Remedial order issued to address nontarget effects by the tamarisk beetle on the endangered Southwestern Willow Flycatcher. Lists actions required of Animal and Plant Health Inspection Service (APHIS). 

Center for Biological Diversity v. Vilsack, No. 2: 13-cv-1785-RFB-GWF (D. Nev. June 19, 2018).

Nagler et al. test the assumption that removing saltcedar (Tamarix spp.) will save water and create environments more favourable to these native species. They compared sap flux measurements of water used by native species in contrast to saltcedar, and compared soil salinity, ground water depth and soil moisture across a gradient of 200–1500 m from the river's edge on a floodplain terrace at Cibola National Wildlife Refuge (CNWR).

Glenn et al. measure transpiration and stomatal conductance to investigate the environmental constraints on an arid-zone riparian phreatophtye, saltcedar (Tamarix ramosissima and related species and hybrids), growing over a brackish aquifer along the Colorado River in the western U.S. Depth to groundwater, meteorological factors, salinity and soil hydraulic properties were compared at stress and non-stressed sites that differed in salinity of the aquifer, soil properties and water use characteristics, to identify the factors depressing water use at the stress site.
