We analyzed the vegetation environment at the stream section of habitat in which Cottus koreanus lives. The plant communities were classified into Fraxinus rhynchophylla community, Acer ginnala-Salix koreensis community, Phragmites japonica-Salix gracilistyla community, Salix gracilistyla community, Phragmites japonica community, Robinia pseudo-acacia community, and Oenanthe javanica-Persicaria thunbergii community. The frequency of Phragmites japonica-Salix gracilistyla community was the most. And also the frequencies of Fraxinus rhynchophylla community and Salix gracilistyla community were high. In stream bank zone and terrace zone, the typically represented vegetation was the Fraxinus rhynchophylla community and Acer ginnala-Salix koreensis community and Phragmites japonica-Salix gracilistyla community, respectively. The rNCD of the top-priority plants applied to restoration of the vegetation in stream bank zone came out by the order of Ulmus davidiana var. japonica, Salix koreensis, Acer ginnala, Salix gracilistyla, and Fraxinus rhynchophylla. The rNCD in terrace zone was arranged by the order of Salix gracilistyla, Phragmites japonica, and Artemisia princeps. The spatial distribution of vegetation was the most greatly influenced by cross-sectional position of the surveyed stream, and this aspect is believed to be due to the habitat's physical stability. Species diversity also obviously makes a great difference depending on their surrounding physical stability. |
