Project summary

Edit project overview to modify the project summary.


Installation of woody debris and berms to increase habitat diversity: The Reepham Stream is a tributary of the River Wensum located between Reepham and Cawston in Norfolk. Historic management and land drainage has led to a river channel that is deep in relation to surrounding ground, and contains little variation in habitat. Working with the IDB and NRT, a scheme was designed that would not increase flood risk but would enhance the habitat in stream to help improve its ecological status. This work will compliment the River Wensum Restoration Strategy.

Monitoring surveys and results

Edit project overview to modify the Monitoring survey and results.


With utilisation of plant materials and resources already on site, minimising mobilisation costs for river restoration; to improve habitat diversity in a heavily modified waterbody; to give greater flow diversity helping to address low dissolved oxygen issues. By addressing a low dissolved oxygen concentrations and mitigation measures needed for heavily modified designation.

Lessons learnt

Edit project overview to modify the lessons learnt.


Discussions with partners can often identify opportunities for projects giving multiple benefits- continuous work with the IDB on similar restoration schemes.
