Comparing satellite maps from 2000 and 2020, the forest around Silchar stayed about the same size, at about 6,910 hectares: new forest grew on about 307 hectares, and about 348 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 Silchar
What is the air quality (AQI) in Silchar right now?
The latest reading for Silchar shows an AQI of 87 (Moderate), measured Nov 11, 22:00 local time by the Tarapur, Silchar - PCBA ground monitoring station, 300 m 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 Silchar today?
At AQI 87 (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 Silchar been like this week?
Over the last 7 days, the CAMS air-quality model put Silchar's daily AQI at 100 on average, from 68 on Nov 10 to an hourly peak of 169 on Nov 6. On 3 of those days the average was above 100, unhealthy for sensitive groups.
Is Silchar'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 Silchar lost since 2001?
Since 2001, the area within 10 km of Silchar has lost about 144 hectares of forest (about 200 football pitches): 3.5% of the forest it had in 2000. Most of it (90%) was deforestation, forest cleared for good, mainly for farms, pasture and plantations. Comparing satellite maps from 2000 and 2020, the forest around Silchar stayed about the same size, at about 6,910 hectares: new forest grew on about 307 hectares, and about 348 hectares were lost.
What is the tree count in Silchar?
Silchar has an estimated 121,969 trees across the 11.56 km² of land measured — 42.2% tree cover, already past the 30% tree-cover target set for this area.
How many more trees does Silchar need?
Silchar has already reached its tree-cover target, so no additional trees are needed to close the gap.
How are Silchar's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Gandhi Bagh, 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 Gandhi Bagh; the tree count is an estimate derived from that cover.
