Abstract: 

Each plant species have due to the habitat characteristics, ecological requirements and specific tolerance with some soil properties. Siahboneh Rangeland was selected with about 5000 (ha) area in Haraz, province of Mazandaran for this research. The purpose of this study was to investigate the type of pollination, the distribution of species and some ecological indicators including humus, pH, nutrients, tolerance of salinity and heavy metals, variability of soil moisture. Field data were collected in the 2014 spring and summer. The plant species were collected and then identified based on families, genera and species using appropriate reference. Soil samples were taken from 0 to 30 cm depths of in each plot. In the laboratory, pH, humus, moisture, Salt, heavy metals and nutrients including P, N and K were measured. Then plant species were classified using Flora Indicative software based on ecological indicators. The results showed that 70.7 percent of species had dispersal using wind and 45.25 percent of them pollinate using insects. The tolerance of species in ecological indicators results showed that most species had high tolerance into pH, humus and nutrient. Also 131 species grown soil with low moisture in the study. Only 20 species had the ability of absorption of heavy metals in the study area.
