Here's a thought... what if all our upland rivers were left unmanaged? What would happen if they were left to re-wild? We teamed up with Dr Rhys Jones ("Rhys Jones's Wildlife Patrol" BBC1) and put together a very short video about the importance of our upland rivers. It's not a groundbreaking documentry, far from it; it's merely a trailer that looks at various possible scenarios. It was made for Nerc-Duress based at Cardiff Uni as part of a general awareness initiative.
