Causes for 2025 are estimates, based on what caused forest loss in the same places up to 2024.
Forest gained and lost, 2000–2020
- Forest in 2000
- 2,660 acres (1,080 ha)
- Forest in 2020
- 3,260 acres (1,320 ha)
- Overall change
- +598 acres (242 ha)more forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around West Valley City grew from about 2,660 acres (1,080 hectares) to 3,260 acres (1,320 hectares), a net gain of about 598 acres (242 hectares) (+22%). New forest grew on about 608 acres (246 hectares), while 10 acres (4 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.
