Comparing satellite maps from 2000 and 2020, the forest around Taitung grew from about 6,490 hectares to 6,950 hectares, a net gain of about 462 hectares (+7.1%). New forest grew on about 578 hectares, while 116 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 is Taitung'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 Taitung; 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.
