Countryfile is deep in Gloucestershire exploring some woodland treasures. Julia Bradbury is at the National Arboretum in Westonbirt, finding out why workers at this haven for more than 16,000 trees are about to cut down one of its oldest residents.

At a secret woodland location across the border in Wiltshire, John Craven is on the trail of home-grown black gold; English truffles are thriving, thanks to our rainy summer.

John also finds out what it takes to create an Olympic dressage champion, when he visits Carl Hester's gold-medal winning stables.

Not too far away, in the Forest of Dean, Adam experiences a true woodland tradition when he meets up with the commoners who have the right to graze their sheep on the forest floor.

Meanwhile, Tom Heap has discovered that more than double the number of tree diseases have crossed the Channel in the last ten years compared to the whole of the last century, and there are many more waiting in the wings. He investigates what more, if anything, can be done to protect our trees.
