Range of the Siberian musk deer |
The Siberian musk deer (Moschus moschiferus) is a musk deer found in the mountain forests of Northeast Asia. It is most common in the taiga of southern Siberia, but is also found in parts of Mongolia, Inner Mongolia, Manchuria and the Korean peninsula.
Their small shape allows them to hide from predators through tiny openings in the rocky terrain and also allows them to run exceptionally fast from their predators. Although bearing fangs, Siberian musk deer are actually herbivores, with their main source of nutrients being lichens. [3]
Due to the severe amount of poaching for its musk gland, the deer population is continuing to decrease. It is expected that the population will be reduced to at least 30% over the next three generations. However, efforts from each of the cited countries are beginning to restore the musk deer's population. [1]

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 evolving in the mountain forests of eastern Asia spread widely since the Pleistocene in the mountain regions of Central, South-East Asia and in the north it spread to 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. [4] [ failed verification ]
It takes approximately a year for the Siberian musk deer to reach maturity, with an average deer living 10–14 years.
During breeding season, male deer will grow tusks instead of antlers. [3] These tusks are used to compete with other males and attract females. 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.
Once the male and the female deer have procreated, the females will become pregnant for over 6 months. Females can give birth to 1–3 offspring, usually between the months of May through June. [5]
Musk will mark their territory,[ clarification needed ] warning trespassing deer not to cross the boundary. 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. Another way the Siberian musk deer will mark its territory is by defecating in already marked territories or unclaimed 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. During periods of winter, musk deer can survive in even poorer food quality ranging in foods that are low in proteins but are high in energy and can be easily digested. [7]
The majority of their diet consists mostly of lichens, pine needles, leaves, and tree barks. During the winter, 99% of the musk deer's diet is lichens. Siberian musk deer have a preference for easily digestible nutritious foods.
The species is largely nocturnal and migrates only over short distances. It prefers altitudes of more than 2,600 m (8,500 ft). Adults are small, weighing 7–17 kg (15–37 lb).
The Siberian musk deer is classified as Vulnerable by the IUCN. It is hunted for its musk gland, which fetches prices as high as $45,000 per kilogram. Only a few tens of grams can be extracted from an adult male. It is possible to remove the gland without killing the deer, but this is seldom done. In 2016, the Korean company Sooam Biotech was reported to be attempting to clone the Siberian musk deer to help conserve the species. [8]
The most striking characteristics of the Siberian musk deer are its tusks and kangaroo-like face. Males grow the teeth for display instead of antlers. [9] [10]

Siberian musk deer preputial gland secretions are constituted of free fatty acids and phenols (10%), waxes (38%) and steroids. Cholestanol, cholesterol, androsterone, Δ4-3α-hydroxy-17-ketoandrostene, 5β,3α-hydroxy-17-ketoandrostane, 5α,3β,17α-dihydroxyandrostane, 5β,3α,17β-dihydroxyandrostane and 5β,3α,17α-dihydroxyandrostane can be isolated from the steroid fraction. 3-Methylpentadecanone (muscone) was not identified among the secretion lipids. [12]
The decline of the Siberian musk deer's population began in China where the deer population was most abundant. Most notably in the Sichuan plains, the musk production accounted for 80% of the domestic trade in the 1950s. [5] New sightings of musk deer were later spotted in upper northeast Asia and Russia; these places where the deer were spotted soon opened their own musk markets. After the 1980s, the production begins to steadily decline due to hunting for their musk glands. The cycle of over-harvesting the deer's musk continued until the exploitation severely reduced the musk deer's population.
Another threat comes from the habitat loss by deforestation. For a long period, China cut more of its forest than they could replant. 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. Deforestation is a severe threat to the musk deer's long-term survival because the deer can only live in a few areas.
The Siberian musk deer is considered vulnerable, but is slowly declining to endangerment. In Russia, the Siberian musk deer is protected as Very Rare under part 7.1 of the Law of the Mongolian Animal Kingdom (2000) and also under the 1995 Mongolian Hunting Law. [1] The musk deer are also protected under the National Parks, which account for approximately 13% of the Siberian musk deer population.
At the international level, trading musk is controlled through CITES. All trades regarding musk are subject to strict regulation to avoid exploitation of the survival of the deer. [13]
The Russian Far East is a region in Northeast Asia. It is the easternmost part of Russia and the Asian continent; and is administered as a part of the Far Eastern Federal District, which is located between Lake Baikal in eastern Siberia and the Pacific Ocean. The area's largest city is Khabarovsk, followed by Vladivostok. The region shares land borders with the countries of Mongolia, China, and North Korea to its south, as well as maritime boundaries with Japan to its southeast, and with the United States along the Bering Strait to its northeast.
Musk is a class of aromatic substances commonly used as base notes in perfumery. They include glandular secretions from animals such as the musk deer, numerous plants emitting similar fragrances, and artificial substances with similar odors. Musk was a name originally given to a substance with a strong odor obtained from a gland of the musk deer. The substance has been used as a popular perfume fixative since ancient times and is one of the most expensive animal products in the world. The name originates from the Late Greek μόσχος 'moskhos', from Persian mushk and Sanskrit मुष्क muṣka derived from Proto-Indo-European noun múh₂s meaning "mouse". The deer gland was thought to resemble a scrotum. It is applied to various plants and animals of similar smell and has come to encompass a wide variety of aromatic substances with similar odors, despite their often differing chemical structures and molecular shapes.
Moschidae is a family of pecoran even-toed ungulates, containing the musk deer (Moschus) and its extinct relatives. They are characterized by long 'saber teeth' instead of horns, antlers or ossicones, modest size and a lack of facial glands. While various Oligocene and Miocene pecorans were previously assigned to this family, recent studies find that most should be assigned to their own clades, although further research would need to confirm these traits. As a result, Micromeryx, Hispanomeryx, and Moschus are the only undisputed moschid members, making them known from at least 18 Ma. The group was abundant across Eurasia and North America during the Miocene, but afterwards declined to only the extant genus Moschus by the early Pleistocene.
Musk deer can refer to any one, or all seven, of the species that make up Moschus, the only extant genus of the family Moschidae. Despite being commonly called deer, they are not true deer belonging to the family Cervidae, but rather their family is closely related to Bovidae, the group that contains antelopes, bovines, sheep, and goats. The musk deer family differs from cervids, or true deer, by lacking antlers and preorbital glands also, possessing only a single pair of teats, a gallbladder, a caudal gland, a pair of canine tusks and—of particular economic importance to humans—a musk gland.
The Siberian tiger or Amur tiger is a population of the tiger subspecies Panthera tigris tigris native to the Russian Far East, Northeast China and possibly North Korea. It once ranged throughout the Korean Peninsula, but currently inhabits mainly the Sikhote-Alin mountain region in southwest Primorye Province in the Russian Far East. In 2005, there were 331–393 adult and subadult Siberian tigers in this region, with a breeding adult population of about 250 individuals. The population had been stable for more than a decade because of intensive conservation efforts, but partial surveys conducted after 2005 indicate that the Russian tiger population was declining. An initial census held in 2015 indicated that the Siberian tiger population had increased to 480–540 individuals in the Russian Far East, including 100 cubs. This was followed up by a more detailed census which revealed there was a total population of 562 wild Siberian tigers in Russia. As of 2014, about 35 individuals were estimated to range in the international border area between Russia and China.
The water deer is a small deer species native to Korea and China. Its prominent tusks, similar to those of musk deer, have led to both subspecies being colloquially named vampire deer in English-speaking areas to which they have been imported. It was first described to the Western world by Robert Swinhoe in 1870.
The Siberian jay is a small jay with a widespread distribution within the coniferous forests in North Eurasia. It has grey-brown plumage with a darker brown crown and a paler throat. It is rusty-red in a panel near the wing-bend, on the undertail coverts and on the sides of the tail. The sexes are similar. Although its habitat is being fragmented, it is a common bird with a very wide range so the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
Preputial glands are exocrine glands that are located in the folds of skin front of the genitals of some mammals. They occur in many species, including canids, mice, ferrets, rhinoceroses, and even-toed ungulates and produce pheromones. The preputial glands of female animals are sometimes called clitoral glands.
The Siberian roe deer, eastern roe deer, or Asian roe deer, is a species of roe deer found in northeastern Asia. In addition to Siberia and Mongolia, it is found in Kazakhstan, the Tian Shan Mountains of Kyrgyzstan, eastern Tibet, the Korean Peninsula and forested regions of northern China.
The white-bellied musk deer or Himalayan musk deer is a musk deer species occurring in the Himalayas of Nepal, Bhutan, India, Pakistan and China. It is listed as endangered on the IUCN Red List because of overexploitation resulting in a probable serious population decline.
The yellow-throated marten is a marten species native to the Himalayas, Southeast and East Asia. Its coat is bright yellow-golden, and its head and back are distinctly darker, blending together black, white, golden-yellow and brown. It is the second-largest marten in the Old World, after the Nilgiri marten, with its tail making up more than half its body length.
The black musk deer or dusky musk deer is a species of even-toed ungulate in the family Moschidae. It is found in Bhutan, China, India, Myanmar, and Nepal.
The greater mouse-deer, greater Malay chevrotain, or napu is a species of even-toed ungulate in the family Tragulidae found in Sumatra, Borneo, and smaller Malaysian and Indonesian islands, and in southern Myanmar, southern Thailand, and peninsular Malaysia. Its natural habitat is subtropical or tropical, moist, lowland forest.
The Alpine musk deer is a musk deer species native to the eastern Himalayas in Nepal, Bhutan and India to the highlands of Tibet.
Micromeryx is an extinct genus of musk deer that lived during the Miocene epoch. Fossil remains were found in Europe and Asia. The earliest record (MN4) of the genus comes from the Sibnica 4 paleontological site near Rekovac in Serbia.
Deer musk is a substance with a persistent odor, obtained from the caudal glands of the male musk deer.
The Kashmir musk deer is an endangered species of musk deer native to Afghanistan, India, and Pakistan. Recent studies have shown that the species is also native to western Nepal. This species was originally described as a subspecies to the alpine musk deer, but is now classified as a separate species. The deer stand at 60 cm (24 in) tall, and only males have tusks and they use them during mating season to compete for females.
The preorbital gland is a paired exocrine gland found in many species of artiodactyls, which is homologous to the lacrimal gland found in humans. These glands are trenchlike slits of dark blue to black, nearly bare skin extending from the medial canthus of each eye. They are lined by a combination of sebaceous and sudoriferous glands, and they produce secretions which contain pheromones and other semiochemical compounds. Ungulates frequently deposit these secretions on twigs and grass as a means of communication with other animals.
The Altai alpine meadow and tundra ecoregion is a terrestrial ecoregion covering the higher elevation of the Altai Mountains at the center of the "X" formed by the borders separating Russia, Kazakhstan, China, and Mongolia. The mountain peaks are the farthest north in Central Asia, separating the plains of Siberia to the north from the hot, dry deserts to the south. Altitudes above 2,400 meters display characteristics of tundra, with patches of alpine meadows and some trees immediately below the treeline. The ecoregion is in the montane grasslands and shrublands biome, and the Palearctic realm, with a humid continental climate. It covers an area of 90,132 square kilometres (34,800 sq mi).
