Comparing satellite maps from 2000 and 2020, the forest around Thiruvananthapuram stayed about the same size, at about 16,900 hectares: new forest grew on about 65 hectares, and about 399 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 Thiruvananthapuram
What is the air quality (AQI) in Thiruvananthapuram right now?
The latest reading for Thiruvananthapuram shows an AQI of 92 (Moderate), measured Nov 11, 17:45 local time by the Plammoodu, Thiruvananthapuram - Kerala PCB ground monitoring station, 3.3 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 Thiruvananthapuram today?
At AQI 92 (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 Thiruvananthapuram been like this week?
Over the last 7 days, the CAMS air-quality model put Thiruvananthapuram's daily AQI at 58 on average, from 44 on Nov 7 to an hourly peak of 90 on Nov 4. No day averaged above 100, the level where the air turns unhealthy for sensitive groups.
Is Thiruvananthapuram's AQI the same as India's AQI (CPCB)?
No. Airleaf shows the US EPA Air Quality Index (AQI), the scale used by IQAir and most air-quality apps. India's Central Pollution Control Board (CPCB) publishes the National Air Quality Index on its own scale: 0–50 good, 51–100 satisfactory, 101–200 moderate, 201–300 poor, 301–400 very poor and 401–500 severe. The two scales don't line up. At moderate fine-particle levels the US scale reads higher: 55 µg/m³ of PM2.5 is 149 on the US AQI but about 92, "satisfactory", on India's. In heavy smog India's reads higher: 100 µg/m³ is 182 on the US AQI and about 232, "poor", on India's. CPCB also averages particles over 24 hours, so its figure moves more slowly than an hourly reading.
How much forest has the area around Thiruvananthapuram lost since 2001?
Since 2001, the area within 10 km of Thiruvananthapuram has lost about 384 hectares of forest (about 540 football pitches): 4.7% of the forest it had in 2000. Most of it (97%) was deforestation, forest cleared for good, mainly for towns and roads. Comparing satellite maps from 2000 and 2020, the forest around Thiruvananthapuram stayed about the same size, at about 16,900 hectares: new forest grew on about 65 hectares, and about 399 hectares were lost.
What is the tree count in Thiruvananthapuram?
Thiruvananthapuram has an estimated 105,138 trees across the 12.56 km² of land measured — 33.5% tree cover, already past the 30% tree-cover target set for this area.
How many more trees does Thiruvananthapuram need?
Thiruvananthapuram has already reached its tree-cover target, so no additional trees are needed to close the gap.
How are Thiruvananthapuram's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near East Fort, 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 East Fort; the tree count is an estimate derived from that cover.
