Invasive Species

In common with other Norfolk and Suffolk catchments, the Waveney has many invasive non-native species.

The Trust goes out weekly to manage the spread of the invasive aquatic species, floating pennywort. The above video shows our Rivers Project Officer out with volunteers at the end of June 2022. Control work parties are carried out every Friday in the upper Waveney from the bank and from canoes. If you are interested in helping out you can contact Katie Utting, Rivers Project Officer on 07810 214831 katie@riverwaveneytrust.org

The Trust has been part of efforts to eradicate American mink. The mink predates on water vole and has caused a devastating reduction in this valued native species. Waterlife Recovery East, is an ambitious project to eliminate mink from East Anglia.

River Waveney Trust volunteers regularly tackle invasive Himalayan balsam on the river banks - balsam bashing is really effective if carried out on successive years and we have had great success at some sites with keeping this invasive species under control.
