Global Forest Extent for Global Ecological Zones

Sources: Global Ecological Zones (FAO, 2012); Pre-agricultural era extent (Billington et al., 1997; Current extent canopy cover (Hansen et al., 2013); Canopy height (Lang et al., 2022); Structural classes (Carnahan, 1977; Specht, 1970); Primary forest proxy at global scale using Intact Forest Landscapes in temperate and boreal zones (Potopov et al., 2017) and hinterland forest in tropical and subtropical zones (Tyukavina et al., 2016) (this does not include small areas of primary forest). Areas of forest lost have been masked out up until 2021 (Hansen et al. 2013).
