This research carried out for 3 years in order to study minerals status of range plant in the different climates of Ilam province. There are 1700000 hectare rangeland in Ilam province and located in the Zagros central with 6 climates include middle warm desert(l), low warm desert(2), dry moderate(3), semi dry moderate(4), semi dry cooled(5) and semi humid cooled(6). The amount samples taken from different climates 1 to 6 were 6, 5, 3, 3, 7 and 7 respectively, along grazing season for 4 time each years. In each area range 3 stockman were chosen randomly and taken 15 plot(lxl) in their ranges. Samples after drying in room were mixed, consequently 124 samples analyzed basis of method A.O.A.C for minerals. The minerals were Ash, Ca. P. Mg, K,Fe, Mn, Cu and Zn. The results showed that climates had significant effects (p<0.01) on Ash, K, Mn and Cu, had not significant effects on Ca, P, Mg, Fe and Zn. Average of K, Mn and Cu were higher in climates 1, 2 and 3 respectively. There were significant differences (p<0.01) between 3 years for all minerals exception Ash. Average of Ca, Mg, K, Fe and Cu were higher (p<0.01) than the requirments of ruminants in all climates.
