Julian and the team are in Walsall where they visit Joan Lockley who runs her very own ‘Hedgehog Hosprickal’. They are able to track the progress of one of Jo’s precious patients after he is released back into the wild and she is left feeling overwhelmed with emotion at the prospect of tracking her hedgehog’s movements. They then pay a visit to Lichfield to meet Kate MacRae who captures the activity of our feathered friends, with numerous cameras placed around her garden and inside her bird boxes, which she streams onto the Internet. After making his way to Stowe Maries, Julian talks to Russell Savoury and turns his attention to the water vole, a creature that is quickly disappearing due to reintroduced mink and loss of habitat.

Julian travels to the Farne Islands with Ben Burville where it is time for a costume change as he puts on a wetsuit. He then gets the chance to swim with the largest carnivorous mammal in Britain, an experience that certainly gets the star’s seal of approval. He then makes his way to Northwich in Cheshire to meet Dave Culley, who reignited his childhood passion for wildlife following a couple of life-changing motorcycle accidents. Julian then visits Hazel Ryan in Herne Bay where he comes face to face with the super sleepy dormouse.

In this final episode, Julian waves goodbye to the West End and ventures into the wilds of Yorkshire in search of an artist whose intricate paintings are inspired by his snaps of the surrounding wildlife. Nature Nut Robert Fuller’s latest muse is the kestrel and he’s been trying to capture one in flight for some time, so Julian asks award-winning cameraman John Waters to step in. John’s high-speed equipment is just the ticket, it can record 1500 frames per second, with ordinary cameras managing just 25. Julian remarks: “It is, quite frankly, the Beyoncé of the camera world.” Next, it’s up to the Scottish Highlands for a bathroom disco with a female fish-packer in pursuit of the elusive pine martin. Muirne Buchanan lives on Loch Torridon, 300 miles north of the Scottish border and her garden happens to be inhabited by these cat-sized cousins of the badger and the weasel. With just 3,000 left in the UK, they’re a rare sight and it’s up to John to get the sharp-toothed fellas on film. But, will they care for the custard creams that Julian and Muirne have so carefully laid out for them? Finally, our fairy godmother heads to Perth to catch up with Bob Smith, ‘The Beaver Man’, on a canoe. This Nature Nut has been hoping to see a baby beaver, also known as a kit, and Julian won’t stop until they’ve got the evidence they need to rest assured that this furry family’s lineage will continue.
