Site description (2007 baseline)
Katano-Kamoike was once a valley formed by fall of the sea level, the uplift of the land and erosion by running water. It was subsequently filled with water to form a pond. The area is covered with various aquatic plants. Around the pond there spread scrub forests such as Quercus crispula, broadleaf forests. Since the Edo Era, rice has been grown in paddy fields from spring to summer. Thanks to this fact the environment of wetlands has been preserved up to the present. But, due to the rice acreage reduction policy and the aging of farmers, rice cultivation is decreasing. As a result, Phragmites australis and other aquatic plants have grown thick and are gradually filling in the pond with their sediment (through the process of eutrophication).
