What is the tree count in Standerton?
Standerton has an estimated 33,615 trees across the 12.57 km² measured — 10.7% tree cover, 19 percentage points short of the 30% tree-cover target set for this area.
How many more trees does Standerton need?

How are Standerton's air quality and tree cover measured?
Air quality comes from ground monitoring stations via OpenAQ where one reports nearby, and otherwise, as here, from the Open-Meteo / CAMS model, which may differ from street-level monitors. Tree cover is measured from Sentinel-2 L2A (ESA Copernicus) via Earth Search satellite imagery at 10 m detail across a 2 km radius around Standerton; the tree count is an estimate derived from that cover.
