Tree canopy cover map

London has more than 8 million trees, covering around 21 per cent of the capital’s land area. The Mayor has committed to increasing tree canopy cover by 10 per cent by 2050. To help achieve this aim we have created a detailed map with Breadboard Labs which helps us analyse tree canopy cover by area.

About the map

Previous estimates of London's tree cover were based on statistical sampling taken from different areas of the capital. This new map uses high-resolution aerial imagery of the whole of London to analyse tree cover using machine-learning techniques. It will help us pinpoint exactly where trees are and which parts of London have low tree cover and should be targeted for tree planting projects.

We have made this data publicly available so anyone can download it and use it for further research.
