Comparing satellite maps from 2000 and 2020, the forest around Mukim Pulai shrank from about 17,200 hectares to 11,700 hectares, a net loss of about 5,470 hectares (−32%). New forest grew on about 1,380 hectares, but 6,850 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 Mukim Pulai

What is the air quality (AQI) in Mukim Pulai right now?

The latest reading for Mukim Pulai shows an AQI of 77 (Moderate), measured Nov 12, 00:00 local time by the Larkin Lama, Johor, Malaysia ground monitoring station, 8.8 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 Mukim Pulai today?

At AQI 77 (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 Mukim Pulai been like this week?

Over the last 7 days, the CAMS air-quality model put Mukim Pulai's daily AQI at 60 on average, from 45 on Nov 10 to an hourly peak of 118 on Nov 6. No day averaged above 100, the level where the air turns unhealthy for sensitive groups.

Is Mukim Pulai'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 Mukim Pulai lost since 2001?

Since 2001, the area within 10 km of Mukim Pulai has lost about 8,510 hectares of forest (about 12,000 football pitches): 57% of the forest it had in 2000.

How many more trees does Mukim Pulai need?

How are Mukim Pulai's air quality and tree cover measured?

Air quality is measured by ground monitoring stations near Skudai, 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 Skudai; the tree count is an estimate derived from that cover.
