How much forest has Luoyang lost?
There was almost no forest around Luoyang 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 in 2000

- Overall change
- +452 hamore forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Luoyang grew from about 434 hectares to 886 hectares, a net gain of about 452 hectares (+104%). New forest grew on about 455 hectares, while 2 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.
