- Overall change
- −3,880 haless forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Kapar shrank from about 19,700 hectares to 15,800 hectares, a net loss of about 3,880 hectares (−20%). New forest grew on about 868 hectares, but 4,750 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 Kapar
What is the air quality (AQI) in Kapar right now?
The latest reading for Kapar shows an AQI of 68 (Moderate), measured Nov 11, 23:00 local time by 3 ground monitoring stations via OpenAQ (the median of their readings; the nearest is Pelabuhan Kelang, Selangor, Malaysia, 13.6 km away). The main pollutant is PM2.5. Unusually sensitive people should consider limiting long outdoor exertion.
Is it safe to exercise outside in Kapar today?
At AQI 68 (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 Kapar been like this week?
Over the last 7 days, the CAMS air-quality model put Kapar's daily AQI at 51 on average, from 31 on Nov 11 to an hourly peak of 77 on Nov 5. No day averaged above 100, the level where the air turns unhealthy for sensitive groups.
Is Kapar's AQI the same as Malaysia's API (IPU)?
No. Airleaf shows the US EPA Air Quality Index (AQI), the scale used by IQAir and most air-quality apps. Malaysia's Department of Environment (Jabatan Alam Sekitar) publishes its own Air Pollutant Index, the API or Indeks Pencemar Udara (IPU), every hour for each of its monitoring stations on APIMS (apims.doe.gov.my). Both scales call 0–50 good and 51–100 moderate; above that the IPU runs 101–200 unhealthy, 201–300 very unhealthy and over 300 hazardous. The two use different breakpoints and averaging times, so the numbers for the same hour often differ. For the official IPU reading, check the nearest station on APIMS.
How much forest has the area around Kapar lost since 2001?
Since 2001, the area within 10 km of Kapar has lost about 9,700 hectares of forest (about 14,000 football pitches): 53% of the forest it had in 2000.

Forest loss is slowing down: about 264 hectares a year in 2021–2025, down from 366 hectares a year in 2016–2020. Comparing satellite maps from 2000 and 2020, the forest around Kapar shrank from about 19,700 hectares to 15,800 hectares, a net loss of about 3,880 hectares (−20%). New forest grew on about 868 hectares, but 4,750 hectares were lost.
What is the tree count in Kapar?
Kapar has an estimated 171,217 trees across the 12.57 km² measured — 54.5% tree cover, already past the 30% tree-cover target set for this area.
How many more trees does Kapar need?
Kapar has already reached its tree-cover target, so no additional trees are needed to close the gap.
How are Kapar's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Taman Intan, via OpenAQ; the 7-day trend is the Open-Meteo / CAMS model's estimate. 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 Taman Intan; the tree count is an estimate derived from that cover.
