There was very little forest around Long Beach in 2000, about 169 acres (68 hectares), and about 12 acres (5 hectares) of it has been lost since. Only fairly dense woodland counts as forest in these maps, so scattered street and garden trees don't show up here.

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
- 660 acres (267 ha)
- Forest in 2020
- 689 acres (279 ha)
- Overall change
- +30 acres (12 ha)more forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Long Beach grew from about 660 acres (267 hectares) to 689 acres (279 hectares), a net gain of about 30 acres (12 hectares) (+4.5%). New forest grew on about 43 acres (17 hectares), while 14 acres (6 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.
