“…Enhanced levels of infiltration surrounding the canopy are a defining feature of arid zone shrub communities (e.g., Bhark and Small, 2003). Soil porosity is greater and macropores are present adjacent to the roots and stem of woody plants, which also have well-developed tap roots allowing the plants to access water from greater depths (Archer et al, 2002). While the extent of infiltration is known to decline with increasing distance from the canopy, the exact nature of this decline is largely unknown for most woody species, and has been studied in only a few arid zone shrubs (e.g., Atriplex spp., Dunkerley, 2000).…”

“…Moreover, shrubs act as a physical barrier that moderates overland flow velocity and continuity (Sanchez and Puigdefabregas, 1994); consequently, they trap soil and litter (Bergkamp, 1998;Shachak et al, 1998), forming soil mounds (Rostango and del Valle., 1988;Parsons et al, 1992) and thereby changing the surface microtopography as well as the soil texture and bulk density (Van Haveren, 1983;Trimble and Mendel 1995;Stavi et al, 2008bStavi et al, , 2009). The combined physical, chemical and biological effects of shrub roots (Archer et al, 2002) and soil biological activity (Garner and Steinberger, 1989) improve soil organic matter content and structure (Oades, 1984;Sarah and Rodeh, 2004;Sarah, 2006), which reduces bulk density even more (Dunkerley and Brown, 1995), and creates macropores, in which water flows vertically at relative high rates (Bromley et al, 1997). Furthermore, in the study area the deepest soil was found beneath the shrubs.…”

“…Previous studies of shrub and grass root systems at these two sites have shown that the shrub root systems form larger, deeper macro-pores than grass roots systems (Archer et al, 2002) and, hence, increase infiltration of water to deeper depths. This would lower the soil water potential at all depths under shrubs (Fig.…”
