Forest gained and lost, 2000–2020
- Forest in 2000
- 20,100 acres (8,140 ha)
- Forest in 2020
- 18,800 acres (7,620 ha)
- Overall change
- −1,270 acres (515 ha)less forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around League City shrank from about 20,100 acres (8,140 hectares) to 18,800 acres (7,620 hectares), a net loss of about 1,270 acres (515 hectares) (−6.3%). New forest grew on about 1,640 acres (663 hectares), but 2,910 acres (1,180 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.
