	\|Project summary=During the creation of a bypass by the river, the burn was engineered by encasing it in gabion baskets to provide structural protection for the roadway piers. Reno mattresses were also used to prevent down-cutting by the burn. In the high-energy environment of the burn, the reno mattresses' protective PVC layer was eroded and the galvanised coating of the mattresses exposed, causing them to split open and the withheld material released. The remaining wire became a hazard for fish, snaring many. Additionally, the downstream gabions would often block surface water in low-flow conditions, with water simply flowing 'through' them in the gaps in between. Accordingly, fish migration was often blocked.		\|Project summary=During the creation of a bypass by the river, the burn was engineered by encasing it in gabion baskets to provide structural protection for the roadway piers.

	The restoration saw the removal of the reno mattresses and the introduction of boulders to create pools, diversify flow and collect sediment. These boulders were set in concrete to prevent their movement in high flows. Timber extraction of non-native conifer plantation. Planting of native broadleaf tree species.
