  • Imports of genetically modified (GM) soybeans (Glycine max) for food or feed consumption in Korea have been increasing. Although the cultivation of GM soybeans has not yet been allowed in Korea, the number of field tests for GM soybeans has also been rising. This study was conducted to investigate whether herbicide tolerant GM soybean can survive and persist in uncultivated environments when they escape from transportation routes or from isolated fields. Seeds of GM and non-GM soybeans and wild soybeans (Glycine soja) were buried in 2 and 15 cm soil depths and their viability was examined after 1, 2, 6, and 10 months. GM and non-GM soybean seeds completely lost their viability within six months of burial, whereas seeds of wild soybean maintained their viability during the study period. Seeds of soybean and wild soybeans that were sown on the soil surface germinated and grew to vegetative cotyledon stage. Seedlings of GM and non-GM soybean did not compete well with weeds, including Cerastium glomeratum, Alopecurus aequalis var. amurensis, Capsella bursa-pastoris, Conyza canadensis, Stellaria aquatica, and Erigeron annuus. Also, GM soybean did not survive through winter. However, wild soybeans competed well with the weeds and became dominant in August. Herbicide tolerant GM soybean is unlikely to persist under uncultivated environments and to become weeds.

  • This study investigated in the vascular plants of special protection zones (the native land of Berchemia berchemiaefolia in Sadam-ri and Gallon valley) of Songnisan National Park and identified the whole vascular plants. The numbers of vascular plants were summarized as 273 taxa including 82 families, 182 genera, 236 species, 3 subspecies, 28 varieties and 6 forms. Woody plants were identified as 124 taxa (45.4%) and herbaceous plants as 149 taxa (54.6%). A total of 107 taxa were identified in the area of Sadam-ri, and 246 taxa were found in the Gallon valley. A total of 8 taxa of rare plants were identified, each of which was divided into 1 taxa of endangered (EN; Daphne pseudomezereum var. koreana), 3 taxa of vulnerable (VU; Paeonia japonica, Berchemia berchemiaefolia and Iris minutiaurea), 3 taxa of least concern (LC; Aristolochia contorta, Syringa patula var. kamibayshii and Goodyera schlechtendaliana) and 1 taxa of data deficient (DD; Alangium platanifolium). The Korean endemic plants were 9 taxa (Clematis trichotoma, Thalictrum actaefolium var. brevistylum, Aster koraiensis, Cirsium setidens, etc.). In the specific plants by floristic region were 34 taxa, a degree I were 17 taxa (Chloranthus japonicus, Celastrus stephanotifolius, etc.), 9 taxa of a degree II (Euonymus pauciflorus, Acer triflorum, etc.), 4 taxa of a degree III (Aconitum longecassidatum, Angelica gigas, etc.), 2 taxa of a degree IV (Ulmus macrocarpa and Daphne pseudomezereum var. koreana), 2 taxa of a degree V (Berchemia berchemiaefolia and Alangium platanifolium). The naturalized plants were 5 taxa including Fallopia dumetorum, Trifolium repens, Ailanthus altissima, Oenothera biennis, Erigeron annuus. Naturalization rate (NR) was 1.8% of all 273 taxa of vascular plants and the invasive alien plants were not found. The purpose of this study is to identify the flora that grows in the special protection zones of Songnisan National Park and provide the basic data for the management of the special protection zone in the future.

  • This study observes the purchased lands in riparian areas of Suncheon City region and proposes a reasonable management method. For the study, the site surveying and analysis on the neglected purchased lands is executed, then, based on the site analysis result, the appropriate management method for each neglected purchased land is established. Each management method is approached from the ecological restoration perspective. According to site surveying and analysis of the neglected purchased lands, most of the sites were bare and agricultural lands. The reason for this is thought to be as when purchasing a land, the areas with higher nonpoint source pollution are bought preferentially. As for the dominant species coverage, 26% ($364,000m^2$) of the total neglected purchased land area in Sucheon City was covered with the dominated species, and for the exotic species coverage, 17% ($232,000m^2$) of the total neglected purchased land area in Sucheon City was covered with the exotic species. The survey site constituted of five different invasive species such as Japanese Hop (Humulus japonicus), Daisy Fleabane (Erigeron annuus), and Evening Primrose (Oenothera odorata). As for the natural succession on site, about 47% of the area showed poor natural succession process. The reason for this outcome is understood as having a lack of appropriate management for purchased lands. Based on the site surveying and analysis, especially the current management state of the and its location, the research site was categorized into preservation, restoration, and improvement sites. During the establishment of the ecological riparian belt, the comprehensive management for preservation, restoration, and improvement of the purchased lands should be executed.

  • This study examines the characteristics of the herbaceous vegetation structure of Haneul Park District in World Cup Park, which had previously been used as a landfill for 15 years. The survey was carried out through actual vegetation and vegetation structures from 2003 to 2006, biannually. Firstly, as a result of analysis of actual vegetation, the autumn season changed more quickly over the 2 year span than did the spring season in terms of actual vegetation area. Annual plants increased for the initial $3{\sim}4$ years and then perennial plants increased. Secondly, the results of analysis in vegetation structure are as follows: 1. The number of planted species gradually decreased. 2. Miscanthus sinensis var. purpurascens of the control region was maintained but Imperata cylindrica var. koenigii of the non-control region was invaded by Miscanthus sacchariflorus, Glycine soja and Phragmites communis etc. 3. Planted species in the control region were maintained in superior state, but the non-control region was changed by natural occurrence plants until 2006, the fourth year. 4. Physostegia virginiana and Aster koraiensis which were planted in the non-control region were maintained but most of planted species weakened and changed by natural occurrence plants including Erigeron annuus, Artemisia princeps, Setaria faberii and Phragmites communis etc. Based on the results, we suggested the management method of herbaceous vegetation in the Haneul Park District.

  • This study was carried out to select proper species for early stage replantation in granite forest road cut-slope. From one to thirteen year elapsed forest roads in five regional areas of Chungcheong-do and Kyungsangbuk-do, sample plots were selected, and their vegetations and environmental factors were investigated. Soil organic matter, total nitrogen, soil moisture content, and bulk density in the granite weathering soils were below 0.5%, 0.02%, 10%, and above 1.2g/$cm^3$, respectively. The environmental factors affecting distribution of species in the granite forest road were the elapsed year, elevation, cut-slope aspect, and cut-slope. Sowing plants of Dactylis glomerata, Lolium perenne, and Eragrostis curvula were found in the early stage of forest road-cut. Annual herbs of Youngia denticulata, Erigeron annuus, etc. were found in the 2-3 years elasped forest road-cut. Perennial herbs of Artemisia princeps var. orientalis, Miscanthus sinensis, etc., parachute woody plants of Weigela subsessilis, Pinus densiflora, etc., and gravitative trees of Prunus sargentii, Lindera obtusiloba, Quercus sp., etc. were found in the forest road cut-slope after 3 years of road-cut. Leguma of Lespedeza cureata, Amorpha fruticosa, Lespedeza bicolor, Pueraria thunbergiana, Albizzia julibrissin, etc., herbs of Artemisia keiskeana, Artemisia princeps var. orientalis, Miscanthus sinensis, etc., and woody plants of Rubus crataegifolius, Weigela subsessilis, Zanthoxylum schinifolium, Pinus densiflora, etc. were considered as proper species for replantation in granite forest road cut-slope.
