Forest gained and lost, 2000–2020

- 43,200 acres (17,500 ha)
- Forest in 2020

- Overall change
- +381 acres (154 ha)more forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Edison stayed about the same size, at about 43,600 acres (17,600 hectares): new forest grew on about 1,160 acres (469 hectares), and about 778 acres (315 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.
