Countryfile launches Plant Britain, an ambitious two-year challenge aimed at galvanising everyone in the nation to get planting - no matter where you live or how large or tiny a space you may have - to help combat climate change and at the same time, boost our wellbeing and wildlife.

Matt Baker is in Cheshire, planting the very first trees in what will become the Countryfile Plant Britain wood, while Anita Rani is in her home town of Bradford, helping residents of the Canterbury Estate to plant trees in their front gardens and at the local primary school. Anita is also on her home turf in Hackney, discovering how her local area is going green with help from voluntary organisation Tree Musketeers.

Margherita Taylor is at Wytham Woods in Oxfordshire, discovering exactly how trees capture carbon. Steve Brown is in Neath, south Wales, to learn which trees to plant in which location, while John Craven discovers a micro-forest close to his home and plants a simple window box to demonstrate how you can still do your bit even if your outdoor space may just be a window ledge. Ellie Harrison climbs high at Westonbirt Arboretum in Gloucestershire, finding out how trees function as a vital life support system for Britain’s wildlife.

There are also special messages from such well-known tree lovers as HRH The Prince of Wales, Dame Judi Dench and Brian May. Show less
