Salix were involved in the construction of in-channel features to help restore the River Quaggy in Lewisham.
The River Quaggy is classified as a chalk stream. However, urbanisation has significantly degraded the watercourse within London.
The confluence between the River Quaggy and the River Ravensbourne was historically culverted, but recent development has led to the deculverting of the watercourses and the confluence.
Since installation, vegetation has established well to provide excellent habitat. The area provides a vital refuge for wildlife as the watercourse is culverted both upstream and downstream.
