Comparing satellite maps from 2000 and 2020, the forest around Seremban shrank from about 22,000 hectares to 20,700 hectares, a net loss of about 1,390 hectares (−6.3%). New forest grew on about 2,140 hectares, but 3,530 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 Seremban
What is the air quality (AQI) in Seremban right now?
The latest reading for Seremban shows an AQI of 52 (Moderate), measured Nov 12, 00:00 local time by the Seremban, Negeri Sembilan, Malaysia ground monitoring station, 3.4 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 Seremban today?
At AQI 52 (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 Seremban been like this week?
Over the last 7 days, the CAMS air-quality model put Seremban's daily AQI at 39 on average, from 24 on Nov 7 to an hourly peak of 79 on Nov 5. No day averaged above 100, the level where the air turns unhealthy for sensitive groups.
Is Seremban'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 Seremban lost since 2001?
Since 2001, the area within 10 km of Seremban has lost about 8,940 hectares of forest (about 13,000 football pitches): 48% of the forest it had in 2000.
