This week's Living World sees presenter Chris Sperring heading to Hampshire where with native lime tree specialist Hugh Milner they embark on a journey into the remarkable life of the UK's native lime trees. Most people's association with lime is a sticky mess on car windscreens from street planted non-native common lime. This is a hybrid of the 2 native species of lime tree in Britain, the small leaved lime and the large leaved lime. The bark, or more importantly the sap from the bark is also a great delicacy for great spotted woodpeckers, who it is now believed, after drilling their holes, wait until insects become trapped in the sap to take back to their young in the nest. More surprisingly lime trees can walk across a landscape, as they have the ability to regenerate from fallen timber or if branches make contact with the ground. Producer: Andrew Dawes
