ABSTRACT

This study was carried out to understand the spatial distribution and conservation, restoration plan for vegetation in the Hwaeom wetland protected area. Total 29 phytosociological releves consisted of 117 plant species (unidentified species contained) was made during field studies conducted at 2008 and 2013 applying Braun-Branquet method. The collected vegetations were arranged 8 plant communities and thus divided hydric types (Drosera rotundifolia-Eleocharis congesta community, Carex forficula-Molinia japonica community) and xeric types (Miscanthus sinensis community, Rhododendron yedoense var. poukhanense community, Tripterygium regelii community, Carex gifuensis-Quercus mongolica community) under moisture conditions. The hydric types growing in hydric conditions distributed along hollowed out ground or the water channel that have a key qualification to protect. In the wetland protected area, the hydric vegetation types were mostly covered about 3.8% and the xeric types dominating by Miscanthus sinensis were most wildly distributed about 51.5%. Various woody plant species invaded the place. In 2008, invasion plants observed with total 14 species - 8 tree species (227 individual), 6 shrub species (51 individual) and alders (Aluns japonica) found in 2013. We suggested finding out that the sustainable conservation and management in Hwaeom wetland should be setting up plan focused on activity and variability such as continuous monitoring (changing vegetation types, spatial distribution, invasion plants) and zonation management (core zone, buffer zone, transition zone).
