Project summary

Edit project overview to modify the project summary.

170m of tributary restoration including 0.07 ha riparian habitat. Bank reprofiling on the Pessall Brook to create 2 stage channel bays, to add a diversity of habitat to a village amenity grass area, add greater capacity for higher flows, and replace old wooden bank protection with coir rolls.

Monitoring surveys and results

Edit project overview to modify the Monitoring survey and results.

Pre-works invertebrate sampling undertaken, pre-works hydromorph geomorphology survey undertaken, fixed point photography.

Lessons learnt
