Countryfile

Matt and Margherita are in North Wales where Matt discovers how miniature technology could tell us more about the habits of one of our best-loved insects. He's shown how tiny antennae are strapped to individual bees which are then tracked by drones. Matt also meets the entrepreneurial young beekeeper already farming her own bees and selling the honey to businesses nearby. Margherita takes a ride on the famous Blaenau Ffestiniog railway along with people living with dementia and their carers. The trip is the brainchild of Emma Jayne Quaeck who saw how being out in nature helped her own mother's condition. Margherita also heads underground to see how old slate mines are being used to help age prize-winning local cheese. John is joined by fellow judges Cerys Matthews and Simon King to announce the final 12 in this year's Countryfile Photographic Competition, and Adam comes face to face with a cattle breed that is shaking up smallholding.
