Forest gained and lost, 2000–2020
- Forest in 2000
- 11,500 acres (4,670 ha)
- Forest in 2020
- 11,700 acres (4,740 ha)
- Overall change
- +195 acres (79 ha)more forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Denton stayed about the same size, at about 11,700 acres (4,740 hectares): new forest grew on about 682 acres (276 hectares), and about 484 acres (196 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.
