The purpose of this study is to offer the basic data for management of National Park by surveying and analysing the change of flora of damaged lands in Juwangsan National Park, Korea. In cause of occurring the damaged lands, site-1 was the vegetation damage by stamping, the removing Gwangamsa of site-2, 3, 4 and the removing Naewon village of site-5, 6, 7. Whole sites are caused by the artificial disturbance and interference. The numbers of flora were summarized as 135 taxa including 52 families, 109 genera, 116 species, 2 subspecies and 17 varieties in whole sites. The status of flora by sites, site-6 is the largest number of 52 taxa, site-1 is the lowest of 23 taxa. The rare plant is 1 taxa, 4 taxa of endemic plants, 10 taxa of specific plants by floristic region, 9 taxa of naturalized plants and 1 taxa of invasive alien plant. In the results of analysis about the change of coverage ratio, for this shrub layer, site-7 was changed to the most $0%{\rightarrow}50%$, and the herb layer, site-5 was changed to the most $75%{\rightarrow}95%$. In case of the change of species numbers, most sites tended to increase in the sites introduced different species or generated by the growth. It is contemplated that is similar to the restoration with the surrounding natural vegetation that is in progress is a transition occurs with the passage of time. In the dominant species, the shrub layer is Fraxinus sieboldiana, Lespedeza bicolor, Rhus javanica, Lespedezamaximowiczii, Salix koreensis and Zelkova serrata, and Miscanthus sinensis var. purpurascens, Oplismenus undulatifolius, Artemisia princeps, Bothriochloa ischaemum and Erigeron annuus of herb layer. In the results of analysing Naturalized Index(NI) and Urbanized Index(UI), NI was increased or decreased this phenomenon with the lapse of time, UI was the most increase. In particular, the increase in UI is due to the transition process, the pioneering plant, naturalized plant was imported to continue.

The pollen morphology of 31 taxa, representing all woody species from 12 genera of Fabaceae in Korea, was examined by light microscope and scanning electron microscope. The pollen grains were monad and prolate spheroidal or rarely subprolate in equatorial view. The pollen grain aperture was trizonocolporate or rarely trizonooperculate, which does not occur in the other families of Fabales in Korea. The exine showed a great variety of sculpture pattern, i.e. psilate, microperforate, densely microperforate, perforate, polygonal perforate, macroperforate, macroperforate with granules in holes, polygonal macroperforate, verrucate with pitted perforate striae, verrucate-perforate, granulate, rugulate, reticulate or refined reticulate. The pollen morphological data supported the idea that the genera Echinosophora and Sophora were congeneric. Caragana (Galegeae) was quite close to the Sophora group (Maackia, Sophora and Echinosophora) of the Sophoreae in each measured pollen parameter and exine sculpture pattern. Eleven genera of Fabaceae were recognized based on differences in aperture type, pollen grain shape and exine pattern, and a generic pollen key of the woody Fabaceae in Korea was developed. A key to pollen types of Lespedeza was also suggested. The examined taxa of Coronilla and Wisteria were recognized by their exine patterns.

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.

The study was to investigate and compare plants and frequency of appearing species of vegetation transect in a straight and a restoration Section of Bulgwang stream in Seoul. Some part of Bulgwang stream was restored as a closed-to-nature stream. This present study consists of two investigations, the first investigation being conducted on May and the second one on August -September 2003. Based on the analysis of the data collected from both investigations, this study classified and listed all of the plants appeared in a straight and a restoration section of the stream. The study used the Belt-transect method in order to examine and analyze discover the appearance frequency of the vegetaton transect per 200 meters. During the period of the first investigation and the second one, plants of 33 families, 73 classes, and 88 species appeared in the straight section, while plants of 36 families, 76 classes, and 90 species appeared in the restoration section. The Naturalized Index of the straight section was 22.7％, and that of the restoration section was 21.1％. As shown on the results indicating that the Urbanization Index of the straight section was 7.8％, and that of the restoration section was 7.4％, the Urbanization Index of the straight section was slightly higher than the restoration section. The results using belt-transect analysis method showed that in case of the straight section, the plants of the highest appearance frequency on the riverside were Persicaria hydropiper and Humulus japonicus. On the contrary, in the case of restoration section, the plants showing a higher appearance frequency on the riverside were identified as Salix gracilistyla, Persicaria hydropiper, Rumex crispus, and Humulus japonicus. In conclusion, there was no difference between the straight and the restoration section in the bank with regard to vegetation transect. However, a remarkable difference was found on the riverside for the Salix gracilistyla which was introduced in the restoration section.

The purpose of this study was to provide basic data for preserving forest ecosystem with understanding forest wetland condition of Mt. Cheongok. It was found from this research that vascular plants of surveyed area were composed of 72 families, 167 genera, 209 species, and 2 subspecies, 27 varieties, 5 formae. totaling 243 taxa. Among the investigated vascular plants, Korea endemic plants were 9 species, rare plants 15 species, and naturalized plants 8 species, respectively. According to the occurrence frequency within the wetland investigated, obligate upland plants (OBU) accounted for 75.72% (184) among the total species investigated, wherea obligate wetland plant (OBW) were four species (4.65%). There were 26 of hygrophyte plants and 2 of emergent plants in the research area according to wet degree. According to habitat category, the most frequently occurred habitat was forest (136 species, 55.97%), and the others were in the order of meadow and shrubland (70 species, 28.81%), wet meadow (35 species, 14.40%), and aquatic environment (2 species, 0.82%), respectively. In the result of analysis of important value, Fraxinus rhynchophylla and Carex pseudosinensis was the highest as 22.17% and 10.40%. It was confirmed that the species diversity was relatively high. Shannon-Wiener's species diversity index was calculated as 2.507. Based on these results, long-term monitoring survey should be urgently needed for ecological restoration and recovery.
