Hello Friends, Welcome to PrepMate Classes! Endangered species is one of the favourite topic of UPSC. In recent years, there has been many questions on this topic. In this lecture, we will discuss about the important endangered terrestrial species in India. IUCN (International Union for Conservation of Nature) is a NGO based in Switzerland which is engaged in conservation of both flora and fauna. It annually publishes the ‘Red Book’. Red Book consists of species of both plants and animals which are endangered. Some of the endangered terrestrial species in India are listed below. We will consider them one by one. 1. Large Rock Rat or Elvira Rat: It is a Medium sized rat and is nocturnal. It is found in Eastern Ghats in Tamil Nadu. 2. Namdapha Flying squirrel: It is found in Namdapha (a place in Arunachal Pradesh). It is also known as flying squirrel because it jumps from high trees and glides through the air like a kite. It is killed by native communities for food. 3. Malabar Civet: It is found in Malabar region of Kerala (Western Ghats). It is nocturnal in nature. Its habitat is both plains and hill slopes. 4. Kashmir stag/ Hangul: It is a sub-species of deer. It is the state animal of Jammu and Kashmir. It is also found in Himachal Pradesh. 5. Wild Ass: It is Found in Rann of Kutch, Gujarat. Its population has significantly reduced on account of spread of disease among the species and habitat degradation due to excessive salt in soil. 6. Golden Langur: It is a former species of monkey. Its fur is golden in colour. It is found in western Assam. 7. Himalayan deer or White bellied musk deer: It is found in Kashmir, Uttarakhand, Sikkim. It lacks horns on head called Antlers. It possesses a pair of enlarged canines that grow continuously. Musk deer is called so because of the presence of the gland in the male musk deer. Musk is used for making medicines, perfumes, etc. 8. Lion tailed Macaque: It looks like a monkey. It is found at places where both Western and eastern ghats meet in states of Karnataka, Kerala and Tamil Nadu. 9. Nilgiri Tahr: It is the State animal of Tamil Nadu. It has two large horns on its head. 10. Great Indian one-horned rhinoceros: It is found in Assam in Kaziranga National Park, Manas National park and Pabitora wildlife Sanctuary. It is killed because of oriental belief that its horn consists of medicinal properties. 11. Tibetian Antelope/Chiru: It is found in Tibet and Himalayan region. It is hunted for its wool which is used to make shahtoosh shawls, scarfs, etc. 12. Black Buck: It is Killed for its meat and hunting events. It exhibits sexual dimorphism i.e large differences between male and female of the species. Black Buck in India is found in states of Rajasthan, Gujarat, Odisha, West Bengal and many other regions of India. 13. Red Panda: It is found at lesser altitude in the Himalayas in Sikkim, Arunachal Pradesh and Assam. 14. Sangai Deer: It is a Subspecies of brow-antlered deer found only in Manipur, India. It is also the state animal of Manipur. It lives in the Keibul Lamjao national park, about 45 km from Imphal, capital of Manipur. 15. Kharai Camel : Kharai camel or swimming camels are found in Gujarat’s Bhuj area. Gujarat is the only home to Kharai camel. Kharai camel can live in both coastal and dry ecosystems. It grazes on mangrove trees and is tolerant to high saline water. It can swim up to three kilometres into the sea in search of mangroves. The camel is distinct from other camels because of its rounded back, long and thin legs and small feet. Its population is less than 10,000. Its population is available in the wild habitat as well as in the domesticated habitat. Let us now see past year prelim questions asked on this topic. 2013 prelims In which of the following states is the lion-tailed macaque found in its natural habitat? Lion Tale Macaque is found in Tamil Nadu, Kerala and Karnataka. Thus, option A is the correct answer. 2016 prelims What is/are unique about ‘Kharai camel’, a breed found in India? Only statements I and 2 are correct. Thus, option A is the correct answer. For Best learning you can watch this video along with Prepmate-Cengage UPSC series which is available online as well as offline. Book feature: complete subject in a single book with practice and past year questions at the end of the chapters. Model answers for UPSC Mains from authors. Using the application Prepmate and web portal Prepmate.in you can access comprehensive digital support in form of videos, mock prelims, answer writing practice and regular updates.

Characteristics

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.[3] 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).[4][5] 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 secretes from a gland in the abdomen. The deer use this to mark territories and attract females, but the musk is also used in the manufacture of perfumes and medicines.[6]

Distribution and habitat

Himalayan musk deer occurs in parts of northern Afghanistan, Pakistan, Tibet, Nepal, Bhutan, and in northern India such as in Jammu and Kashmir, Himachal Pradesh, Uttarakhand, Sikkim and Arunachal Pradesh. It inhabits high alpine environments above altitudes of 2,500 m (8,200 ft).[1]

Ecology and behaviour

During the day, white-bellied musk deer hide in dense cover and are shy and secretive. At night, they emerge to feed in more open habitats, and preferably select leaves of trees and shrubs with high protein and low fibre contents. During the winter, they subsist on poorer quality lichens, and even climb small trees to feed upon leaves that would otherwise be out of reach.[7]

They are fairly sedentary occupying a small home range of up to 22 hectares. Male are fiercely territorial, only allowing females to enter their range. Territories are marked by carefully placed defecation sites and strong-smelling secretions, which are placed onto the surrounding plants.[6] Males fight each other over females during the mating season, and use their long canines to fight and defend their territories. The females hide from all the commotion. For the males to attract the females and bring them out from hiding, they use their strong smelling musk.[citation needed]

A female has one or two young at a time. The young musk deer live off their mother's milk until 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.[6][7]

Himalayan musk deer can live for up to 10 to 14 years.[citation needed]

Their predators include leopard snow leopard, Eurasian lynx, red fox, gray wolf. Juveniles were also killed by yellow-throated marten and large raptors.[8]

Threats

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.[9] 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.

Conservation

The white-bellied musk deer is protected by law in Bhutan, Nepal, and India.[citation needed] In China, hunting may be permitted in some areas, although a license is required. It is listed as an endangered species in Pakistan[citation needed] 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.[10] 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.[11] 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.[11]
