The IUCN red list classifies these tortoises as endangered, and their populations are quickly diminishing in the wild. These tortoises are in danger because of traffic on roadways, habitat deterioration, and pet trade hunting. For this species, the most common predation comes from dogs, birds, and pigs. Humans brought these dogs and pigs into the habitat of the speckled cape tortoise, which means they are not native to the area.
