Biological controls for SALTCEDAR

Saltcedar leaf beetle, Diorhabda elongata

Teton County Weed & Pest Saltcedar

Saltcedar - The Jackson Hole Weed Management has worked with its partners in a cooperative effort called “The Snake River Project” to survey for and eradicate saltcedar infestations on the Snake River. The JHWMA has been successful at receiving funding from grants and partners to fund this effort. Crews from Teton County Weed & Pest and Grand Teton National Park, with the occasional help of volunteers float stretches of the river and stop at islands to survey and control saltcedar.

SALTCEDAR — Tamarix ramosissima Ledeb.

Tamaricaceae — (Tamarisk family)

Deciduous or evergreen shrubs or small trees, five to twenty feet tall. Bark on saplings and smooth woody stems are dark brown to reddish-brown. Leaves are small and scale like, on highly-branched slender green stems. Flowers are pink to white, five-petalled and borne in fingerlike clusters. Saltcedar, also called tamarisk, was introduced from Eurasia and is now widespread in the United States. Small flower tamarisk (T. parviflora DC.) is similar in appearance, but has four-petalled flowers, with brown to deep purple bark on stems. Small flower tamarisk was introduced from Southern Europe, and is also widespread. Both species are used as ornamentals, but have escaped and become naturalized along streams, canals and reservoirs in much of the West.

Growth Habit: Evergreen shrub or small tree, up to 30` tall, spread by seed.

Leaves: Small scale like, resemble cedars, salty residue collects on foliage.

Stem: Numerous, slender, upright and highly branched, smooth reddish brown bark, become furrowed and ridged with age.

Flower: Pink to white, 5-petaled.

Roots: Extensive, crown to about 18 inches deep.

Seeds: 500,000 seeds, small, easily dispersed by wind.

Other: Dependent on ground water, areas become dryer with long term occupation. A single plant can use up to 200 gallons of water per day.
