Comparing satellite maps from 2000 and 2020, the forest around Singaraja stayed about the same size, at about 10,700 hectares: new forest grew on about 182 hectares, and about 198 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 Singaraja been like this week?
Over the last 7 days, the CAMS air-quality model put Singaraja's daily AQI at 72 on average, from 65 on Nov 9 to an hourly peak of 113 on Nov 7. No day averaged above 100, the level where the air turns unhealthy for sensitive groups.
Is Singaraja'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 Singaraja lost since 2001?
Since 2001, the area within 10 km of Singaraja has lost about 154 hectares of forest (about 220 football pitches): 1.6% of the forest it had in 2000. Most of it (91%) was deforestation, forest cleared for good, mainly for farms, pasture and plantations. Comparing satellite maps from 2000 and 2020, the forest around Singaraja stayed about the same size, at about 10,700 hectares: new forest grew on about 182 hectares, and about 198 hectares were lost.
What is the tree count in Singaraja?
Singaraja has an estimated 56,096 trees across the 9.35 km² of land measured — 24.0% tree cover, 11 percentage points short of the 35% tree-cover target set for this area.
How many more trees does Singaraja need?
Singaraja needs roughly 25,711 more trees to close a 11-point shortfall against its 35% tree-cover target — about 565.6 t of extra CO₂ absorbed per year once grown.
How are Singaraja'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 Singaraja; the tree count is an estimate derived from that cover.
