Phreatophyte - The short-term and long-term ecological responses of phreatophyte communities to water table change have rarely been investigated. Phreatophytes respond in a variety of ways to water table decline, but both the magnitude and rate of water table decline can affect vegetation, and thus ET response.

 
Phreatophyte. a plant with an extremely deep root system that uses groundwater as its source of moisture. A classical example is the date palm ( Phoenix dactylifera ), which grows on oases in the Sahara and the Arabian Peninsula. (An ancient Arabic proverb says that the date palm has its head in fire and its feet in water.). Ku swim

A phreatophyte is a deep-rooted plant that obtains a significant portion of the water that it needs from the phreatic zone or the capillary fringe above the phreatic zone. Phreatophytes are plants that are supplied with surface water and often have their roots constantly in touch with moisture. A phreatophyte is one that absorbs its water from ...Chaparral is a general term that applies to various types of brushland found in southern California and the southwestern United States. Plants such as manzanita, ceanothus, chamise and scrub oak, along with other grasses and forbs, are examples of typical chaparral flora. This community contains the most flammable type of vegetation found in ...A phreatophyte is a deep-rooted plant that obtains a significant portion of the water that it needs from the phreatic zone (zone of saturation) or the capillary fringe above the phreatic zone. Phreatophytes are plants that are supplied with surface water and often have their roots constantly in touch with moisture. A phreatophyte is one that absorbs its water from a constant source on the ground.The results indicate that groundwater recharge accounts for only 21.16% of the precipitation, while 72.54% is lost in the form of evapotranspiration. The annual-lumped groundwater recharge rate decreases in the order of cropland, grassland, urban land, and forest. Land use change has resulted in a decrease of 4 × 106 m3 of yearly groundwater ...Quantitative assessment of the impact of groundwater depletion on phreatophytes in (hyper-) arid regions is key to sustainable groundwater management.

Phreatophytes are deep-rooted trees and shrubs that obtain a dependable water supply from the "phreatic surface" (Meinzer 1927), i.e., from the saturated water table, and thus maintain water status that is largely independent of soil water derived from incident precipitation. Arborescent phreatophytes have tap roots that can extend to a ...The family Lamiaceae comprises around 236 genera and 7173 species distributed worldwide ( Stevens, 2012 ).

Phreatophytes of RobinsonPhreatophytes 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.
