Description

Habitat

Biome: Terrestrial

Ecology: Wild Yak live in the alpine tundra and cold desert regions of the northern Tibetan plateaux, Xinjiang, and Qinghai—almost uninhabited mountainous areas of 4,000–6,000 m altitude . In Chang Tang Reserve in northwest Tibet, which is the species’ last stronghold, the average annual precipitation is only 100–300 mm, much of it falling as hail and snow; lakes are generally saline and surface water is scarce. Temperatures can fall below -40°C. Vegetation is sparse, and is dominated by grasses, sedges, forbs , and low or procumbent shrubs ; much of it can be classed as alpine, or high cold steppe (Schaller and Gu Binyuan 1994).
