Comparing satellite maps from 2000 and 2020, the forest around Puchong stayed about the same size, at about 10,500 hectares: new forest grew on about 2,960 hectares, and about 3,030 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 Puchong
What is the air quality (AQI) in Puchong right now?
The latest reading for Puchong shows an AQI of 76 (Moderate), measured Nov 11, 23:00 local time by 8 ground monitoring stations via OpenAQ (the median of their readings; the nearest is Putrajaya, W.p. Putrajaya, Malaysia, 12.5 km away). The main pollutant is PM2.5. Unusually sensitive people should consider limiting long outdoor exertion.
Is it safe to exercise outside in Puchong today?
At AQI 76 (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 Puchong been like this week?
Over the last 7 days, the CAMS air-quality model put Puchong's daily AQI at 87 on average, from 81 on Nov 10 to an hourly peak of 165 on Nov 4. No day averaged above 100, the level where the air turns unhealthy for sensitive groups.
Is Puchong'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 Puchong lost since 2001?

How are Puchong's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Taman Puchong Utama, 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 Puchong Utama; the tree count is an estimate derived from that cover.
