Threatened Species Richness - Mammals

Africa’s extraordinary richness in biodiversity and ecosystem services comprises a strategic asset for sustainable development. Yet the decline and loss of biodiversity hampers the sustainable social and economic targets set by African countries. The International Union for the Conservation of Nature (IUCN)'s Red List of Threatened Species is the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species. This map shows the richness in mammal species based on the IUCN ranges (the species geographical distribution). Areas with a high species richness are shown in shades of red: more mammal species potentially occur in these areas.

As the species ranges have not been refined by altitude and landcover (i.e. Area of Habitat), there may be a fair amount of unsuitable habitat in the raw ranges, resulting in errors of commission. Global species maps from the red list represent current, known limits of distribution for individual species within their native historical range. Although these maps have many uses, they generally have a coarse resolution and consequent limitations. Species ranges are mapped as generalized polygons which often include areas of unsuitable habitat, and therefore species may not occur in all of the areas where they are mapped. In general, for range-restricted taxa, ranges are mapped with a higher degree of accuracy, sometimes down to the level of individual subpopulations, compared with more widely distributed species.
