How much forest has Zhijiang lost?
There was very little forest around Zhijiang in 2000, about 24 hectares, and about 4 hectares 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.

The worst year was 2007, when about 1 hectare of forest were lost.

Comparing satellite maps from 2000 and 2020, the forest around Zhijiang grew from about 482 hectares to 550 hectares, a net gain of about 68 hectares (+14%). New forest grew on about 82 hectares, while 13 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 much forest has the area around Zhijiang lost since 2001?
There was very little forest around Zhijiang in 2000, about 24 hectares, and about 4 hectares 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.

New forest grew on about 82 hectares, while 13 hectares were lost.
What is the tree count in Zhijiang?
Zhijiang has an estimated 41,317 trees across the 8.43 km² of land measured — 19.6% tree cover, 10 percentage points short of the 30% tree-cover target set for this area.
How many more trees does Zhijiang need?
Zhijiang needs roughly 21,923 more trees to close a 10-point shortfall against its 30% tree-cover target — about 482.3 t of extra CO₂ absorbed per year once grown.
How are Zhijiang'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 Zhijiang; the tree count is an estimate derived from that cover.
