Last summer Purple-fringed Riccia moss was found massively in the Overijssel canal, east of Zwolle. Purple-fringed Riccia is a moss species floating on the water which occurs mainly in the Dutch big rivers and in the fen regions. From the surrounding area, the species was not previously known. Purple-fringed Riccia is an indicator of clean water.

The discoverer of the species, Melchior van Tweel, found the Purple-fringed Riccia (Ricciocarpos natans) during a cycling holiday in Lemelerveld village along the Overijssel canal.
