This study was carried out to investigate the ecological behaviour forage value and similarity among the plant communities of the grazing pasture near Witzenhausen in middle part of Germany. Sixteen plant communities of the different grazing pasture were mostly the Molinio-Arrhenatheretea and Festuco-Brometea, and those were named the class of plant sociological nomenclature. The ecological behaviour and forage value of the communities except mesobromion(half dry grassland community) were relatively good for forage production. The correlation coefficient between class No. 14 and 12 of plant communities was highest, and the similarity among the communities were greatly affected by botanical composition. The resemblance measure of the cluster-analysis by complete-linkage-method for the similarity among plant communities was better the euclidean distance than those of others. The clustering analysis showed that the communities of relatively similar botanical composition were closely grouped.

The plant community of water`s edge was investigated using the methodology of the Z-M school of phytosociology, from March to October, 2008, 2011. The results were obtained as follow ; hygrophyte hydrophye of 2008 year of this area consist of 38 taxa : 1 varieties, 37 species, 31 genera, 21 families and 14 orders, hygrophyte hydrophye of 2011 year of this area consist of hygrophyte 15 species, 13 species were reduced by approximately 13.33%. And emerged hydrophyres did not show a change. 9 species, 4 species of Floating-Leaved hydrophyres 55.56%, Submerged hydrophyres of the 4 species, 1 species, 75%, Free-Floating hydrophyres remarkable I the 3 species was reduced to 33.33%, respectively. Plants Community of the water's edge was classified into 16 communities as follows; (Leersia japonica community, Spirodela polyrhiza community, Miscanthus sacchariflorus community, Hydrocharis dubia community, Zizania latifolia community, Paspalum distichum var. indutum community, Leersia japonica-Hydrocharis dubia community, Salix glandulosa community, Trapa japonica community, Humulus japonicus community, Nelumbo nucifera community, Carex dimorpholepis community, Salix koreensis community, Trapa japonica-Spirodela polyrhiza community, Persicaria thunbergii). Higher in 2011 than in 2008, the ratio was reduced to Leersia japonica community. Between July-August by a sudden change in the rate of water storage changes in vegetation are thought to have appeared.

To investigate the flora of wetland at Mt. II-Kwang, the helophyte of the mountain was examined. The flora observed was classified into 2 phyla, 15 families, 27 genera, and 34 species. Representative species at the wetland were Drosera rotundifolia, Utricularia racemosa, Utricularia bifida, Eriocaulon miquelianum, and Eleocharis attenuata var. laeviseta. In the lower part of the wetland, water was abundant and soil surface layer was thin, and Eriocaulon miquelianum-Carex canescens-Drosera rotundifolia, community were developed. On the other hand, in the upper part of the wetland, water was not abundant and soil surface layer was thick, and Agrostis clavata-Phragmiles japonica community were community were developed. Utricularia bifida and Utricularia yakusimensis were growing abundantly at this wetland, but Utricularia racemasa was few in number and narrow in the distribution area. Eriocaulon miquelianum, a Korean endemic plant, was observed, and Habenaria linearifolia, Spiranthes amoena, and Epipactis thunbergii, the CITES plant, were observed at this wetland. Insectivorous plant such as Drosera rotundifolia, Utricularia racemosa, Utricularia bifida, and Utricularia yakusimensis were also observed.
