How much forest has Pueblo lost?
There was very little forest around Pueblo in 2000, about 186 acres (75 hectares), and about 10 acres (4 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.
2018: satellite photo from August 2018 of a 5 × 5 km area in the city center.
The worst year was 2004, when about 5 acres (2 hectares) of forest were lost.

Forest gained and lost, 2000–2020
- Forest in 2000
- 1,170 acres (474 ha)
- Forest in 2020

- Overall change
- +282 acres (114 ha)more forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Pueblo grew from about 1,170 acres (474 hectares) to 1,450 acres (588 hectares), a net gain of about 282 acres (114 hectares) (+24%). New forest grew on about 299 acres (121 hectares), while 16 acres (7 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.
