How much forest has Laizhou lost?
There was very little forest around Laizhou in 2000, about 16 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.
2017: satellite photo from June 2017 of a 5 × 5 km area in the city center.
The worst year was 2006, when about 1 hectare of forest were lost.

Causes for 2025 are estimates, based on what caused forest loss in the same places up to 2024.

- +148 hamore forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Laizhou grew from about 301 hectares to 449 hectares, a net gain of about 148 hectares (+49%). New forest grew on about 162 hectares, while 14 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.
