How much forest has Kelo lost?
There was almost no forest around Kelo in 2000, so there has been almost nothing to lose since. Only fairly dense woodland counts as forest in these maps, so scattered street and garden trees don't show up here.

Forest gained and lost, 2000–2020
- Forest in 2000
- 278 ha
- Forest in 2020
- 391 ha
- Overall change
- +113 hamore forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Kelo grew from about 278 hectares to 391 hectares, a net gain of about 113 hectares (+41%). New forest grew on about 143 hectares, while 30 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 much forest has the area around Kelo lost since 2001?

What is the tree count in Kelo?
Kelo has an estimated 65,031 trees across the 12.57 km² measured — 20.7% tree cover, 9 percentage points short of the 30% tree-cover target set for this area.
How many more trees does Kelo need?
Kelo needs roughly 29,217 more trees to close a 9-point shortfall against its 30% tree-cover target — about 642.8 t of extra CO₂ absorbed per year once grown.
How are Kelo's air quality and tree cover measured?
Air quality comes from ground monitoring stations via OpenAQ where one reports nearby, and otherwise, as here, from the Open-Meteo / CAMS model, which may differ from street-level monitors. Tree cover is measured from Sentinel-2 L2A (ESA Copernicus) via Earth Search satellite imagery at 10 m detail across a 2 km radius around Kelo; the tree count is an estimate derived from that cover.
