Existing coarse materials produced during surface erosion in the marl watershed basins in tributary beds and impermeable subsurface layers (marl layers) lead to produce a subsurface flow. This subsurface flow can be used in order to develop vegetation cover in order to made the biological stabilization of tributary beds. This method is very useful in the watersheds basins in which were performed the watershed practices such as Gabion dams and sediment ponds. This paper was the result of the research plan, which was considered as development of vegetation cover to biologically stabilize the tributary beds in Sardehat village areas as a split plot factorial statistical design. The three kinds of trees including: Almond, Elaeagnus, and Acacia as the main treatments, and the mixed of soil with manure and clay, and natural soil as the sub-treatments in three replications were studied in the selected area. During the performance of this study variables like stump diameter, height growth, and canopy cover were measured. Final results showed that considering the planting pattern Almond, Acacia and Elaegnus, and without considering the planting pattern Elaeagnus, Acacia, and Almond were preferred respectively in order to stabilize biologically the marl tributary beds.
