Conservation work on a valley on University of Exeter land will reduce surface water run-off and improve connectivity for freshwater biodiversity.
Starting on September 8, contractors will be working in Lower Hoopern Valley to develop a nature-based flood management solution in the Taddiforde Brook.
The University of Exeter is working with the Environment Agency and researchers from CREWW (Centre for Resilience in Environment, Water and Waste) to slow the flow of water through the Valley.
They will be installing dam-like structures known as "leaky wood spreaders", which include , gaps to allow fish and freshwater invertebrates to pass through. The works, which are expected to finish by the end up September, include creating temporary pools in the stream, which hold back water but allow water through and connect the brook to the flood plain to create wet grassland habitat.
Artificial structures will be removed that currently hinder how 'connected' the brook is for wildlife.
"Many areas of the brook have much deeper and steeper banks than it should be due to fast flows during high rainfall. It is also highly shaded which prevents aquatic plant growth. The works will increase habitats for wildlife and help protect the downstream rivers from pollution."
Some on trees on the site will be felled to construct the leaky woody dams. The focus will be on trees with the disease ash dieback, meaning they are likely to need removing, and on younger sycamores which have lower biodiversity value.
The University is asking pedestrians who pass through the valley during this period, please help our contractors keep themselves and you safe by:
· Using alternative routes if needed during construction (the public right of way will remain open).
· Following any safety signs and instructions given by contractors.
