Bos grunniens Linnaeus, 1766 和 Bos mutus (Przewalski, 1883) 分别是通常称为牦牛的牛科动物的家养和野生形式。 B. mutus栖息于青藏高原偏远的高海拔高山草甸和高山草原，在青藏高原滚动到山地地区，B. grunniens广泛分布在中国和中亚其他地区，在世界其他地方并不常见。 B. mutus 的种群数量大幅减少，并且在其剩余分布范围内变得支离破碎；数量最多的是西藏北部和青海西部。由于偷猎和与家畜的竞争，B. mutus 很脆弱。尽管尚未对 B. mutus 进行过全面调查，但在青藏高原的偏远地区，其数量可能不超过 15,000 只； B. grunniens 数量约为 1,400 万。 DOI：10.1644/836.1。
Bos grunniens Linnaeus, 1766, and Bos mutus (Przewalski, 1883) are the domestic and wild forms, respectively, of the bovid commonly called the yak. B. mutus inhabits remote high-elevation alpine meadows and alpine steppe in rolling to mountainous terrain in the Tibetan Plateau, and B. grunniens is maintained widely in China and other parts of Central Asia, and uncommonly elsewhere in the world. Populations of B. mutus are substantially reduced and fragmented throughout its remaining range; the largest numbers occur in northern Tibet and western Qinghai. B. mutus is vulnerable because of poaching and competition with domestic livestock. Although no complete survey of B. mutus has been conducted, there are probably no more than 15,000 remaining in remote areas of the Tibetan Plateau; B. grunniens numbers about 14 million.
