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").
