Succulent Karoo 115 reptile species, 48 are endemic and 15 are strict endemics. The Sperrgebiet region is a hotspot for an unusual tortoise, the Nama padloper. Endemism is present, but less pronounced, among the Succulent Karoo’s bird and mammal populations. The ecoregion has been designated a biodiversity hotspot by Conservation International. Succulent Karoo The Succulent Karoo is a desert ecoregion of South Africa and Namibia. The Succulent Karoo stretches along the coastal strip of southwestern Namibia and South Africa's Northern Cape Province, where the cold Benguela Current offshore creates frequent fogs. The ecoregion extends inland into the uplands of South Africa's Western
Karoo into the increasingly arid Bushmanland towards the north-west. To the north and north-east, it fades into the savannah and grasslands of Griqualand West and the Highveld. The boundary to the east grades into the grasslands of the Eastern Midlands. The Great Karoo is itself divided by the Great Escarpment into the Upper Karoo (generally above 1200–1500 m) and the Lower Karoo on the plains below at 700–800 m. A great many local names, each denoting different subregions of the Great Karoo, exist, some more widely, or more generally, known than others. In the Lower Karoo, going from west to east,
