Comparing satellite maps from 2000 and 2020, the forest around Ulan Bator stayed about the same size, at about 4,100 hectares: new forest grew on about 110 hectares, and about 94 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.

Can I see satellite images of Ulan Bator over the years?

Yes. The timelapse at the top of this page has a satellite photo for every year from 2017 to 2026 of a 5 × 5 km area in the centre of Ulan Bator. Press play to watch it change, or turn on "Show cleared forest" to see exactly where trees were lost.

How is forest loss measured?

We use satellite maps from the University of Maryland (Hansen and colleagues) that show, for every 30 × 30 m patch of land on Earth, the year its trees were cut down, burned or died, from 2001 to 2025. We add up those patches within 10 km of the centre of Ulan Bator, counting only places that were at least 30% covered by trees in 2000. The cause of each loss comes from a map made by the World Resources Institute and Google DeepMind. All figures are estimates.
