[1] Siberia, North Mongolia, Russia, North China and Korea – M. m. moschiferus[1] Russian Far East – M. m. turovi Verkhoyansk Ridge – M. m. arcticus Sakhalin – M. m. sachalinensis Korea – M. m. parvipes The earliest findings of the musk deer belong to the Upper and Middle Pleistocene and they all come from places in China and from the south of the Russian Far East.

[citation needed] The musk deer also inhabited Sakhalin Island before its separation from the continent during the Quaternary period.

Tusks that are longer and stronger create a more intimidating stance and become more attractive to females as the offspring of that male are likely to become healthier.

When marking their territories, musk deer gather fallen branches, tree trunks, as well as plant stems, and place them in a circle.

While placing the various branches around the circle, the deer will often do an olfactory examination and turn the back of its body towards the marked territories.

[6] Most Siberian musk deer are generally nocturnal, inhabiting the mountainous taiga and found in shrub-covered slopes where foods are abundant.

The rocky location provides crevices and crags for the musk deer to hide from many predators, such as Siberian tiger, Amur leopard, snow leopard, Eurasian lynx, wolf, Red fox, brown bear, Asian black bear, wolverine and yellow-throated marten.

Musk deer have a preference for easily digestible nutritious foods that are both rich in protein and low in fibre.

In 2016, the Korean company Sooam Biotech was reported to be attempting to clone the Siberian musk deer to help conserve the species.

World population: 230,000 Declining Siberian musk deer preputial gland secretions are constituted of free fatty acids and phenols (10%), waxes (38%) and steroids.

200 million cm3[5] of China's forest resources were cut down in the past 25 years in order to harvest the timber stock in trade for commerce.
