What is happening to Britain’s horse-chestnut trees? Since 2002 Britain’s conker trees have been under attack from a non-native moth – and you can help scientists at the Universities of Bristol and Hull monitor what’s happening. The Leaf Watch app shows you how to identify affected trees and enables you to submit geo-located leaf photos. This data will show our scientists where the moth is present within the UK today. Your reports will contribute to the Conker Tree Science research project.
