  A study has been carried out on the effect of roots on slope stability, in particular for tea (Thea sinensis L.). The study area was located in Roudsar Township, in Gilan State of N Iran. Some parts of this area have been planted with tea. Soil samples with and without roots of the mentioned species were taken, on an area of approximately 15 ha large, for testing in the Laboratory. Soil shear tests were carried out on these samples and the Factor of Safety (FS) was calculated. Results showed that the FS was increased in soils with roots present. The global slope FS was then determined using Bishop’s method. We calculated FS in order to protect slopes where the gradient exceeds 25%. In this case study minimum FS which corresponds to Thea sinensis L. vegetation with 20-40% crown cover, a soil internal friction angle of 15° and a slope angle of 15°. When soil internal friction angle equals 20° and slope angle is more than 23°, slope stability can not be increased by Tea vegetation species.
