Comparing satellite maps from 2000 and 2020, the forest around Badalona stayed about the same size, at about 5,790 hectares: new forest grew on about 134 hectares, and about 25 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.
