John Craven and Julia Bradbury head to rural Leicestershire. It may look like an oasis of peace and tranquillity, but look closer and it's a hive of activity. Tucked away in the middle of England, John finds a military training camp with a difference; he meets the British Army's new four-legged recruits as they are put through their paces. Julia finds out about the Woodland Trust's plans to get us all planting trees in 2012. The Trust sets Julia and John a challenge to start planting the biggest native woodland in the UK in an empty field in Leicestershire. The aim is to plant 2,000 saplings in just one hour. It's team Bradbury versus team Craven. Tom Heap is in Scotland asking whether it's time to bring back big cats. Down on the farm, Adam's on tenterhooks waiting for news on whether his Highland bull - Eric - is going to be a dad again.
