Deforestation · 2001–2025
Since 2001, the U.S. Virgin Islands has lost about 4,610 acres (1,870 hectares) of forest (about 3,500 football fields): 11% of the forest it had in 2000. The biggest cause was shifting farming (31%), after which forest can grow back. About 2,270 acres (918 hectares) (49%) was deforestation: forest cleared for good for farms, mines or towns.

Forest loss is slowing down: about 65 acres (26 hectares) a year in 2021–2025, down from 563 acres (228 hectares) a year in 2016–2020. The worst year was 2017, when about 2,600 acres (1,050 hectares) of forest were lost.
Also: storms, floods and other natural causes, unknown causes.
Causes for 2025 are estimates, based on what caused forest loss in the same places up to 2024.

58.9% of the U.S. Virgin Islands was forested as of 2024, against a 30% benchmark. That already clears the benchmark — the city reports above show where cover is still thin locally. Source: World Bank (FAO).

Clean-air buying guides
Picked by tested clean-air delivery rate (CADR), noise and running cost, from independent test labels. No brand pays to be listed.
Air purifiers that keep up with wildfire smoke and winter smog, ranked by verified smoke CADR, with the room each one clears on a smoky day.
Good HEPA air purifiers under $200 at the makers' own prices, compared on verified clean air, room size and what the filters cost each year.
NIOSH-approved N95 masks and P100 respirators for smog and smoke, and how to get the fit right. Cloth and surgical masks do little against PM2.5.
Frequently asked
Airleaf measures 2 cities in the U.S. Virgin Islands. Charlotte Amalie reads AQI 48, Saint Croix reads AQI 106 right now.
About 4,610 acres (1,870 ha) from 2001 to 2025, 11% of the forest it had in 2000, from the University of Maryland's yearly satellite maps of forest loss. 2,270 acres (918 ha) of it was cleared for good, for farms, mines or towns.
Each city's reading is the US EPA air quality index, from ground monitoring stations where one has reported recently nearby, and from the CAMS atmospheric model elsewhere; each city's report says which. Tree cover is measured over the same 1.2 mi (2 km) radius in every city, so the cities compare like for like.
