Comparing satellite maps from 2000 and 2020, the forest around Lhokseumawe stayed about the same size, at about 6,010 hectares: new forest grew on about 382 hectares, and about 408 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.

At AQI 23 (Good): a good day to be active outside. Windows: open them to air the house. Masks: not needed. The reading changes through the day, so check again before a long run or ride.
What has the air quality in Lhokseumawe been like this week?
Over the last 7 days, the CAMS air-quality model put Lhokseumawe's daily AQI at 64 on average, from 51 on Nov 11 to an hourly peak of 134 on Nov 6. No day averaged above 100, the level where the air turns unhealthy for sensitive groups.
Is Lhokseumawe'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 Lhokseumawe lost since 2001?
Since 2001, the area within 10 km of Lhokseumawe has lost about 696 hectares of forest (about 980 football pitches): 15% of the forest it had in 2000. Most of it (99%) was deforestation, forest cleared for good, mainly for farms, pasture and plantations. Comparing satellite maps from 2000 and 2020, the forest around Lhokseumawe stayed about the same size, at about 6,010 hectares: new forest grew on about 382 hectares, and about 408 hectares were lost.
What is the tree count in Lhokseumawe?
Lhokseumawe has an estimated 18,924 trees across the 5.12 km² of land measured — 14.8% tree cover, 15 percentage points short of the 30% tree-cover target set for this area.
How many more trees does Lhokseumawe need?
Lhokseumawe needs roughly 19,435 more trees to close a 15-point shortfall against its 30% tree-cover target — about 427.6 t of extra CO₂ absorbed per year once grown.
How are Lhokseumawe'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 Lhokseumawe; the tree count is an estimate derived from that cover.
