Phreatophytes in (hyper-) arid zones usually grow in riparian zones where water tables are very shallow (Sun ZY et al., 2015). Within the range of 0.3–1.0 m, transpiration is nearly constant due to the capillary rise (Shah N et al., 2007). It means that there will be less impact on transpiration following a water table decline within this range.The areas with extensive dunes support a distinctive community of shrubby trees with extensive root systems that are adapted to the shifting, unstable substrates. The low dunes support a shrubby vegetation, while the areas at the base of dunes supports Phreatophytes, which are plants with roots that can reach into sub-surface water.

Oct 3, 2016 · Phreatophytes, such as grasses, shrubs, or trees, can specifically be installed to affect the site groundwater hydrology and to take up contaminants dissolved in groundwater (Landmeyer, 2001).

phreatophyte ( plural phreatophytes ) ( biology) Any plant, typically living in deserts, that obtains its water from long taproots that reach the water table.Groundwater-dependent ecosystems are ecosystems that are supported by groundwater. These places include springs and seeps, caves and karst systems, and deep-rooted plant communities (phreatophytes). In many cases, rivers, wetlands, and lakes are also included. Where groundwater meets the surface, a unique community of plants and animals ... These plants have been called phreatophytes. 1 The term is obtained from two Greek roots and means a "well plant."

shrubs are not phreatophytes and eddy covariance (EC) measurements showed consistently higher C sequestration in a 4-year burn watershed (woody-encroached) than in an annual-burn watershed (grass), potentially because C3 woody vegetation has greater access to deeper water than C4 grasses [16].

Phreatophytes or groundwater plants are taxa that occur exclusively in or are largely limited to the sphere of influence of the water table (Londo, 1988). Hence, a concise vegetation (phreatophytes) mapping can be performed as an indication of the occurrence of groundwater discharge in the valleys. These results can be used for …Dryland river basins frequently support both irrigated agriculture and riparian vegetation and remote sensing methods are needed to monitor water use by both crops and natural vegetation in irrigation districts.
