Become your city's tree guide
This map is missing far more cities than it has, and the trees that matter most are the ones locals already know about. If you know your city's remarkable old trees, you can put them on the map.
You know the trees we miss: the one on the corner everyone in the neighbourhood walks past, the one with a story only people who live there know.
We check every tree you send, and the location above all, because a wrong pin is worse than a missing tree. We do not publish your name anywhere on the site, and you don't need to give it.
You need an account to send a tree, so you can see what happened to each one you sent.
Writing about us? The numbers, image licences and caveats live on the press page.
What helps most
- Where exactly it stands. A street corner, a park entrance, or a dropped pin from Google Maps. The single most useful thing you can give us.
- Why it is remarkable. Old, enormous, strange, or tied to a local story.
- How thick the trunk is. You can measure it by putting your arms around it, and one adult hug is about a metre and a half.
- How you know. A link, a book, a plaque, or just that you grew up next to it.
- A photo you took yourself, if you have one. We can only publish photos that are yours to share or openly licensed.
Or fix something
Spotted a wrong location, an age that looks off, or a tree that has fallen since we wrote about it? Those corrections are just as valuable. Send a correction and say what is wrong.
