Forest gained and lost, 2000–2020

- 8,890 acres (3,600 ha)
- Forest in 2020

Comparing satellite maps from 2000 and 2020, the forest around Hialeah grew from about 8,890 acres (3,600 hectares) to 9,820 acres (3,980 hectares), a net gain of about 937 acres (379 hectares) (+11%). New forest grew on about 1,340 acres (544 hectares), while 408 acres (165 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.
