Fig. 3: Tree cover by forest type and land cover.
From: More than one quarter of Africa’s tree cover is found outside areas previously classified as forest
a Distribution of mapped tree cover by land cover type and precipitation zone, with land cover classes from the Worldcover product18. See Supplementary Table 1 for mean tree cover by land cover. b Distribution of non-forest trees on African croplands, showing mean tree cover and c mean tree density on croplands. The right-side y-axis is the total cropland area, and the shaded background of the lines represent the 95% confidence interval. See Supplementary Fig. 3 for grasslands. d Reported tree cover compared to FAO statistics for ‘Forest’, defined as areas with >10% tree cover and e ‘other wooded land’ defined as areas with 5–10% tree cover, or >10% cover of trees, bushes, and shrubs. For more countries see Supplementary Fig. 4.
