鲍鱼tv

In 1995 a young RSPB worker called Iolo Williams was filmed for a 鲍鱼tv documentary about Snowdonia. Since then Iolo has become one of Wales's favourite broadcasters.

In this series he looks back at some of his past programmes and revisits the locations and wildlife featured in them. He asks what has changed and if conservation work has had an effect, or if the modern world is pushing more wildlife to the brink.

In this first programme, Iolo travels around the Welsh coast, a vulnerable environment but one that's full of new discoveries.
