FIGURE 1.

Relative environmental (top), geographical (centre) and structural (bottom) dissimilarities (%) over global forested areas with respect to conditions covered by potential forest biomass reference measurement sites (n = 195, top and centre; n = 118, bottom). Blank continental areas and hollow points (bottom), respectively, correspond to forested areas and sites not sampled (yet, for those within ±51.6° latitude) by GEDI. Relative dissimilarity was categorized for display purposes. Non‐forested areas are in grey. The map projection is EASE‐Grid 2.0 (epsg:6933), a global, equal‐area protection and spatial resolution is 5 km. Map lines delineate study areas and do not necessarily depict accepted national boundaries.
