U.S. Geological Survey. 2730 N. Deer Run Road. Carson City, Nevada 89701. Declining water levels and reduced natural discharge at springs, seeps, and phreatophyte areas primarily are the result of decades of groundwater development in the Death Valley regional flow system, in Nevada and California. A calibrated groundwater-flow model was used ... Evapotranspiration 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.Calligonum mongolicum is a phreatophyte playing an important role in sand dune fixation, but little is known about its responses to drought and P fertilization.

Compared to coast redwoods which usually grow to a height of 379 feet (116 meters), oak trees stay in the category of middle-height trees. However, contrary to redwood, their branches can spread wide in length. Therefore, they are also considered shrubs.

In Western Kansas, the two dominant phreatophyte tree species are cottonwood (populous deltoids) and salt cedar (Tamarisk). Cottonwood trees are typically found in flood plains because they require floods to germinate ( Nagler et al., 2005). Cottonwoods have a maximum rooting depth of 2.6m (Canadell et al., 1996), their roots do not penetrate ...
