Pennywort Alert is a collaborative project which empowers river users and local communities to understand, recognise, and report the non-native invasive species Floating Pennywort.

Currently focussing on the River Great Ouse from Bedford to Earith, and the River Witham from Lincoln to Boston, we are also looking for volunteer paddlers and anglers who wish to get more hands-on! Email for more information.
