Project summary

Edit project overview to modify the project summary.


Improvement works on the River Meden. The work involved installing fencing, cattle drink and pasture pump, to prevent poaching of the river bank. Poaching of river banks leads to run off and erosion, damaging soils and polluting watercourses with an excess of sediment and nutrient. Protected over 250m of the river. Riverbanks will be allowed to recover and water quality improved. Vegetation cover is ideal Water Vole habitat and bird breeding sites.

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

Edit project overview to modify the lessons learnt.


Has encouraged pride and ownership by raising awareness, educating and working with the local farmer. By using the site as a demonstration, there are opportunities for wider work to improve areas affected by rural diffuse pollution. Next steps are to promote the success of the project through social media. To support the use of the project site as a demonstration area, for example through farm walks. Support future projects in the area to deliver further outcomes.
