Abstract
Grazing by sheep and goats has a significant impact on species composition, plant biomass, and soil chemical, physical and bacterial properties in the cool semi-desert highlands of Asir, Saudi Arabia. The comparison between grazed and protected flats and hills revealed that the protected flats and hills maintain higher species diversity, plant biomass, plant heights, soil carbonates, cation exchange capacity, and electrical conductivity; but a relatively lower soil water content, organic matter, total nitrogen, and total number of bacteria.
