Project summary

Edit project overview to modify the project summary.

The SCRIP project is a partnership that will use CRF funds to manage restoration work to deliver habitat improvements on the rivers that drain South Cornwall and the St Austell bay area. The partnership, led by the Westcountry Rivers Trust, has been carrying out river restoration and addressing the causes of Water Framework Directive issues together for many years.

Through restoration work, the project will address issues including: flow modifications and habitat degradation; diffuse pollution from agriculture; barriers to fish migration; interrupted conveyance of river gravels reducing spawning habitats for salmonids; impacts from china clay extraction and historic mining
