Endangered because of hunting for meat and horns
The Banteng is a relative of the cow, and used to live all over Southeast Asia. However, it has already disappeared from several areas, and its numbers have declined in areas where it still lives today. One of the reasons for this is hunting. The Banteng is hunted for its meat and horns. As forests are rapidly being turned into farmland, there are fewer and fewer places where the Banteng can live. Because the shy Banteng abandons areas when humans come near, it is thought that it has lost more habitat than just those areas that have been turned into farmland.

Under pressure from its domesticated cousins?
The Banteng is also under pressure from animals called Bali cattle. The ancestors of these cattle are the Banteng themselves. Because Banteng sometimes mate with Bali cattle, there are fewer and fewer wild Banteng. Additionally, offspring of Banteng and Bali cattle are at risk of disease from domesticated cattle. As wild animals are not used to diseases from domesticated animals, there is a risk that disease will spread rapidly if even one animal gets sick.
