Forest gained and lost, 2000–2020

- Overall change
- +225 acres (91 ha)more forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Spokane stayed about the same size, at about 31,900 acres (12,900 hectares): new forest grew on about 1,140 acres (461 hectares), and about 917 acres (371 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.

How many more trees does Spokane need?
Spokane needs roughly 10,930 more trees to close a 3-point shortfall against its 30% tree-cover target — about 240.5 t of extra CO₂ absorbed per year once grown.
How are Spokane's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Spokane, 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 Spokane; the tree count is an estimate derived from that cover.
