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 190,000 trees listed but there are thousands more to add.
We need your help to find them.
Where do ancient trees grow? Explore the UK’s ancient tree heritage with our map.
And you can view any trees you’ve added.
