Comparing satellite maps from 2000 and 2020, the forest around Lucena shrank from about 11,500 hectares to 10,300 hectares, a net loss of about 1,190 hectares (−10%). New forest grew on about 116 hectares, but 1,310 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 Lucena?
Lucena has an estimated 118,019 trees across the 12.39 km² of land measured — 38.1% tree cover, already past the 30% tree-cover target set for this area.
How many more trees does Lucena need?
Lucena has already reached its tree-cover target, so no additional trees are needed to close the gap.
How are Lucena'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 Barangay 9; the tree count is an estimate derived from that cover.
