How much forest has Jiangyin lost?
Since 2001, the area within 10 km of Jiangyin has lost about 15 hectares of forest (about 20 football pitches): 5.5% of the forest it had in 2000. Most of it was lost to logging, so much of it can grow back. About 3 hectares (21%) was deforestation: forest cleared for good for farms, mines or towns.

Comparing satellite maps from 2000 and 2020, the forest around Jiangyin grew from about 2,240 hectares to 3,320 hectares, a net gain of about 1,080 hectares (+48%). New forest grew on about 1,090 hectares, while 4 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.

What is the tree count in Jiangyin?
Jiangyin has an estimated 55,071 trees across the 12.52 km² of land measured — 17.6% tree cover, 12 percentage points short of the 30% tree-cover target set for this area.
How many more trees does Jiangyin need?
Jiangyin needs roughly 38,800 more trees to close a 12-point shortfall against its 30% tree-cover target — about 853.6 t of extra CO₂ absorbed per year once grown.
How are Jiangyin'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 Jiangyin; the tree count is an estimate derived from that cover.
