Overall change
+376 acres (152 ha)more forest than in 2000

Comparing satellite maps from 2000 and 2020, the forest around Provo grew from about 14,400 acres (5,810 hectares) to 14,700 acres (5,960 hectares), a net gain of about 376 acres (152 hectares) (+2.6%). New forest grew on about 610 acres (247 hectares), while 234 acres (95 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.
