Tamarisks FAQs - 3 Found
Tamarisk is now declining in abundance in some parts of its range in the West because of the release and spread of a biological control agent, a defoliating beetle. This decline because of the beetle is presenting opportunities for scientific research that examines the response of ecosystems as an invasive species declines or is controlled. Important questions that USGS scientists are working to answer include: How does water consumption along rivers change as tamarisk abundance and vigor are reduced? What plants will replace tamarisk as it dies back, and are these desirable native species or undesirable weedy species? How are wildlife populations — such as birds — responding to changes in habitat associated with vegetation change? How can land and water mangers best approach efforts to restore floodplain vegetation to achieve their objectives?
