Tree opportunity
Overview
This layer shows the potential increase in tree cover as a share of all surface area if all plantable areas reached their achievable planting potential. Values are calculated for each 100-meter grid cell and represent the change in total tree cover based on target levels derived from areas in the city where tree planting is already highly implemented.
Function
To identify where additional tree planting could most increase canopy cover and support cooling strategies.

Cautions
The tree opportunity layer is an estimate of the potential for increasing tree cover. Targets values for tree cover are calculated per plantable LULC class from the WRI OpenUrban dataset using percentile values of the existing tree cover—the 30th percentile for barren and built up other, the 50th percentile for green space other, and the 90th percentile for public open space and street right-of-ways. Plantable street right-of-ways are calculated as the 5 meters adjacent to roads. This data useful for understanding where the highest gains are possible.
