The primary threats to the mountain zebra include competition with domestic livestock, hunting and persecution, habitat loss due to conversion to agriculture (2), and the risk of the two subspecies breed with each other leading to a loss of genetic diversity (2) (10).
Hartmann's mountain zebras live in direct conflict with livestock farmers, with available grazing ground becoming particularly scarce in many parts of Namibia where very little rainfall has occurred for several years. As a result, more and more Hartmann's mountain zebras are being culled, both legally and illegally. Furthermore, due to the region's poor economy and scarce resources, poaching for food has increased rapidly over the last few years, since the zebra offers a relatively large amount of meat. The situation in Angola has been exacerbated by war, in which many soldiers and civilians have been in dire need of meat (9).
The Cape mountain zebra formerly inhabited all the mountain ranges of the southern Cape Province of South Africa, but by 1997 less than 750 were believed to survive (5). Reaching a devastating all-time low of just 91 individuals in 1950 (10), this subspecies is considered the largest mammal in South Africa to have come so close to extinction, a fate that sadly awaited the quagga (E. quagga). Although probably never particularly numerous, numbers declined as herds had to compete against sheep and cattle for grazing, and as habitat was increasingly converted into farmland. Hunting was also uncontrolled and this zebra was a popular victim, its hide (skin) allegedly much sought after for the manufacturing of ‘grain bags'. Thankfully, the Cape mountain zebra's population eventually climbed back up to approximately 1,200 individuals in 1998 (7).
The non-profit organisation Etusis Foundation has been established in Namibia for the conservation of Hartmann's Mountain Zebra. The foundation conducts research on the subspecies, and focuses on educating farmers and raising public and government awareness about the plight this subspecies faces (9).
Despite its bleak outlook over the last century, concerted conservation efforts mean that Cape mountain zebra numbers are now increasing. The Mountain Zebra National Park was established in 1937 to help save this subspecies, and there are a further two original sub-populations protected in Kamanassie Nature Reserve and Gamka Mountain Reserve. There are also currently about another 11 formally protected, reintroduced sub-populations, including those in Karoo National Park, Karoo Nature Reserve, Addo Elephant National Park, Commando Drift Nature Reserve, De Hoop Nature Reserve, Cape Point Nature Reserve and Tsolwana Game Ranch (2) (7) (10). Conservation efforts by the private sector have also had an important impact, such as the recent purchase by Bushmans Kloof Wilderness Reserve of another twenty Cape mountain zebras from a private seller, making a total of over 30 animals held at the reserve, probably the largest privately owned herd of Cape mountain zebra in the world (7). Although this subspecies still occupies a precarious existence, the dramatic increase in its population over the last 50 years is considered a great conservation success story, and a testament to the ongoing, collaborative efforts of many individuals and parties committed to saving this African icon (7). The current conservation objective is to build up numbers to a target of 2,500 animals as quickly as possible in order to help ensure the long-term survival of the Cape mountain zebra (10).
