Research Task: 8327CKY.1.0
Task Manager: Pat Shafroth
Long-term, sustainable control of invasive plant species is largely dependent on successful revegetation of a site following removal/control of the invasive. Despite this, revegetation receives relatively little attention in the context of control. Current information has not been well-synthesized, and often, site-specific studies have not been conducted with methodologies that enable rigorous interpretation of results. Many researchers have hypothesized that streamflow regulation can favor tamarisk and disfavor native riparian vegetation; thus, efforts have been initiated to manage streamflow in ways that favor native taxa. However, these efforts have generally not been monitored to evaluate their efficacy. The objective of this task is to conduct research that will improve the success of land managers who are seeking to revegetate and restore xeric riparian habitats following tamarisk control, with particular focus on the Rio Grande in New Mexico and Texas. Work under this task also will support efforts to examine the efficacy of managed streamflows downstream of dams in reducing the abundance of tamarisk and increasing the abundance of native vegetation.
