The snow leopard (') once ranged throughout the Himalaya, Tibet, and as far as the Sayan Mountains on the Mongolian-Russian border; and in elevation from 1800 m to 5400 m. They are extremely shy and hard to spot, and as such not well known. It is believed that there are about 200 in Ladakh.

There are also a very few "brown bears" (' / ') in the Suru valley and the area around Dras. The red fox is common, and Tibetan sand fox has recently been discovered in this region (both: ').
