Comparing satellite maps from 2000 and 2020, the forest around Mohali grew from about 464 hectares to 633 hectares, a net gain of about 169 hectares (+36%). New forest grew on about 197 hectares, while 29 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 Mohali
What is the air quality (AQI) in Mohali right now?
The latest reading for Mohali shows an AQI of 151 (Unhealthy), measured Nov 11, 21:00 local time by 3 ground monitoring stations via OpenAQ (the median of their readings; the nearest is Sector-53, Chandigarh - CPCC, 4.7 km away). The main pollutant is PM2.5. Everyone should limit long outdoor exertion; sensitive groups more so.
Is it safe to exercise outside in Mohali today?
At AQI 151 (Unhealthy): everyone should cut down long or hard exercise; sensitive groups should avoid it. Windows: keep them closed. Masks: wear an N95 outdoors. The reading changes through the day, so check again before a long run or ride.
What has the air quality in Mohali been like this week?
Over the last 7 days, the CAMS air-quality model put Mohali's daily AQI at 127 on average, from 102 on Nov 7 to an hourly peak of 186 on Nov 9. On 7 of those days the average was above 100, unhealthy for sensitive groups.
Is Mohali'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 Mohali lost since 2001?
Since 2001, the area within 10 km of Mohali has lost about 12 hectares of forest (about 17 football pitches): 2.4% of the forest it had in 2000. Most of it (70%) was deforestation, forest cleared for good, mainly for towns and roads. Comparing satellite maps from 2000 and 2020, the forest around Mohali grew from about 464 hectares to 633 hectares, a net gain of about 169 hectares (+36%). New forest grew on about 197 hectares, while 29 hectares were lost.
What is the tree count in Mohali?
Mohali has an estimated 78,540 trees across the 12.57 km² measured — 25.0% tree cover, 15 percentage points short of the 40% tree-cover target set for this area.
How many more trees does Mohali need?
Mohali needs roughly 47,124 more trees to close a 15-point shortfall against its 40% tree-cover target — about 1,037 t of extra CO₂ absorbed per year once grown.
How are Mohali's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Sector 68, 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 Sector 68; the tree count is an estimate derived from that cover.
