Comparing satellite maps from 2000 and 2020, the forest around Magelang stayed about the same size, at about 21,900 hectares: new forest grew on about 192 hectares, and about 154 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 has the air quality in Magelang been like this week?
Over the last 7 days, the CAMS air-quality model put Magelang's daily AQI at 109 on average, from 93 on Nov 5 to an hourly peak of 185 on Nov 6. On 6 of those days the average was above 100, unhealthy for sensitive groups.
Is Magelang's AQI the same as Indonesia's ISPU?
No. Airleaf shows the US EPA Air Quality Index (AQI), the scale used by IQAir and most air-quality apps. Indonesia's official index is the ISPU (Indeks Standar Pencemar Udara), published by the environment ministry from its own monitoring stations. Its bands are 0–50 Baik (good), 51–100 Sedang (moderate), 101–200 Tidak Sehat (unhealthy), 201–300 Sangat Tidak Sehat (very unhealthy) and over 300 Berbahaya (hazardous). The two indexes use different breakpoints and averaging times, so the same air can score differently on each.
How much forest has the area around Magelang lost since 2001?
Since 2001, the area within 10 km of Magelang has lost about 95 hectares of forest (about 130 football pitches): under 1% of the forest it had in 2000. Most of it (51%) was deforestation, forest cleared for good, mainly for farms, pasture and plantations. Comparing satellite maps from 2000 and 2020, the forest around Magelang stayed about the same size, at about 21,900 hectares: new forest grew on about 192 hectares, and about 154 hectares were lost.
What is the tree count in Magelang?
Magelang has an estimated 103,152 trees across the 12.54 km² of land measured — 32.9% tree cover, already past the 30% tree-cover target set for this area.
How many more trees does Magelang need?
Magelang has already reached its tree-cover target, so no additional trees are needed to close the gap.
How are Magelang'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 Magelang; the tree count is an estimate derived from that cover.
