The Kalahari, while popularly known as a desert, has a variety of localised environments, including some verdant and technically non-desert areas. The Succulent Karoo is home to over 5,000 species of plants, nearly half of them endemic; approximately 10 percent of the world's succulents are found in the Karoo.

In an area of about 600,000 km in the south and west of the Kalahari, the vegetation is mainly xeric savanna. This area is the ecoregion identified by World Wide Fund for Nature as Kalahari xeric savanna AT1309. Typical savanna grasses include ("Schmidtia", "Stipagrostis", "Aristida", and "Eragrostis") interspersed with trees such as camelthorn ("Acacia erioloba"), grey camelthorn ("Acacia haematoxylon"), shepherd’s tree ("Boscia albitrunca"), blackthorn ("Acacia mellifera"), and silver cluster-leaf ("Terminalia sericea").
