چکیده

Plant Diversity conservation is a main objective in rangeland
management. Plant diversity is a suitable index for showing the changes of
vegetation in rangelands and has a high correlation with ecosystem parameters.
Therefore, using this index it is possible to find the changes and manage the
ecosystem correctly. The current research was performed to determine the species
diversity in Fashandak rangelands of Taleghan. To do this, 110 plots each one with
an area of 1 m2 were established based on randomized-systematic method and
density of the species within each plot was recorded. Species properties including
the related genus and family in addition to life form, growth form and biological
type were determined. Shannon, Simpson and McIntosh diversity indexes were
used. Results showed that diversity of Fashandak rangelands could be considered as
moderate. The highest distribution frequency was related to the species of Bromus
tomentellus, Hypericum perforatum and Thymus kotschyanus.
