註釋Saltcedar was introduced into the United States from Eurasia during the late eighteenth century and has spread throughout the southwestern United States. Saltcedar is a facultative phreatophyte, evapotranspiring as much as 11,101 cubic meters (9 acre-feet) of water per 0.4 ha (1 acre) per year. Saltcedar communities are much less valuable to wildlife than are native riparian plant communities. A manager must assess the saltcedar problem and possible solutions before starting control, and should subsequently evaluate the results. For control, saltcedar must be killed by root plowing, herbicide application, or inundation, and prevented from reinvading. The selection of other species to be planted when revegetating is determined by the soil and groundwater salinity, soil texture, and water table depth. Plantings should be arranged for maximum wildlife benefit. Three case studies show that saltcedar can be controlled successfully.
