Comparing satellite maps from 2000 and 2020, the forest around Bozhou grew from about 313 hectares to 1,100 hectares, a net gain of about 789 hectares (+252%). New forest grew on about 788 hectares, while under 1 hectare was 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.

What is the tree count in Bozhou?
Bozhou has an estimated 40,077 trees across the 11.79 km² of land measured — 13.6% tree cover, 16 percentage points short of the 30% tree-cover target set for this area.
How many more trees does Bozhou need?
Bozhou needs roughly 48,328 more trees to close a 16-point shortfall against its 30% tree-cover target — about 1,063 t of extra CO₂ absorbed per year once grown.
How are Bozhou's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Qiaocheng 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 Qiaocheng District; the tree count is an estimate derived from that cover.
