Comparing satellite maps from 2000 and 2020, the forest around Negara stayed about the same size, at about 16,000 hectares: new forest grew on about 192 hectares, and about 300 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 Negara
What is the air quality (AQI) in Negara right now?
The latest reading for Negara shows an AQI of 129 (Unhealthy for sensitive groups), observed Nov 11, 02:00 local time via Open-Meteo / CAMS, corrected with 2 ground-station cities within 225 km, US EPA index. The main pollutant is PM2.5. Sensitive groups should limit long or intense outdoor activity.
Is it safe to exercise outside in Negara today?
At AQI 129 (Unhealthy for sensitive groups): children, older adults and people with asthma or heart disease should cut down long or hard exercise. Windows: close them to keep the outside air out. Masks: sensitive groups: an N95 outdoors. The reading changes through the day, so check again before a long run or ride.
What has the air quality in Negara been like this week?
Over the last 7 days, the CAMS air-quality model put Negara's daily AQI at 68 on average, from 57 on Nov 9 to an hourly peak of 125 on Nov 7. No day averaged above 100, the level where the air turns unhealthy for sensitive groups.
Is Negara'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 Negara lost since 2001?
Since 2001, the area within 10 km of Negara has lost about 750 hectares of forest (about 1,100 football pitches): 5.2% of the forest it had in 2000. Most of it (93%) was deforestation, forest cleared for good, mainly for farms, pasture and plantations. Comparing satellite maps from 2000 and 2020, the forest around Negara stayed about the same size, at about 16,000 hectares: new forest grew on about 192 hectares, and about 300 hectares were lost.
What is the tree count in Negara?
Negara has an estimated 104,301 trees across the 12.57 km² measured — 33.2% tree cover, 2 percentage points short of the 35% tree-cover target set for this area.
How many more trees does Negara need?
Negara needs roughly 5,655 more trees to close a 2-point shortfall against its 35% tree-cover target — about 124.4 t of extra CO₂ absorbed per year once grown.
How are Negara'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 Negara; the tree count is an estimate derived from that cover.
