Comparing satellite maps from 2000 and 2020, the forest around Yogyakarta stayed about the same size, at about 13,400 hectares: new forest grew on about 325 hectares, and about 334 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.

Frequently asked
Questions about Yogyakarta
What is the air quality (AQI) in Yogyakarta right now?
The latest reading for Yogyakarta shows an AQI of 58 (Moderate), measured Nov 11, 23:00 local time by the Sleman, Indonesia ground monitoring station, 7.9 km away, via OpenAQ. The main pollutant is PM2.5. Unusually sensitive people should consider limiting long outdoor exertion.
Is it safe to exercise outside in Yogyakarta today?
At AQI 58 (Moderate): fine for most people; unusually sensitive people should take long or hard exercise easier. Windows: fine to open; close them if you are sensitive to pollution. Masks: not needed for most people. The reading changes through the day, so check again before a long run or ride.
What has the air quality in Yogyakarta been like this week?
Over the last 7 days, the CAMS air-quality model put Yogyakarta's daily AQI at 106 on average, from 79 on Nov 5 to an hourly peak of 201 on Nov 8. On 5 of those days the average was above 100, unhealthy for sensitive groups.
Is Yogyakarta'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 Yogyakarta lost since 2001?
Since 2001, the area within 10 km of Yogyakarta has lost about 65 hectares of forest (about 91 football pitches): 1.1% of the forest it had in 2000. Most of it (62%) was deforestation, forest cleared for good, mainly for towns and roads. Comparing satellite maps from 2000 and 2020, the forest around Yogyakarta stayed about the same size, at about 13,400 hectares: new forest grew on about 325 hectares, and about 334 hectares were lost.
What is the tree count in Yogyakarta?
Yogyakarta has an estimated 26,704 trees across the 12.57 km² measured — 8.5% tree cover, 21 percentage points short of the 30% tree-cover target set for this area.
How many more trees does Yogyakarta need?
Yogyakarta needs roughly 67,544 more trees to close a 21-point shortfall against its 30% tree-cover target — about 1,486 t of extra CO₂ absorbed per year once grown.
How are Yogyakarta's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Yogyakarta, via OpenAQ; the 7-day trend is the Open-Meteo / CAMS model's estimate. 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 Yogyakarta; the tree count is an estimate derived from that cover.
