Table 3 Current suitable area and predicted area (as percentage of current area) for each phylogroups of Senegalia senegal and their co-occurrence for the three climate change scenarios RCP 4.5, RCP 6.0 and RCP 8.5 for the year 2070. Predicted area percentage > 100% and < 100% indicates gain and loss of area, respectively.
