How much forest has Kayseri lost?
There was very little forest around Kayseri in 2000, about 64 hectares, and about 3 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 August 2017 of a 5 × 5 km area in the city center.
The worst year was 2005, when about 1 hectare of forest were lost.

Comparing satellite maps from 2000 and 2020, the forest around Kayseri grew from about 237 hectares to 296 hectares, a net gain of about 59 hectares (+25%). New forest grew on about 73 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.
