Ladakh is the home to endemic Himalayan wildlife, such as the bharal, yak, Himalayan brown bear, Himalayan wolf and the iconic snow leopard. Hemis National Park, Changthang Cold Desert Wildlife Sanctuary, and Karakorum Wildlife Sanctuary are protected wildlife areas of Ladakh. The Mountain Institute, the Ladakh Ecological Development Group and the Snow Leopard Conservancy work on ecotourism in rural Ladakh. For such an elevated, arid area, Ladakh has great diversity of birds — 318 species have been recorded. Many of these birds reside at or seasonally breed in high-altitude wetlands, such as Tso Moriri, or near rivers and water sources.
