In the northern Negev region of Israel, the AA. examined the soil properties associated with flock trampling routes and rock fragment clusters, as well as those associated with the remainder of the intershrub area and shrub patches. Moisture content, organic carbon content, bulk density and calcium carbonate content of the soil were determined for these 4 types of cover, inside and outside long-term grazing enclosures. Grazing increased the spatial heterogeneity of the soil properties examined via the creation of a network of trampling routes on the hillsides. It is important to recognize trampling routes as a separate midrohabitat within the intershrub area. The soil properties of the shrub patches and the trampling routes lie at opposite ends of the scale, and those of the intershrub areas fall between them
