For the final part of the journey Christina canoes with Julie Doherty from Avon Wildlife Trust. As they paddle along they chat about the river as wildlife corridor and how we can all play our part in tackling the ecological crisis. In Eastville Park they come across wildlife photographer Robbie Deville photographing kingfishers. And Christina meets Melvin Woods from the Environment Agency. They talk about flood management and urban dilemmas as they walk through the streets of Bristol, where the river flows unseen beneath their feet, until it finally meets the River Avon
