Comparing satellite maps from 2000 and 2020, the forest around Rivera grew from about 8,830 hectares to 9,510 hectares, a net gain of about 676 hectares (+7.7%). New forest grew on about 1,160 hectares, while 483 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 Rivera need?
Rivera has already reached its tree-cover target, so no additional trees are needed to close the gap.
How are Rivera'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 Lavalleja; the tree count is an estimate derived from that cover.
