Responses of riparian vegetation to flooding disturbance in a sand stream
This study compared vegetation map, transect, vegetation structure, and plant morphology before and after flooding in the Strea m Cheongmi, a sand stream, in order to investigate responses of riparian vegetation against flooding disturbance. Landform around channel was remarkably changed due to flooding disturbance in the sand stream. Erosion and deposition particularly provided new habitats to some riparian plants such asPhragmites japonica andRorippa islandica. As flow discharge increased due to flooding,Persicaria thunbergii community also increased in low landform adjacent to stream water.Miscanthus sacchariflorus with strong stem survived flooding disturbance.Humulus japonicus invaded abovePhragmites japonica community fallen by flooding disturbance. Major riparian vegetations in the Stream Cheongmi were quickly restored and sustained after flooding disturbance, giving little changes in community structure. Among annual and biennial plants,Persicaria nodosa adapted to flooding by forming aerenchyma in its stem internode, andRorippa islandica finished its life cycle before flooding.Phragmites japonica, Artemisia selengensis, andPhalaris arundinacea among perennial plants were restored by resprouting new shoots from stem node or rhizome of fallen or buried shoots by flooding disturbance.Miscanthus sacchariflorus resisted against flooding standing rather than being fallen. In conclusion, riparian vegetations in the Stream Cheongmi sustained their particular structures by getting adapted to repeated annual flooding disturbance.
