Deforestation · 2001–2025
How much forest has Shimla lost?
Since 2001, the area within 10 km of Shimla has lost about 80 hectares of forest (about 110 football pitches): under 1% of the forest it had in 2000. The biggest cause was logging (32%), after which forest can grow back. About 25 hectares (31%) was deforestation: forest cleared for good for farms, mines or towns.

Comparing satellite maps from 2000 and 2020, the forest around Shimla grew from about 22,000 hectares to 22,500 hectares, a net gain of about 496 hectares (+2.3%). New forest grew on about 546 hectares, while 50 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 Shimla
What is the air quality (AQI) in Shimla right now?
The latest reading for Shimla shows an AQI of 152 (Unhealthy), observed Nov 11, 02:30 local time via Open-Meteo / CAMS, corrected with 2 ground-station cities within 65 km, US EPA index. The main pollutant is PM2.5. Everyone should limit long outdoor exertion; sensitive groups more so.
Is it safe to exercise outside in Shimla today?
At AQI 152 (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 Shimla been like this week?
Over the last 7 days, the CAMS air-quality model put Shimla's daily AQI at 83 on average, from 64 on Nov 5 to an hourly peak of 128 on Nov 11. On 1 of those days the average was above 100, unhealthy for sensitive groups.
Is Shimla'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 Shimla lost since 2001?
Since 2001, the area within 10 km of Shimla has lost about 80 hectares of forest (about 110 football pitches): under 1% of the forest it had in 2000. The biggest cause was logging (32%), after which forest can grow back. About 25 hectares (31%) was deforestation: forest cleared for good for farms, mines or towns. Comparing satellite maps from 2000 and 2020, the forest around Shimla grew from about 22,000 hectares to 22,500 hectares, a net gain of about 496 hectares (+2.3%). New forest grew on about 546 hectares, while 50 hectares were lost.
What is the tree count in Shimla?
Shimla has an estimated 242,217 trees across the 12.57 km² measured — 77.1% tree cover, already past the 40% tree-cover target set for this area.
How many more trees does Shimla need?
Shimla has already reached its tree-cover target, so no additional trees are needed to close the gap.
How are Shimla'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 Shilli; the tree count is an estimate derived from that cover.
