Comparing satellite maps from 2000 and 2020, the forest around Teluk Intan shrank from about 18,800 hectares to 17,900 hectares, a net loss of about 892 hectares (−4.7%). New forest grew on about 1,620 hectares, but 2,510 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 Teluk Intan
What is the air quality (AQI) in Teluk Intan right now?
The latest reading for Teluk Intan shows an AQI of 59 (Moderate), observed Nov 10, 23:00 local time via Open-Meteo / CAMS, corrected with 16 ground-station cities within 145 km, 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 Teluk Intan today?
At AQI 59 (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 Teluk Intan been like this week?
Over the last 7 days, the CAMS air-quality model put Teluk Intan's daily AQI at 51 on average, from 42 on Nov 5 to an hourly peak of 81 on Nov 4. No day averaged above 100, the level where the air turns unhealthy for sensitive groups.
Is Teluk Intan'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 Teluk Intan lost since 2001?
Since 2001, the area within 10 km of Teluk Intan has lost about 9,980 hectares of forest (about 14,000 football pitches): 57% of the forest it had in 2000.

What is the tree count in Teluk Intan?
Teluk Intan has an estimated 97,407 trees across the 9.82 km² of land measured — 39.7% tree cover, already past the 30% tree-cover target set for this area.
How many more trees does Teluk Intan need?
Teluk Intan has already reached its tree-cover target, so no additional trees are needed to close the gap.
How are Teluk Intan'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 Pekan Teluk Intan; the tree count is an estimate derived from that cover.
