These are supplied with water ...supply, to include the "phreatophyte problem". In fact, it was pointed out by Douglas (1954, p. 8-12) that the word "phreato phyte" is becoming a term that the laymen find convenient for designating a group of destructive enemies that formerly were regarded merely as nuisances. ACKNOWLEDGMENTSAs such, phreatophytes have the ability to extract a large volume of water from groundwater. Removal of phreatophytic vegetation from riparian areas for water ...A small number of species called phreatophytes have root systems capable of reaching deep into groundwater supplies. That helps them survive in arid and semiarid climates …As a facultative phreatophyte and halophyte, tamarisk has a competitive advantage over native, obligate phreatophytes (e.g. cottonwood and willow) in areas where salinities are elevated or water tables depressed, conditions characteristic of disturbed riparian environments [44,115,165,170,181,211,212]. 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 ...Most significantly, species from high rainfall environments (E. obliqua, E. rubida) and the phreatophyte (E. camaldulensis) had lower osmotic potential under water deficit via accumulation of cellular osmotica (osmotic adjustment). In contrast, species from low rainfall environments (E. cladocalyx, E. polyanthemos and E. tricarpa) had lower ...phreatophyte the writer did not imply that this group should find a separate place in the old classification, but rather believed that it would overlap some of the other groups. The term " helophyte " has been used for marsh plants, which are more or less intermedi ate between hydrophytes and nresophytes, but this term could not be used to ...Nutrients are vital for plant subsistence and growth in nutrient-poor and arid ecosystems. The deep roots of phreatophytic plants are necessary to access groundwater, which is the major source of nutrients for phreatophytes in an arid desert ecosystem. However, the mechanisms through which changes in groundwater depth affect nutrient cycles of phreatophytic plants are still poorly understood ...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.)The U.S. Bureau of Reclamation began a phreatophyte clearing and control program in the bottom land of the Acme-Artesia reach of the Pecos River in March 1967. The initial cutting of 19,000 acres of saltcedar trees, the dominant phreatophyte in the area, was completed in May 1969. Saltcedar regrowth continued each year until July 1975, when root plowing eradicated most of the regrowth.This facultative phreatophyte tolerates moderately saline conditions or xeric, nonsaline upland sites with shallow water tables.
