Currently, however, few models can fully depict the complex water use strategies of phreatophytes. A special group of desert plants, known as phreatophytes, have long roots that reach deep into soil to tap underground water tables. Mesquite trees ( Prosopis species), including screwbean mesquite, honey mesquite, and velvet mesquite, belong to this group. The roots of some mesquite trees have measured up to 80 feet long.

Nov 3, 2021 · Phreatophytes are deep-rooted plants that reach groundwater and are widely distributed in arid and semiarid areas around the world.
