In terms of the mammal species, 73 species have been recorded, which is 48% of those in the province (n = 152), and 28% of those in the country (n = 260).  One species is listed as endangered under TOPS, and the National and Global Red Lists. Two species are Vulnerable according to the TOPS and National Red Listings. There are six species Protected according to the TOPS legislation, while 6 and 2 have been listed as Near Threatened, both Nationally and Globally respectively. There are 10 CITES listed species, which are mostly protected species. Seven species are listed as Extinct, such as the African elephant, Loxodonta africana, black rhinoceros Diceros bicornis minor and the lion Panthera leo. The largest ungulate species is the Kudu Tragelaphus strepsiceros, while the largest carnivore species are the leopard and brown hyena. Of particular interest, a small dispersing group of wild dog Lycaon pictus did wander through the area in 2012, so technically could be listed, though they are not year-round residents.  Of aquatic mammals, the hippopotamus Hippopotamus amphibius has been reintroduced onto at least one property, while the African clawless otter Aonyx capensis does occur throughout.

The mammal diversity is high due to species turnover along the transition between the Savannah bushveld and Highveld grasslands, where a combination of species can occur (Power, 2014). There is great potential in restoring the historical species richness, in particular with the large, high-profile large mammals.
