Forest gained and lost, 2000–2020

- 37,600 acres (15,200 ha)
- Forest in 2020
- 37,600 acres (15,200 ha)
- Overall change
- −5 acres (2 ha)less forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Nashville stayed about the same size, at about 37,600 acres (15,200 hectares): new forest grew on about 1,370 acres (554 hectares), and about 1,370 acres (556 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.
