relative growth rates (RGR) of DBH in P. densiflora were 0.085 $yr^{-1}$ for large trees and 0.056 $yr^{-1}$ for small trees in 1977. The RGR of height for Q. mongolica ssp. crispula was 0.122 $yr^{-1}$. The growth curve for DBH of P. densiflora was approximated by the logistic equation: $$DBH(t) = 30 {[1+1.16exp(-0.13 t)]}^{-1}$$ where DBH (t) the DBH (cm) in year t and t is the number of years since 1977. The growth in height of P. densiflora and Q. mongolica ssp. crispula was described by following equations: $$H (t) = 20.2 {[1+0.407exp(-0.137 t)]}^{-1} (P. densiflora)$$ $$H (t) = 30 {[1+20.7exp(-0.122 t)}^{-1} (Q. mongolica ssp. crispula)$$ Where H (t) is the tree height (m) in year t and t is the number of years since 1977 in P. densiflora and 1998 in Q. mongolica ssp. crispula. With these equations we predicted that the height of Q. mongolica ssp. crispula increases from 2 m in 1999 to 20 m in 2029. Therefore, Q. mongolica ssp. crispula and P. densiflora will be approximately the same height in 2029. The years required for succession from a pine forest to an oak forest are expected 33 with the range between 23 and 44 years.
