The kiang, or Tibetan wild ass, is common in the grasslands of Changthang, numbering about 2,500 individuals. These animals are in conflict with the nomadic people of Changthang who hold the Kiang responsible for pasture degradation. There are about 200 snow leopards in Ladakh of an estimated 7,000 worldwide. The Hemis High Altitude National Park in central Ladakh is an especially good habitat for this predator as it has abundant prey populations. The Eurasian lynx, is another rare cat that preys on smaller herbivores in Ladakh. It is mostly found in Nubra, Changthang and Zangskar. The Pallas's cat, which looks somewhat like a house cat, is very rare in Ladakh and not much is known about the species. The Tibetan wolf, which sometimes preys on the livestock of the Ladakhis, is the most persecuted amongst the predators. There are also a few brown bears in the Suru Valley and the area around Dras. The Tibetan sand fox has been discovered in this region. Among smaller animals, marmots, hares, and several types of pika and vole are common.
