Comparing satellite maps from 2000 and 2020, the forest around Dijon stayed about the same size, at about 7,600 hectares: new forest grew on about 259 hectares, and about 365 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.

What is the tree count in Dijon?
Dijon has an estimated 88,061 trees across the 12.41 km² of land measured — 28.4% tree cover, 2 percentage points short of the 30% tree-cover target set for this area.
How many more trees does Dijon need?
Dijon needs roughly 4,961 more trees to close a 2-point shortfall against its 30% tree-cover target — about 109.1 t of extra CO₂ absorbed per year once grown.
How are Dijon'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 Bourroches; the tree count is an estimate derived from that cover.
