Control Methods


Control Methods

Management of non-native phreatophytes consists of five components – planning with inventory/mapping, control, revegetation, monitoring, and maintenance. Without all five components it is unlikely that tamarisk control projects will be successful over the long term. Successful management also depends on changing the approaches based on experience and the availability of newer technologies (adaptive management).

Tamarisk can be managed using successional weed management techniques, including chemical, mechanical, and biological techniques. Due to its ability to re-grow from root crown buds, mechanical removal of above ground biomass must be followed by root raking or herbicide stump treatment. Tamarisk will also re-grow from the roots if burned. All of the following tamarisk control techniques are appropriate, but each must be selected based on local conditions; i.e., Integrated Pest Management. Integrated Pest Management or IPM is also known as the “toolbox” from which land managers select their tools for a job. It includes prevention, cultural management (land stewardship), mechanical or physical removal, biological control, herbicide treatments, and revegetation techniques. A comparison of each major control technology describes effectiveness, costs, impacts, and applicability. It should be noted that there are many different hybrids of these technologies that fall within the general understanding of tamarisk control; and actual costs and applicability may vary for each site. Wherever herbicides are identified as a component of a control option, the product identified is the one most widely used and the application rate on the product label should be followed
