The plant is found in sandhills , deserts and sand ridges, where it often forms pure stands, with an average density up to 400-500 trees a hectare. The white saxaul is a hardy tree that can grow in nutritionally poor soil and can tolerate drought. The tree

48-532: Is 1.5 mm ( 1 ⁄ 16  in) in diameter. The fruiting period is October to November. The species was first published in 1829 by Carl Anton von Meyer as Anabasis ammodendron C.A.Meyer . In 1851 Alexander Bunge combined it to genus Haloxylon as Haloxylon ammodendron (C.A.Meyer) Bunge . Synonyms are: Arthrophytum ammodendron (C.A.Meyer) Litw ., Arthrophytum haloxylon Litw ., Haloxylon pachycladum M.Pop ., and Haloxylon aphyllum (Minkw.) Iljin. . A related saxaul species

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. It also grows in

It has a brown trunk up to 25 centimetres (10 inches) in diameter. The wood is heavy and coarse and the bark is spongy and water-soaked. The branches of the current year are green; older branches are brown, or gray to white. The leaves are reduced to very small cusp-like scales, so that

When the Russian Imperial Navy brought the first steamships into

128-526: Is in leaf all year, and flowers in May–June. The plant's extensive root system is useful for stabilising sandy soils. The wood is durable and heavy and is used in general carpentry.

The uranium mines at Tortkuduk and Moiynkum are operated by the Franco - Kazakh firm KATCO . This Kazakhstan location article

160-513: The desert'. 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 . The thick bark of the saxaul tree stores water. Quantities of the bark may be pressed for drinking water, making saxaul an important source of water in arid regions where it grows. Saxaul

176-558: The hard and resinous wood was difficult to cut, and knotty and crooked saxaul logs could not be stored space-efficiently in the ships' holds. Therefore, starting from 1852, the Aral Flotilla switched to coal as its main fuel, despite the remarkable costs of shipping it by caravan from Orenburg . The Uzbek government has also planted the trees in the Aral Desert to help prevent the spread of toxic salts left behind when
