The bharal (Pseudois nayaur), also called the blue sheep, is a caprine native to the high Himalayas. It is the only member of the genus Pseudois.  It occurs in India, Bhutan, China (in Gansu, Ningxia, Sichuan, Tibet, and Inner Mongolia), Myanmar, Nepal, and Pakistan.  The Helan Mountains of Ningxia have the highest concentration of bharal in the world, with 15 bharals per km2 and 30,000 in total.
Its native names include yanyang (岩羊) in Mandarin, bharal, barhal, bharar, and bharut in Hindi, na or sna in Tibetan and Ladakh, nabo in Spitian, naur in Nepali and na or gnao in Bhutan.  The bharal was also the focus of George Schaller and Peter Matthiessen's expedition to Nepal in 1973. Their personal experiences are well documented by Matthiessen in his book, The Snow Leopard. The bharal is a major prey of the snow leopard.
These medium-sized caprids are 115 to 165 cm (45 to 65 in) long along the head-and-body, with a tail of 10 to 20 cm (3.9 to 7.9 in). They stand 69 to 91 cm (27 to 36 in) high at the shoulder. Body mass can range from 35 to 75 kg (77 to 165 lb). Males are slightly larger than females. Dense coat is slate grey in colour, sometimes with a bluish sheen. The underparts and backs of the legs are white, while the chest and fronts of the legs are black. Separating the grey back and white belly is a charcoal-colored stripe. The ears are small, and the bridge of the nose is dark. The horns are found in both sexes and are ridged on the upper surface. In males, they grow upwards, then turn sideways and curve backward, looking somewhat like an upside-down mustache. They may grow to a length of 80 cm (31 in). In females, the horns are much shorter and straighter, growing up to 20 cm (7.9 in) long.  
The dwarf blue sheep or dwarf bharal (formerly described as Pseudois schaeferi), also known as rong-na in Tibetan, was an alleged species of Pseudois endemic to Sichuan-Tibet in China. It apparently inhabited low, arid, grassy slopes of the upper Yangtze gorge in Batang County of the Sichuan Province, and a small part of the Tibet Autonomous Region. It was recorded as differing from the bharal primarily in size, with adult males weighing around 35 kg (half as much as the bharal), less sexual dimorphism occurring in the species, and females of the two species being very similar. Its coat was described as a steely grey with a silvery sheen, with darker general colouration than the bharal, and the horns of the male were smaller, thinner and more upright, with no inward curl. There were only 200 individuals estimated to be alive in 2000, which prompted the IUCN (classifying it as a subspecies of P. nayaur, as P. n. schaeferi) classified it as Endangered. 
However, a 2012 genetic analysis of Chinese bharal found no indication that it was either a distinct species or subspecies, instead finding to be a morphologically distinct variant of P. n. szechuanensis. The American Society of Mammalogists also follows these results, considering P. schaeferi to be conspecific with P. nayaur.  
Bharal are active throughout the day, alternating between feeding and resting on the grassy mountain slopes. Due to their excellent camouflage and the absence of cover in their environment, bharal remain motionless when approached. Once they have been noticed, however, they scamper up to the precipitous cliffs, where they once again freeze, using camouflage to blend into the rock face. Population densities in Nepal were found to be 0.9–2.7 animals per km2, increasing to a maximum of 10 animals in the winter, as herds congregate in valleys.  Bharal are mainly grazers, but during times of scarcity of grass, they switch to browsers, eating herbs and shrubs.  A high degree of diet overlap between livestock (especially donkeys) and bharal, together with density-dependent forage limitation, results in resource competition and a decline in bharal density.  Where they overlap, they are the favored prey of snow leopards, Himalayan wolves, and leopards, with a few lambs falling prey to foxes or eagles. 
The rutting of the bharal starts towards late November and continues until mid-January. During the rut, male bharal use multiple strategies for mating, namely tending, blocking, and coursing.  Their lambs are born in late June and July.[ citation needed ]
The bharal is categorised as Least Concern by the International Union for Conservation of Nature. The population faces threats - poaching for meat and competition with livestock. Poaching, however, is uncommon due to the unsuitable conditions of its habitat. Similarly, livestock do not generally frequent the mountainous regions where bharal occur; even if they do coexist, no notable detrimental effect on the bharal has been observed. 
Many Buddhist monasteries protect the bharal found around them, but lately, issues of crop damage caused by bharal have started to arise in areas such as the Spiti Valley.
The Himalayas, or Himalaya, is a mountain range in Asia, separating the plains of the Indian subcontinent from the Tibetan Plateau. The range has some of the planet's highest peaks, including the very highest, Mount Everest. Over 100 peaks exceeding 7,200 m (23,600 ft) in elevation lie in the Himalayas.
The goa, also known as the Tibetan gazelle, is a species of antelope that inhabits the Tibetan plateau.
Ladakh is a region administered by India as a union territory which constitutes a part of the larger Kashmir region and has been the subject of dispute between India, Pakistan, and China since 1947. Ladakh is bordered by the Tibet Autonomous Region to the east, the Indian state of Himachal Pradesh to the south, both the Indian-administered union territory of Jammu and Kashmir and the Pakistan-administered Gilgit-Baltistan to the west, and the southwest corner of Xinjiang across the Karakoram Pass in the far north. It extends from the Siachen Glacier in the Karakoram range to the north to the main Great Himalayas to the south. The eastern end, consisting of the uninhabited Aksai Chin plains, is claimed by the Indian Government as part of Ladakh, and has been under Chinese control since 1962.
The urial, also known as the arkars or shapo, is a wild sheep native to Central and South Asia. It is listed as Vulnerable on the IUCN Red List.
The argali, also known as the mountain sheep, is a wild sheep that roams the highlands of western East Asia, the Himalayas, Tibet, and the Altai Mountains.
Hemis National Park is a high-elevation national park in Ladakh, India. Globally famous for its snow leopards, it is believed to have the highest density of them in any protected area in the world. It is the only national park in India that is north of the Himalayas, the largest notified protected area in India and is the second largest contiguous protected area, after the Nanda Devi Biosphere Reserve and surrounding protected areas. The park is home to a number of species of endangered mammals, including the snow leopard. Hemis National Park is India's protected area inside the Palearctic realm, outside the Changthang Wildlife Sanctuary northeast of Hemis, and the proposed Tso Lhamo Cold Desert Conservation Area in North Sikkim.
The flora and fauna of Ladakh was first studied by Ferdinand Stoliczka, an Austrian Czech palaeontologist, who carried out a massive expedition in the region in the 1870s. The fauna of Ladakh have much in common with that of Central Asia generally, and especially those of the Tibetan Plateau. An exception to this are the birds, many of which migrate from the warmer parts of India to spend the summer in Ladakh. For such an arid area, Ladakh has a great diversity of birds — a total of 318 species have been recorded. Many of these birds reside or breed at high-altitude wetlands such as Tso Moriri.
The Ladakh Range is a mountain range in central Ladakh in India with its northern tip extending into Baltistan in Pakistan. It lies between the Indus and Shyok river valleys, stretching to 230 miles (370 km). Leh, the capital city of Ladakh, is on the foot of Ladakh Range in the Indus river valley.
The Changtang is a part of the high altitude Tibetan Plateau in western and northern Tibet extending into the southern edges of Xinjiang as well as southeastern Ladakh, India, with vast highlands and giant lakes. From eastern Ladakh, the Changtang stretches approximately 1,600 kilometres (990 mi) east into Tibet as far as modern Qinghai. The Changtang is home to the Changpa, a nomadic Tibetan people. The two largest settlements within the Tibetan Changtang are Rutog Town the seat of Rutog County and Domar Township the seat of Shuanghu County.
Tso Moriri or Lake Moriri or "Mountain Lake", is a lake in the Changthang Plateau of Ladakh in India. The lake and surrounding area are protected as the Tso Moriri Wetland Conservation Reserve.
Shey Phoksundo National Park is the largest and only trans-Himalayan national park in Nepal. It was established in 1984 and covers an area of 3,555 km2 (1,373 sq mi) in the districts of Dolpa and Mugu in the Mid-Western Region, Nepal. The protected area ranges in elevation from 2,130 to 6,885 m. Phoksundo Lake is the park's prominent feature, located at an elevation of 3,612 m (11,850 ft).
The Himalayan wolf is a canine of debated taxonomy. It is distinguished by its genetic markers, with mitochondrial DNA indicating that it is genetically basal to the Holarctic gray wolf, genetically the same wolf as the Tibetan and Mongolian wolf, and has an association with the African wolf. No striking morphological differences are seen between the wolves from the Himalayas and those from Tibet. The Himalayan wolf lineage can be found living in Ladakh in the Himalayas, the Tibetan Plateau, and the mountains of Central Asia predominantly above 4,000 m (13,000 ft) in elevation because it has adapted to a low-oxygen environment, compared with other wolves that are found only at lower elevations.
The Western Himalayan alpine shrub and meadows is a montane grasslands and shrublands ecoregion of Nepal, India, and Tibet, which lies between the tree line and snow line in the western portion of the Himalaya Range.
The Eastern Himalayan alpine shrub and meadows is a montane grasslands and shrublands ecoregion of Bhutan, China, India, Myanmar, and Nepal, which lies between the tree line and snow line in the eastern portion of the Himalaya Range.
The snow leopard, also known as the ounce, is a felid in the genus Panthera native to the mountain ranges of Central and South Asia. It is listed as Vulnerable on the IUCN Red List because the global population is estimated to number fewer than 10,000 mature individuals and is expected to decline about 10% by 2040. It is threatened by poaching and habitat destruction following infrastructural developments. It inhabits alpine and subalpine zones at elevations of 3,000–4,500 m (9,800–14,800 ft), ranging from eastern Afghanistan, the Himalayas and the Tibetan Plateau to southern Siberia, Mongolia and western China. In the northern part of its range, it also lives at lower elevations.
The Trans himalaya, or "Gangdise – Nyenchen Tanglha range", is a 1,600-kilometre-long (990 mi) mountain range in China, India and Nepal, extending in a west–east direction parallel to the main Himalayan range. Located north of Yarlung Tsangpo river on the southern edge of the Tibetan Plateau, the Transhimalaya is composed of the Gangdise range to the west and the Nyenchen Tanglha range to the east.
Kibber, also Kibber Khas and Khyipur, is a village high in the Spiti Valley in the Himalayas at 4,270 m (14,010 ft) in Himachal Pradesh in northern India. It contains a monastery and is a base for visiting the Kibber Wildlife Sanctuary. It is located 19 km (12 mi) from Kaza and a bus service connects them in the summer months. Agriculture forms the backbone of the local economy and lush green fields are abundant. It is the base for visitors to the Kibber Wildlife Sanctuary, home to about 30 snow leopards. Treks to neaby peaks and to a high pass in the Zanskar range between Spiti and Ladakh start from Kibber.
Chang Tang National Nature Reserve lies in the northern Tibetan Plateau. It is the third-largest land nature reserve in the world, after the Northeast Greenland National Park and Kavango-Zambezi Transfrontier Conservation Area, with an area of over 334,000 km2 (129,000 sq mi), making it bigger than 183 countries. Administratively, it lies in Xainza County and Biru County of the Nagqu Prefecture. With the more recently established adjoining reserves listed below there is now a total of 496,000 km2 of connected Nature Reserves, which represents an area almost as large as Spain and bigger than 197 other countries.
The Tibetan Plateau alpine shrublands and meadows ecoregion covers the middle transition zone between the northern and southern regions of the Tibetan Plateau. The region supports both cold alpine steppe and meadows across a broad expanse of the plateau. Wild deer, antelope, and sheep roam the grasslands, but the habitat is increasingly being used to graze domestic livestock.
