Description

We investigated the influences of lower ground water level on the hygrophytic weed which luxuriated at the abandoned paddy field as a pasture establishment method in wetland with consideration to wildlife habitat. In comparison with the control, the leaf of common reed (Phragmites communis Trin.) at the drainage area was decreased by the 60% in weight and distributed at lower layers due to water stress. The photosynthetic rate of the common reed was also decreased by 64%. At the end of the growing season, the botanical composition began to include more short type species.
