The number of tree species and individuals per continent in the Global Forest Biodiversity Initiative (GFBI) database. This dataset (blue points in the central map) was used for the parametric estimation and merged with the TREECHANGE occurrence-based data (purple points in the central map) to provide the estimates in this study. Green areas represent the global tree cover. GFBI consists of abundance-based records of 38 million trees for 28,192 species. Depicted here are some of the most frequent species recorded in each continent. Some GFBI and TREECHANGE points may overlap in the map. Image credit: Gatti et al., doi: 10.1073/pnas.2115329119.
