Abstract : Overgrazing and soil degradation are widespread in Saudi Arabia particularly, where sheep and goats are free to roam. These impacts have long been recognised and at Sarawat Mountains,some protection was achieved locally by the establishment of Himas, small protected areas belonging to the local village or tribe. This paper seeks to demonstrate this by analysing the differences in soil surface conditions and vegetation species richness in Hima Al-Foga, south east of Al-Baha dist. Soil particle sizes and the orientation of surface stones were measured along two transectsinside each site. It was found that soil particle size was generally finer in protected area. Fabric analyses of the surface stones showed a fairly random pattern inside the protected area, suggesting little disturbance whereas in the overgrazed rangeland the stones tended to be oriented down slope, their mobility and orientation having been affected by repeated disturbance by sheet flow. A survey of the vegetation Hima Al-Foga showed that there were 20 plant species growing inside the Hima of which 16 plant species were palatable to sheep and goats. This contrasts markedly with the overgrazed range outside the Hima. Here 15 species of vegetation were found of which 13 plant species were unpalatable.It is concluded that the Hima system of range management had a very positive impact on soil condition and vegetation richness in studied area.
