The Tien Shan mountain range covers most of the Kyrgyz Republic, southern Kazakhstan, and smaller areas of Uzbekistan, China, and Tajikistan. This territory plays an exceptional role in conserving biodiversity and maintaining environmental sustainability in Central Asia. In 2004, Conservation International (CI) identified the Tien Shan range as a “biodiversity hotspot” based on the high numbers of endemic species and the significant level of threat—the concentration of species in Western Tien Shan is 63 times higher for birds and 37 times higher for mammals than the average for Central Asia.
