Abstract

Iran has covered a wide range of vegetation is sagebrush, which determine the rate of exploitation sagebrush cover the management operation is necessary. This study is among the first efforts to determine susceptibility or resistance of key species in the grazing area has been done Khoshkrood Saveh. The treatments included four of the 25, 50 and 75% of control (no harvest) were. In each treatment 10 replicates were used as the basis of the species that depend on each variable is evaluated. Three years and each year to measure or estimate the visual characteristics of vigor and vitality, mortality, and the height of production was based. Results in a split plot design in time, in the three years (2008 to 2010) were analyzed using SAS software. Production of forage species Ar.sieberi showed that the effect of year, different intensities of harvest and their interaction is statistically significant at one percent. The intensity of the lowest in 2010 in 75 percent and its highest in 2008 has been in control. The average production (2008 to 2010) the decline has vitality and the intensity of the 50 and 75%, about 20 percent mortality was observed. Due to environmental changes affecting the management and pasture species, livestock grazing can be stated that 30 percent guarantee of survival in this region will A.sieberi.
