Abstract

Assessment of diversity and species of richness in right understanding from ecosystem functions, protect and preserve genetic resources, evaluation and control of environmental change and help with the success or unsuccessful natural resource management programs. Intense grazing and without program of livestock one of the most common and perhaps the most of element rangeland degraded and reduced the DIVERSITY AND RICHNESS OF SPECIES. Given the importance and function of livestock grazing on qualitative and quantitative change of plant cover, the effect of grazing pressure in the three sites of REFERENCE AREA, KEY AREA and CRITICAL AREA on the DIVERSITY AND RICHNESS OF SPECIES with different LIFE FORMS in southern slopes of Damavand Mountain Summer Rangeland was studied. In each unit (site), sampling was donned along three transects of 150 meters.15 plots (square) with size of 10 meters located away from each other and in each plot type and the number of plant species and their percent have been noted. For evaluation of diversity criterions Past software used and computed Simpson, Shannon- Weiner diversity indices and Margalef and Menhing richness indices. Data analyses were performed in SPSS18 software and compare the various indices of diversity and richness between regions with different grazing intensities was performed via Duncan's tests. The results of this study showed that increasing the intense grazing, decreased from DIVERSITY AND RICHNESS OF SPECIES forbs and grass and shrubs were increased, so that in REFERENCE AREA forbs and grass with the highest and shrubs were lowest diversity and richness of plant. However, the duration and grazing repetition in the CRITICAL AREA, shrub species has the highest diversity and richness and greatly reduced diversity of forbs and grass species. Overall, in studied region, with increasing grazing pressure significantly lower DIVERSITY AND RICHNESS OF SPECIES that due to its negative effect on the stability of ecosystems should be of interest to operators, managers and experts range.
