Lee Navigation Volunteer Days: Floating pennywort removal

Thursday 12 June 9.30am - 2.00pm

Leaside Trust, Clapton

Three opportunities to help clear floating pennywort from the Lee Navigation.

  • 15 May, Leaside Trust Clapton
  • 17 May, Leaside Trust Clapton Open Day
  • 12 June, Lee Navigation

Floating Pennywort - Hydrocotyle ranunculoides

First naturalised in 1990 as a result of discarded plants from garden ponds. It spreads rapidly and can grow up to 20cm per day, quickly dominating a waterbody by forming thick mats and impeding water flow and amenity use. May out-compete native species by blocking out light, causing deoxygenation, obstructing air breathing insects and reducing water temperatures. It is found mostly in the south-east of England and occasionally in the northwest of England and Wales.

Here’s a couple of photos from one of our events, showing the flexible use of canoes in small creeks on the Lee where its harder for the bigger boats to access the Floating Pennyworts and working in collaboration with the canal boat and C&RT volunteers to help remove the plant mass
