Deforestation · 2001–2025
How much forest has Salzburg lost?
Since 2001, the area within 10 km of Salzburg has lost about 1,160 hectares of forest (about 1,600 football pitches): 7.4% of the forest it had in 2000. Most of it was lost to logging, so much of it can grow back. About 105 hectares (9.1%) was deforestation: forest cleared for good for farms, mines or towns.

Comparing satellite maps from 2000 and 2020, the forest around Salzburg stayed about the same size, at about 15,500 hectares: new forest grew on about 151 hectares, and about 318 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.
