Distribution of mammal species richness in Mauritania based on 100x100 km grid cells.
Left: extant species. Right: species listed as Near Threatened, Vulnerable, Endangered, and Critically Endangered at the national level according to the current study. Unsampled grid cells are marked (light grey). Mountain plateaus and escarpments (black dashed) and national parks (green shaded; in italics) are identified.
