Forest gained and lost, 2000–2020
- Forest in 2000
- 17,400 acres (7,040 ha)
- Forest in 2020
- 17,300 acres (6,990 ha)
- Overall change
- −114 acres (46 ha)less forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Arlington stayed about the same size, at about 17,300 acres (6,990 hectares): new forest grew on about 603 acres (244 hectares), and about 717 acres (290 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.
