Phreatophyte.

Phreatophyte transpiration consumes groundwater and causes diurnal fluctuations of groundwater levels . On the other hand, surface water is scarce, and groundwater is often the only reliable water resource for socio-economic development in arid regions . Irrigation water for crops is usually provided by the abstraction of groundwater.Our analysis of groundwater level data, soil profiles, and vegetation characteristics at two typical phreatophyte-dominated sites (Tamarix ramosissima and Populus euphratica) located in hyper-arid desert environments in northwestern China indicates that groundwater evapotranspiration is an important factor that controls …John Scheuring, Conservation Committee Chairman for the Arizona Native Plant Society, appeared on TV-KOLD to talk about this.

We also found a physiological threshold at ...

phreatophyte zones within the DVHA were delineated to include only those areas containing phreatophytic vegetation; but vegetation in those zones includes non-phreatophytic grasses, forbs and shrubs as well, particularly near the upper phreatophyte zone boundaries. Vegetation of all types can respond to significant

Phreatophytes are plants that depend for their water supply upon ground water that lies within reach of their roots. Although not confined to the arid regions of the Western United States, their occurrence there is more common, more spectacular, and, because of their effect on water supply, more important than it is in humid and subhumid regions.
