- Overall change
- −1,260 haless forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Tayabas shrank from about 25,600 hectares to 24,400 hectares, a net loss of about 1,260 hectares (−4.9%). New forest grew on about 38 hectares, but 1,300 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 Tayabas?
Tayabas has an estimated 193,522 trees across the 12.57 km² measured — 61.6% tree cover, already past the 30% tree-cover target set for this area.
How many more trees does Tayabas need?
Tayabas has already reached its tree-cover target, so no additional trees are needed to close the gap.
How are Tayabas'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 San Diego Zone II; the tree count is an estimate derived from that cover.
