Knowing forage quality is necessary for assigning grazing capacity in range management program. For this aim, forage quality of two dominant range plants, Artemisia aucheri, and Peteropyron aucheri were studied in water spreading area of Heart station in Yazd province. Plant samples taken for two subsequent years from water spreading and control plots. Plant samples analyzed in laboratory and elements such as P, Ca, Mg, K, Na, Fiber, Fat and Proteins were measured. Statistical analysis indicated that in two years of study period, some elements has increased in water spreading plots (p<0.05), but, acceptable changes in forage quality of the two specie can not be reported.
