Comparing satellite maps from 2000 and 2020, the forest around Stockholm shrank from about 10,400 hectares to 9,480 hectares, a net loss of about 875 hectares (−8.4%). New forest grew on about 83 hectares, but 957 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 Stockholm?
Stockholm has an estimated 56,729 trees across the 9.74 km² of land measured — 23.3% tree cover, 7 percentage points short of the 30% tree-cover target set for this area.
How many more trees does Stockholm need?
Stockholm needs roughly 16,313 more trees to close a 7-point shortfall against its 30% tree-cover target — about 358.9 t of extra CO₂ absorbed per year once grown.
How are Stockholm's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Norrmalm, 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 Norrmalm; the tree count is an estimate derived from that cover.
