From high mountain livestock to North American herds

Domestic yaks belong to a livestock tradition shaped by the Tibetan Plateau, where grazing, cold weather and demanding terrain influenced their usefulness. Their value extends beyond meat: milk, insulating fiber and carrying capacity connect the animal to several forms of rural work. North American conservation therefore concerns a particular managed population and its ancestry, rather than a claim that yaks originated here. Learning that distinction prevents the history of an imported livestock population from being confused with the geography of its ancestral species.
