چکیده مقاله :
Plant Diversity conservation is a main objective in rangelandmanagement. Plant diversity is a suitable index for showing the changes ofvegetation in rangelands and has a high correlation with ecosystem parameters.Therefore, using this index it is possible to find the changes and manage theecosystem correctly. The current research was performed to determine the speciesdiversity in Fashandak rangelands of Taleghan. To do this, 110 plots each one withan area of 1 m2 were established based on randomized-systematic method anddensity of the species within each plot was recorded. Species properties includingthe related genus and family in addition to life form, growth form and biologicaltype were determined. Shannon, Simpson and McIntosh diversity indexes wereused. Results showed that diversity of Fashandak rangelands could be considered asmoderate. The highest distribution frequency was related to the species of Bromustomentellus, Hypericum perforatum and Thymus kotschyanus.
