A Bowen ratio energy balance was conducted over a Tamarix ramosissima (saltcedar) stand growing in a riparian corridor along the Virgin River in southern Nevada. Measurements in two separate years were compared and contrasted on the basis of changes in growing conditions. In 1994, a drought year, record high temperatures, dry winds, and a falling water table caused partial wilt of outer smaller...

Restoration of riparian areas is an important step toward improving water flow and water quality of the Rı́o Conchos in northern Mexico. To provide background data for restoration decisions we characterized the ecological integrity of a 40-km-long riparian corridor along the middle Rı́o Conchos. The characterization consisted of determining dominant species of trees and shrubs, structure, and qua...

The non-native Saltcedar (Tamarix ramosissima Ledeb.) and the native Honey mesquite (Prosopis Glandulosa Torr.), exist in abundance in Clark County, NV. We are using remote sensing to measure changes in distribution and abundance of these species. We collected six strips of 1m-resolution SpecTIR hyperspectral images in Clark County on May, 2005. SpecTIR has 227 spectral bands ranging from 0.45 ...
