This map is an initial attempt to visually present London tree data. The majority of the data is for street trees but also includes some park trees. The map shows the locations and species information for over 700,000 trees. The recent London iTree report estimated that there are over eight million trees in London, so the map is only a partial illustration of trees in London

There are several potential benefits to the public sharing of tree data. We hope that visualising tree data, and providing access to it in one place, will help to raise the public profile of the important contribution of trees to our urban environment and also provide operational benefits for tree managers. Sharing and standardising data could provide essential information for the strategic management of the urban forest. For example, it could help to assess species diversity and threats from pests and plant diseases across London, and also help identify areas for additional planting.

The data was provided in 2014-15. There is more explanation of the data below the map, and the data is available on the London Datastore.
