Scientists have identified 36 global biodiversity hotspots that contain at least 1,500 endemic (unique) plant species and have lost more than 70 per cent of their original natural flora. One of these hotspots — the Mountains of Central Asia — is the centre of origin of such crops as apples, pears, apricots, pistachios, almonds, wheat, onions, tulip and others.
The Mountains of Central Asia biodiversity hotspot is formed by two major mountain systems, the Pamir and the Tien Shan. It covers an area of 800,000 square kilometres and stretches across seven countries, including south-eastern Kazakhstan, eastern Uzbekistan, western China, north-eastern Afghanistan (Wakhan), the Koytendag Mountains in south-eastern Turkmenistan and almost all of the two mountain countries of Kyrgyzstan and Tajikistan.
The highest biodiversity is observed at elevations between 1,000 and 3,000 metres above sea level. Some mountain peaks reach heights of 7,000 m and are covered by glaciers. The mountains of Central Asia are home to about half of the world’s population of the snow leopard (Panthera uncia), 500 species of birds, and more than 5,000 species of vascular plants, 1,500 of which are unique. The diversity of reptiles is greatest in the lower reaches and in the desert area, while amphibians and fish are rather scarce in the region.
