چکیده

The range conditions explain its health as a management tool. Obviously, the
implementation of this important assessment requires the most appropriate study method
for each region. In order to select the most appropriate methods of range conditions in
Kabirkooh grasslands of Zagros in Iran, five estimation methods (i.e. six-factor, fourfactor,
vegetation and soil combination, value of pasture and climax) were studied in three
key and critical areas. In each area, five stations were selected using the randomizedsystematic
method. The differences between methods were analyzed using the factorial
experiment by the help of the randomized complete blocks design with five replications.
The results showed that there were significant differences (p<0.01) between both range
conditions’ determination methods and different areas. Regarding Kabirkooh rangelands in
current circumstances, four-factor method for semi-arid region is more applicable for the
range condition determination. Biomass production and range conditions had a close
relationship using Pearson correlation test (p<0.01, r=0.86).
