Common Names
Wild Yak (English); Jangali Chauri Gai (Nepali)
Species Description
Long shaggy black-dark brown coat, grey muzzle,
thick tail, both sexes grow horns which curve
upwards. These horns are larger compared to
domesticated Yak.
Species Ecology
Wild Yak live in alpine tundra, grasslands and cold
desert regions, and move seasonally, descending
into lower valleys in the winter. Wild Yak feed mostly
on grasses, sedges and forbs.
Wild Yak are seasonal breeders. Age at first
reproduction is between three and four years (this
may vary depending on environmental conditions)
and after a gestation period of 258 to 270 days a
single calf is born.
Conservation Status
Global: Vulnerable A2ac+3c+4c [Regionally Extinct
in Nepal]
National: Data Deficient [possibly Regionally Extinct
in Nepal]
Rationale for assessment: This species has been
assessed as Data Deficient due to the lack of reliable
information on population size and distribution. No
studies have been carried out to confirm whether
this species still occurs in Nepal.
