Chris Packham, Michaela Strachan, Gillian Burke and Iolo Williams present a week of programmes showcasing wildlife around the UK live from the Dell of Abernethy in the Cairngorms. The first episode features a guest appearance by astronaut Tim Peake, who explains how the seasonal cycle was influenced by a giant collision in space billions of years ago, and a Yorkshire GP who has befriended a colony of North Sea seals. Plus, the results of citizen science project Gardenwatch, in which members of the public were asked to survey the animals in their gardens.
