Current research was performed in selected sites of mountain and semi-steppe rangelands of Iran. The vegetative region included Karsanak (Chaharmahal and Bakhtiari) and Jashlobar (Semnan). Astragalus effuses Bunge is a key and palatable species, having a considerable portion in rangelands production of the mentioned flora. For this purpose, 40 similar stands of Astragalus effusus were selected in each site. Selected species were exposed to different harvesting intensities of 25%, 50%, 75% and zero as control group. Data were analyzed by SPSS and MSTATC and Duncan’s Multiple Range Test was used for mean comparisons. Our results clearly showed that a harvesting intensity of 25% is recommended as the best allowable use for Astragalus effusus in this vegetative region and other similar areas.
