|White-bellied musk deer|
The white-bellied musk deer or Himalayan musk deer (Moschus leucogaster) is a musk deer species occurring in the Himalayas of Nepal, Bhutan, northern India including Sikkim, and China. It is listed as endangered by the IUCN because of overexploitation resulting in a probable serious population decline. It is the state animal of Uttarakhand.
White-bellied musk deer are very well adapted for high altitudes; they demonstrate such adaptations as well-developed dew claws, broad toes that provide increased stability on steep slopes, and a dense coat of coarse hairs with air-filled cells to insulate against the extreme temperature. While they lack antlers, a trait notable among all musk deer, they do possess a pair of enlarged and easily broken canines that grow continuously. The maximum length of these tusks is about 10 cm (4 in). These deer have a stocky body type; their hind legs are also significantly longer and more muscular than their shorter, thinner forelimbs. In place of running or leaping, this species tends to "bound." Finally, fawns of this species have white spots to help with camouflage, but as they mature these spots disappear.
The white-bellied musk deer has a waxy substance called musk that the male secrets from a gland in the abdomen. The deer use this to mark territories and attract females, but the musk is also been used in the manufacture of perfumes and medicines.
Distribution and habitat
Himalayan musk deer are found in parts of northern Afghanistan, Pakistan, Jammu and Kashmir, Tibet, Bhutan, Sikkim, Nepal, and in northern parts of India such as in (Himachal Pradesh, Uttarakhand, and Assam). They inhabit high alpine environments, with the lowest occurring at 2500 m above sea level. The species is endangered due to a high volume of illegal wildlife trade within its range.
Ecology and behaviour
Shy and secretive during the day, when it hides in dense cover, at night, the white-bellied musk deer emerges to feed in more open habitats. This species prefers to select the leaves of trees and shrubs with high protein and low fibre contents, but during the winter, it may subsist on poorer quality lichens. It may climb small trees to feed upon leaves that would otherwise be out of reach. The white-bellied musk deer is a fairly sedentary species, occupying a small home range of up to 22 hectares. The male is fiercely territorial, only allowing females to enter his range. Territories are marked by carefully placed defecation sites and strong-smelling secretions, which are placed onto the surrounding plants,
Males fight each other over females during the mating season, and use their long canines to fight and defend their territories. The females,though, hide from all the commotion. For the males to attract the females and bring them out from hiding, they use their strong smelling musk.
A female has one or two young at a time. The young musk deer live off their mother's milk till they are about six months old and able to eat regular foods available in the wild. At 16 to 24 months old, they become sexually mature.
As the musk the deer produces is in demand for the manufacture of perfumes and medicines, it is highly valuable. Since the species is endangered and hard to find, its value on the wildlife trade market is increased still further. The hunting and trade of the white-bellied musk deer is the main threat to the species. Deer musk may sell for as much as $45,000/kg, making it one of the most valuable animal-derived products in the world. Hunters catch and kill the deer using snares. Only males produce the musk, so this creates a problem because females and young are caught in the traps and killed.
The white-bellied musk deer is protected by law in Bhutan, Nepal, and India. In China, hunting may be permitted in some areas, although a license is required. It is listed as an endangered species in Pakistan and is also found in a number of protected areas throughout; however, the uneven enforcement of legislation across its range has meant little impact on preventing the rampant trade in the species. Improving the enforcement of antipoaching laws is a key priority for the conservation of this species.
Efforts being made
Captive farming for musk has been developed in China, and so far has shown that it is possible to extract musk from a deer without having to kill it. However, the captive deer succumb to disease and fighting and produce poorer quality musk. The killing of wild deer is thought to be the most cost-effective method of extracting musk. Open farming is a possible new way to extract the musk, whereby free-ranging or wild musk deer are caught and the musk then extracted, allowing the species to be conserved and survive.
