Comparing satellite maps from 2000 and 2020, the forest around León shrank from about 8,380 hectares to 8,190 hectares, a net loss of about 186 hectares (−2.2%). New forest grew on about 479 hectares, but 665 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 is the tree count in León?
León has an estimated 122,208 trees across the 12.57 km² measured — 38.9% tree cover, already past the 30% tree-cover target set for this area.
How many more trees does León need?
León has already reached its tree-cover target, so no additional trees are needed to close the gap.
How are León'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 Barrio El Sagrario; the tree count is an estimate derived from that cover.
