Phreatophytes are deeply rooted plants that use groundwater to fulfill parts of their water needs (Thomas, 2014).

From an ecological point of view, Tamarix species are phreatophytes, which form dense groves growing in ravines, river banks and also in saline soils, mostly located in arid and semi-arid zones.
They suggested that 'blue oaks should be considered obligate phreatophytes,' that is, water-loving plants similar to, for example, riverbank willows.

These diatomites, albeit bare of any perennial vegetation cover, exude small springs of highly saline waters and therefore play a determinant role in the distribution of the neighbouring vegetation almost entirely made of halophytes and phreatophytes.
The water table allows perennial vegetation to grow, sometimes even with trees, since many desert trees are phreatophytes, meaning they grow precisely where the water table is accessible to their deep root systems.

Tamarix has been described as possessing inherently low water use efficiency (Anderson 1982), a characterization that has also been applied to aridland phreatophytes in general (Smith and Nobel 1986).
Both models indicate a benefit from large, current-year floods, underscoring the sensitivity of dryland floodplain phreatophytes to low soil moisture availability (Gazal et al.
