About

Haloxylon ammodendron, variously called the saxaul (Russian: саксау́л, romanized: saksaúl), black saxaul, also spelled sacsaoul or saksaul is a plant belonging to the family Amaranthaceae. "Saksaul" is a common Turkic word that entered Russian through Kazakh.

Where it grows

The saxaul is distributed in the lowlands of Central Asia – including southern Kazakhstan, Turkmenistan, western Uzbekistan, Iran, west Afghanistan, Mongolia and China, namely Xinjiang and Gansu. It also occurs incidentally in the west of Kirghizstan and Tajikistan. It is a psammophyte, and grows in sandy deserts, on sand dunes, and in steppe up to 1,600 m (5,200 ft) above sea level. In Central Asia it often forms 'saxaul forests', in Iran it usually grows more scattered.

Uses

The saxaul is planted on a large scale in the afforestation of arid areas in China. Being highly drought-resistant, it has played an important role in the establishment of shelter belts and the fixation of sand dunes as a counter to desertification.
