Vegetation is the most important factor in the sustainable and dynamic equilibrium of natural ecosystems. The study of vegetation is helpful in solving ecological problems such as environmental protection and natural resource management and environmental assessment. Based on the results of this study, it is possible to predict the trend of future changes in order to introduce the Landscape Vegetation of the step of Samamoos mountain of Rudsar in Guilan province. Referring to the reagent area and collecting its plants, it was using various sources including Flora Iran and Flora Iranica were accurately identified. According to the findings of this research, it can be said that altitude from the sea level has played a major role in the vegetation of Mount Samamoos. In this study, the division of the region into three belt elevations, including 2400-2600 meters (Ecotone region), 2600-3100 meters (semi-Alpine area) and 3100-3650 (Alpine area), Significant relationships have been observed in terms of species richness and elevation between different altitudes. These areas are the most important elevation slopes for large changes in vegetation, and sociological classes in this area change. On the other hand, these altitudinal bands are related to the main forms of vegetation in Alborz. Since grazing vegetation degradation, loss of biodiversity and the prevailing annual plants and thorny cushions. Asteraceae, as well as some of the non-palatable species of Fabaceae, have become widespread in the developing area.
