Forest gained and lost, 2000–2020
- Forest in 2000
- 44,500 acres (18,000 ha)
- Forest in 2020
- 43,500 acres (17,600 ha)
- Overall change
- −991 acres (401 ha)less forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Tyler shrank from about 44,500 acres (18,000 hectares) to 43,500 acres (17,600 hectares), a net loss of about 991 acres (401 hectares) (−2.2%). New forest grew on about 2,490 acres (1,010 hectares), but 3,480 acres (1,410 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.
