- −1,330 haless forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Bercham shrank from about 18,700 hectares to 17,400 hectares, a net loss of about 1,330 hectares (−7.1%). New forest grew on about 1,030 hectares, but 2,360 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 Bercham
What is the air quality (AQI) in Bercham right now?
The latest reading for Bercham shows an AQI of 68 (Moderate), measured Nov 12, 01:00 local time by the Ipoh ground monitoring station, 4.3 km away, via OpenAQ. The main pollutant is PM2.5. Unusually sensitive people should consider limiting long outdoor exertion.
Is it safe to exercise outside in Bercham 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 Bercham been like this week?
Over the last 7 days, the CAMS air-quality model put Bercham's daily AQI at 37 on average, from 25 on Nov 5 to an hourly peak of 77 on Nov 7. No day averaged above 100, the level where the air turns unhealthy for sensitive groups.
Is Bercham'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 Bercham lost since 2001?
Since 2001, the area within 10 km of Bercham has lost about 5,000 hectares of forest (about 7,000 football pitches): 32% of the forest it had in 2000.

What is the tree count in Bercham?
Bercham has an estimated 71,485 trees across the 12.54 km² of land measured — 22.8% tree cover, 7 percentage points short of the 30% tree-cover target set for this area.
How many more trees does Bercham need?
Bercham needs roughly 22,574 more trees to close a 7-point shortfall against its 30% tree-cover target — about 496.6 t of extra CO₂ absorbed per year once grown.
How are Bercham's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Ipoh, 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 Ipoh; the tree count is an estimate derived from that cover.
