Comparing satellite maps from 2000 and 2020, the forest around Apopa stayed about the same size, at about 21,100 hectares: new forest grew on about 165 hectares, and about 439 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 centre, a wider area than the report above, because forest is usually lost at a city's edges.

How much forest has the area around Apopa lost since 2001?
Since 2001, the area within 10 km of Apopa has lost about 1,390 hectares of forest (about 1,900 football pitches): 9.1% of the forest it had in 2000. Most of it (97%) was deforestation, forest cleared for good, mainly for farms, pasture and plantations. Forest loss is slowing down: about 33 hectares a year in 2021–2025, down from 59 hectares a year in 2016–2020. Comparing satellite maps from 2000 and 2020, the forest around Apopa stayed about the same size, at about 21,100 hectares: new forest grew on about 165 hectares, and about 439 hectares were lost.
How is Apopa's tree cover and air quality measured?
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 Urb La Ermita 2; the tree count is an estimate derived from that cover. 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.
