Comparing satellite maps from 2000 and 2020, the forest around Denpasar stayed about the same size, at about 6,560 hectares: new forest grew on about 347 hectares, and about 447 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 Denpasar been like this week?
Over the last 7 days, the CAMS air-quality model put Denpasar's daily AQI at 64 on average, from 57 on Nov 4 to an hourly peak of 89 on Nov 6. No day averaged above 100, the level where the air turns unhealthy for sensitive groups.
Is Denpasar'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 Denpasar lost since 2001?
