How much forest has Mau lost?
There was very little forest around Mau in 2000, about 21 hectares, and about 4 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 Mau grew from about 629 hectares to 744 hectares, a net gain of about 115 hectares (+18%). New forest grew on about 125 hectares, while 10 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 Mau
What is the air quality (AQI) in Mau right now?
The latest reading for Mau shows an AQI of 174 (Unhealthy), observed Nov 10, 19:30 local time via Open-Meteo / CAMS, corrected with 20 ground-station cities within 225 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 Mau today?
At AQI 174 (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 Mau been like this week?
Over the last 7 days, the CAMS air-quality model put Mau's daily AQI at 211 on average, from 177 on Nov 4 to an hourly peak of 371 on Nov 8. On 7 of those days the average was above 100, unhealthy for sensitive groups.
Is Mau'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 Mau lost since 2001?
There was very little forest around Mau in 2000, about 21 hectares, and about 4 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 Mau grew from about 629 hectares to 744 hectares, a net gain of about 115 hectares (+18%). New forest grew on about 125 hectares, while 10 hectares were lost.
What is the tree count in Mau?
Mau has an estimated 76,425 trees across the 12.53 km² of land measured — 24.4% tree cover, 16 percentage points short of the 40% tree-cover target set for this area.
How many more trees does Mau need?
Mau needs roughly 48,862 more trees to close a 16-point shortfall against its 40% tree-cover target — about 1,075 t of extra CO₂ absorbed per year once grown.
How are Mau'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 Shaikh Damu Pura; the tree count is an estimate derived from that cover.
