Abstract: 

Drought causes damages on rangeland ecosystems, which should be controlled by devising appropriate management measures. Prediction of necessary conditions and effective factors in sustainability of range ecosystem in drought conditions has a great important in management and mitigation of this phenomenon. Thus, the main objective of this research was the investigation and determining the overall situation and factor effecting the sustainability of range ecosystems in drought condition compared to rainy condition in Fars province, Iran. For this purpose an analytical – descriptive research method was used. Population of study included the rangers of Fars province, of which a sample size was taken by using multi- sampling method. Dependent variables of the study included the rangeland situation in drought and rainy conditions and sustainability threat of rangeland in drought conditions and the independent variables was factors affecting the sustainability of range ecosystems during the last five years. The findings of the research showed that there was a significant difference between thirteen indicators (out of fifteen indicators that were studied) concerning the degree of sustainability of rangeland ecosystems in drought and rainy conditions. The finding also indicated that drought had a significant effect on the sustainability of range ecosystem. Based on the research findings the dependent variables of the study including: types of range forage, type of range coverage, type of rangeland, the area of range, drinking water resources for cattle, residence style and the area of orchard garden effected the overall sustainability of rangeland ecosystem in drought and rainy conditions. The research recommended certain measures to be taken for the purposes of drought mitigation including: delivering extension and training programs related to livestock, range and drought, especially before the occurrence of drought, using the indigenous knowledge of range users and using the range in accordance with the principles of sustainable measures.
