- −397 haless forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Catania shrank from about 2,320 hectares to 1,920 hectares, a net loss of about 397 hectares (−17%). New forest grew on about 95 hectares, but 493 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.

New forest grew on about 95 hectares, but 493 hectares were lost.
What is the tree count in Catania?
Catania has an estimated 43,802 trees across the 12.26 km² of land measured — 14.3% tree cover, 16 percentage points short of the 30% tree-cover target set for this area.
How many more trees does Catania need?
Catania needs roughly 48,090 more trees to close a 16-point shortfall against its 30% tree-cover target — about 1,058 t of extra CO₂ absorbed per year once grown.
How are Catania'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 Catania; the tree count is an estimate derived from that cover.
