Restoring Welsh Rivers summit - we speak to the Archbishop of Wales about why the Church in Wales is getting involved in tackling our waterways and we hear how the Dean of St David's in Pembrokeshire is "doing the little things" and caring for a small river that runs by the Cathedral. Polder fields - a Natural Resources Wales' project to restore saltmarsh along the Rhumney Great Wharf by reinstating and extending the sedimentation polders - small fences on the mudflats. and for our Bird of Conservation concern, we're on a farm in Pembrokeshire to feed the Yellowhammers.
