Phreatophyte

Phreatophyte. Evapotranspiration (ET) of groundwater may occur when the water table is close to the land surface or when phreatophytes draw water from below the water table. The Evapotranspiration Package requires the user to assign a maximum ET rate (R ETM) to each cell from which ET may occur.The maximum rate is used when the water table in a …1 Introduction. In Forest Stand Dynamics Oliver and Larson ( 1990, 1996) put forward the concept of growing space as the integration of all factors (e.g., light, water, nutrients and physical space) required for tree growth. This was a departure from the commonly accepted idea of growing space only being the physical space occupied by the crown ...The Fred Case Collection contains the minutes, memorandum and correspondence of the Phreatophyte Subcommittee from the years 1951 to 1970, as well as Bound Volumes of the minutes from 1951 to 1966.

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.The current understanding of phreatophyte sensitivity to DTG is largely derived from field measurements (e.g. Horton et al 2001, Rood et al 2011), laboratory experiments (e.g. Leffler et al 2000, Stella et al 2010), and models based on phreatophyte physiology (e.g. Tai et al 2018).The dynamics of phreatophyte vegetation are strongly coupled to those of the shallow phreatic aquifers from which phreatophytes extract water. Vegetation is able to influence the depth of the water table, which, in turn, can induce stress in vegetation.
