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 and be credited for it.

Research from a distance finds the famous trees. It misses the one on the corner that everyone in the neighbourhood walks past, the one with the story attached, the one that is only obvious if you live there. That gap is why this page exists.

Everything sent in gets checked against independent sources, and the location gets verified, because a wrong pin is worse than a missing tree. Confirmed trees get their own page with your credit on the city. What cannot be confirmed waits instead of going live half-true. To be straight with you about what you get: your name on the city you mapped, not a login or a profile. Those may come later.

Map your whole city

The big one. Tell us which city and which trees belong on its list. You do not need ten, and you do not need to write anything polished. Names and rough locations are enough; the research, the checking and the writing happen here.

Map my city

Or just one tree

Saw something remarkable and know roughly where it stands? That is enough. One tree in a city we have never touched is often the thing that starts it.

Send one tree

What helps most

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.
