Does it really work without a phone signal?

Yes. Once downloaded, the map, trees and paths work offline. Fresh cow locations need a connection; offline, the map shows their last saved positions.

Yes. Free to use, with no account needed.

Where does the tree data come from?

Our tree data comes from the Epping Forest Veteran Tree Register, provided by the City of London. We know some of the data may not be completely accurate. As part of the trial, we’re working to understand the issues and improve the data, and we’ll report our findings back to the City of London. Paths, pubs, car parks and transport come from OpenStreetMap contributors.

Can I correct something that’s wrong?

Yes. Open a tree or place in the app and tap “Help check”, or add a tree that’s missing. Your reports don’t change the official record: here’s how they’re used.

How do you know where the cattle are?

GPS collars report their positions through Nofence. The map refreshes them periodically while online. Offline, you see their last saved positions, which may be out of date.

Which area does it cover?

Epping Forest and nearby pubs, stations and facilities within walking distance.

What’s with the tree tags?

Each tag identifies a tree in the Veteran Tree Register. Look up one you’ve spotted, or choose one for your next walk.

Some of the data may not be completely accurate. Please report any issues you find and we’ll pass them on to the City of London.

A weathered metal tree tag stamped with the number 27400 and code TS3, fixed to tree bark.

The app’s search screen with the number 440 entered, listing matching trees by tag number with their walking distance. — **1. Look it up.** Search veteran trees by tag, common or Latin name — or find places by name or category. Results are ranked by relevance and nearby distance.

The app’s tilted 3D map with oak markers ahead of you, and the nearest English Oaks and a monument listed by walking distance and direction. — **2. Find your way there.** Get a route that aims to favour forest paths and alleyways. Check the tag when you arrive.

The app’s detail screen for English Oak tag 18241, showing its estimated age and a walking route from your location to the tree. — **3. See its estimated age.** An estimate from recorded girth and species, where available — not an exact birthday.
