説明
We examined effect of vegetation management on the species composition in wetlands in a valley of hilly site (altitude 130-200 m) in Shiga Prefecture. The study site had been paddy fields until 20 years before the investigation was done. Two 1 x 1 m2 quadrats were mowed and other tow quadrats were tilled at eight stands of different types of vegetation. Cover of each species was recorded in these four quadrats and two control quadrats. Water level, water quality and light condition were recorded at each stands. Canonical Correspondence Analysis suggested that water level strongly affected on the species composition in the study site. The reed, Phragmites australis vegetation was formed in the stands with highest water level and Carex dispalata was formed in the site with lowest water level. Tilling and mowing also affect the species composition. These disturbances generally increased annual grasses and reduced perennial and tree species in general. However the magnitude and direction of the change were depend on the existing vegetation type.
