Forest gained and lost, 2000–2020
- Forest in 2000
- 2,740 acres (1,110 ha)
- Forest in 2020
- 2,480 acres (1,010 ha)
- Overall change
- −259 acres (105 ha)less forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Clovis shrank from about 2,740 acres (1,110 hectares) to 2,480 acres (1,010 hectares), a net loss of about 259 acres (105 hectares) (−9.5%). New forest grew on about 336 acres (136 hectares), but 593 acres (240 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.

What is the tree count in Clovis?
Clovis has an estimated 34,454 trees across the 4.8 sq mi (12.53 km²) of land measured — 11.0% tree cover, 19 percentage points short of the 30% tree-cover target set for this area.
How many more trees does Clovis need?
Clovis needs roughly 59,511 more trees to close a 19-point shortfall against its 30% tree-cover target — about 1,309 t of extra CO₂ absorbed per year once grown.
How are Clovis's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Old Town Clovis, via OpenAQ; the 7-day trend is the Open-Meteo / CAMS model's estimate. Tree cover is measured from Sentinel-2 L2A (ESA Copernicus) via Earth Search satellite imagery at 10 m detail across a 1.2 mi (2 km) radius around Old Town Clovis; the tree count is an estimate derived from that cover.
