How much forest has Huangzhou lost?
There was very little forest around Huangzhou in 2000, about 42 hectares, and about 1 hectare of it has been lost since. Only fairly dense woodland counts as forest in these maps, so scattered street and garden trees don't show up here.

Comparing satellite maps from 2000 and 2020, the forest around Huangzhou grew from about 613 hectares to 845 hectares, a net gain of about 232 hectares (+38%). New forest grew on about 240 hectares, while 8 hectares were lost.
These 2000 and 2020 maps, from the University of Maryland, count any land with trees taller than 5 m as forest, including plantations and orchards. Forest that was cut or burned and had grown back by 2020 counts in both years, so the loss here is smaller than the yearly figures.
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.

How many more trees does Huangzhou need?
Huangzhou needs roughly 23,169 more trees to close a 9-point shortfall against its 30% tree-cover target — about 509.7 t of extra CO₂ absorbed per year once grown.
How are Huangzhou's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Huangzhou District, via OpenAQ; the 7-day trend is the Open-Meteo / CAMS model's estimate. 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 Huangzhou District; the tree count is an estimate derived from that cover.
