Salix were awarded the contract and began works to carry out 300 metres of riverbank protection to protect this existing exposed high pressure gas pipe in March 2013.

This was a design and build contract using large woody debris and willow revetments. The project dealt with severe riverbank erosion caused by the powerful tributary of the River Severn.

Salix coppiced 1500 live willow posts, sourced 45 whole trees and made 1000 live willow faggots from tree works in the same catchment as the works.
