Description :
This study addressed the effect of the dwarf shrub Sarcopoterium spinosum on soil properties, soil moisture and vegetation characteristics (plant density and richness) in a semi-arid ecosystem. Vegetation characteristics and soil sample data were obtained from 3 areas: 1) beneath the S. spinosum patch, 2) between the patches and 3) from the open area. The results showed that the area beneath S. spinosum had significantly higher soil moisture content, organic matter, available ammonium, nitrate, and phosphorus compared to the areas between shrubs and open areas. The results also showed that the total plant density and richness decreased significantly beneath the shrub canopy compared to the areas between shrubs and open areas. The results indicated that S. spinosum creates habitat heterogeneity by modifying the area beneath its canopy and influencing the community structure. This role should be considered in rangeland management.
