Use of site won materials
Five Rivers were commissioned by the Wiltshire Wildlife Trust to carry out river restoration and habitat enhancement works on the River Avon.
The work was carried out on MOD land so permissions and daily communications were vital.
Multi skilled site team carried out a variety of works including water vole searches, excavations, tree works, pinning large woody material and installing imported gravels in a safe and efficient manner.
The restoration project sought to reinstate natural form and flow function by utilising site won materials such as gravels and timber.
Restoration works were undertaken in order to restore flow velocity, enhance channel dynamics, and thus in-channel plant communities, invertebrate numbers and fish habitat
Improved water quality
Increased wetland habitats
Floodplain reconnected to the river
Increased variety of in-channel habitats
