Water use by the introduced shrub Tamarix ramosissima and three co-occurring, native phreatophytes was measured in the lower Virgin River floodplain (southern Nevada) using the stem-heat-balance method. During the 1993 growing season, measurements were conducted on Tamarix in a closed, monospecific stand and in a mixed community with the native species Pluchea sericea, Prosopis pubescens, and Salix exigua. Our objectives were (1) to determine whether leaf-area-based water use of Tamarix is higher than that of co-occurring native riparian taxa, (2) to assess the role of Tamarix stand leaf area index (LAI, leaf area per unit ground area) on Tamarix water loss, and (3) to verify whether Tamarix is capable of using large amounts of water under the extreme evaporative demands that characterize arid environments. Leaf-area-based sap flow rates were comparable in the four species despite large differences in individual leaf area and total water loss. Daily water use of Tamarix (in grams per day) weighted by the daily potential evapotranspirati-on (PET) increased linearly with the total leaf area per plant, suggesting that water uptake was sufficient to compensate for water loss at the leaf level, even during times of extreme atmospheric water demand. Under high PET, maximum sap flow rates of Tamarix on a leafarea basis were significantly higher at locations where Tamarix LAI was lower, indicating that highly transpiring Tamarix stands may reduce leaf-level evaporative demand. However, daily estimates of transpiration of dense Tamarix stands (LAI up to 3.5 m2/m2) in our study site exceeded PET by a factor ranging from 1.6 to 2.0, which confirms that mature Tamarix stands can lose very high quantities of water due to the maintenance of high leaf area. Results from this and other studies demonstrate that, at least under moderate to high water tables, key variables controlling water use by riparian stands include structural characteristics such as LAI and density. Management practices aimed at conserving water should be geared towards avoiding the development of dense Tamarix thickets along arid water courses, particularly if it is confirmed that these tend to attain higher LAI than native riparian communities.

Evapotranspiration and its main controlling mechanism over the desert riparian forests in the lower Tarim River Basin

“…The larger LAI, the higher ET. The same pattern was observed in arid regions of southwest USA (Sala et al, 1996). We analyzed the relationship of LAI and ET/ET 0 in GLE and LSP for both Tamarix stand and Populus stand.…”

Groundwater-dependent ecosystems: recent insights from satellite and field-based studies

“…Of further risk to riparian GDEs and agriculture, groundwater extraction and land use change threaten riparian ecosystems (Scott et al, 1999;Nippert et al, 2010;Pert et al, 2010). Thus, many studies have been undertaken over several decades to investigate the water use of GDEs in south-western North America (van Hylckama, 1970;Gay and Fritschen, 1979;Sala et al, 1996;Devitt et al, 1998;Goodrich et al, 2000a;Cleverly et al, 2002;Scott et al, 2004;Nagler et al, 2005b). Sunlight is plentiful in the south-western USA; thus, riparian GDEs are strong carbon sinks (Kochendorfer et al, 2011).…”

Multiple states in river and lake ecosystems

“…Local reductions in the groundwater level may be caused by species that effectively exploit groundwater. Saltcedar can reach a lower water table and use more water per unit sapwood than several native species (Sala et al 1996;Cleverly et al 1997;Horton & Clark 2001). Shafroth et al (2000) found that saltcedar saplings were significantly less vulnerable than indigenous species to groundwater depletion.…”
