The genus Tamarix (tamarisk, salt cedar, taray) is composed of about 50–60 species of flowering plants in the family
Description
They are
Tamarisks are characterized by slender branches and grey-green foliage. The bark of young branches is smooth and reddish brown. As the plants age, the bark becomes gray-brown, ridged and furrowed.[4]
The leaves are scale-like, almost like that of junipers,[6] 1–2 mm (1/20" to 1/10") long, and overlap each other along the stem. They are often encrusted with salt secretions.[4]
The pink to white flowers appear in dense masses on 5–10 cm (2" to 4") long spikes at branch tips from March to September,[4][7] though some species (e.g., T. aphylla) tend to flower in the summer until as late as November.[8]
Ecology
Tamarix aphylla can spread both
These trees grow in disturbed and undisturbed streams, waterways, bottom lands, banks, and drainage washes of natural or artificial water bodies, moist rangelands and pastures.[citation needed]
Whether Tamarix species are fire-adapted or not is unclear, but in many cases a large proportion of the trees are able to resprout from the stump after fires, although not notably more so than other riverine species. They likely cannot resprout from root suckers. In some habitats where they are native, wildfire appears to favour the establishment of riverine trees such as Populus, to the detriment of Tamarix. Conversely, they do appear to be more flammable, with more dead wood produced and debris held aloft. In the southwestern USA, most stands studied appear to be burning at faster intervals than they can fully mature and die of natural causes.[11]
Tamarix species are used as food plants by the larvae of some Lepidoptera species including Coleophora asthenella which feeds exclusively on T. africana.[12]
Uses
- Tamarisk species are used as ornamental shrubs, windbreaks, and shade trees:[13] notably T. ramosissima[11] and T. tetrandra.[14]
- In the American Southwest, Tamarisk was introduced to help erosion control.[15]
- In Greece Tamarisk – known locally as almyriki is cooked and eaten as a wild green vegetable.[16]
- The wood was used by the Saka (combined with wood and ibex horn) to produce tremendously powerful bows hundreds of years before the common era.[17]
- The wood may be used for carpentry or firewood: it is a possible agroforestry species.[18][19]
- At certain times of year, scale insects feeding upon the tender twigs of tamarisk plants excrete a sweet substance known as honeydew, which has been gathered for use as a food source and sweetener for thousands of years. The substance is also known locally as manna, and some scholars have suggested that this substance is the biblical manna that fed the Israelites during their flight from Egypt, though others dispute this interpretation.[20]
- Plans are being made for the tamarisk to play a role in anti-desertification programs in China.[21][22]
Invasive species
In some specific
Competition with native plants
Research on competition between tamarisk seedlings and co-occurring native trees has found that Tamarix seedlings are not competitive over a range of environments,
In a 2013 study which examined if native plant growth was hindered by the
Because it is much more efficient at both obtaining water from drying soil and conserving water during drought, it can outcompete many native species, especially after the habitat is altered by controlling flood regimes and disturbance of water sources.[23] Because the trees are able to concentrate salts on the outside of their leaves, dense stands of the tree will form a layer of high salinity on the topsoil as the leaves are shed.[23] Although this layer is easily washed off during flooding events, in areas where the rivers are channelled and floods are controlled, this salty layer inhibits the germination of a number of native plants.[11] However, a study involving more than a thousand soil samples across gradients of both flood frequency and Tamarix density concluded that "flooding may be the most important factor for assessing floodplain salinity" and "soils under Tamarix canopies had lower surface soil salinity than open areas deprived of flooding suggesting that surface evaporation may contribute more to surface soil salinity than Tamarix".[40]
Investigation of effects of invasion
Tamarix species are commonly believed to disrupt the structure and stability of North American native plant communities and degrade native wildlife habitat, by outcompeting and replacing native plant species, salinizing soils, monopolizing limited sources of moisture, and increasing the frequency, intensity, and effect of fires and floods [
Controls
Pest populations of tamarisk in the United States can be dealt with in several ways. The National Park Service has used the methods of physically removing the plants, spraying them with herbicides, and introducing northern tamarisk beetles (Diorhabda carinulata) in the national park system. Various attempts to control tamarisk have been implemented on federal lands including Dinosaur National Monument, San Andres National Wildlife Refuge, and White Sands Missile Range.[49][50] After years of study, the USDA Agricultural Research Service found that the introduced tamarisk beetles (Diorhabda elongata) eat only the tamarisk, and starve when no more is available, not eating any plants native to North America.[51]

In North America
The tamarisk was introduced to the United States as an ornamental shrub, a windbreak, and a shade tree in the early 19th century. In the 1930s, during the Great Depression, tree-planting was used as a tool to fight soil erosion on the Great Plains, and different trees were planted by the millions in the Great Plains Shelterbelt, including salt cedars.[53][54]
Eight species are found in North America. They can be divided into two subgroups:[9]
- Evergreen species
Tamarix aphylla (Athel tree), a large evergreen tree, does not sexually reproduce in the local climate and is not considered a seriously invasive species.[9] The Athel tree is commonly used for windbreaks on the edge of agricultural fields and as a shade tree in the deserts of the Southwestern United States.[55]
- Deciduous species
The second subgroup contains the deciduous tamarisks, which are small, shrubby trees, commonly known as "saltcedars". These include T. pentandra, T. tetrandra, T. gallica, T. chinensis, T. ramosissima and T. parviflora.[9]
Cultural history

- In the Myricawas a young woman who was transformed into a tamarisk.
- In the Iliad 21.18 Achilles leaves his spear aside among the tamarisks by the banks of the river Xanthus.

- In Shahnameh, only a tamarisk arrow to the eye can wound the otherwise invincible Prince Esfandiar.[citation needed]
- In the Quran 34:16, the people of Saba were punished when "[Allah] converted their two garden (rows) into gardens producing bitter fruit and tamarisks...".[49]
- In Egyptian mythology, the body of Osiris is hidden for a time in a tamarisk tree in Byblos, until it was retrieved by Isis. A reference to this is also made in the computer game, Age of Mythology, in which the head of Osiris is said to be hidden inside the trunk of a great tamarisk tree.[citation needed]
- According to the New Larousse Encyclopedia of Mythology, the tamarisk plant is a favorite of the Greek god Apollo.[citation needed]
- Australian author Gerald Murnane's debut novel Tamarisk Row (1974) is set on a farm bordered by a row of tamarisks in a northern Victorian town on the edge of the Mallee. In the novel, tamarisks are described as "famous for their hardiness" and as markers of the limits of "the most desolate land of all." (p.4)
- The tamarisk features heavily in Paolo Bacigalupi's short story, "The Tamarisk Hunter". The story depicts a man in a drought-stricken near future who uproots and collects tamarisk plants in exchange for state-paid bounties. The story is collected in Bacigalupi's short story collection, Pump Six.
