Forest gained and lost, 2000–2020
- Forest in 2000
- 2,330 acres (944 ha)
- Forest in 2020
- 3,330 acres (1,350 ha)
- Overall change
- +996 acres (403 ha)more forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Elk Grove grew from about 2,330 acres (944 hectares) to 3,330 acres (1,350 hectares), a net gain of about 996 acres (403 hectares) (+43%). New forest grew on about 1,010 acres (407 hectares), while 11 acres (5 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.
