“…The data indicate a redistribution of N from intercanopy to canopy soils by juniper. These results agree with other studies in pinyon-juniper woodlands showing accumulations of C and N in soils under juniper canopies during woodland development (Barth, 1980;Doescher et al, 1987;Klemmedson & Tiedemann, 2000).…”

“…With regard to the effectiveness of canopy cover on local soil properties, previous studies have reported that the extent of enrichment of soil C and nutrients under tree canopies increased with tree age or size (Barth 1980;Bernhard-Reversat 1982;Klemmedson and Tiedemann 2000;Tiedemann and Klemmedson 2000;Ludwig et al 2004). Higher enrichment of C and nutrients beneath the canopy with increased tree size was probably due to increased primary production or litter supply per unit area (Bernhard-Reversat 1982;Hook et al 1991;Tiedemann and Klemmedson 2000) and longer occupancy of a particular area (Hirobe et al 2001).…”

“…compared with surrounding soils. Several previous studies have demonstrated that for soil nutrients under tree canopies, the extent of enrichment is correlated with canopy size or tree age (Barth 1980;BernhardReversat 1982;Klemmedson and Tiedemann 2000;Ludwig et al 2004). Because enrichment of soil nutrients in mounds is expected to intensify under larger canopies, the effects of canopy size should be considered when examining the effects of vegetation mounds on local soil properties.…”

Effects of Caragana microphylla patch and its canopy size on “islands of fertility” in a Mongolian grassland ecosystem

et al. 2010

In arid and semiarid regions, variations in ''islands of fertility'' accompanied by discontinuous vegetation is frequently observed. However, the effects of vegetation patches on soil, including the influence of canopy size, are not fully understood, particularly under conditions of severe grazing. We examined the effects of patches of mound-forming shrub, Caragana microphylla, and the plant's canopy size on these islands of fertility in a heavily grazed Mongolian grassland. In 11 patches with various canopy sizes (32.5-180 cm in diameter), we compared the chemical properties of soils among three microsites: Mound, Below, and Around, which were inside, below, and outside of C. microphylla mounds, respectively. Total carbon (C) and most essential elements for the plants were more concentrated in Mound, but total nitrogen (N) and nonlimiting elements, such as exchangeable sodium (Na), did not significantly differ among microsites. Larger canopies more strongly affected the enrichment of total C and most essential elements, including total N, in Mound. These results suggest that C. microphylla patches substantially enrich total C and most essential elements and that the extent of enrichment was intensified with canopy size. However, under severe grazing, total N may be relatively more affected by the redistribution of resources through grazing, particularly when the canopy size is small.

“…Soil beneath woody plant canopies typically is more fertile than the surrounding grassland in semi-arid environments (Ebersohn & Lucas 1965;Charreau & Vidal 1966;Radwanski & Wickens 1967;Singh & Lal 1969;Tiedemann & Klemmedson 1973, 1977Charley & West 1975;Aggarwal et al 1976;Barth 1980;Bernhard-Reversat 1982;Belsky et aL 1989;McPherson et al 1991). Shrub canopies create 'islands of fertility' (Garcia-Moya & McKell 1970) beneath the canopy by concentrating soil nutrients and depositing organic material.…”

Effects of Quercus emoryi on herbaceous vegetation in a semi-arid savanna

Ten trees (5-70 m 2 canopy area) were selected to determine effects of tree size (crown area) on herbaceous species composition and biomass in a Quercus emoryi savanna in southeastern Arizona. Consistent with most studies in temperate savannas, herbaceous biomass was reduced beneath the canopy relative to grassland areas. However, tree size appeared to exert no influence over herbaceous biomass. In contrast to most temperate savannas, Q. emoryi trees did not affect distribution of herbaceous species.
