The yak (Bos grunniens and Bos mutus) is a long-haired bovid found throughout the Himalaya region of south Central Asia, the Tibetan Plateau and as far north as Mongolia and Russia. Most yaks are domesticated, Bos grunniens. There is also a small, vulnerable population of wild yaks, Bos mutus. In the 1990s, a concerted effort was undertaken to help save the wild yak population.

Wild yaks (Bos grunniens mutus or Bos mutus, Tibetan: འབྲོང་, Wylie: ‘brong) usually form herds of between ten and thirty animals. They are insulated by dense, close, matted under-hair as well as their shaggy outer hair. Yaks secrete a special sticky substance in their sweat which helps keep their under-hair matted and acts as extra insulation. This secretion is used in traditional Nepalese medicine. Many wild yaks are killed for food by hunters in China; they are now a vulnerable species
