Project summary

Edit project overview to modify the project summary.

The River Glaven is a chalk stream in North Norfolk. The project is on stretch of the river that was made wider by dredging about four years ago. These works will help the river to recover its natural state, enhancing habitat and improving its ecological status.

Monitoring surveys and results

Edit project overview to modify the Monitoring survey and results.

Enhanced habitat along approx. 70 meters of the river Next steps: To monitor the impact of these improvements to inform plans for further works along a much longer stretch.

Lessons learnt

Edit project overview to modify the lessons learnt.

The work was carried out by a joint NRT/RGFA work party which enabled sharing of expertise between the two parties.
