Help us create a map of Britain's trees and learn about some of the environmental benefits they provide with the Treezilla app. You can record tree locations, species and size and the system calculates the environmental benefits ('ecosystem services') that each tree provides, for example how much pollution they remove from the air.

You need to be registered with the site and logged in through the app to add trees. You'll also need a data connection (wifi or mobile data) to view the map and add trees.

To add a tree just click the + sign in the top right hand corner and follow the instructions in the app to add a marker to the map.

You can then measure the tree size and identify it, this information is used to automatically calculate the ecosystem services.

The system also allows you to add lots more information about the tree such as pests and diseases, tree condition etc

You can see details of trees mapped near you or added recently.

Get together with friends to turn your town into an arboretum!

Treezilla is a project led by the Open University with partners Forest Research and Treeconomics. This app has been produced with funding from the Natural Environment Research Council under project VITAL.

This is a beta release of the app. There may be some glitches as we continue to develop it.
