Forest gained and lost, 2000–2020

Forest in 2000: 826 ha
Forest in 2020: 799 ha
Overall change: −27 haless forest than in 2000

Comparing satellite maps from 2000 and 2020, the forest around Nassau shrank from about 826 hectares to 799 hectares, a net loss of about 27 hectares (−3.3%). New forest grew on about 119 hectares, but 146 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 Nassau?

How many more trees does Nassau need?

Nassau has already reached its tree-cover target, so no additional trees are needed to close the gap.

How are Nassau'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 Nassau; the tree count is an estimate derived from that cover.
