How much forest has Saki lost?
There was very little forest around Saki in 2000, about 92 hectares, and about 20 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 February 2017 of a 5 × 5 km area in the city center.
The worst year was 2017, when about 9 hectares of forest were lost.

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

Comparing satellite maps from 2000 and 2020, the forest around Saki shrank from about 16,400 hectares to 15,400 hectares, a net loss of about 924 hectares (−5.6%). New forest grew on about 545 hectares, but 1,470 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 has the air quality in Saki been like this week?
Over the last 7 days, the CAMS air-quality model put Saki's daily AQI at 69 on average, from 60 on Nov 10 to an hourly peak of 92 on Nov 8. No day averaged above 100, the level where the air turns unhealthy for sensitive groups.
How much forest has the area around Saki lost since 2001?
There was very little forest around Saki in 2000, about 92 hectares, and about 20 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. Comparing satellite maps from 2000 and 2020, the forest around Saki shrank from about 16,400 hectares to 15,400 hectares, a net loss of about 924 hectares (−5.6%). New forest grew on about 545 hectares, but 1,470 hectares were lost.
What is the tree count in Saki?
Saki has an estimated 74,770 trees across the 12.57 km² measured — 23.8% tree cover, 6 percentage points short of the 30% tree-cover target set for this area.
How many more trees does Saki need?
Saki needs roughly 19,478 more trees to close a 6-point shortfall against its 30% tree-cover target — about 428.5 t of extra CO₂ absorbed per year once grown.
How are Saki'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 Shaki 203101; the tree count is an estimate derived from that cover.
