The ten countries/regions with the highest percentages of the total underestimated wader biodiversity areas estimated by comparing SDM generated hotspot maps and BirdLife range maps.

These figures denote the disparity between the richness estimates for the two approaches. Minimum, maximum, range and standard deviation (STD) values are of the difference between two estimate approaches, hence a positive value indicates SDMs estimates greater species richness in the cells compared to BirdLife estimates while a negative value indicates a lower species richness from the SDM biodiversity map compared to BirdLife estimates.
