Ancient Tree Inventory

Ancient trees are living relics of incredible age that inspire in us feelings of awe and mystery. They have helped shape our history, and will help shape our future if we let them.

The Ancient Tree Inventory (ATI) is a living database of ancient trees. The ATI began in 2004, as a joint venture with the Tree Register of the British Isles and the Ancient Tree Forum. By December 2015, over 150,000 hand-picked trees had been recorded across the UK.

There are still lots of amazing ancient trees still to be discovered and recorded as they can be found anywhere and everywhere. If you find a tree that is not on the map then please add it and upload an image as well. The growing database will give us a much better understanding of the number of ancient trees across the UK. Recording them is the first step towards cherishing and caring for them.
