- Black rhinoceros - arid ecotype Diceros bicornis bicornis
- De Wintonís golden mole Cryptochloris wintoni
- Julianaís golden mole Neamblysomus julianae (Pretoria subpopn.)
- Ongoye red squirrel Paraxerus palliatus ornatus

Did you know? Julianaís Golden Mole
Bronberg Ridge - Julianaís golden mole, the third most critically endangered mammal species in South Africa, is found on the north-eastern slope of the 20km long Bronberg Ridge in Eastern Pre toria. One of only three populations of this species in the entire world, Julianaís golden mole is severely threatened by nearby up-market real estate development, roads, and an open-cast quartzite quarry on Bronberg Ridge.
Some genetic work done on the population of Julianaís golden mole found in the Kruger National Park has indicated that it may be a separate species. If this is the case, the golden moles on Bronberg Ridge will be in even more grave danger of extinction. Growing on the ridge is also an endemic plant species, Ceropegia decidua subsp Pretoriensis, which is also critically endangered.
