The lack of statistically significant differences in leaf carbon isotope ratios, average leaf mass per leaf area, flower counts per unit of canopy volume, mature seed counts, and tree population densities could be interpreted in two ways: either this desert phreatophyte is consistently able to obtain sufficient water from deep below the soil surface; or water availability might be temporarily similar upstream and downstream from berms during periods when most photosynthesis, leaf, and flower production occurs.

In relation to the latter desert area, both share halophyte and phreatophyte plants, functional types, saline soils dominance, and concentrated-dispersal model of vegetation, among others characteristics.
However, alfalfa, a deep-rooted plant, under some conditions may be considered a phreatophyte.
Furthermore, she uses too much terminology for a popular book: Archaea, aufeis, hyporheic, phreatophyte, strangmoor, ombrotrophic, anisotrophic, etc.
Prosopis, for example, is unlikely to act as a true phreatophyte at the dunes site, since the water table is so deep (Hennessy et al.
Eligible technologies are: solar, hydropower, geothermal, fuel cells that are not fossil-fueled, landfill gas and anaerobically digested waste biomass, and biomass - including fuels such as agricultural and animal waste, small diameter timber, salt cedar and other phreatophyte or woody vegetation removed from watersheds or river basins in New Mexico.
In addition to this total, roughly half a million acre-feet were lost due to phreatophyte and operational inefficiency losses.
