man of the Phreatophyte Subcommittee, was instrumental in focusing attention on the phreatophyte problem in the Southwest and in preserving data concerning phreatophytes in the minutes of the subcommittee. He was one of the first to study the problem of saltcedars and to obtain data on their use of ground water.
Responses of phreatophyte transpiration to falling water table in hyper-arid and arid regions, Northwest China. 2021, China Geology. Show abstract. Quantitative assessment of the impact of groundwater depletion on phreatophytes in (hyper-) arid regions is key to sustainable groundwater management. However, a parsimonious model for …Riparian zones act as ecological engineers through stream bank stabilization, pollutant buffering, energy provision to food webs, and groundwater recharge. In the ongoing situation of declining river water quality and global environmental changes, an integrated strategy involving aspects of riparian zone monitoring and management is essential for …Phreatophyte Removal The San Juan Soil and Water Conservation District aims to protect and reduce wildfire risk by removing non-native Russian olive and Salt Cedar infestations in identified high-priority areas. The project will also undertake native plant and tree restoration activities to help restore riparian habitat and improveEvapotranspiration rates and the ground water component of evapotranspiration at a site in Colorado's San Luis Valley that is dominated by shrubby phreatophytes (greasewood and rabbitbrush) were compared before and after a water table drawdown. Evapotranspiration (ET) rates at the site were first measured in 1985-1987 (pre-drawdown) when the mean water table depth was 0.92 m.A phreatophyte is one that absorbs its water from a constant source on the ground. They can usually be found along streams where there is a steady flow of surface or groundwater in areas where the water table is near the surface.
This study originated with the objective of parameterizing riparian evapotranspiration (ET) in the water budget of the Middle Rio Grande. We hypothesized that flooding and invasions of non-native species would strongly impact ecosystem water use. Our objectives were to measure and compare water use of native (Rio Grande cottonwood, Populus deltoides ssp. wizleni) and non-native (saltcedar ...
Mesquite is a typical phreatophyte that extends its roots rapidly into deep aquifers . Because mesquite can use groundwater through deep tap roots, this species can survive in arid environments and thus efficiently compete with many native plant species .Xerophyte and Phreatophyte. On a separate sheet of paper, tell how they are the same and how they are different. Desert Flower Power By Alice Knisley Matthias This poem is about plants that have adapted to live in dry climates. In the case of plants, thrive means to be extremely healthy and able to grow easily; to be successful or prosper.
The well-known White (1932) method based on diurnal water table observations has been widely applied to estimate groundwater evapotranspiration (ETG) from phreatophyte vegetation.utilization of a desert phreatophyte, Alhagi sparsifolia. The study was published in Frontiers in Plant Science on June 7. The plant was grown at groundwater depths of 2.5, 4.5, and 11.0 mFroend, R.H.; Drake, P.L. 2006: Defining phreatophyte response to reduced water availability: preliminary investigations on the use of xylem cavitation vulnerability in Banksia woodland species Australian Journal of Botany 54(2): 173-179As such, remote sensing appli- cations for spatially distributing flux tower estimates of ET and groundwater ET (ETg) across phreatophyte areas are becoming ...
As a result, groundwater use by phreatophyte communities may vary both spatially and temporally in response to seasonal or long-term changes in growing season precipitation. I conducted a two-year rainfall manipulation experiment in the San Luis Valley, Colorado to investigate the responses of four common native phreatophyte species to ambient ...

Results: Ziziphus lotus behaves as a facultative or partial phreatophyte with extreme anisohydric stomatal regulation. However, as DTGW increased, Z. lotus (1) reduced the use of groundwater, (2) reduced total water uptake, and (3) limited transpiration water loss while increasing water-use efficiency. We also found a physiological threshold at ...riparian phreatophyte. K. R. ... bivory in an invasive phreatophyte that currently dominates riparian areas throughout the western USA and northern. Mexico.The vertical root distribution of riparian vegetation plays a relevant role in soil water balance, in the partition of water fluxes into evaporation and transpiration, in the biogeochemistry of hyporheic corridors, in river morphodynamics evolution, and in bioengineering applications. The aim of this work is to assess the effect of the stochastic variability of the river level on the root ...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. ACKNOWLEDGMENTSIn addition, comparison of the tree inventories performed in the summers of 2002 and 2005 reveal a 20-25% mortality rate over the study period, with an additional 20% of trees under severe water stress. The native phreatophytes appear to be having difficulty keeping pace with the falling water table, leading to severe stress and a high rate of ...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.The family Lamiaceae comprises around 236 genera and 7173 species distributed worldwide ( Stevens, 2012 ). The genus Gmelina includes 38 species of trees occurring in tropical Asia, Australia and New Guinea ( Flora of China Editorial Committee, 2016 ). Gmelina is related to the large genus Vitex, which also includes several timber trees.We investigated hydraulic constraints on water uptake by velvet mesquite (Prosopis velutina Woot.) at a site with sandy-loam soil and at a site with loamy-clay soil in southeastern Arizona, USA.The characteristics of phreatophyte vegetation vary across the riparian zone, and ground-water consumption varies accordingly. Data collected at the LRS in mid-summer of 2003 demonstrate that the amplitudes of the diurnal water-table fluctuations clearly depend on vegetation density, type, and size.

To assess the long-term response of the vegetation, we mirror aspects of the Phreatophyte Project by defining the spatial extent of our analysis using boundaries of areas included in the initial project. For the Phreatophyte Project, the floodplain was divided into four subreaches: 1, 2a, 2, and 3 (Culler et al., 1982). Furthermore, we included ...This study employed ground and remote sensing methods to monitor the effects of grazing on leaf area index (LAI), fractional cover (f(c)) and evapotranspiration (ET) of a desert phreatophyte community over an 11 year period at a former uranium mill site on the Colorado Plateau, U.S. Nitrate, ammonium and sulfate are migrating away from the mill site in a shallow alluvial aquifer.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.
