- Forest in 2000

- Overall change
- +168 hamore forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Tbilisi grew from about 3,430 hectares to 3,600 hectares, a net gain of about 168 hectares (+4.9%). New forest grew on about 235 hectares, while 67 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.

Tbilisi needs roughly 20,544 more trees to close a 7-point shortfall against its 30% tree-cover target — about 452.0 t of extra CO₂ absorbed per year once grown.
How are Tbilisi's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Isani-Samgori, via OpenAQ; the 7-day trend is the Open-Meteo / CAMS model's estimate. 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 Isani-Samgori; the tree count is an estimate derived from that cover.
