Across the UK days are warmer, brighter and longer. In the countryside, the air is filled with birdsong and the scent of flowers. Spring has sprung!
Every day this week, John Craven and the Countryfile Diaries team - Keeley Donovan, Jules Hudson, Paul Martin, Margherita Taylor and Steve Brown - bring you the most interesting stories of the season.

Meanwhile, Keeley's dipping into the surprises inside one of our favourite health foods, and meeting a farmer who's bringing an Icelandic superfood yoghurt to Yorkshire. Margherita's on Exmoor, finding out how keen-eyed volunteers played a vital role to protect against butterfly crime. And Paul's on his smallholding in Wiltshire, finding out everything you need to know if you're hoping to hear the tiny patter of piggy trotters this season.
