Mammals of the
Great Himalayan National Park

Snow Leopard, Blue Sheep and Other High Himalayan Wildlife

A Continuous Mountain Refuge

The Great Himalayan National Park Conservation Area (GHNPCA) forms part of a larger, almost continuous block of protected habitat with Khirganga National Park, Pin Valley National Park and Rupi Bhaba Wildlife Sanctuary.

GHNP itself is unique among these: it has been fully notified, with all rights and concessions settled. Grazing and herb collection have been stopped inside the Park since 1999, so the human footprint is extremely low, especially in the upper valleys.

Across this connected landscape:

  • High-altitude alpine and glacial zones support wide-ranging species such as
    Snow Leopard (IUCN Endangered), Himalayan Brown Bear and Blue Sheep.

  • Temperate middle-altitude forests harbour Serow, Himalayan Tahr,
    Himalayan Musk Deer, Himalayan Black Bear and Ghoral.

  • Lower semi-tropical forests and riverine belts are home to Common Leopard,
    Barking Deer, monkeys, langurs, flying squirrels, martens and civets.

Although small in area, GHNPCA thus contains a full altitudinal sequence of habitats from lower broadleaf to glaciers – an almost complete showcase of Western Himalayan mammals.

A hunting ban in Himachal Pradesh (1986 onwards) has helped many species recover, but it has also increased crop and livestock depredation for poor villagers in the Ecozone, who now rely on labour-intensive methods of crop protection (night fires, drumming, scarecrows) rather than hunting or snaring.

Large Mammal Assemblage

More than 375 animal species are known from GHNPCA, including at least 31 mammal species documented to date. The Park brings together:

  • Two large cats

    • Snow Leopard and Common Leopard

  • Two bear species

    • Himalayan Black Bear and Himalayan (Asiatic) Brown Bear

  • Five main wild ungulates

    • Ghoral, Serow, Himalayan Tahr, Barking Deer, Himalayan Musk Deer

    • plus Blue Sheep (Bharal) above treeline

  • Two primates

    • Rhesus Macaque and Nepal Grey Langur

  • Two conspicuous large rodents

    • Indian Crested Porcupine and Giant Flying Squirrel

Historically, species like Sambar, Wild Boar, Ibex and Indian Wild Dog (Dhole) may have occurred here but are not confirmed in recent years.

A 35–45 km trek up any of the main valleys brings visitors into the high-altitude zone (3,500 m and above) where Blue Sheep, Snow Leopard, Himalayan Brown Bear, Himalayan Tahr and Musk Deer occur. The best viewing season is autumn (September–November) when animals start moving down from high ridges towards lower winter ranges.

Snow Leopard (Panthera uncia)

Flagship species of the GHNP high country, the Snow Leopard inhabits the Park’s inner, glaciated valleys, especially around the heads of the Tirthan, Sainj and Jiwa Nal. It is slightly smaller than the Common Leopard, with thick fur, long tail and beautifully rosetted coat that blends with broken rock and snow.

  • Range: Central Asian mountains from Afghanistan to Mongolia; Endangered in India

  • In GHNP: First confirmed in 1997 at Tirath, headwaters of the Tirthan River

  • Habitat: High-altitude cliffs, scree slopes, broken ridges above treeline

  • Prey: Mainly Blue Sheep, but also Himalayan Tahr, Musk Deer and smaller mammals

GHNP’s Snow Leopard habitat is continuous and largely free of human settlements, unlike adjoining Pin Valley where villages and transhumant grazing create conflict. This makes the Park a stronghold for secure, long-term Snow Leopard conservation, especially when considered together with Khirganga, Pin Valley and Rupi Bhaba.

India’s national Snow Leopard project (NCF–MoEFCC and partners) uses GHNP as part of a knowledge-based, community-inclusive conservation framework, integrating issues like transhumance, livestock insurance and climate-change vulnerability.

Blue Sheep / Bharal (Pseudois nayaur)

Blue Sheep are the principal wild prey of Snow Leopard in GHNPCA. Small, light-bodied wild sheep, males carry long, sweeping horns and have black markings on face and flanks.

  • Altitude: Typically 3,500 m up to the limit of vegetation

  • Habitat: Steep grassy slopes near cliffs

  • Seasonality: In spring (April–May) herds descend to valley bottoms; often seen near Suketi (upper Tirthan) and at the head of Jiwa Nal.

Historically, there was competition with domestic sheep/goats on alpine meadows. Since grazing has been stopped in the Park, Blue Sheep herds are relatively secure and, together with strong populations in neighbouring PAs, provide a robust prey base for Snow Leopard.

Himalayan (Asiatic) Brown Bear (Ursus arctos isabellinus)

The largest mammal in GHNPCA, the Himalayan Brown Bear is a light, sandy or reddish-brown bear found above treeline in summer.

  • Altitude in GHNP: c. 3,300–4,450 m

  • Best viewing: Spring and summer at river origins: Tirath (Tirthan), Rakti Sar, Sartoo and other alpine meadows

  • Diet: Mainly herbivorous (grasses, roots, herbs) but also marmots, pikas, insects and carrion

They rarely raid crops because they stay mostly at higher altitudes, but may kill livestock grazed above treeline. Brown Bears use steep meadows and rocky slopes, generally away from the forested Black Bear zone.

Himalayan Tahr (Hemitragus jemlahicus)

A wild goat of cliffs and precipices, the Himalayan Tahr is one of GHNP’s most characteristic ungulates.

  • Altitude: ~2,000–4,000 m (sometimes higher)

  • Appearance: Males with dark shaggy ruff and pale mantle, often silhouetted on ridges

  • Behaviour: Gregarious; groups of 5–20 commonly seen in GHNP

Good viewing points include Nada and Supakhani (where Sainj and Tirthan valleys meet) and high meadows such as Dhel. Kanawar Wildlife Sanctuary adjoining GHNP is another stronghold.

Himalayan Musk Deer (Moschus leucogaster)

A small, antler-less deer of dense subalpine scrub and dwarf rhododendron (“krummholz”) near tree line.

  • Altitude: c. 2,800–4,000 m

  • Special features: Males have long, backward-curving upper canines and a valuable musk gland (“pod”) in the abdomen

  • Threats: Intensive poaching for musk, snaring with wire nooses

In some GHNP localities densities reach 6–9 animals/km², but their secretive habits and camouflage make sightings rare. Innovative community outreach (e.g. youth patrols collecting snares and using “street theatre” to publicise the law) has been used to discourage poaching.

Indian Pika (Ochotona roylei)

Small, rabbit-like mammals living among rocks in subalpine and alpine zones; common in boulder scree and meadows near campsites. They cut and store grass in burrows for winter, and are a key prey species for martens and birds of prey.

Mid-Altitude and Lower-Forest Species (Below ~3,000 m)

Serow (Capricornis thar)

A shy, heavily built goat-antelope of steep, forested gorges, often associated with sacred groves (dev bans) and dense ringal bamboo.

  • Rarely seen, but camera traps have confirmed its presence in Sainj and Tirthan valleys.

  • Uses regular latrine sites, so large piles of droppings can reveal its territory.

Red Fox (Vulpes vulpes)

Common above treeline and on open slopes; often watches trekkers from nearby rocks. Predates ground birds and small mammals, and scavenges around campsites.

Rhesus Macaque (Macaca mulatta)

Commonest monkey of northern India; widespread in villages and lower Park forests. In the Ecozone it is a major crop raider, especially in orchards and maize.

Barking Deer / Northern Red-faced Muntjac (Muntiacus vaginalis)

A small forest deer of lower temperate hills (1,500–2,500 m). Rarely seen because it keeps to cover; more vulnerable to poaching than cliff-dwelling Ghoral.

Himalayan Ghoral (Naemorhedus goral)

Perhaps the most frequently seen large mammal along Park trails.

  • Altitude: up to ~3,000 m, most common below 2,500 m

  • Habitat: Open, grassy slopes near cliffs, especially at dawn and dusk

  • Listed as Near Threatened, but populations in GHNPCA are strong.

Indian Crested Porcupine (Hystrix indica)

Large, nocturnal rodent with long quills; widespread up to about 2,500 m. A serious crop pest in villages and often killed by farmers, but important component of the Park’s mammal community.

Species with Wide Altitude Ranges

Himalayan (Asiatic) Black Bear (Ursus thibetanus)

The common bear of GHNP forests, smaller than Brown Bear, black with a white chest crescent.

  • Altitude: Forested areas below ~3,300 m

  • Diet: Mostly vegetarian but opportunistic omnivore; raids maize fields and can kill livestock.

Signs (scats, tree scratches, feeding signs) occur throughout the Park; villagers report both crop damage and occasional conflict.

Leopard (Panthera pardus)

A generalist predator of forests and scrub from foothills up to ~3,600 m.

  • More often detected in the Ecozone and village fringes than inside the core Park.

  • Takes domestic livestock and dogs, especially where wild prey is scarce near settlements.

Yellow-throated Marten (Martes flavigula)

A striking, agile carnivore of forests from 1,700–3,500 m. Usually seen in pairs or small groups, moving rapidly with bounding gait. Diet includes rodents, pikas and birds; tracks are common in winter snow.

Giant Flying Squirrel (Petaurista petaurista)

Large nocturnal gliding squirrel of temperate forests up to ~3,500 m. Easily recognised by characteristic leaf-feeding signs (central holes bitten from folded leaves) and used as prey by large raptors and carnivores.

Nepal Grey Langur (Semnopithecus schistaceus)

Long-limbed, thickly furred langurs of mid- and high-altitude forests (1,650–3,600 m), feeding largely on oak and other tree foliage. Considered relatively benign by villagers (locally gooni), and sometimes thought to deter more destructive rhesus macaques.

Conservation Status and Protection

Most large mammals of GHNPCA are listed under Schedule I of the Wildlife (Protection) Act, 1972, affording them the highest legal protection in India.

​

IUCN assessments range from Endangered (Snow Leopard, Himalayan Musk Deer) and Vulnerable (Asiatic Black Bear, Leopard) to Near Threatened (Himalayan Tahr, Ghoral, Serow) and Least Concern for some smaller species.

​

Because human use has been removed from the core Park, poaching is easier to control within GHNP than in surrounding landscapes where grazing and herb collection continue. So far, no major declines have been detected in Park populations, but continued monitoring (camera traps, transect surveys, sign counts) is essential, especially for elusive species like Snow Leopard and Musk Deer.

People, Livelihoods and Conflict

Large mammals frequently interact with local communities:

  • Past livestock losses to Brown Bear and Leopard on alpine meadows once prompted shepherds to carry firearms and keep fierce guard dogs.

  • Today, with grazing removed from the Park, predation has shifted mainly to the Ecozone and adjoining sanctuaries, where livestock is still taken by Leopards and Black Bears.

  • Villagers invest significant time and effort guarding crops and animals, often with limited compensation.

 

Effective conservation in GHNPCA therefore depends on:

  • Maintaining strong protection inside the Park;

  • Supporting conflict-mitigation and insurance schemes in neighbouring areas;

  • Involving local communities in monitoring, eco-tourism, and conservation awareness.
