How much forest has Hisar lost?
There was very little forest around Hisar in 2000, about 16 hectares, and about 2 hectares of it has been lost since. Only fairly dense woodland counts as forest in these maps, so scattered street and garden trees don't show up here.
2017: satellite photo from February 2017 of a 5 × 5 km area in the city center.
The worst year was 2006, when about 1 hectare of forest were lost.

Comparing satellite maps from 2000 and 2020, the forest around Hisar grew from about 111 hectares to 138 hectares, a net gain of about 27 hectares (+24%). New forest grew on about 37 hectares, while 9 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 Hisar
What is the air quality (AQI) in Hisar right now?
The latest reading for Hisar shows an AQI of 474 (Hazardous), measured Nov 11, 20:00 local time by the Urban Estate-II, Hisar - HSPCB ground monitoring station, 2.6 km away, via OpenAQ. The main pollutant is PM2.5. Emergency conditions — avoid outdoor activity.
Is it safe to exercise outside in Hisar today?
At AQI 474 (Hazardous): everyone should avoid all outdoor exertion. Windows: keep them closed and seal gaps. Masks: wear an N95 if you must go out. The reading changes through the day, so check again before a long run or ride.
What has the air quality in Hisar been like this week?
Over the last 7 days, the CAMS air-quality model put Hisar's daily AQI at 211 on average, from 166 on Nov 7 to an hourly peak of 293 on Nov 5. On 7 of those days the average was above 100, unhealthy for sensitive groups.
Is Hisar'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 Hisar lost since 2001?
There was very little forest around Hisar in 2000, about 16 hectares, and about 2 hectares of it has been lost since. Only fairly dense woodland counts as forest in these maps, so scattered street and garden trees don't show up here. Comparing satellite maps from 2000 and 2020, the forest around Hisar grew from about 111 hectares to 138 hectares, a net gain of about 27 hectares (+24%). New forest grew on about 37 hectares, while 9 hectares were lost.
What is the tree count in Hisar?
Hisar has an estimated 74,456 trees across the 12.57 km² measured — 23.7% tree cover, 21 percentage points short of the 45% tree-cover target set for this area.
How many more trees does Hisar need?
Hisar needs roughly 66,916 more trees to close a 21-point shortfall against its 45% tree-cover target — about 1,472 t of extra CO₂ absorbed per year once grown.
How are Hisar's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Rampura Mohalla, 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 Rampura Mohalla; the tree count is an estimate derived from that cover.
