The present research was done in steppic rangelands of Dehno, Kerman province to study the
effects of different harvesting intensities of Artemisia sieberi applying simulation method. The
experiment was conducted using split plots in a completely randomized experimental design
of ten replications to find the best grazing intensity. Treatments are including no harvest (as a
control), 25, 50 and 75% harvest. In each treatment, 10 similar and average plant species were
selected as replications. All dependent variables were evaluated during the study and results
were analyzed in SAS software. Results showed Minimum and maximum forage production
was obtained at 25% harvest in 2008 and no harvest treatment in 2009, respectively. Regarding
to the obtained results and soil condition, the 50% harvesting intensity is recommended in
Dehno site to maintain the vigority of Artemisia sieberi that is not dangerous for its survival,
healthiness and vigority even in drought conditions.
