Around a quarter of Himalayan snow leopard and wolf diets are livestock, the rest being wild prey, according to a study published February 8, 2017 in the open-access journal PLOS ONE by Madhu Chetri from Inland Norway University of Applied Sciences, Norway, and colleagues.

Killing livestock creates conflicts between top predators and pastoral communities, and is a main challenge for conserving snow leopards, which are endangered, and Himalayan wolves, which are rare. These wolves prefer the open grasslands and alpine meadows that are also frequented by pastoral herders, and snow leopards prefer the steep terrain associated with montane pastures. To assess prey preferences of these carnivores, Chetri and colleagues analyzed DNA and hairs in 182 snow leopard scats and 57 wolf scats collected in the Central Himalayas, Nepal.

Critically endangered and ancient Himalayan wolf needs global conservation attention

Although the Himalayan wolf is visibly distinct from its European cousin, its current distribution has mostly been a matter of assumption, rather than evident truth. The most ancient wolf lineage, known to science, has been listed as Critically Endangered in the National Red List.

Now, an international research team, led by Madhu Chetri, graduate student at the Hedmark University of Applied Sciences, Norway, report the wolf from Nepal's largest protected area, thus confirming its existence in the country. Their findings are published in the open access journal ZooKeys.

When compared to the European wolf, this one stands out with its smaller size, unusually longer muzzle and stumpy legs. Another clearly distinctive feature is the white colouration around the throat, chest, belly and inner part of the limbs. On the other hand, its characteristic woolly body fur has given the subspecies the common name 'woolly wolf'.

However, the distinctiveness of the Himalayan wolf is far more than skin-deep. The authors note that recent studies have already revealed that these wolves have split as a separate branch within the 'tree of life' so long ago that they are divergent from the whole globally distributed wolf-dog clade. Having undergone such an isolated evolution, the Himalayan wolf is considered of particular conservation concern.
