Pond plants, such as Floating Pennywort (Hydrocotyle ranunculoides) can spread extremely quickly dominating water courses.

In this video, produced as part of the Be Plant Wise campaign, Dave Ottewell and Alice Chapman of the Environment Agency and Bill Lawrenson of Canoe England discuss the invasion of this plant on the River Tame at Tamworth.
