Comparing satellite maps from 2000 and 2020, the forest around Odense grew from about 2,080 hectares to 2,540 hectares, a net gain of about 455 hectares (+22%). New forest grew on about 580 hectares, while 125 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.

How much forest has the area around Odense lost since 2001?
Since 2001, the area within 10 km of Odense has lost about 92 hectares of forest (about 130 football pitches): 3.2% of the forest it had in 2000.

Comparing satellite maps from 2000 and 2020, the forest around Odense grew from about 2,080 hectares to 2,540 hectares, a net gain of about 455 hectares (+22%). New forest grew on about 580 hectares, while 125 hectares were lost.
What is the tree count in Odense?
Odense has an estimated 100,047 trees across the 12.43 km² of land measured — 32.2% tree cover, already past the 30% tree-cover target set for this area.
How many more trees does Odense need?
Odense has already reached its tree-cover target, so no additional trees are needed to close the gap.
How are Odense'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 Odense C; the tree count is an estimate derived from that cover.
