Phreatophytes are plants that depend on ground water within reach of their roots for their water supply. More than 70 species of plants have been classified as phreatophytes (Kobinson, 1958, p. 1). The consumptive use of water differs greatly among species, but, in general, phreatophytes use more water than other 14.

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.Jul 1, 2014 · Abstract. Phreatophytes are plants with temporary or permanent access to ground water. Despite distinct interspecific differences, many phreatophytes share the following traits: 1) rapid vertical ... Phreatophytes.
