Project summary

Edit project overview to modify the project summary.


Riverbank enhancements and naturalisation. The bank is currently degraded, base and in poor condition. Some sections are also toe-boarded and over-shaded. The section could be improved to increase habitat diversity and the quality of the river corridor. This is of particular relevance to support future populations of water voles along the river.

Monitoring surveys and results

This case study hasn’t got any Monitoring survey and results, you can add some by editing the project overview.

Lessons learnt
