Nepal, April 20 -- When Nepal decided to mark the annual National Yak Day on 20 April 2025, it celebrated an animal that has been the backstay of mountain livelihoods for centuries.

The sure-footed yak is more than just an iconic bovine. It is the guardian of the high Himalaya and integral to the identity of pastoralist communities. Yaks provide a lifeline: hauling goods across treacherous trails, providing milk, butter and warm wool for clothing, and providing dung that serves as fertiliser and fuel.

(In English, yak is used to refer to both the male and female, while in Himalayan languages it refers strictly to the male, while females are called dri or nak. A dzo or chauri is a crossbreed between a yak and a domestic cow.)
