encompassing the following
River restoration including use of plastic mesh to stabilise silt bed before bed raising with gravel. Creation of point bars, bank reprofiling and rebuilding and fencing were also part of the project.
Monitoring surveys and results
Invertebrate monitoring prior to work found only worms and leeches. Freshwater shrimp and blackfly larvae colonised very rapidly and a few months later mayfly larvae, caddis larvae and water beetles were also present.
So far the mesh is working well, and unlikely to fail for a long time. It will be interested to revisit in 10 or 20 years to see what happens to the new gravel bed. Invertebrates colonised the new habitat quickly and it is hoped that trout will spawn there one day.
Cattle drinks were created with a gravel bed and fencing - in hindsight more gravel in each would have been better.
