Deforestation · 2001–2025
How much forest has Fuji lost?
Since 2001, the area within 10 km of Fuji has lost about 486 hectares of forest (about 680 football pitches): 9.1% of the forest it had in 2000. Most of it was lost to logging, so much of it can grow back. About 36 hectares (7.3%) was deforestation: forest cleared for good for farms, mines or towns.

Comparing satellite maps from 2000 and 2020, the forest around Fuji stayed about the same size, at about 12,200 hectares: new forest grew on about 91 hectares, and about 267 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 Fuji lost since 2001?
Since 2001, the area within 10 km of Fuji has lost about 486 hectares of forest (about 680 football pitches): 9.1% of the forest it had in 2000. Most of it was lost to logging, so much of it can grow back. About 36 hectares (7.3%) was deforestation: forest cleared for good for farms, mines or towns.

What is the tree count in Fuji?
Fuji has an estimated 139,068 trees across the 12.53 km² of land measured — 44.4% tree cover, already past the 35% tree-cover target set for this area.
How many more trees does Fuji need?
Fuji has already reached its tree-cover target, so no additional trees are needed to close the gap.
How are Fuji'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 Lu County; the tree count is an estimate derived from that cover.
