This study was carried out to investigate the vegetation of wetland and terrestrial lands in Jangdo wetland conserved area in Korea and to analyze the characteristics of the vegetation changes in the recent years. From the plant community, there were evergreen broad-leaved forests of the Machilus thunbergii, Castanopsis cuspidata, and Machilus thunbergii-Castanopsis cuspidata communities. Moreover, there were deciduous broad-leaved forests of the Salix koreensis, Mallotus japonicus, Mallotus japonicus-Pueraria thunbergiana and Celtis sinensis communities. Additionally, there were shrub forests of the Rosa multiflora-Rubus hirsutus, grassland of Molinia japonica-Miscanthus sacchariflorus and Miscanthus sacchariflorus-Imperata cylindrica communities, and plantation forest of the Pseudosasa japonica community. The area of the wetland vegetation (15%) was much narrower than that of the terrestrial land vegetation (85%). Comparing these results with those of the past 10 years, the wetland plant communities decreased by one-third and the proportion of neutral or dry plant communities increased. In order to mitigate landization succession of the wetland and maintain native wetland vegetation in this area, the expansion of the Salix koreensis community must be controlled to a suitable scale. In addition, it is urgently required to remove the invasive non-wetland plants, such as Pseudosasa japonica and Pueraria thunbergiana.

The use of land cover was sharply changed during 1975~2007 in the Kyungan watershed $(561.12 km^2)$. The changes occurred over an area of more than $227.65 km^2$ during the overall period at changing rates of 1.04% per year for water area, 1.79% per year for residential area, 2.99% per year for bare area, 3.03% per year for wetland area, 3.04% per year for grass area, 0.87% per year for forest and 2.32% per year for agriculture area. Water, residential, bare and wetland areas increased, while grass, forest and agriculture areas decreased during the last 32 years. BOD concentrations of representative sites for each sub-watershed continuously increased until the early 2000s as residential area increased with the highest discharged load, but decreased after the mid 2000s except upper Kyungan watershed. Such decline appears to be associated with the planning of Total Maximum Daily Load management for Gwangju city and expansion of waste water treatment plant. It is necessary to control land use/cover changes of the upper watershed and to prepare appropriate watershed management system for improvement in river environment including water quality, stream flow and bio-diversity.

Investigated was the ground-walking Coleoptera at the moor and adjacent forest at 800 m and rice paddies at lower level of 50 m in altitude. There were 5 species belonging to 5 genera and 2 families, 4 species belonging to 4 genera and 3 families, and 17 species belonging to 11 genera and 2 families respectively. Diplous depressus (Gebler) was the dominant species at the moor and forest in distinctive numbers, while Pheropsophus javanus (Dejean) was the one at the paddies. Three investigated sites supported independently their ground-walking Coleoptera groups. The moor group seemed to fail in establishing the resident Coleoptera community. The fact may imply to be related a kind of the pioneer species in early dry succession that D. depressus was found in a considerable range between forest and moor. The Coleoptera groups of moor and forest was different from that of paddies in species structure.

In this study, we report a new record of the clustered bur-reed Sparganium glomeratum (Laest. ex Beurl.) Beurl., from Yongneup Moor of Daeamsan Mt. in Gangwon-do, Korea. This species is distributed in the cool temperate and circumboreal regions of the Northern Hemisphere. As we recorded this species in a high-altitude wetland, we named it "Du-me-heuk-sam-neung" after the Korean word that translates to "Sparganium found in deep mountains." We provide descriptions of the morphological characteristics, photographs, and detailed illustrations of S. glomeratum, as well as a key to allied taxa in Korea.

Adenostemma madurense DC. (Asteraceae, Adenostemma L.), which is known to be distributed in Japan, Taiwan, Thailand and Nepal was recently found on Jeju Island in Korea. It is morphologically allied to A. madurense but distinguished from A. lavenia (L.) Kuntze by having such characters as broadly ovate or ovate to oblong leaves, $15-21cm\;long{\times}7-12cm$ wide and smooth achenes with slightly muricate at the upper. Furthermore, A. madurense is found in dry mountain slopes in evergreen forests while Adenostemma lavenia occures in the wetland and side of pond. This taxon was named 'San-mul-meo-wi' in Korean based on its habitat. We provide a description, illustrations, photographs, and the key to the related species in Korea.

This study was aimed to establish the method and process of the Biotope Mapping System.(B.M.S.) The main aspects of research for biotope were divided by 4 schemes such as biosphere, geosphere, antroposphere and evaluation informations. The cartographic function of GIS(geographic information system) was also used to mapping them. The B.M.S. had been progressed with 5 steps : (1) making research goals, (2) constructing the graphic and attribute databases, (3) classifying 3 types of biotope such as tree/shrub biotop, grass biotop and wetland biotop. (4) cross-analyzing biotope types against land use, habitat characters, relief characters and danger/disturbance elements, (5) evaluating the biotope's potentialities. Only 3 steps of them were done in this study. The results of applicating the B.M.S on the research site as followings : 1. The interdisciplinary researches were needed to develop the B.M.S in Korea since ecological habitat conditions of Germany, England are differed from them of Korea. 2. The distributions of the land uses in Maejuri, Seunghwan eup in Chonan city were mainly recorded by forest(29.82%), orchard(14.11%) and landscaping around building site(9.05%). 3. The percentages of the Tree/Shrub Biotope type were ranged by the orchard type(23.8%), natural and artificial deciduous type with natural coniferous(23.6%) and etc. 4. The Grass Biotope type was mainly recorded by the wild grassland type(27.99%), garden type(14.21%) and peddy field with wild grassland(13.24%). 5. The distributions of the wetland were pointed high at the wetland type with reed marsh and edge vegetation around wetland(54.79%) and etc.

This study was carried out to investigate soil properties, ordination, and vegetation of a forest wetland in Jangdo, Sinan-Gun. Peculiar species such as Epilobium pyrricholophum and Lycopus ramosissim us were found in the forest wetland of Jangdo, and Hosta yingeri and Carpinus turczaninovii for coreana that are an endemic species of Korea were also found. The vascular plants of 40 families 62 genera 57 species 9 varieties 1 form, total 67 taxa were accounted for. The communities were classified as Salix koreensis-Isachne globosa community, Isachne globosa community, and Miscathus sinensis var purpurascens community. Soil organic matter, total nitrogen, available phosphorous concentrations, and cation exchange capacity each ranged from 20.6 to 72.4%, 0.74 to 2.13%, 33.3 to 114.6 ppm, and 25.5 to 94.3 me/100g, respectively. Soil pH ranged from 5.10 to 5.42. Soil texture was clay loam. Results of the correlation between Jangdo forest community and environmental factor are as follows; Soil pH was the most effective factor for plant community distribution. The Salix koreensis-Isachne globosa community was found where it had the highest soil organic matter, nitrogen, and exchangeable Na, Ca, Mg concentration, ana CEC among the three communities. Miscathus sinensis var. purpurascens community was found where it had the lowest soil organic matter, nitrogen, and exchangeable Na, Ca, Mg concentration, and CEC among the three plant communities.

The Gonggeomji Reservoir is a historical irrigation facility built in the 8th century and designated as a wetland protected area by Ministry of Environment, Korea. In order to collect the baseline data necessary for developing a sustainable conservation strategy, we investigated the classification of actual vegetation, the vegetation distribution and the floristic structure of the vegetation in the Gonggeomji Wetland Protection Area. In the whole protection area, a total of 26 plant communities were classified including the wetland, riparian, grassland, forest, farmland, and orchard vegetation. According to the results of detrended correspondence analysis, the structure of wetland vegetation was mainly affected by water depth and human disturbance. In reservoir wetlands, floating vegetation such as Utricularia vulgaris var. japonica, Trapa japonica, and emergent vegetation such as Nelumbo nucifera, Typha spp. completely covered the water surface. Since 2014, the reservoir wetland has been terrestrialized with the expansion of emergent and hygrophytic plants. For the sustainable conservation and restoration of wetland protected areas, it is necessary to naturalize the topography and wetland vegetation, recovery the hydrologic system, and restore ecosystem connectivity from wetlands to forests.
