Floating reedbed launched in Wanstead Park to help improve water quality - Thames21

A floating reedbed has been launched on Heronry Pond in Wanstead Park, on the East London-side of Epping Forest, to create additional habitat for wildlife and help improve water quality.

The launch of the 160-square-metre floating reedbed is part of a £100,000 project to improve overall water quality in the 44,500-square-metre pond.

Environmental charity Thames21 is working closely with The Rivers Trust and the City of London Corporation, which manages Epping Forest as a registered charity, on the project. The project is funded by soft drinks manufacturer Britvic.

Although ponds and other blue spaces and lakes can be an oasis for wildlife and places for the public to enjoy, they can suffer from many environmental challenges, including road runoff pollution.

Road runoff occurs when pollutants settle on the surface of the road – such as residue from oil spills, as well as tyre and brake wear from vehicles. These build up during dry weather and are then washed into rivers and streams when it rains. ‘Natural barriers’ such as floating reedbeds can act as a sponge and can filter these pollutants before they flow into rivers.

Native species such as Purple Loosestrife, Yellow Flag Iris, and Common Reed, feature on the new floating reedbed. These species are a typical standard mix of wetland species that come in pre-established coir mats – materials which are crafted from coconut fibres and tightly packed together. They also help to enhance biodiversity by helping to support a range of wildlife, providing essential habitats and food sources.
