General: Athel Tamarisk (Tamarix aphylla) are tall, spindly trees with many drooping branches. Athel closely resembles Saltcedar, but Athel trees are tall compared to shrubby Saltcedars. Both were introduced into North America, but Athel Tamarisk are less invasive than Saltcedar.

In Athel Tamarisk, the stems appear jointed (if tiny cylindrical segments attached end to end). The joints are the leaves, which wrap around the stem, and the leaves are "mucronate," which means they end with a tiny point (if you look very closely).

Athel Tamarisk have been planted in the Lower Sonoran (Creosote-Bursage Flats) and Upper Sonoran (Mojave Desert Scrub) life zones.

Athel is an invasive weed. Around Las Vegas, this species is uncommon -- let's all work to make sure it stays that way. Keep an eye out for this species. Land managers are actively working to eradicate Athel, so hopefully you won't see it in too many places. Athel is on the Lake Mead NRA "Top 10 Invasive Species" list and on the Nevada State list of noxious weeds.

Family: Tamarisk (Tamaricaceae).

Other Names: Athel tree

Plant Form: Evergreen tree with a a rounded or irregular, spreading crown of many heavy, stout branches and long, drooping twigs.

Height: 30-60 feet.

Trunk: To 2.5 feet in diameter. Bark is thick and deeply furrowed into long ridges. The twigs are wiry, slender, drooping, and appear jointed.

Leaves: Tiny scales 0.06 inch long that conspicuously sheath (wrap around) the stems; not scale-like, but with a tiny point (mucronate leaves). Leaves not deciduous.

Flowers: Tiny white to pink flowers.

Seeds: Many, tiny, windblown seeds.

Habitat: Desert areas, usually planted along roadways, for shade, or windbreaks.

Distribution: Desert areas from south Texas to southern California.

Elevation: Below sea level to 5,000 feet.

Comments: Athel Tamarisk is an introduced species native to Africa and the Middle East that was planted in desert areas as a fast-growing tree for windbreaks, shade, and as an ornamental. It has escaped cultivation, but has not naturalized as much as Saltcedar, and recently is becoming a problem in some places.

Athel produces diffuse shade, but little that benefits the habitat or wildlife.
