The Basics

  • Domestic Yak (Bos grunniens):
    Tamed and bred by humans for thousands of years, these yaks are central to life in the Himalayas, Tibet, Mongolia, and beyond.
  • Wild Yak (Bos mutus):
    A rare and elusive species, the wild yak roams remote parts of the Tibetan Plateau. It’s larger, tougher, and far less accustomed to human presence.

Key Differences

FeatureDomestic YakWild Yak
SizeSmaller, males average 1,200 lbs (540 kg)Larger, males can exceed 2,000 lbs (900 kg)
TemperamentDocile, used to humansWary, aggressive if threatened
ColorationWide range: black, brown, white, spottedMostly dark brown to black
HornsShorter and more variedLong, sweeping horns
CoatShaggy, but varies by breedThicker and denser for harsh climates
Use by HumansMilk, meat, wool, transport, fuelNot domesticated—occasionally hunted
StatusWidespread and essential in mountain lifeVulnerable, with shrinking habitat

Interbreeding

Domestic and wild yaks can interbreed, and in some regions, this happens naturally. While this increases genetic diversity in domestic herds, it poses a challenge for conserving pure wild yak populations. Conservationists are working to protect the genetic integrity of wild yaks in remote areas.


Habitat and Range

  • Domestic yaks are found across Central Asia, wherever people live in high-altitude areas.
  • Wild yaks stick to the most remote, windswept corners of Tibet and western China, far from roads and villages.

Conservation Status

The wild yak is listed as “Vulnerable” by the IUCN. Its main threats are:

  • Habitat degradation
  • Hunting
  • Hybridization with domestic herds

Meanwhile, domestic yaks are thriving and remain vital to highland economies and cultures.
