  • The aim of this study was to determine the current distribution area of Robinia pseudoacacia habitat and to estimate its stand yield as well as its carbon stocks. In order to do so, the area of R. pseudoacacia distribution is obtained based on the large-scaled forest type map (1:5,000). Also, Weibull diameter distribution model is used to predict the yield of R. pseudoacacia stands. In addition, carbon emission factor is applied to calculate carbon stocks and removals. To obtain the stand yield of R. pseudoacacia, we developed estimation equation considering growth factors of the stand, e.g. mean diameter, the basal area, maximum and minimun diameter and etc. and tested it to ensure accuracy. Consequently, estimation equation derived from all growth factors have shown significance that could also be used for analysis. Site index was also established to determine the productivity of the forestland that later turned out to be ranging from 16 to 22. Based on these results, stand yield tables were drawn up. R. pseudoacacia is widely distributed in inland areas of Gyeongsang, Chungcheong and Gyeonggi provinces which covers total area of 26,770 ha. And when it is converted into carbon stocks, it amounts to 2,517,598tC with annual carbon uptake of 3.76tC/ha which is comparable to Querqus species that is known to storer large amounts of carbon. Therefore, R. pseudoacacia is also expected to serve as a viable carbon pool that would contribute to the mitigation of climate change. Furthermore, stand yield tables, an outcome of this survey would assist not only in proper management but also in sustainable management policy of R. pseudoacacia.

  • Forest vegetation of Hwangjangsan (1,077.3 m) in Woraksan National Park is classified into mountain forest vegetation. Mountain forest vegetation is subdivided into deciduous broad-leaved forest, mountain valley forest, coniferous forest, riparian forest, afforestation and other vegetation. Including 55 communities of mountain forest vegetation and 4 communities of other vegetation, the total of 59 communities were researched; mountain forest vegetation classified by physiognomy classification are 28 communities deciduous broad-leaved forest, 12 communities of mountain valley forest, 3 communities of coniferous forests, 2 communities of riparian forest, 10 afforestation and 4 other vegetation. As for the distribution rate for surveyed main communities, Quercus mongolica and Quercus variabilis communities account for 65.928 percent of deciduous broad leaved forest, Fraxinus rhynchophylla - Quercus mongolica community takes up 41.459 percent of mountain valley forest, Pinus densiflora community holds 86.100 percent of mountain coniferous forest holds. In conclusion, minority species consisting of Quercus mongolica, Pinus densiflora, Quercus variabilis, Fraxinus rhynchophylla, and Quercus serrata are distributed as dominant species of the uppermost part in a forest vegetation region in Woraksan National Park. In addition, because of vegetation succession and climate factors, numerous colonies formed by the two species are expected to be replaced by Quercus mongolica, Quercus variabilis, and Fraxinus rhynchophylla which are climax species in the area.

  • This study was established to provide basic information necessary for ecological management to restore the naturalness of black locust (Robinia pseudoacacia L.) plantations located in the mountains of Gyeongbuk, Korea. Using vegetation data collected from 200 black locust stands, vegetation types were classified using the TWINSPAN method, the spatial arrangement status according to the environmental gradient was identified through DCA analysis, and a synoptic table of communities was prepared based on the diagnostic species determined by determining community fidelity (Φ) for each vegetation type. The vegetation types were classified into seven types, namely, Quercus mongolica-Polygonatum odoratum var. pluriflorum type, Castanea crenata-Smilax china type, Clematis apiifolia-Lonicera japonica type, Rosa multiflora-Artemisia indica type, Quercus variabilis-Lindera glauca type, Ulmus parvifolia-Celtis sinensis type, and Prunus padus-Celastrus flagellaris type. These types usually reflected differences in complex factors such as altitude, moisture regime, successional stage, and disturbance regime. The mean relative importance value of the constituent species was highest for black locust(39.7), but oaks such as Quercus variabilis, Q. serrata, Q. mongolica, Q. acutissima, and Q. aliena were also identified as important constituent species with high relative importance values, indicating their potential for successional trends. In addition, the total percent cover of constituent species by vegetation type, life form composition, species diversity index, and indicator species were compared.

  • This study was carried out to investigate the flora and vegetation in wetland of Mueuido. The forest vegetation was classified into 2 communities group (Utricularia bifida-Eriocaulon sikokianum and Alnus japonica) and 6 communities (Rhynchospora chinensis, Phragmites communis, Molinia japonica, Ischaemum crassipes, Quercus serrata and Pinus rigida-Miscanthus sinesis). Resources vascular plants were composed of 30 families, 53 genera, 50 species and 8 varieties, totaling 58 taxa. Among the investigated resources plants, Utricularia bifida and Utricularia racemosa were rare and endangered species. The special plants based on floral region by Ministry of Environment were 5 taxa; V rank species 2 taxa, II rank species 1 taxa and I rank species 2 taxa. A naturalized plants was 1 species of totaling 290 species appeared in South Korea. The Life-form were Hydatophytes (20.7%), Geophyte (19%), Microphanerophytes (19%), Hemicryptophytes (17.2%), Nanophanerophytes (17.2%), Chamaephytes (5.2%), Therophytes (1.7%). In marsh-type wetland of Mueuido, we predict that bog-type swamp, where various type of swamp plants are distributed, is starting to be formed based on the fact that Utricularia bifida and Utricularia racemosa, insectivorous plants, are dominant and sphagnum also is found. Along with the notion, there are reportedly found serious damages around wetland by human being and we have to prepare protection plans against it.

  • The objectives of this study were to classify the types of vegetation in Pinus densiflora for. erecta stands. The study sites were located at Sokwang-Ri, Mt. Chungok(1,276m), Uljin, Mt. Kumma(1,017m) and Mt. Eungbong(1,267m). Two hundred thirty releves were classified and explained by phytosociological analysis(the method of ZM schools), and the results were summarized as follows. Pinus densiflora for. erecta stands were classified into Vaccinium koreanum community, Rhododendron micranthum community, Quercus dentata community, Acer pseudosieboldianum community, and Typical community. Quercus dentata community was divided into Festuca ovina group, Robinia pseudoacacia group, and Typical group, and Acer pseudosieboldianum community was divided into Hydrangea serrata for. acuminata group, Disporum smilacinum group, Magnolia sieboldii group, Carpinus laxiflora group, and Typical group, and Typical community was divided into Melampyrum roseum group and Typical group. And some groups were divided into 7 subgroups. Therefore, Pinus densiflora for. erecta stands had total of 16 vegetation units, out of those units, Vaccinium koreanum community distributed all over the studied areas. While Rhododendron micranthum community distributed mainly at Sokwang-Ri and Mt. Chungok. Therefore it was considered to be useful indicator in determining the range of afforestation and natural distribution of Pius densiflora for. erecta stands. The classified vegetation units were investigated by using of coincidence method. The results indicated that Quercus dentata community distributed mainly below 100 meters at the sea level, while other communities distributed above 350 meters at the sea level. According to the correlations between vegetation units and topography, Vaccinium koreanum and Rhododendron micranthum communities distributed mainly above middle slope areas, Quercus dentata community distributed mainly from lower slope to upper slope areas, Acer pseudosieboldianum community distributed mainly between valley and lower slope areas, and Typical community distributed mainly above upper slope areas. According to the correlations between vegetation units and 5 study areas, Quercus dentata community was distributed in the region of Uljin, and other communities were evenly distributed over other studied areas. According to the correlations between the units and aspects, all communities occurred all aspects, but most of the communities tended to be more distributed at south slopes than at north slopes, which meant that the relic stands of Pinus densiflora for. erecta were remained largely as patch phase status at south slopes.
