How realistic is your target to increase tree cover across London by 5 per cent (from 20 to 25 per cent) by 2025, given your recent analysis of aerial imagery showed little change over the last decade?

The Measuring Tree Canopy Cover in London report published last year established a baseline of tree cover at around 19.5 percent. The study was undertaken in order to establish a baseline from which repeatable analysis and evaluation can be undertaken. The report noted that recently planted trees will take several years to mature before they are detectable on aerial imagery.

The amount of tree planting in London suggests that we are heading in the right direction. It is estimated that approximately 400,000 trees have been planted in London by the GLA and the RE:LEAF partnership since 2011, including 20,000 street trees. In addition to this trees are being planted by other landowners and managers including London boroughs and developers.

The GLA will repeat the aerial imagery analysis in order to detect changes over time.
