These figures cover everything within 10 km of the city center, a wider area than the report above, because forest is usually lost at a city's edges.

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 Bassiknou; the tree count is an estimate derived from that cover.
