Thames21 have installed a “floating ecosystem” in the Limehouse Cut, opposite their offices at Bow Locks. This 45- metre-long raft is planted with with native wetland vegetation, including reeds, on top. Below the raft, hanging brush-like structures provide habitat for juvenile fish, and also for microbes which improve water quality.
The floating ecosystem was installed with the help of volunteers in December 2015. The raft came in several pieces, and first had to be fixed together (see photo left). The project was funded by the Tower Hill Trust. Thames21 hope to install further, similar floating ecosystems in the Lee Navigation and other waterways in the borough.
