How much forest has Wuhan lost?
There was almost no forest around Wuhan in 2000, so there has been almost nothing to lose 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 June 2017 of a 5 × 5 km area in the city center.
Forest gained and lost, 2000–2020
- Forest in 2000
- 499 ha
- Forest in 2020
- 1,100 ha
- Overall change
- +604 hamore forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Wuhan grew from about 499 hectares to 1,100 hectares, a net gain of about 604 hectares (+121%). New forest grew on about 606 hectares, while 3 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.

The main pollutant is PM2.5. Sensitive groups should limit long or intense outdoor activity.
Is it safe to exercise outside in Wuhan today?
At AQI 107 (Unhealthy for sensitive groups): children, older adults and people with asthma or heart disease should cut down long or hard exercise. Windows: close them to keep the outside air out. Masks: sensitive groups: an N95 outdoors. The reading changes through the day, so check again before a long run or ride.

How many more trees does Wuhan need?
Wuhan needs roughly 61,893 more trees to close a 20-point shortfall against its 35% tree-cover target — about 1,362 t of extra CO₂ absorbed per year once grown.
How are Wuhan's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Jianghan District, 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 Jianghan District; the tree count is an estimate derived from that cover.
