Matt Baker and Jules Hudson head for Exmoor to discover how the native ponies are being given a new lease of life, what's being done to protect crayfish from the threat of foreign invaders, and why you need to stray off the beaten track if you want to discover the area's hidden secrets. John Craven investigates the decline of some of our favourite farmland birds, and it's a tense time down on the farm as Adam Henson finds out if his prize cattle are finally clear of TB.
