Abstract
In The Lake Biwa Comprehensive Development Project, in order to prevent the area by the lake from flood damage, we had constructed the levees with a road for management, internal drainage facilitied, and so on.
Though these facilities are indespensable to protect precious lives and property of the residents by the lake, on the other hand, construction of these facilities inevitably destroy a part of reed communities.
Therefore, besides these flood control projects, we decided to plant reed in the lake shore near the levees and seemed to be suitable for growing of reed. So, we made the preliminary experiment of planting reed from 1982 to 1986, and carried out the work of planting reed from 1987 to 1991.
As a result, the planted reed communities are not inferior to the natural reed communites in growth and the planted reedbeds fulfill the same function for the birds as the natural reedbeds do. The total area of planted reed communities is about 5ha.
