The giraffe is common in both eastern and southern Africa. Giraffes can inhabit savannas , grasslands, or open woodlands. They prefer areas enriched with acacia growth. They drink large quantities of water and, as a result, they can spend long periods of time in dry, arid areas. When searching for more food they will venture into areas with denser foliage. Giraffes are hunted for their hides, hair, and meat. In addition, habitat destruction also hurts the giraffe. In the Sahel trees are cut down for firewood and to make way for livestock. Normally, giraffes are able to cope with livestock since they feed in the trees above their heads. The giraffe population is increasingly shrinking in West Africa. However, the populations in eastern and southern Africa are stable and, due to the popularity of privately- owned game ranches and sanctuaries (i.e. Bour-Algi Giraffe Sanctuary ), are expanding. The giraffe is a protected species in most of its range. The total African giraffe population has been estimated to range from 110,000 to 150,000. Kenya (45,000), Tanzania (30,000), and Botswana (12,000), have the largest national populations. [13] An unexpected danger to giraffes in captivity is that, as they are typically the tallest objects in a zoo, giraffes are at increased risk of being struck by lightning . In the wild, this hazard is reduced by the presence of trees; as well, the giraffe's natural habitat range has an extremely low occurrence of lightning -- NASA's satellite lightning detection system indicates that the area receives an average of less than one cloud-to-ground flash per square kilometre per year. The Dama gazelle inhabits all of the Sahara from east to west and the Sudan. The Dama Gazelle ( Nanger dama [formerly: Gazella dama] ), also known as the Addra Gazelle , is a species of gazelle . It lives in Africa in the Sahara desert and migrates south in search of food during the dry season. After the rains return and the desert plants turn green, they move north back to the Sahara. Poaching and destruction of their habitat have greatly diminished their numbers, and they no longer live in large herds. It is white with a tannish-brown head and neck. The Dama Gazelle also has a subspecies, the Mhorr Gazelle, Gazella dama mhorr , which is extinct in the wild. Its numbers have fallen by 80% over the last decade, and the Dama Gazelle is now listed as Critically Endangered, though there are still 2000 left. They occur in poor countries and little action is taken to protect the species, the national parks are not well guarded and poachings still occur. Captive populations are managed in zoos in Africa and America.

The schimitar-horned oryx is confined to a narrow strip between Mauritania and the Red Sea. Scimitar Oryx natively inhabit steppe and desert where they eat leaves , grass and fruit . They form herds of mixed sex containing up to seventy animals. Scimitar Oryx were hunted for their horns, almost to extinction. Where once they occupied the whole
