Salt cedar tamarix spp essay

Tamarix is the old Latin name; ramosissima means "most densely branched". The leaves are alternate, small, scalelike, a few millimeters long, sessile, broadest basally and more or less clasping or sheathing. The flowers are about 1.

The herbicides triclopyr e. Anderson [18] studied the Apache cicada in a native riparian community and a tamarisk stand along the lower Colorado River. If the water table is less than 5 feet 1.

If the water table is less than 5 feet 1. Herbicides used at aquatic sites include Arsenal and Habitat. Management Mechanical management methods have been shown to be unsuccessful due to the Salt cedar tamarix spp essay ability to re-grow from cuttings or roots alone.

It is long-lived years and grows to 6 to 26 feet m tall. In some cases, tamarisk probably replaces rather than displaces native riparian vegetation that has been destroyed by human activities.

He found that although cicadas were abundant in both communities, the insects emerged later in the native, cottonwood and willow-dominated communities when migrating and nesting birds were present. It appears that saltcedar is a pioneer or colonizing species that establishes on freshly exposed alluvium, sand and gravel bars, and streambanks or other floodplains after disturbance.

Tamarisk is a relatively long-lived plant that can tolerate a wide range of environmental conditions once established. This treatment appears to be most effective in the fall when plants are translocating materials to their roots.

Saltcedars have successfully invaded nearly every drainage system in arid and semi-arid areas in the southwestern United States and occupy over 1 million acres. Rapid growth can allow the invading plant to reproduce within the first year.

The ramosissima species can be distinguished from other Tamarix by the 5 toothed sepals. Seeds are easily dispersed by wind and water, and severed stems and shoots of saltcedar readily root in moist soil. Most of what is called T. They have become so abundant on islands of the Gulf that much of the native vegetation has been eliminated.

The branchlets are slender with minute, appressed scaly leaves. Crowding out native vegetation There is little doubt that tamarisk can crowd out native riparian and wetland vegetation.

Tamarisk can be controlled by five principal methods: Ideal conditions for first-year survival are saturated soil during the first few weeks of life, a high water table, and open sunny ground with little competition from other plants. However, it can possibly be controlled through a combination of methods.

The deep pink to almost white flowers crowd in many slender spikes, forming dense masses at the top of the branches. In fact, black chinned hummingbirds Archilocus alexandri nested only in tamarisk-dominated habitats along the Colorado in the Grand Canyon Brown This change in temporal availability of this key food resource may help explain the low abundance of breeding birds in tamarisk communities.

Biocontrol Research has indicated that approximately a dozen insect species are available that might be useful in fighting saltcedar, but none are presently available. Animal Impact Although it can provide nesting area for some species, avian density and diversity decreases dramatically when saltcedar is present.

The most widespread species are T. The seedlings of this species grow more slowly than many native riparian plant species and it is highly susceptible to shading Carpenter, Bulldozing, followed by root-plowing is successful, consistent and effective when used on large thickets of established Tamarix ramosissima.

The seedpods are pinkish red to greenish yellow, and will break into 3 to 5 parts when mature. It can replace or displace native woody species, such as cottonwood, willow and mesquite, which occupy similar habitats, especially when timing and amount of peak water discharge, salinity, temperature, and substrate texture have been altered by human activities.

Alternatively, it may be more cost-effective to kill all woody plants at a site and replant desirable species afterward.

Plants are deciduous, although sometimes leaves persist through mild winters. The basal bark treatment involves applying the herbicide mixture to the lower 18 inches of the plant clear to the ground.

The flowers are small, short-pediceled or sessile with four or five pink or white petals inserted under a staminal disk.

Saltcedar can inhabit the following types of ecosystems:. Appendix A Tamarisk Tamarix spp.
