Input: Context: The Cape mountain zebra Equus zebra zebra is a subspecies of the mountain zebra named for Cape Province of South Africa and found in the Western Cape and Eastern Cape areas. They mainly eat grass but if little food is left they will eat bushes. It has been a separate species than the Hartmann's mountain zebra but this is not supported by genetic evidence (see Mountain zebra#Taxonomy). Consequently it was only considered a subspecies in Mammal Species of the World.
