Countryfile: Julia Bradbury and John Craven Explore the Usk Valley

Known as the gateway to Wales, the Usk is less well known than its neighbour, the Wye, but it certainly matches it in beauty. Julia finds out what is being done to conserve eels in its rivers and lakes, while John takes a look at the building providing the perfect home for one of our rarest creatures - the lesser horseshoe bat. Elsewhere, Tom investigates how a comeback in coal is affecting our countryside and the communities that live there. And Adam shows his top rams at a rare breed show and sale, where he is hoping they will catch the judge's eye and win a rosette or two
