Autumnwatch: Ask Iolo Williams a question
The guest presenter for the penultimate show on 18 November is wildlife expert and all-round good sort, Iolo Williams.
Iolo grew up in the north Wales town of Llanwddyn, near Lake Vyrnwy east of Dolgellau. He spent 14 years with the RSPB as a field and regional co-ordinator before springing on to the airwaves as a popular wildlife broadcaster.

The Autumnwatch team have set Iolo the challenging of finding and catching one of Wales’ most elusive creatures, the sea trout.
During their autumn journey, the sea trout travel upstream from estuaries to spawn. This long journey is an amazing sight as thousands of individual trout swim sections, jump weirs and step up the fish ladders to find a safe place to breed. Have you ever wondered what a fish ladder is? Where fish go on migration? Post your fishy questions for Iolo below.

Iolo has presented shows including Iolo's Special Reserves, Iolo's Natural History of Wales and Nature's Top 40 alongside our very own Chris Packham. This year he brought us Wild Wales which took us on a breathtaking flight across Wales before plunging us into the dark claustrophobic caves of the Brecon Beacons.
