Mizorogaike Pond in Kyoto City is one of the most valuable wetlands in Japan in terms of the high biodiversity derived from the high moor in a floating island.  Because of its rarity and academic value, the “Biological Communities in Mizorogaike Pond'' has been designated as a National Natural Monument in Japan. Academic research conducted by Kyoto City between 1994 and 1996, however, revealed that non-native fish such as Largemouth Bass and Bluegill Sunfish were likely to have a significant impact on the “Biological Communities in Mizorogaike Pond”.  Therefore, in the spring of 1998, the “Mizorogaike Pond Aquatic Animal Study Group”, consisting of citizens and researchers, was established to investigate and control the non-native fish. Later, as the need for research and control of nonnative aquatic plants and reeds increased, it was decided to conduct vegetation management activities as well, and the name of the group was changed to the “Citizens Research Group on Aquatic Biota in Mizorogaike Pond” in 2001, together with the “Mizorogaike Pond Aquatic Plant Study Group” that was established in 2000.
