Project summary

Edit project overview to modify the project summary.

This project will aim to target catchment restoration by (i) initiating changes to agricultural land management including arable reversion to extensively managed permanent grassland and broadleaved woodland (ii) creating new wetland habitats through temporary flood storage & water retention areas on farmland (iii) enhancing and maintaining river channels (iv) upgrading channels and ditches (v) improvements to agricultural soil management (vi) awareness raising for communities (vi) monitoring to demonstrate positive change and (vii) reporting and disseminating best practice.
