The purpose of this study was to understand phytosociological characteristics and changes, providing basic ecology informations based for heronries. We investigated the 25 heronries sites to have more than a hundred nests in the country. The vegetations of heronries were arranged 8 plant communities that consisted of 60 families, 129 genuses and 167 species including 17 species of exotic species. The communities of heronries were composed of high NCD (Net Contribution Degree) of plants, such as pokeberry (Phytolacca americana), japanese chaff flower (Achyranthes japonica), asiatic dayflower (Commelina communis) including diagnosis species, that was heliophilous and tolerance of eutrophic and/or acidic soil condition, and had the highest composition with the annual plants. As locational condition, they were distributed a favorite feeding place (rice field, stream etc.) inside 0.5 km radius, and located on the eastern slope of the mountain. The vegetative composition among plants in the heronries didn’t have plant sociological characteristics for environmental conditions of the sites. But generally, they had trends in floristic composition like the areas of polluted soil, open canopy and disturbance.

Damyang riverine wetland was designated as a wetland protected area in 2004; that is located in the Yeongsan river mainstream. Total 30 phytosociological releves at field studies were classified with 22 vegetation types including of 101 species (unidentified 1 species). Legends of actual vegetation map were separated by 6 types; riparian forest, substitute vegetation, synanthropic vegetation, wet meadow vegetation, open water, an area of wetland vegetation is about 35 % (386,841.86㎡). Results of this study area as follows. The plant society of Damyang riverine wetland was conjectured that it was formed by rapidly water environment change with installed weir on the upstream of protected area and operating of Damyang dam on top of the basin. Until recently, the terrace land on the river was used to cultivate, but that would be formed fallow vegetation scenery on riverfront caused by no cultivation after designated protected area. Paspalum distichum var. indutum community designated as invasive alien plant by Korea Ministry of Environment was widely developed and Myriophyllum spicatum unrecorded in the country as newly alien species was discovered in the study zone. The plants as lapped over developing environment for Leersia japonica must be occupied habitat of native plant species having similar niche. The various plant society in Damyang riverine wetland should be developed because of environmental changes, disturbances and damages of stream.
