Comparing satellite maps from 2000 and 2020, the forest around Chirmiri grew from about 6,780 hectares to 7,050 hectares, a net gain of about 272 hectares (+4%). New forest grew on about 311 hectares, while 40 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.

Questions about Chirmiri
What is the air quality (AQI) in Chirmiri right now?
The latest reading for Chirmiri shows an AQI of 115 (Unhealthy for sensitive groups), observed Nov 10, 18:30 local time via Open-Meteo / CAMS, corrected with 2 ground-station cities within 185 km, US EPA index. The main pollutant is PM2.5. Sensitive groups should limit long or intense outdoor activity.
Is it safe to exercise outside in Chirmiri today?
At AQI 115 (Unhealthy for sensitive groups): children, older adults and people with asthma or heart disease should cut down long or hard exercise. Windows: close them to keep the outside air out. Masks: sensitive groups: an N95 outdoors. The reading changes through the day, so check again before a long run or ride.
What has the air quality in Chirmiri been like this week?
Over the last 7 days, the CAMS air-quality model put Chirmiri's daily AQI at 137 on average, from 98 on Nov 4 to an hourly peak of 176 on Nov 10. On 6 of those days the average was above 100, unhealthy for sensitive groups.
Is Chirmiri'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 Chirmiri lost since 2001?
Since 2001, the area within 10 km of Chirmiri has lost about 12 hectares of forest (about 17 football pitches): under 1% of the forest it had in 2000. Most of it (91%) was deforestation, forest cleared for good, mainly for farms, pasture and plantations. Comparing satellite maps from 2000 and 2020, the forest around Chirmiri grew from about 6,780 hectares to 7,050 hectares, a net gain of about 272 hectares (+4%). New forest grew on about 311 hectares, while 40 hectares were lost.
What is the tree count in Chirmiri?
Chirmiri has an estimated 208,602 trees across the 12.57 km² measured — 66.4% tree cover, already past the 35% tree-cover target set for this area.
How many more trees does Chirmiri need?
Chirmiri has already reached its tree-cover target, so no additional trees are needed to close the gap.
How are Chirmiri'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 Chirimiri; the tree count is an estimate derived from that cover.
