Range surveys in Iran have started in 1918. Research activities were held
in Homand Absard. Research Station locating in a semi arid
region and Nodehak Research Station in arid region. Range
research activities extended to 28 provinces of the country
since 1981. RRd currently takes the benefit from 88 senior
and 30 junior researchers working all over the country.
Creation of basic and applied information required for
application of proper range management is the core objective
of the RRD. To meet the aim, RRd has established two research
groups focusing on Range ecology and range management issues.
Rangelands are changed quantitative and qualitatively due
to variation of seasonal condition and management. Soil
and vegetation degradation in rangelands normally is a very
gradual process, not detectable major changes have occurred.
However, due to area of rangelands in country, they have
important role in economy, soil and water conservation.
Therefore lone-term ecological information combined with
precipitation records is important to determine the causes
of change in rangelands and to expand our knowledge of rangelands
including their variability, resilience and reaction to
management. This can be achieved by a long-term inventory
of most important factors influencing range condition, trend
and productivity. In addition; creating an range assesment
system, determination of long-term average production, establishment
of permanent key areas as a tool for other researches, important
of range scientists ability and their scientific communication
are other objection of this research project.
