  1. The second column shows specific combinations of hotspot criteria: total species richness (T), endemic species richness (E), threatened species richness (Th), and rare species richness (R). For example, the criterion 'T-E’ means that the grid cells fulfilled the total and endemic hotspot criterion but not the threatened or rare hotspot criteria. The third column gives the number of grid cells fulfilling the criteria combination given in the second column. The fourth column is the percentage in relation to all hotspot grid cells (a total of 2,942 grid cells which fulfilled at least one hotspot criterion). The fifth column gives the number of grid cells (and percentage) fulfilling the hotspot criteria (or criterion) given in the first column.
