Snow Leopard

The snow leopard is the big cat almost no one sees. It lives higher, in colder, emptier country than any other large cat, and it has become the symbol of some of the least-explored wilderness left on Earth.

Overview

Snow leopards inhabit the cold, arid, near-vertical landscapes of High Asia — the Himalaya, the Karakoram, the Hindu Kush, the mountains of Mongolia and southern Siberia, and the vast Tibetan Plateau. Their range spans twelve countries, but the total wild population is small and thinly spread: an individual snow leopard may hold a home range of hundreds of square kilometres.

Built for the mountains

Everything about the snow leopard is tuned to altitude and cold:

• Fur up to 12 cm long, over a dense woolly undercoat, and a fur-covered belly for lying on frozen ground.
• Paws that are broad and heavily furred, spreading the cat’s weight on soft snow and gripping rock.
• A short, deep chest and enlarged nasal passages that warm and humidify the thin, cold air before it reaches the lungs — and powerful hindquarters for climbing.
• The tail — nearly a metre long, thick and furred, used as a balancing pole on cliff ledges and as a wrap-around blanket when the cat rests.

Its pale grey coat, patterned with dark rosettes and spots, is so effective against snow and scree that snow leopards routinely walk past researchers unnoticed.

Diet and hunting

Snow leopards are ambush hunters of steep ground. They stalk along ridgelines and rock faces, using the terrain for cover, and launch downhill onto prey — mainly blue sheep (bharal) and ibex, supplemented with marmots, pikas, hares, and game birds. A snow leopard can leap 15 m across a gully and can bring down an animal three times its weight, then drag the carcass to a sheltered spot and feed on it for several days.

Where wild prey has been reduced, snow leopards take domestic goats and sheep, sometimes killing many animals in a single enclosure — the main source of conflict with herders.

Behaviour and life cycle

Snow leopards are solitary and communicate at a distance by scent-marking rocks and scraping the ground along regular travel routes. Mating is in late winter, and after a roughly 100-day pregnancy the female gives birth in a rocky den to two or three cubs, which stay with her for 18 months to two years, learning to hunt on the terrain they will inherit.

Threats and conservation

The snow leopard is Vulnerable and declining. Because it lives at such low density in such remote country, even small losses matter:

• Poaching for its pelt and, increasingly, for bones and body parts substituted into the trade once fed by tigers.
• Retaliatory killing by herders after livestock losses.
• Prey depletion as wild sheep and goats are hunted and outcompeted by domestic herds.
• Habitat loss and fragmentation from mining, roads, and infrastructure, and a warming climate that is pushing the tree line — and farming — up the mountainsides into snow leopard range.

Community programmes that combine predator-proof corrals, livestock insurance, and a financial stake in living snow leopards have reduced killings in several regions.
