地下水位の調節による湿原植生の保全と復元

抄録

Hokkaido is known for the landscapes of its wetlands, which occupy more than 60% of all wetlands in Japan. One of these, Sarobetsu Mire, in northern Hokkaido, have valuable high moors, animals, birds and rare plants in these area. However, in recent years, Sarobetsu mire has been facing the problem of drying caused by development and changes in its hydrological cycle. And more, drying process has allowed to invade the dwarf bamboo.

This study examines an effect of restraint of dwarf bamboo activity by control of groundwater level and possibility of restoration of marshland vegetation by chipping off the dwarf bamboo in the groundwater level controlling area at study area.
