The "Clean Campus Campaign - Elimination of Myriophyllum aquaticum (brasiliense) Part II" was carried out from Bangaike Pond, north of Gifu University main campus down to the stream that flows down within the campus on June 25, 2018. This campaign aims for conservation of biodiversity, and protection of river basin areas which is one of the goals of Gifu University's "Campus Master Plan."

Under the instructions of Associate Professor Takahiko Mukai of the Faculty of Regional Studies and Associate Professor Kengo Ito of the Faculty of Applied Biological Sciences, the students who volunteered, and the staff of the Facility & Environmental Affairs Department, worked together to eradicate the plant.

In the campaign in November 2017, Myriophyllum aquaticum (brasiliense), one of the designated alien species in Japan, was not totally eliminated, but thanks to the campaign, people can barely find the plant in and around the campus today. The participants also trimmed overgrown Nuphar japonica (waterweed) that was blocking the smooth flow of the stream. Nuphar japonica is the indigenous plant in Japan, but is not indigenous species found in Gifu University. It may pose a serious threat to the water flow if it overgrows, and may affect the ecosystem in the future. The students and the staff put on waterproof pants fitted with boots and went into the stream to trim Nuphar japonica.

Gifu University will continue its environment protection activities particularly focusing on indigenous breed from the viewpoint of biodiversity.
