Welcome to the Ancient Tree Inventory
Mapping the oldest and most important trees in the UK.
They can live for hundreds of years. And there are more of them in the UK than many other European countries.
Help protect our valuable tree heritage. Let us know if you see any ancient or old trees and put them on the map. There are already more than 160,000 trees listed but there are thousands more to add.
We need your help to find them.
May 2021 Update: new mapping features and pin design coming very soon. Please read our new blog post here to find out more.
