Fig. 6

The overall pattern of top priority sites using CAZ (left) or ABF (right), both using bias-free predictions from Maxent. Each map shows the summed rankings of the top 17% sites from the four surrogates used. Shading within current PAs (blue borders) are not shown to highlight the pattern for PA expansion (darker shading indicates higher rankings). The pattern for each species group is shown in Additional file 1: Figure S12. For equivalent maps using elastic net, see Additional file 1: Figure S13
