Comparing satellite maps from 2000 and 2020, the forest around Manokwari shrank from about 14,600 hectares to 13,200 hectares, a net loss of about 1,370 hectares (−9.4%). New forest grew on about 28 hectares, but 1,400 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.

The latest reading for Manokwari shows an AQI of 64 (Moderate), observed Nov 11, 01:00 local time via Open-Meteo / CAMS, US EPA index. The main pollutant is PM2.5. Unusually sensitive people should consider limiting long outdoor exertion.
Is it safe to exercise outside in Manokwari today?
At AQI 64 (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 Manokwari been like this week?
Over the last 7 days, the CAMS air-quality model put Manokwari's daily AQI at 40 on average, from 27 on Nov 7 to an hourly peak of 66 on Nov 10. No day averaged above 100, the level where the air turns unhealthy for sensitive groups.
Is Manokwari'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 Manokwari lost since 2001?
Since 2001, the area within 10 km of Manokwari has lost about 3,950 hectares of forest (about 5,500 football pitches): 27% of the forest it had in 2000. Most of it (84%) was deforestation, forest cleared for good, mainly for farms, pasture and plantations. Forest loss is slowing down: about 134 hectares a year in 2021–2025, down from 282 hectares a year in 2016–2020. Comparing satellite maps from 2000 and 2020, the forest around Manokwari shrank from about 14,600 hectares to 13,200 hectares, a net loss of about 1,370 hectares (−9.4%). New forest grew on about 28 hectares, but 1,400 hectares were lost.
What is the tree count in Manokwari?
Manokwari has an estimated 107,985 trees across the 9.35 km² of land measured — 46.2% tree cover, already past the 30% tree-cover target set for this area.
How many more trees does Manokwari need?
Manokwari has already reached its tree-cover target, so no additional trees are needed to close the gap.
How are Manokwari'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 Manokwari; the tree count is an estimate derived from that cover.
