Forest gained and lost, 2000–2020

- 10,600 acres (4,280 ha)
- Forest in 2020
- 10,200 acres (4,140 ha)
- Overall change
- −331 acres (134 ha)less forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Killeen shrank from about 10,600 acres (4,280 hectares) to 10,200 acres (4,140 hectares), a net loss of about 331 acres (134 hectares) (−3.1%). New forest grew on about 373 acres (151 hectares), but 707 acres (286 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.
