Abstract: To verify whether or not a pulling effect exists in the root system of Petrocarya fraxinifolia in the Roudsar, North Iran and to study the importance and size of this effect, a direct in situ test was led at a site in the Chaboksar Forests. The results from the site showed that, in the surface soil (0-30 cm), Side roots can provide a pull force of up to 522-788 N (Newtons) over a vertical cross-section area of 20-50 cm2, or an enhance in the pulling stability of the rooted soil by about 44.7%. The test results suggest that, together with the Petrocarya fraxinifolia vertical roots, which keep the little depth rooted soil zone to the deep and more stable soil mass, the side roots of the Petrocarya, with their pulling effect, are able to make less against little depth instability in the forest slopes, such as little depth slide, to a certain degree.
