Delivering adequate water supplies to support expanding human enterprise while maintaining the necessary flow regimes to support desired riparian ecosystems and formally protected wildlife species that depend upon them is increasingly difficult in the arid western United States. Many riparian systems have undergone dramatic alteration over the last 50 - 100 years, exacerbating the conflicts between resource use and biodiversity protection. One of the most visible changes that is in part due to altered flow regimes is the establishment of invasive plant species in riparian ecosystems. The highest priority invasive riparian plant is the Eurasian tree/shrub, tamarisk (or saltcedar, Tamarix spp.) the third most abundant...

Executive summary: Tamarisk control and removal has become a priority of riparian ecosystem management, due in part to its potential negative impacts on stream flow and groundwater recharge. Among the most controversial, and potentially most effective tamarisk control approaches is the introduction of the tamarisk leaf beetle, Diorhabda carinulata. The beetle has spread throughout virtually the entire upper Colorado River Basin, established major populations at Lake Mead in 2012, and is now poised to expand into the lower Colorado River Basin concordant with documented evolutionary change in beetle developmental response that may enable survival in southern regions. Superimposed on this direct plant/herbivore relationship...
