Landslides caused many ecological processes at landscape to local scales, including the ecological succession processes. The landslides geological characteristics and their management as physical risks are truly documented but the ecological processes that are caused by landslides and their relations to efforts to restore stability to unstable slopes, have not been well studied. In this study, soil mechanical, physical and chemical properties and herbaceous biodiversity of stabilized sliding area in Kheyrud Forest were compared to adjacent non-slide area. To study the properties of soil and herbaceous biodiversity in two areas were used 2×2 m plots. Past software was used to calculate biodiversity indexes and independent t-test in spss was used in order to compare biodiversity indexed and soil. No significant difference was found between soil chemical characteristics and herbaceous diversity in two areas. Results of soil mechanical properties showed that soil of the areas is fine-grained and clay loam (CL). Results generally showed that stabilized sliding area has returned to the original state before the landslide in terms of soil mechanical, physical and chemical properties after about two decades. It seems that in such areas it can be expected that the conditions of biodiversity of the grass are meaningless, and finally, by closing or redirecting the marginal slopes, some soil characteristics can be restored to the proper condition.
