Phreatophyte distributions can be used as indicators for soil type, hydraulic connectivity , and depth to groundwater . In W estern Kansas, areas with good hydraulic connectivityThe seeds, however, have a short period of viability, and must come in contact with suitable moisture within a few weeks of dispersal. Unlike obligate phreatophytes, such as willows and cottonwoods, saltcedar is a facultative phreatophyte and is often able to survive under conditions where groundwater is inaccessible.
