How much forest has Yangzhou lost?
There was almost no forest around Yangzhou in 2000, so there has been almost nothing to lose since. Only fairly dense woodland counts as forest in these maps, so scattered street and garden trees don't show up here.

Forest gained and lost, 2000–2020
- Forest in 2000
- 1,420 ha
- Forest in 2020
- 2,180 ha
- Overall change
- +757 hamore forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Yangzhou grew from about 1,420 hectares to 2,180 hectares, a net gain of about 757 hectares (+53%). New forest grew on about 761 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.
