1 Introduction. A phreatophyte, which means “well plant” in Greek, is a deep-rooted plant that has the ability to obtain a perennial supply of water from the phreatic zone (or saturated zone) and/or the capillary fringe above the phreatic zone in the soil profile (Meinzer, 1927).Extensive reports indicated that phreatophytic vegetation is widely …Groundwater flux is important for Classes II and III GDEs because it sustains water uptake by vegetation (Shafroth et al. 2000).Reduced groundwater pressure and flux cause reduced groundwater discharge and subsequently reduced surface water availability to wetlands and GDEs that depend on base flow and springs (Zektser et al. 2005).In estuary or coastal areas reduced groundwater flux leads to ...

The dynamics of phreatophyte vegetation are strongly coupled to those of the shallow phreatic aquifers from which phreatophytes extract water. Vegetation is able to influence the depth of the water table, which, in turn, can induce stress in vegetation. These interactions are likely to affect the composition and structure of phreatophyte plant ...
