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
- 8,070 acres (3,270 ha)
- Forest in 2020
- 8,990 acres (3,640 ha)
- Overall change
- +919 acres (372 ha)more forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Miami grew from about 8,070 acres (3,270 hectares) to 8,990 acres (3,640 hectares), a net gain of about 919 acres (372 hectares) (+11%). New forest grew on about 981 acres (397 hectares), while 62 acres (25 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.
