Morpho-anatomically, for instance, the …Groundwater is a main water source for phreatophytes in arid and semiarid areas. Evapotranspiration partitioning shows that transpiration accounts for the majority of evapotranspiration [4,5].Over the past few decades, vegetation coverage has displayed a large increase because of the multiple ecological restoration programs including the …Adaptations of Desert Annuals. Desert annuals are plants that adapt to desert conditions by completing their lifecycle when there is sparse rainfall, and then all the parts of the plant die. The desert annuals grow, the flower produces seeds and then dies. The seeds lie dormant until the conditions are favorable for growth.Butler et al. showed that the major controls on phreatophyte-induced groundwater fluctuations depend on weather conditions, plant density, and species type, as well as on the specific yield of the sediments near the water table. These advances motivated our study by providing techniques to appropriately use the White method in …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.1. Soil characteristics influence plant communities in part through water relations. Hypothetically, finer textured soils in arid climates should be associated with more negative plant and soil water potentials during drought, greater resistance of xylem to cavitation, and shallower root systems than coarse soils.Diurnal water table fluctuation is considered the evidence and indicator of groundwater evapotranspiration by phreatophytes in arid areas. Based on the ...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.Issues Concerning Phreatophyte Clearing, Revegetation, and Water Savings Along the Gila River, Arizona.
