Overall change

Comparing satellite maps from 2000 and 2020, the forest around Kuala Krai shrank from about 28,000 hectares to 27,000 hectares, a net loss of about 926 hectares (−3.3%). New forest grew on about 1,270 hectares, but 2,190 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 Kuala Krai

What is the air quality (AQI) in Kuala Krai right now?

The latest reading for Kuala Krai shows an AQI of 15 (Good), observed Nov 10, 20:00 local time via Open-Meteo / CAMS, corrected with 13 ground-station cities within 245 km, US EPA index. The main pollutant is PM2.5. Air quality is satisfactory for everyone.

Is it safe to exercise outside in Kuala Krai today?

At AQI 15 (Good): a good day to be active outside. Windows: open them to air the house. Masks: not needed. The reading changes through the day, so check again before a long run or ride.

What has the air quality in Kuala Krai been like this week?

Over the last 7 days, the CAMS air-quality model put Kuala Krai's daily AQI at 20 on average, from 11 on Nov 9 to an hourly peak of 47 on Nov 4. No day averaged above 100, the level where the air turns unhealthy for sensitive groups.

Is Kuala Krai'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 Kuala Krai lost since 2001?

Since 2001, the area within 10 km of Kuala Krai has lost about 12,400 hectares of forest (about 17,000 football pitches): 46% of the forest it had in 2000. Most of it (92%) was deforestation, forest cleared for good, mainly for farms, pasture and plantations. Forest loss is speeding up: about 617 hectares a year in 2021–2025, up from 443 hectares a year in 2016–2020. Comparing satellite maps from 2000 and 2020, the forest around Kuala Krai shrank from about 28,000 hectares to 27,000 hectares, a net loss of about 926 hectares (−3.3%). New forest grew on about 1,270 hectares, but 2,190 hectares were lost.

What is the tree count in Kuala Krai?

Kuala Krai has an estimated 203,191 trees across the 11.77 km² of land measured — 69.1% tree cover, already past the 30% tree-cover target set for this area.

How many more trees does Kuala Krai need?

Kuala Krai has already reached its tree-cover target, so no additional trees are needed to close the gap.

How are Kuala Krai'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 Kuala Krai; the tree count is an estimate derived from that cover.
