“…Soil organic matter contents reported by Udawatta et al (2006), Kim et al (2010) and Hu et al (2015) were larger than those observed in our study (1.9-13.9 g kg -1 ). Organic matter content decreased with increasing soil depth (Table 1).…”

“…In this study, macroporosity under ALF (0.65%) and KOP (1.91%) was less than that under grass (1.5%) and tree (3.5%) buffer zones reported by Udawatta et al (2006). The macropore counts under ALF (6) and KOP (17) were smaller than those reported for the grassland in inner Mongolia (Hu et al, 2015). In general, fewer macropores and less macroporosity decrease water transmission and increase surface runoff.…”

“…Bhark & Small, 2003;Eldridge, Beecham, & Grace, 2015;Eldridge, Wang, & Ruiz-Colmenero, 2015;Gómez et al, 2015;Madsen, Chandler, & Belnap, 2008), we demonstrated substantially greater sorptivity and infiltration under the canopies of long-lived vegetation patches such as shrubs, trees, and perennial grasses than in the interspaces. These favourable abiotic conditions beneath woody canopies support greater densities of termites (Noble, Mueller, Whitford, & Pfitzner, 2009) and soil invertebrates (Chilcott, Reid, & King, 1997) that construct biopores, leading to positive feedbacks on soil physical and chemical properties, increasing infiltration (Eldridge & Freudenberger, 2005;Hu, Li, Li, & Liu, 2015;Pueyo, Moret-Fernandez, Saiz, Bueno, & Alados, 2013;Tobella et al, 2014). The magnitude of the macroporosity index for soil beneath grasses, shrubs, and trees (range 10-24) suggests that observed differences in hydrology among these microsites were largely due to the presence of macropores; large biologically produced pores that are the principal channels for conducting water.…”

“…Stem-flow deposition of material excreted by invertebrates and birds using woody plant canopies (Belsky et al, 1989) and the shedding of large volumes of litter from trees and shrubs enhance soil carbon and nitrogen pools beneath the canopies (Dean, Milton, & Jeltsch, 1999;Eldridge & Rath, 2002). These favourable abiotic conditions beneath woody canopies support greater densities of termites (Noble, Mueller, Whitford, & Pfitzner, 2009) and soil invertebrates (Chilcott, Reid, & King, 1997) that construct biopores, leading to positive feedbacks on soil physical and chemical properties, increasing infiltration (Eldridge & Freudenberger, 2005;Hu, Li, Li, & Liu, 2015;Pueyo, Moret-Fernandez, Saiz, Bueno, & Alados, 2013;Tobella et al, 2014).…”

“…In the rangelands of Inner Mongolia, China, shrub encroachment studies have been undertaken in recent years. However, none has been able to establish a clear relationship between shrub encroachment and accelerated desertification [15][16][17]. Otindag Sandy Land, located in southeastern Inner Mongolia, is characterized by serious aeolian…”
